Solar panels for home

What is the Future of Solar Energy?

2012-01-09T14:47:00.000+02:00

Solar energy is an unparalleled source of electricity generation in a time of soaring demand and environmental sensitivity.

Thanks to government subsidies and advances in technology, the number and size of solar farms continues to soar. We have harnessed the power of the sun for years to warm our homes, provide light and most recently generate power. Still, solar power is but a small fraction of the U.S. energy mix.
Renewable fuels account for about 7% of energy supplies; of this, only 1% (0r 0.07% of total energy supply) is solar. Nonetheless, solar is getting a boost thanks to tax credits, new technologies and a desire to reduce our reliance on imported and domestic fossil fuels.
Still Solar Power is Pricey

Consider the newest solar plant to come on board in Arcadia, FL, a small community north of Fort Myers on Florida's southwest coast. The solar farm, boasting 90,000 solar panels, sits on 180 acres of land in DeSoto County. The farm is rated at providing power (about 25 megawatts / MW) to about 3,000 homes and businesses.

With a price tag of $152 million, this translates into a cost of around $50,000 per home/business.However, once built, other than maintenance and upgrades, the facility will keep producing about 25MW each year.

Thus, in 2 years, the cost per home/business is down to $25,000. In 10 years it is down to $5,000 per home/business, which could easily exceed total energy usage per customer for the ten-year period. And the farm keeps on producing thereafter.

Although initial start-up costs are steep, the benefits are enormous.
First, engineers, architects, construction crews and others have to plan and build the facility. Once built, at least a small group of people must operate it. So, it does help to create jobs.
Any energy it generates helps to offset the use of fossil fuels, a good thing for the environment, our overseas balance of payments and possibly even generating some political capital. When compared to wind power, however, solar is expensive and produces far less return on investment.

However, as solar sites grow in size (and each year begets bigger farms), the cost per kilowatt produced will surely decrease. Solar power can be harnessed across almost the entire U.S., large parts of southern and central Europe, Australia and even southern Canada.

As of this writing, the two largest operating solar farms overseas are in sunny Spain - Jumilla (20 MW with 120,000 photovoltaic panels) and Beneizama (20 MW with polycrystalline solar modules). Other large sites in operation include two in Germany (10 and 12 MW) and one in Portugal (11 MW). And a California company is preparing to install a massive solar installation near Sarnia, Ontario (across the river from Port Huron, Michigan) that will promises to be the largest photovoltaic solar installation in North America.

But, on the drawing board and/or under construction are even larger ventures - a 1 GW farm in China, a similar one for Australia and a 550MW farm in San Luis Obispo, CA. The push for solar (and also wind) is being driven by national and/or state requirements that a certain percentage of the energy used comes directly from renewable sources by around 2020.

While it is the larger solar projects make the news (often each news story heralding the "largest solar farm built in a certain area), many homeowners are installing solar hot water heaters, solar attic fans, and solar pool heaters. Some cities are even installing solar parking meters, while the San Diego Zoo sports a solar-powered trash compacter.

Since the sun shines daily, it really does make sense to harness its energy. The only question becomes, "at what cost?"

Reasons to Compare Gas and Electricity Prices

2011-12-01T19:39:00.005+02:00

Gas and electricity are the two most important utilities in our lives. Everything from household usage to business seems to rely on power generated by them. Today, life would come to a standstill without them. There are a number of suppliers operating in United Kingdom to meet the energy requirements of the country. British residents have the option to compare prices and choose their energy suppliers on their own. They can either choose different suppliers for gas and electricity or the same provider handling their energy requirements, often known as dual fuel contract.

The UK has a fairly free market that has become completely open for competition since 1999. This has promoted the trend to compare gas and electricity prices and switch energy suppliers. The companies keep offering attractive plans and tariffs for the consumers to entice them. More energy for less cost is the basic requirement of all consumers, which is well targeted by these companies. The charges of the suppliers vary from area to area, mainly dependent on the distance from the plant, the raw material required and the installation charges to that area. The consumer can compare gas and electricity prices of the companies and choose what suits them the best.

If you compare gas and electricity prices, the energy consumers in Britain are clobbered harder than any other country in the European Union. The price hike is almost twice than the other countries. Although the government is planning to launch new reactors to boost UK's energy reserves, the consumers also need to play their part and compare prices before selecting one, in order to make the most of their money. They also need to realize that gas is more energy efficient and inexpensive, so choosing appliances where gas can substitute electricity is also a better solution in addition to comparing prices.

As the market is flooded with so many tariffs and offers, most people get so confused that they would stick to some frontline suppliers. They hesitate to compare prices to consider better options. But doing some research on prices will help you to find the best deal in your area, and would save you money annually.

Thanks to the internet that has made things quite easier in every aspect, you can trade today while sitting on your comfortable couch. There are numerous sites that allow you to compare prices.

Solar Outdoor Security Lighting

2011-11-30T21:58:00.000+02:00

Solar outdoor security lighting comes in many forms. You can use as elaborate a display as you wish or have a purely functional, inexpensive system protecting your home and family.

There are several advantages to solar lighting. There is no expensive installation required. You can easily install motion sensor lights without hiring an electrician. Batteries do not have to be replaced frequently because they are recharged by the sun each and every day.

Since there is no electricity needed to power the lights, you will never see an increase in your electric bill. The solar panel that supplies the energy to the lights is easy to install and should be placed in full sun for the best functionality.

Kits are available that contain all of the necessary tools to install your solar outdoor security lighting. While most people believe you need steady sunlight every day to have your solar lighting panel work, that is not true. A solar panel can hold adequate power to function for approximately two weeks. The security of motion sensitive lighting can give the homeowner peace of mind.

The fact that a perpetrator triggers the light with the slightest movement in the vicinity of the lights, will startle them and often prevent further invasion of your property. Solar lighting can be spotlights, flood lights or LED lights. The choices for security lighting should be either flood or spot lights. They will ensure safety more effectively.

Also available is solar outdoor security lighting that turns on at dusk and turn off at dawn. This type of light is excellent for walkways, alleyways and other out of the way areas on your property. They will provide lighting throughout the evening. The built-in photocell detects light and dark. The bulb is saved by not burning during daylight hours. You will also have the ability to adjust the settings to better suit your needs if necessary.

While effective, there are those who prefer to use the floodlight as a secondary light in areas that have no electricity. They may not be as intense as electric lighting but will provide enough to have a protective effect.

If you consider the fact that the only cost is for the kit itself, it makes sense to double up in some of the darker, more remote areas of your property. In that instance the lighting would be comparable to electric lighting.

Ease of installation, inexpensive installation and minimal upkeep are three of the reasons to have solar outdoor security lighting on your property. You can use it to emphasize areas of your garden as well. There is a perfect spot that you may want to emphasize in your landscape, and solar lighting is a great way to show those areas off to your guests and for your own pleasure.

Consider all of the reasons to secure your property. Then look at the different ways to get that property secured. The cost of the system, the ease of installation and the lack of added expense should be all of the reasons that you need.

Or one can opt to choose the traditional reds and greens of Christmas. As for their design, they are offered in a string lighting style, or the icicle style, where one string of lights has many different lengths of strands hanging down from it at specific intervals of space, creating an icicle look when strung along the top of a house. Solar Christmas lights also come in a snake light format, where the lights are contained inside a plastic surrounding similar to a clear tube.

Most solar string lights use LED lights because they require less power and they last a long time. LEDs are a popular choice for many solar lights.

Shopping For Solar String Lights

Solar powered Christmas lights can now be found almost anywhere: at local discount stores, large warehouse stores, and online. Some popular locations to find solar powered Christmas lights include Target, Wal-Mart, Amazon, The Home Depot, and local stores.

These lights are available at practically any store that one would buy traditional Christmas lights from. This helps consumers by offering a large selection for them to choose from, and compare.

The Benefits

One benefit of solar powered Christmas lights is saving on electricity. Not only does this help the environment but it helps the wallet by saving a few dollars. One can decorate their house and still be festive while being economical.

These lights also offer a cordless free outdoor environment. While the lights are hung all around, there are no cords to trip over or worry about finding an outlet to plug them in to.

Solar powered Christmas lights work off of a small solar panel that collects the sunlight during the day and uses that power during hours of darkness. These lights can be useful in decorating places that are hard to access with power, such as the mailbox or walkway of a house. No matter which Christmas lights consumers choose to use, the solar powered lights offer the same type of quality and usage as traditional lights.

Top 10 Green Trends

2011-11-07T18:22:00.001+02:00

Green Trends

There is no doubt that 2010 was a difficult year for the economy, yet the hope for the coming year is high. And for good reason - Many leading U.S. economists predict that the economy will grow an astounding two to four percent in 2011. This is welcome news after two years of a painful recession.

What can businesses do to prepare?
What can executives, entrepreneurs and webmasters set in place so as to benefit from the projected economical growth of 2011? As economists begin to try and answer this question, we must first look at the possible trends and business motives that grasp the world economy. A common theme within the economy that has shown increased popularity is green technologies, products and services.

Why go green?
Because by "going green" we are protecting the environment. But an added benefit is that by going green, businesses are seeing long-term business growth and opportunity.

There are few segments of the financial system today that have shown continued growth during what economists call the "great recession". One thing is clear; the trend toward green technology is not fading. Every economic region has seen significant growth in the eco-friendly industry and companies are aware of the growing trend toward green-technologies. It is apparent that the green power movement shows no sign of decline. Indeed, the green movement continues to grow, despite the contraction in the economy since 2008. Green technology is one segment of the world-economy which has shown steady growth during the recent difficult economic times.

Green Trends and Predictions for 2011
This can serve as a guide for businesses as a place to prepare for green trends that will continue throughout the coming year.

1. Energy and Air Emissions
Many industries around the world are faced with two primary energy challenges: how to efficiently provide clean, secure and affordable energy and how to minimize the impact on the environment.
Two major power-hungry segments of the economy include:

Airline industry
Data center industry

Traditionally, these energy hogs utilized the most energy of any other industry in the United States and generated the largest carbon footprint. Business owners are looking for options within these industries that are more eco-friendly with a reduction in carbon emissions.

What to do?
Many companies that utilize a great deal of travel are looking for ways to not only minimize their carbon footprint, but also reduce their expenses. Companies are deploying various means of eco-friendly business models so as to reduce the amount of air-travel they utilize. And, in order to reduce the demand for power-hungry data centers, web masters, site designers and businesses are moving their web sites to green web hosting, which provides more efficiency and uses less energy than hosting in traditional data centers.

Telecommuting is becoming more popular among businesses with the use of VOIP services such as Press8 telecom. With the Press8 Hosted phone systems, companies are able to offer their employees the option of telecommuting - an attractive option because of high gas prices, nightly traffic jams and long commutes. Press8 phone systems offer methods to ensure employees working at home or from a remote office location are making productive use of their time.
Green web hosting among businesses is becoming more popular because it presents a clear solution for a reduction in the utilization of traditional, power-hungry data centers. Many webmasters are moving their web sites to companies that utilize green data centers. A word of caution: many so called "green web hosting" companies are merely web hosts that purchase Renewable Energy Credits (REC's) and then these companies market their services to the Internet community as "green". In order to be a "true" green web hosting provider, the web host must utilize a "green data center". Top web hosting firms offer green web hosting for personal and business web sites and hosts its servers in a "true" green data center.

2. Water and Wastewater
As part of a progressive replacement program, companies will continue to develop and install innovative water-saving technology and procedures. The challenge is to implement conservation measures to reduce water consumption, and thus the "water footprint" a company generates. Many strong industries within the economy are moving toward improving their wastewater treatment facilities. The investment is high but the payoff is significant.

What to do?
Companies can explore the option of updating their wastewater facilities. And those companies that do not have the resources for a large infusion of cash to update these facilities might consider outsourcing to treatment facilities that already have this technology in place. Many companies are implementing reverse osmosis systems which operate by pumping water under very high pressure through a semi-permeable membrane. Today's systems provide the same amount of water for only about 35 percent of the electricity consumption.

3. LED Lighting
Commercial, Residential, Marine, and Solar - each of these industries is seeing strong movement towards "advanced lighting". By upgrading lighting, these industries are recognizing substantial savings through alternative energy and efficient lighting. A leader in this industry is NeuTex Lighting and through their comprehensive catalog of advanced lighting products, companies and individuals are able to capitalize on significant savings in energy expenses by "going green".

What to do?
Before building a new house, commercial building, marine operation or solar configuration, consider speaking to your local city government about green building practices.

Neutex Lighting is a good source of information and their web site describes the ever increasing group of ways that companies and individuals can be less wasteful.
GreeningDetroit.com offers a unique directory designed to provide building solutions, products and services, green news and environmental responsibility options.

4. Eco-friendly automobiles
Trends in the automobile industry show strong growth in hybrid and fuel-efficient diesel engines. New product development with these types of engines is accelerating. Fuel-hogs such as large SUV's and vans are harder to re-sell and more expensive to maintain at the fuel pumps.

What to do?
Before purchasing your next automobile, consider a hybrid or diesel powered engine. The up-front cost is higher, but long-term savings in terms of fuel and overall maintenance is significant.

4. Reduction in waste
Consumers have taken notice and appreciate companies that produce products packaged in eco-friendly materials.

What to do?

Reduce, reuse, and recycle. The first step in managing waste is to reduce the amount of material used. To further cut back waste generation, companies can work with suppliers on container return programs. By recycling trash, companies are diligently working to decrease the amount of waste generated. Companies world-wide are showing signs of more often utilizing alternatives to packaging their products in materials that are harmful to the environment - specifically plastics. Consumers notice and show their appreciation with their wallets.

These companies are examples of cutting-edge corporations that are "going green" to reduce, reuse, and recycle:

Chantal Cookware, a major cookware manufacturer, encourages recycling in the day-to-day business operations at their facility and with their suppliers. For example, when shipping products Chantal only uses recycled paper and air pillows rather than cheaper Styrofoam pellets.
Thirsties, a company that manufactures modern cloth baby diapers, boasts the use of only the best made-in-America components in order to reduce their carbon footprint, to help support domestic textile mills, and to ensure diapers will last wash after wash. This company provides an excellent product that reduces the buildup of disposable diapers in our landfills.
WexelArt frames manufacturer produces art frames that can be re-used by simply removing the art and replacing with new art. The frames can also be used by companies to display brochures, promo posters, or sales and special offers. A genius product that allows companies and individuals to reuse frames for many different purposes.

5. Improvements in the food industry
Soy growth among farms across the world is showing rapid growth in this economy. Soy foods are a source of high-quality protein and has the potential to be a key source of income for farmers.

What to do?
Many farmers and food producers are developing management plans for sustainable growth and promoting standards and verification mechanisms which help to grow crops that are more efficiently utilized. The soy industry is showing significant growth because of the high nutritional components of soy. Many food manufacturers who are not yet involved in production of soy food materials are now exploring the options and benefits of including soy in their product line.

6. Higher use of post-consumer recycled fiber
Consumers appreciate the use of post-consumer recycled fiber in packaging and its use among responsible corporate entities is growing.

What to do?
Many companies are utilizing 10% post-consumer recycled paper. Examples include coffee cups at your favorite coffee shop. Consumers notice and companies will continue to explore the benefits of higher use of this renewable resource.

7. Higher use of recycled rubber materials
Used automobile tires liter landfills and are among the largest and most problematic source of waste at landfills due to their large volumes. Tires can be recycled for use on basketball courts, new shoe products, hot melt asphalt, and recycled asphalt pavement - among other things. Industries that recycle these materials and re-use them in construction are showing strong growth.

What to do?
Where there is growth, there is strong interest. Companies might consider researching possible use of these types of materials in the construction of their products and market them as "recycled" automobile tires. This benefits the environment and benefits the companies that recycle them in terms of possible economic gain.

8. Higher incidence of recycled batteries and computers
Companies are more and more often recycling old computers when they are replaced with better and faster machines. Apple recycling program, HP recycling program and Dell recycling program are among a few of the top programs that offer this service.

What to do?
Companies can utilize these services and consider advertising to their consumer base that the company participates in programs to recycle used computers in an effort to reduce landfill waste.

10. Clothing material trends
The fashion industry is seeing strong trends toward renewable resources such as eco-friendly bamboo. Not only is bamboo considered one of the most renewable resources in the world; it is also one of the softest materials, even more so than cotton.

What to do?
Companies that are involved in the fashion industry should take note of this growing trend and explore the possibilities of including these items in their product line.

SavageDesigns - an ecologically and socially conscious clothing and design company that is committed to increasing the health of its consumers by providing healing clothing with nettle fibers.
Cariloha - bamboo clothing manufacturer that offers franchising opportunities for entrepreneurs.

Green marketing for business
Along with the rise of green consumers, we see the rise of eco-labeling, which is "green advertising". That creates the opportunity for just about anything to be marketed as green. It is important that the marketing strategies that companies use are "true" and companies that market their products and services as eco-friendly are indeed "green". This article can help entrepreneurs and business owners find "true green" companies and services for the growing eco-friendly economy.

Solar Panel Business Opportunities In Asia

2011-10-02T22:54:00.003+03:00

Anyone who is even minutely aware of basic economics would understand the working of supply and demand. The higher the demand the higher would be the supply. And this theory has worked for manufacturers for years and years. Businessmen all over the world keep an eye out for an increase in the demand of something, and they start manufacturing them. The profit is there and so is the consumer satisfaction!

Similarly, in the case of energy production, businessmen should keep an eye out not only in the most recession hit countries, but all over the world. In Asia, many countries are excessively using things which can result in an individual market of solar panel productions. For instance, the use of automobiles has increased highly in India, that too amongst the middle class residents. The purchase and daily usage of automobiles by middle class citizens alone requires enough money to be spent on. The daily usage of fuel not only costs them much, but is also making the environment unhealthy and unfit to live in. This affects kids and adults alike and causes the increase of infections and airborne diseases that damage the lungs.

In the same way, the situation in China is the same. People are opting for automobiles to travel around and the usage of fuel is responsible for the increase in its prices; well, that is also because fuel is more difficult to obtain these days. Thus, this is an excellent opportunity for businessmen to market the usage of solar panels to these people, so that instead of throwing away their money on fuel, they can get their cars running on solar power. Not only would it cut their costs, but it will also provide a better environment for their kids to grow up in.

Here's a site I have found very helpful for my own Solar Panel venture.

I highly recommend it for any person wanting to build professional and integrated solar panel system from scratch. Good luck!

So first things first; you need to know where your money goes. Is it for purchasing necessities? Paying bills? Buying luxuries? You need to know how much comes in and how much goes out so you can see if you can really save.

Collect and save all receipts-from groceries to coffee break snacks-for a month or two in order to see the big picture on your expenses. Also make sure to include any other regular expenses such as personal loan repayments. After you've done that, make a simple list of income and expenses. Keeping track of your purchases will lead you into phase two- making a good budget plan for your household.

Once you've made your list, sit down and analyse it. Separate your needs from your wants - your necessities from your luxuries. You might need to be brutal when deciding what you can spare.

If this is all too boring for you, think about buying personal budgeting software to help you out. Many financial websites that offer online money solutions also provide free online budgeting resources and spreadsheets to aid the process.

You've weeded out the culprits, now it's time to reassess. One of the major players when it comes to monthly household bills is in fact the energy bill. While there is not a lot of room to move, you still have some options. Before you imagine yourself washing your clothes in the swimming pool or living by candle light like cave men, brace yourself for the words... "green" appliances. Yes, these environmentally-friendly appliances can be a little more expensive than the average brand at the checkout, but it will save you a lot in the long run. Why? Green appliances-usually washing machines, refrigerators, television sets and light fittings-need less electricity to function at maximum capacity. Just look out for the energy star rating sticker next time you're in store. It is the easiest way to work out how energy efficient and therefore money saving each appliance is. You can even sell your old appliances in the comfort of your own home through online marketplaces such as eBay or Gumtree.com. It couldn't be easier.

How about saving on food? Groceries can be a rich source of savings. It is one of the easiest and most logical ways to get some immediate cash flow. Avoid eating out often and get back to basics with the meals you cook. Soups are cheap and easy to make in the winter while salads are a quick and cheap solution in the summer. When stocking up on food, read the ingredients on similar products. You can slash a whopping 40 percent savings by choosing another brand which has the same ingredients but is cheaper.

Finally, get rid of that credit card! It might not be something you want to hear, but because credit cards work on a rollover system, you may never see the end of that bill. Although we all know that if you pay your bill each month you wont accumulate interest, how many of us actually demonstrate the self control to do that? If it doesn't cause you any problems, then its fine to keep it for those days when your paycheck doesn't quite make it to the finish line. But if you find yourself continually dipping into the credit card pool without giving any thought on paying it back- it has to go. An alternative for those weeks when you do run short is a small personal loan called a cash advance. While they are more expensive than your credit card in the short run, it could save you thousands of dollars in the long run.

Look for companies that charge flat fees and don't offer rollovers. That way you'll only borrow when you really need to, and will have a pre-determined repayment schedule.

The bottom line? Be savvy with your money. If you're up the creek without a paddle, don't pretend like you're on a 5 star cruise liner. Be honest with yourself about the situation and take the necessary steps that follow. Good luck!

What About the Jobs Crisis? Two Words: Clean Energy

2011-09-29T21:42:00.002+03:00

When legendary Chicago newspaper columnist Mike Royko wanted to dig deep into a meaty subject, he'd ask Slats Grobnik's opinion.

This usually took place over beers down at the bar.

Slats, fictitious but possibly based on a composite of Royko pals, would give an unvarnished everyman opinion. This week he'd likely say, "Congress? As if they've got a snowball's chance of fixing the economy.

Grobnik's take on the economy

"We need jobs. Mel's wife's car broke down. He's not getting enough business at the diner to pay the mechanic. The mechanic's not ordering parts from Irish Lou. Lou's thinking about closing shop.

"Look at me. I'm still on my first beer, and it's about time to go home. What kind of austerity plan is that?"

Grobnik didn't sugarcoat. He made it real. He gave Royko the essence of an issue.

Straight-up perspective

I don't have a Grobnik, but I do believe the economy could use his straight-up analysis. The economy is so complex these days that just a quick update of Wall Street daily turmoil requires international monetary background.

People like Grobnik care more about finding a way to keep their houses from foreclosure or families fed more than bank bailouts, tax breaks or other government manipulations.

They just want jobs, not daydreams.

The Great Depression had World War II to bail it out. The war was drastic and deadly but hugely effective in getting the American machine firing on all cylinders. Our more recent forays into the Middle East have proved more financially draining than effective.

Mitch Yossarian weighs in

My version of Grobnik is a friend at the health club. (Yep, health club. Royko would shake his head with disgust.) Mitch Yossarian, a fictional Fresno, Calif. developer, mentioned high-speed rail. He just returned from a trip to Europe crossing more than 200 miles of the continent from Brussels in less than an hour.

"In California, it won't pay off right away. But all sorts of things would grow around the stations," Mitch says. "Plus, it creates jobs."

I nod, then mention solar projects. "Certainly," Mitch says.

Give the sun a shot

Solar is about to catch fire, metaphorically, in the San Joaquin Valley. Developers have proposed thousands of acres of photovoltaic panels to capture the energy of the sun. Once started, these projects should spur spin-off activity with each solar dollar multiplying at least four-fold as it circulates.

Angel, the out of work farm hand, could get a job after completing the Proteus Inc. solar training program. He'll be able to keep the car. He'll go out to eat.

Solar, like anything in the renewable energy realm, remains controversial. I just spotted a political cartoon that showed officials ready to unplug a generator that symbolized tax dollars. That generator fueled workers putting up solar panels.

But solar is nearing parity with other forms of electricity. Soon it won't need any subsidy to compete. Nor will wind and a host of other forms of clean or cleaner energy.

Energy efficiency works too

Already the value of energy efficiency has stormed Wall Street, creating an entirely new sector of jobs under the sustainability banner. U.S. Green Building Council's Leadership in Energy and Environmental Design, or LEED, program for either new construction or retrofits of buildings is growing and shows no sign of wavering.

Energy efficient buildings just cost way less. The Empire State Building is a shining example. For about $13 million in "energy specific measures," owner Anthony Malkin told Christina Nunez of

National Geographic he reaps $4.4 million in annual savings. The measures were part of a larger $550 million upgrade to the New York landmark. The building rates a LEED gold.

Stories like that inspire others.

Energy efficiency by itself won't pull the country out of recession or inspire Grobnik, or my friend Mitch, for that matter. It will put plumbers, electricians and construction types to work, however. And that's the important part.

Headed in the wrong direction

But the economy's going to need more. I came across a story on National Public Radio's All Things Considered during which New York Times columnist Tom Friedman is quoted as saying the United States lost its way the past decade.

"We misread our environment," he tells NPR's Robert Siegel. "We thought the Cold War was a victory and we could put our feet up."

However, lifting the Iron Curtain and normalizing relations with former foes tossed another 2 billion people into the world economy competing at every angle with U.S. ingenuity, says Friedman, pitching his new book, "That Used To Be Us."

Now those competitors are just running faster, he says.

Something from D.C.?

Solutions to the jobs crisis will be bandied about Washington, D.C. for many months. I don't hold out too much hope for government-generated help. Friedman says curbing political gridlock would do wonders. That feels like saying maybe pigs could fly.

President Obama proposes a $447 billion jobs plan, but its reception from across the aisle is cool. Presidential hopeful Mitt Romney, who says he spent more than 25 years in the private sector for street cred, unveils a 160-page jobs plan that even the Wall Street Journal says is "surprisingly timid."

Texas Gov. Rick Perry has a pitch that may resonate with voters but is sorely lacking in substance. In a recent conversation with Sean Hannity he says, "You free the entrepreneur, the small business man and woman, or for that matter the Wall Street investor, from the over-regulation and the over-taxation and Americans will go to work tomorrow."

Sounds good. But I recall what happened the last time a freed Wall Street created toxic mortgage soup and a global financial meltdown. My house went from a $269,000 2005 sale price to a value of about $120,000 (maybe).

Keep it real & green

I'm putting my faith in green. We've got an army of entrepreneurs motivated not only by making money but making the world a better place. The spiraling costs of pollution will become frighteningly obvious very soon, making everything clean energy more valuable.

And that will create jobs. Sustainable jobs. Different jobs.

I just wonder what they will be. And whether there will be enough to go around.

Renewable Energy in China - Serious Opportunities or Serious Risks?

2011-09-25T18:43:00.007+03:00

China is now the world's largest investor in renewable energy having eclipsed both Germany's and the United States' spending in the last year. Renewable energy is at the heart of the latest (twelfth) five year plan for the development of China, and there's been an explosion in companies focusing in the sector. Solar, Wind, Hydro and even Geo Thermal have become big business for the Middle Kingdom, and foreign investors are rushing to get in on the act. However much of the money flowing into the sector may not be wisely spent, the question is how to identify opportunities from major risks?

Solar

Solar is a troubling area of renewable investment, the whole world is chasing the "free" energy supplied by the sun's rays. However current technologies are terribly inefficient and there's a huge glut of production capacity which has led to the commoditisation of the solar market. This is good news for consumers because pricing is heading down thanks to intense competition, but bad news for investors who may be worried about when they'll see returns.

A good look at the fundamentals suggests that many of the smaller players are likely to go out of business, particularly those who only offer production capacity without any significant research and development divisions. Larger more established players should be able to ride out the storm though and benefit from the closure of smaller players by buying up facilities and equipment at fire sale prices.

As production is currently far cheaper in China than elsewhere, the best bets are global companies (owned by any of the major renewable energy countries) with production facilities in China and strong research and development facilities in Europe, the US or China.

Wind

Wind power has also reached the commoditisation state and while there are fewer players in the game than in solar, there's still a reasonable amount of over capacity in production. Wind is also suffering in the market due to the noise of onshore farms and the costs of offshore farms.

With China committed to large investments in offshore beginning in Shanghai later this year, it's likely that the main spend on this technology is likely to originate in the Middle Kingdom and favour large companies either locally owned or joint ventures with strong government ties.

Smaller producers are likely to suffer, particularly with higher levels of scrutiny promised for farms that were previously not vetted due to their low production capacity.

Hydro and Geo Thermal

Both of these technologies are necessarily self limiting and the markets for these energy sources are more or less mature. Hydro in particular can be damaging to the environment and is of necessity an unattractive option in many market places. The established players should continue to show reasonable returns and those that pay enhanced dividends may be worth watching, but there's unlikely to be any major growth in this sector in the long run in China though Chinese companies may benefit from implementation projects in Africa where the government has strong ties with African powers.

Ultimate Report Of Nikola Tesla Secret

2011-09-24T02:13:00.009+03:00

The way to use free energy is a secret, but it is now revealed for whom is reading this article. Although people have searched for the appropriate source of energy to use, for example: solar energy,
wind power, etc, they have not found a perfect answer. Yet, there is one kind that would save you a great amount of money when using it. What you need is just 100 dollars to buy the necessary things from your local store.

You haven't heard of it because it is a secret. The investors were afraid of the threat this device may pose to other energy companies so they kept it in the dark for 90 years. Actually Nikola Tesla had this idea way back in 1934, and he announced that "I have harnessed the cosmic rays and caused them to operate a motive device".

The investors at that time were afraid that this device would put an end to the billion dollars industry. With the withdrawal of them, Tesla could not complete his project and all of his files were seized and never released. It is not until now that a group of scientists found Tesla's files and continue his work. They did not keep those for themselves but have shared those documents with the following steps. You can build your own household-seize generator to use at your home which can supply electricity for your TV, fridge, washing machine, etc.

Even if you are in mountainous area, you can still use this generator when you do not want to use sun energy. You can also bring it with you when you go camping. Now you are able to use electricity devices like light bulb right in the nature. And the most convenient thing about this device is that you can build it when you have spare time.

Discover How to Use a 100 Year Old Device to Throw Your Electricity Bill Out the door. Tesla's Secret Device is a proven and effective way of generating FREE Electricity-and help the Environment.Click to explore the big bonus from Nikola Tesla Secret

Multijunction Solar Cells - Technology Imitates Nature

2011-09-23T10:28:00.001+03:00

Remember your basic Biology 101 and photosynthesis?

In case you need a refresher on the topic, photosynthesis is how a plant converts light into energy, which it uses to run its metabolic processes. Multijunction solar represent the mechanical, artificial analogue to this biological process. But before we get into that, let's take a look at your basic solar cell.

It's Been Around Longer Than You Think

The idea of generating electricity using sunlight dates back almost to the time people started using electricity. In fact, a photovoltaic effect was first produced around 1840 - not long after Queen

Victoria ascended to the British throne. However, it was another fifty years or so before someone actually created a working solar cell, and another twelve years before Einstein was able to explain how it worked (he won the 1921 Nobel Prize for that). The first modern multijunction solar were made just after World War II.

In simple terms, a solar produces electricity when sunlight (photons) hit the surface. This sunlight is absorbed by a semi-conductor, usually silicon. This causes electrons, the subatomic particles that carry a negative electrical charge, to come loose from the atom, which ultimately produces electrical current.

The Problem - and Solutions

The problem with those silicon flat-panel solar arrays is that they aren't terribly efficient. However, a cpv solar cell array can have an efficiency rate of over 40%, meaning that two-fifths of the light that hits the surface is converted into electrical current. This figure is going up, and within the next year or so, a cpv solar cell array will have what is called grid parity with today's fossil-fueled power plants, meaning that a grid of solar cells will produce the same amount of energy as an equivalent fossil fuel setup.

The secret is that new solar cells have multiple layers, each of which captures a different part of the light spectrum. As you probably know, sunlight contains several different colors, which we cannot perceive until that sunlight is broken up into its components by a prism, such as a crystal or water droplets. You see the different parts of the spectrum when a rainbow forms in the sky after a rainstorm.

Regular solar cells with a single layer are only able to capture part of the spectrum; CPV cell layers are "tuned" specifically to capture the entire spectrum.

Efficiency is further increased in an array using concentrated photovoltaic cells, in which various devices - such as mirrors and fresnel lenses - are employed to increase the intensity of the sunlight hitting the surface.

The Nanotechnology Solar Cell Revolution

2011-09-21T12:40:00.001+03:00

There is little debate that we need to wean ourselves off of fossil fuels, but the costs of renewable energy platforms such as solar make it difficult. Nanotechnology definitely offers the answer.

Solar power is considered one of the better renewable energy platforms. Enough sunlight hits our planet each day to meet our world wide energy needs for an entire year. On top of this, solar energy is a free power source, since nobody can corner the market on the sun. Solar power is also good for the environment since it produces none of the emissions that are of such concern today, specifically carbon dioxide greenhouse gases.

If solar is so great, why don't we see more practical applications? The problem lies in the applications. Specifically, we have no way to harness the power. Commercial solar cells are very inefficient. Current models on the market only convert about 8 to 13 percent of the sunlight hitting them.
This inefficiency makes the cost of producing energy via solar platforms too costly. So, what can we do?

Nanotechnology is a new scientific field with many applications. Although the media has hyped the technology as the answer to a wide variety of miracle cures, most scientists and companies are looking to more practical applications. One such application is improving the efficiency in solar cells.

Nanotechnology has already shown huge breakthroughs in the solar field. In certain studies, the use of nano applications has improved the conversion rate of solar cells to an incredible 65 percent, a slight increase over the current 8 to 13 percent rate. Although none of the applications are currently refined enough to be turned into commercial products, they are getting close. Let's take a look at a one of the approaches.

Quantum dots have the potential to change the world. They are a form of solar cell that is completely beyond anything you might imagine. Traditional solar cells produce electricity in a unique way. When the sunlight hits material in the cell, the material kicks of an electron and the charge is the electricity. Quantum dots work the same way, but they produce three electrons for every photon of sunlight that hits the dots. The dots also catch more spectrums of the sunlight waves, thus increasing conversion efficiency to as high as 65 percent, a stunning figure.

The really interesting thing about quantum dots is they do not require big, bulk solar panels to work. Researchers are combing the dots with liquid polymers. In practical terms, this means they can be sprayed onto any surface. This literally means that anything painted can act as a solar cell. Think about that. In the near future, you will be able to go solar by just repainting your house. Hybrid cars will be revolutionized, so will your mobile phone. On a cold day, you can put on a coat and gloves that are heated by the solar cells imbedded in their surfaces. The scope of this breakthrough is as breathless as it is unlimited.

Let's face it. We need to make changes to the way we produce energy. It appears as though nanotechnology may convert solar power from an iffy solution to a definite one.

Solar Energy - Why All Eyes Are on Israel

2011-09-11T14:57:00.002+03:00

In the UK, solar energy is still something of a confusing answer to the problems posed by our ever-dwindling fossil fuel resources. This confusion is unsurprising, our northern European climate is rarely associated with scorching heat - and a quick look at our landscape and coast shows ample area for wind and tidal power. Yet, in recent times the increasing affordability of solar hot water and proof of the benefits that come with it is causing more of us to consider installing solar collectors. But to really keep abreast of the developments in solar technology, we can learn the most from Israel.

This may be surprising to some. By comparison to the United States etc, Israel is by no means the richest country in the world so how can they afford to be at the forefront of a technology that is widely considered so expensive? Well, this goes some way to highlighting just how affordable such technology is today, and in a country that is blessed by more than 300 days of sunlight a year - they have been benefiting from solar hot water for over 50 years.

In the 1950s an Israeli fuel shortage stimulated entrepreneurial engineer Levi Yissar to invent a solar water heater, which became a commercial venture by 1953. By 1967 one in 20 Israeli homes were using the heaters and 50,000 had been sold. Demand dropped over the next few years, but picked up again due to a national energy crisis in the 70s, pushing the Israeli government to pass a law assuring that every new home was built with a solar water heater installed.

Since then the country has grown to become the world leader in solar production - with the Ministry of National Infrastructures estimating that solar saves Israel around two million barrels of oil a year. However, despite the abundant amount of sunlight and the long-established use of solar for heating water, Israel is also at the forefront of making solar ever more efficient - to the point of matching fossil fuels.

In a report at NPR, David Faiman of Ben-Gurion National Solar Energy Centre highlights the problems with solar. "Solar energy is a very dilute form of energy compared to fossil energy. If you take one metre of the sun rich Negev desert...it will take nearly a year to absorb from the sun the equivalent of one barrel of oil, and mankind is currently consuming energy at the rate of two hundred million barrels a day." Despite this, Israel's work with concentrator photo voltaics technology is speeding up the process - producing 1,500 watts of electric power from just a four inch by four inch solar panel.

Solar Power For the World's Poor

2011-09-08T08:44:00.001+03:00

Solar power as a renewable energy is gaining more and more momentum every day. While here in the United States we normally think of either small self-contained residential and business installations or large utility supplied systems, there is a great potential for solar power electricity in developing countries.
It boggles the mind to realize that nearly 44 percent of the developing countries in Africa, Latin America and Asia have no access to electricity and only 1 percent of the world's solar panel production has been installed in such countries. This could change considerably within the next ten years.

The main issue for bringing solar power to these areas is of course how to pay for it. Around 2 billion people live in rural areas with no electricity. Even though most of these folks are poor, about 40 percent of them are spending $5 to $10 per month for lighting, mainly through kerosene burning lamps. Individual solar installations could be less expensive than building up the infrastructure for conventional power lines, especially in areas where buildings are far apart. While the cost of equipment is reasonable, it is the construction, installation and on going maintenance infrastructure that is usually the most challenging.

There are many alternative systems becoming available but two have caught my attention recently.
The first is very simple and at first glance doesn't appear to be worth much until you realize that the only light at night for many of the world's poor is from a fire or a kerosene lamp. The smoke and fumes from these lamps are a great health issue not to mention the pollution. There are organizations that help set up, educate and finance micro businesses to convert kerosene lamps to electric lamps. They install a small solar panel, battery and light-emitting diode lamps. The families pay for the conversions and future battery replacements from their 'kerosene budget' which can now be greatly reduced since sunlight is free.

The other system is a prepaid system where solar panels and associated equipment and batteries are installed at homes along with a card reader. A local 'solar store' sells electricity credit cards to the home owners. The store has equipment to reload the cards and to monitor usage to foresee future battery replacements. The home owner swipes his card to use electricity from the system. These systems typically cost around $200.
These are only two ways that electric power is being provided to the poor. As infrastructures and government subsidies are established there will be more investment in these developing world areas. Also DIY (Do-It-Yourself) Solar Power will play a larger role as local people become solar power literate.

Bridging the Gap Between Going Off The Grid and Surviving

Going off grid with solar--and batteries

Living Off the Grid in Style: An Interview with Super-Homesteader Jane Dawson

I am not really sure what is happening in this country. Five years ago the economy was incredibly strong, the housing marketing was doing very well and most people had equity in their homes.

Like a great many people you probably bought your house while the market was on that upswing anticipating that it would continue to increase in value. And it did for a while but the economy tanked. I don't know about you, blaming the politicians is fun and it makes us feel better, but there comes a point when we have to take matters into our own hands. I needed to start saving money, like now! I can't wait for things to turn around. That's why I made the decision to learn how to build solar panels.

I looked into the cost of buying panels for my home and I just couldn't afford them. I work hard. I don't spend more than I earn. I am not different than most people. I have accepted that the economy might not change or bounce back. But quite honestly, I don't want to take the plunge to go off grid entirely. I like my life. I don't like paying through the nose for my electricity. Once I learned how to make solar panels and install them myself, my bill went down. Most months I don't even owe a dime on the bill and some months I get money back from the power company. This wouldn't have happened if I hadn't learned how to build solar panels and learned how to save energy. I was like you, living paycheck to paycheck.

I am frugal and make sure I turn off lights when I leave the room, but somehow that wasn't enough. My bill was still creeping up month after month. So I did a little research on the Internet. I typed in, "How to Build Solar Panels." At first I worried that I'd come up with all these companies who were happy to sell me solar panels at tens of thousands of dollars. But to my pleasant surprise I found a site that really helped me learn how to build solar panels.

I wanted to save money doing it too. Learning how to build solar panels for me isn't about spending a whole lot of money and time doing it. If I had all the money that these celebrities have, I could just call a company, schedule a date and have them come out and install a bunch of panels. Now, that's not me. I am pretty handy and I built my own shed for tools and so I knew I could learn how to build a solar panel.

I live in the suburbs. I have a modest house, an economical car. I am not showy or flashy. But I won't lie to you. I love when people come over and compliment my solar panels. I sort of feel like I live off the grid even though I live in the burbs. Why? Since I learned how to build solar panels and I installed them myself, I watched my electricity bill all but disappear. First it dropped in half. Next month I owed literally a dime and by the third month it was a zero balance and now? I even get reimbursed by the power company sometimes. So I feel like I am off grid even though I am suburban homeowner. But if I hadn't learned how to build solar panels, you know where I would be? In the poor house for certain!

Learn all of the great secrets to build a solar panel at home! Don't miss the golden opportunity to become part of a green community that will save you money and the environment. Go to http://www.howtobuildsolarpanelinfo.com

The Current Situation of Solar Energy in USA and Japan

2011-09-04T07:22:00.002+03:00

Solar is a sustainable use of clean energy. In the search for sustainable development of human society, energy-saving building on the increasing use of solar energy is getting worldwide attention.

The status of solar energy use in United States is getting better!

In United States, total energy consumption in building comes up to 30% -90%. It is becoming a certain form of economic development constraints role. Therefore, American development of solar energy is growing very rapidly.

In order to reduce energy consumption, reduce pollution and adjust energy structure, to achieve sustainable development, United States made a positive exploration of solar energy. "A million solar roofs plan" is the largest in the progressive realization of the project plan.

The U.S. plan is geared to the 21st century by a government advocacy. It is a development of medium and long-term plan. By implementation of this plan, there will be 1 million roofs or buildings installed with solar energy systems, including solar photovoltaic systems, solar water heating systems and solar air heater system. By implementation of this plan, solar energy technology applications will be further expanded, to reduce greenhouse gas emissions, expand energy choices and create new high-tech jobs. It will bring substantial environmental benefits and economic benefits. By 2010, millions of the roof will be equivalent to production of 2-3 coal-fired electricity power plants. It will not only meet their own electricity needs, but also been able to sell electricity generated by solar energy.

Recently, U.S. scientists find new energy from the vastness of space. Scientists envisaged launch the satellite energy collecting device. The solar panel installed in the satellite can collect energy in space, and the collection of energy as microwave will be transferred back to Earth, and then converted into direct current. It will provide cheap, clean, safe, reliable, sustainable energy.

Japanese current situation in construction of solar energy utilization is very nice!

As the second-largest economy, Japan is the primary energy consumption in major countries, and they are depending on energy imports. However, in recent years, Japanese energy-saving technologies to significantly improve energy efficiency are getting better rapidly.

In the field of solar energy use, Japanese photovoltaic roof system were installed 887,000 kilowatts by the end of 2003.Japanese government plans to install 4.82 million kilowatts by 2010.

In Japan, solar energy is very common in ordinary residential quarters. The residential quarters of the energy conservation efforts is clearly promulgated by the Japanese construction regulations and standards. There are many specific energy-saving measures for lighting. In energy-saving, the Japanese residential quarters are in the common application of solar energy, and it is mostly passive solar house system.

Absorbing through the roof panels that efficiently collecting solar energy, it will enter the indoor with thermal (cold) wind according to interior rooms automatically. It can supply hot water as well. The utilization of solar energy in Residential Area can not only save power, but can also improve, protect the environment. It is also in line with community building in the sustainable development of energy-saving in one direction. It is getting Japanese government's attention, Support and encouragement.

These two countries are all doing very well in the solar energy industry. Their scientists are working very hard on this solar energy development as well. There are still a lot of obstacles in the development of solar energy. In the near future, the solar energy utilization will be more important as the shortage of oil. So it is time for us to pay attention to this industry!

Build Solar Panels - Is it Really Worth it?

2011-09-03T17:31:00.002+03:00

Do you remember when you were a young kid and you were focusing your magnifying glass on a bug in the hot, noon-day sun? When you did that, you were concentrating the sun's rays and creating solar power. You probably thought it was just being a little bit naughty, but what you were doing was a precursor to today's modern solar power panels.

You can build solar panels at home and do more than cook some defenseless bugs. You can generate power for your appliances, heat your water, and even send power back to the electric company for them to sell (at a profit!). When you build and install a solar panel system you will see your utility bills plummet quickly and forever.

Sure, you are probably thinking that you don't have the skills or education to build solar panels, let alone install them, but you could be wrong. There are kits and instructions available that just about anyone can utilize, giving you the ability to build your own power system almost immediately. It isn't rocket science, it isn't that expensive, and you can start to realize a reduction in your electricity bills the very same day you have the solar panels on line.

Of course, just being cost-efficient is only part of the benefits of alternative energy sources. If you build solar panels and install them on your home you are doing something wonderful for the environment. By generating power without using foreign oil or domestic air-fouling fossil fuels, you are keeping the atmosphere cleaner, the earth cleaner, and providing a healthier future for generations to come.

And don't forget that the government appreciates it when you create your own energy.
It loves it so much that it offers rebates and tax deductions to those homeowners who install solar panels and other alternative energy generation devices. Isn't that great? Not only will you save money on a long-term monthly basis by lowering your bills, but your tax burden will be reduced, as well.

Home solar products were expensive in the past and not easy to install.

These residential solar products, built by engineers and mounted by construction crews, were restricted to very wealthy people with environmentally- conscious minds. For the rest of us just normal people who wanted to conserve money and do some good - home solar products were out of the question. But since it is now possible to build solar panels on your own and cheaply at that, this just might be the time to roll up your sleeves and have a go at it.

Super Solar Power Project

2011-08-25T11:42:00.001+03:00

Giant solar power project.

Many people have heard of the solar tower project being constructed in Australia. It is over 1000 meters tall and will produce 200 mega watts of electricity by heating air at ground level which then causes the air to rise in the tower. It also serves as a green house. It is slated to go into operation to power about two hundred thousand homes in 2012. Spain has a prototype that is functional and has already been tested near Madrid.

There are as well various photovoltaic solar fields with arrays of solar panels that generate electricity directly from sunlight. The most popular large scale solar power projects are by way of the solar trough or parabolic trough system which concentrates solar heat to a focal point which in most cases is an oil filled pipe. The oil is heated to around 700ºF where it is pumped back to a heat exchanger which creates steam power.

The goal of all of these technologies is to reach a higher level of efficiency. Currently the most efficient system is the Solar Dish which has reached 30% unmatched by any other technology. Well hold onto your hats because what I am about to tell you here could probably double that or more.
The new system

What is proposed here is something that combines existing technologies and creates multiple sources of energy from the same plant. First we change the parabolic troughs into solar tubes; the bottom half being reflective and parabolic in nature; the top half glass Fresnel. This accomplishes two things: first the tube actually concentrates even more sunlight upon the oil pipe, second now we can pipe to the solar tubes cooler air from under ground, the air is then heated to high temperature as it flows along.

When the super-heated air reaches the other side of the solar tubes it is then directed up to the top of a hill where it is released into a super efficient vertical wind turbine that makes use of magnetic levitation which will produce electrical power. The super heated oil or other liquid is then pumped to an efficient heat exchanger which transforms it into steam power through a turbine system. And now the third source of solar energy is employed in the tube by way of reflective yet absorbent gallium arsenide solar film which would create high temperature photovoltaic electricity directly.

We can then store the excess super hot oil or other liquid substance below ground in a well insulated storage tank so that the system can continue producing steam power at night. As well any excess power production not being used can be utilized to electrolyze water and create hydrogen for the future automobiles that use this in one form or another. Or the hydrogen can be piped in existing natural gas pipelines to power distant communities.

Now hold onto your hats again because all that I have told you is not nearly as far as we could go with this. I am only one person and I have sort of held onto and developed these ideas for some time with some sort of mistaken idea that I myself was going to create all this on my own. I suddenly realized - not too long ago - that if I really was serious about creating a power evolution (a developing into a higher form or state) I needed to share my ideas with others or inspire people with my same passion. If we could expend even a fraction of the time and effort spent on the space program or other efforts such as the creation of the nuclear bomb we would have this done in no time. Our energy production and usage would be totally transformed.

And so I challenge all of you alternative energy buffs and financiers to not only test and perfect what I have laid out here but to go way way beyond this coming together as a group and pooling and correlating ideas and technologies. We cannot rely on government funds on this as they do not have the same priority direction. We can after having created something on the order of a power grid that is not only more environmental but is producing electricity for around five cents per kilowatt hour, ask for funds then for infrastructure. But I feel most of the research money must come from us as a group so that every bit of it is used efficiently and effectively. I feel what is possible is a plant such as this taking up about 500 to 1000 acres and producing about 10 gigawatts of power.

So let's just do it.

A New Solution to Building Solar Panels Around Anything

2011-08-23T08:41:00.001+03:00

Recently conducted research in a lab has found a new way that we can incorporate solar cells. Basically the technology put in simple terms is "stretchable solar cells". Unbelievable? Yes it is, but it's possible. The creator likes to call it the "super skin". Besides being stretchable they are flexible too. They can be stretched up to 30% beyond their normal length.

Uses for the flexible solar cells
"One of the applications where stretchable solar cells would be useful is in fabrics for uniforms and other clothes," says one of the students. And quite a lot of other uses too. If you think about it, some vehicles would be able to adapt this flexible, stretchable material around the body. Or homes could use them around different locations of their homes not just the roofs.

We've already seen car companies use similar technology on the roofs of vehicles to power air-conditioning and other uses. The question is really what else can we use this technology for.
The greatest benefit with this new tech is that more people can get creative about how to make solar panels from their homes. No longer do they just have to make roof solar panels, but they can incorporate it around their entire homes and all sorts of portable devices to do the fact that this could also mean lighter solar cells.

It's going to be interesting to see what people make from using the super skin technology with solar panels. I think we haven't really seen a tip of what the future holds. Not only is this useful for people who make PV panels, but very interesting as well.

How will you use this new solar technology?
The future will bring much better technology as you can see, and all of it will get cheaper as it usually does, because demand grows and all the other factors of the economy. But we need to take action and begin to use the power of the sun to create electricity in our homes. We need to stop paying for it and start making it.

There is no excuse for not doing it. Nowadays you can go online and find solar cells for less than $50 and build a 60 watt panel for the price of two full tanks of gas. It's just a decision you need to make on your own. What are you going to do? Will you join the solar energy bandwagon and start saving money and the environment or will you keep paying extra for what you can get for free?

Learn how to make a solar panel before you decide to do it without any help. At solar panel lessons you'll get the necessary information to start a project from your home.

Solar Energy History-Present-Future

2011-08-01T16:57:00.004+03:00

The genesis of solar energy history goes way back to the year 1838 to an observer by the name of Edmund Becquerel who at that time had published findings on the capability of materials to change light into raw energy. Although it was fascinating at that time no one took the opportunity to pursue it then.

As time would have it, the first patent design for a motor running on solar energy was done by a man called Augustin Mouchot in 1860. Fortunately for him the monarch of France funded his project which gave him the ability to create a device that would turn solar energy into the first steam engine. This however was the beginning of things to come, for August went on to illustrate that the sun's rays can be used to make ice by connecting the steam engine to a refrigerator device. A medal was awarded to him for his discovery.

Notwithstanding, his one of a kind research was shortly becoming a financial burden for the French, who in turn seek out a cheaper arrangement with the English for a supply of coal. August worked assiduously, trying to come up with alternatives but there was no interest in such a commodity any longer for the French monarch. So the funding of the researches came to a halt!

Experimentation

Solar Energy Experimentation

The first book which was written on solar energy was by a man called William Adams in 1876. The book was titled "A Substitute for Fuel in Tropical Countries." William had conducted a number of experiments along with his student Richard Day using mirrors; they were able to create a 2.5 horsepower steam engine which was much bigger than Augustin's horsepower steam engine, whose power was just 0.5. Their design became known as the (Power Tower Concept) and is still a part of today's world.

In 1883, Charles Fritz was able to convert the sun's ray into electricity. The solar cell converted at 2% max which became a great turning point in solar energy history.
It was a Frenchman (Charles Teller) at the time of 1885 that experimented with a non-concentrating and non-reflecting solar motor. Charles became the first person to install a solar energy system onto his roof for heating water for domestic use; no one was able to achieve it before 1885. But Charles himself had a passion for refrigeration. As a matter of fact, he was deemed the father of the particular trade. Nevertheless, his desire to pursue his dreams into refrigeration caused a lack of interest towards solar energy researches and experiments, and of course the whole solar energy thing became dormant. Who knows what our present state would have been if he had only persevered.

The first Solar Company was by John Erickson, a Swedish inventor and researcher, who also had a part to play in the development of the solar energy, created a solar power steam engine that carried similar features as Augustin's design between the years of 1868-1888. John was the one that coined these words: - "A couple of thousand years dropped in the ocean of time will completely exhaust the coal fields of Europe, unless, in the meantime, the heat of the sun is employed."

Solar Energy -Industrialization

By the time of the birthing and the dawn of the twentieth century, solar energy was no longer operated as one man experimentation, but it rather became industrialized. In 1892 Aubrey Eneas formed the very first Solar Energy Company -"The Solar Motor Co." all the way through to 1905. The company kicked off with its mission by selling the world's first consumer solar energy system to one Dr. A. J. Chandler for an astonishing figure of $2,160.00. The unit did not last a week before disaster struck and it was destroyed in a windstorm. The second unit that was sold also got destroyed in a hailstorm shortly after. These streams of events led to the company's demise causing their doors to close forever.

Largest Solar Energy System Henry Willsie also took a shot at it by building two huge solar plants in the California state. Henry manages to be the first to operate power at night after storing it in the day. His company was successful in getting the logistics up and running but, it did not succeed in the area of marketing its units to the public and eventually had to close its doors permanently in 1904.
Sun Power Co. constructed the biggest and most cost-effective solar energy system covering 10,000 square feet. Though it was able to produce an enormous amount of steam it was unable to provide sufficient pressure. The merging of Frank Sherman and E.P. Haynes in 1906 gave birth to Sun Power Co ltd. They went on to build an irrigation plant on the outskirt of Cairo that suffered an unfortunate end through the Great War in 1914.

Solar Power - Advancements
The 1950s - the 1960s we saw a couple of advancement towards the development of the solar energy starting with the boys at Bell Laboratories, who accidentally discovered the use of silicon that evidently led them to put together a solar panel, that gave a rate of 6%. The commercial solar cell which was the first of its kind was made available to the public in 1956 at a cost of $300 per wattage. Space programs also got involved using solar technologies. The first satellite to used solar energy to generate electricity was in 1958.

Energy Crisis We recalls the energy crisis in 1970 (OPEC oil embargo). It was not until then, that those who were in authority realized how dependable our existence was on non-renewable resources, such as coal, oil and gas that they relentlessly seek alternative forms of energy. The price of solar cells had drop to an all-time low of $20.00 per wattage.

Solar Energy Failures and Lasting Potentials
The company that were producing 95% of the world's largest amount of solar electricity in the 1980s to 1991, was situated in Los Angele and had to close their doors permanently. This closure was due to the withdrawal of their investors who became frustrated and withdrew from the project because the declining of the non- renewable fossil fuels was irreversible, while governmental incentives also, were not promising. These were the words of the chairman of the board of directors: "The failure of the world's largest solar electric company was not due to technological or business judgment failures but rather to failures of government regulatory bodies to recognize the economic and environmental benefits of solar thermal generating plants."

The Earth's Future It was calculated that solar energy that is absorbed by the Earth's atmosphere through the ocean and land masses is approx. 3,850,000 (EJ) per year. In the year 2002 generated more energy in one hour than the world used in one year. There were approx. 3,000 EJ per year in biomass which photosynthesis captures.

Having the revelation of solar energy history, has informed us as to how we may go forward as a generation seeking a greener earth. The quantum of solar energy that hits the earth's surface is so vast that in one year it is about twice the amount that will ever be absorb from all of the earth's non-renewable resources of coal, oil, natural gas and uranium all together.

Hi, my name is Jeroam Des Vignes and I am very passionate about our earth's condition. I will like to use this medium to educate and sensitize people on the subject of solar energy history. If you are someone with similar passion for our environment then I strongly recommend you go to this site immediately.

The Future of the Motor Boat Is in the Solar Panels Boat!

2011-07-28T00:02:00.004+03:00

New panels could be laid out flat on any surface whether it is a rooftop or ground. These panels have also found their place on our boats hence we have a solar panel boat that derives its energy from sun.

For centuries, we have been using wind power and muscle power to drive boats along waterways. At that time, the boats were just a wooden mass built to carry goods and passengers. Invention of the motor engine that runs on fossil fuel changed the way boats were driven. The boats were fitted with large engines that could run the boat even on rough waters and carry more goods and passengers. Today boats run on electric engines and require a considerable amount of energy. The traditional engines are no longer beneficial and we want a new engine that is light weight, fuel efficient and is as powerful as the motor engine. The answer lies in solar energy and boat we are looking for is solar panels boat.

Solar power is a stable source of energy that is never going to cease at least not within the next ten thousand years. Solar panel converts sun rays into electricity that could be used the way we want.

Earlier solar panels were big and bulky but the latest ones are better designed. New panels could be laid out flat on any surface whether it is a rooftop or ground. These panels have also found their place on our boats hence we have a solar panel boat that derives its energy from sun.

800 Watt solar system on boat

Being waterproof, these solar energy products are just perfect to use on the boat. No matter how saline the water is, it has no effect on these products. Because these panels are amorphous solid, we can rely on their durability. The sun and water can do more for you while you are out on the deep blue water. With these solar energy products on your boat, there are literally no worries about you running out of fuel or the motor engine stopping in mid-way.

Flexible and portable solar panels can be carried and used practically on boats. These are light weight, occupy less space and use only sun rays that are available in plenty. A boat equipped with these solver energy products s fuel saving, hence you save on money. It is light weight because you don't carry fuel tanks and extra fuel for midway filling. Solar panels can be set on the rooftop of the boat and in this way a lot of space could be created on the deck or in the boat for keeping more goods. These solar energy products have made our dream true. Now we can sail anywhere without fearing of fuel consumption or motor breakage.

Solar Power Motor Vehicles For The Future

2011-07-26T18:03:00.001+03:00

You can now get a considerable variety of machines, appliances, gizmos and gadgets operated by solar energy. There's also numerous residences, houses, industrial facilities and businesses powered by alternative energy sources. Solar powered cars have also risen in popularity as men and women became more aware of the numerous positive aspects of the renewable energy resource. It is possible to save thousands of dollars in petrol costs every month by selecting a solar powered vehicle. You have to understand the different available benefits and alternatives first. Here are several more details about how you can get the very best type.
The Solar Method

For some regions of the world, the totally solar powered car might not be possible, because of the lack of sunlight. For other regions of the world it may possibly be the only choice available.
A solar vehicle is identified as an electric vehicle that's powered only by solar energy. The power is gained through solar panels on the outside or the top of the vehicle. PV or photovoltaic cells change the energy of the sun directly into electrical power. Solar vehicles are not utilized as everyday transportation devices presently. These are generally still utilised in engineering tests and exhibition practices, usually backed by private or government agencies.

Solar cars usually merge the different technology found in bicycle, aerospace, automotive and renewable power companies. The design of the solar vehicle is limited by the energy level placed into the auto. Virtually all solar cars were created with the objective of solar car races. They're now increasingly being developed and made for day-to-day use. Solar cars are normally equipped with the gauges comparable to standard cars. The driver has to watch the gauges closely to see potential issues and keep the vehicle operating smoothly.

Solar cars make use of PV cells to transform sunshine into electricity. 51% of sunlight actually enters the earths atmosphere. Unlike solar thermal energy which transforms solar energy to heat for business or household purposes, PV cells can directly change sunlight into electrical power.
Gathering Solar Power

The solar array is produced of many photovoltaic solar cells that convert sunlight into electricity. To create an array, the PV cells need to be bundled together to build modules which are placed together to make an array. The bigger arrays can create more than 2 kilowatts or 2.6 hp of power.

This photovoltaic array may be fitted in a variety of ways. Just a few ideas are horizontal arrays can be fitted in the form of a canopy. Vertical arrays could be installed in the form of incorporated or free standing sails to also have the advantages of wind power. Flexible solar arrays can be tilted around the travel axis to improve energy once the sun is low and to the side. Integrated arrays could cover the whole surface of the vehicle with solar cells. Remote arrays could be completed by creating photo voltaic arrays at various intervals along the side of the road. The trailer array might be accomplished by retro-fitting current vehicles, however there would certainly also be the problem of balance with this thought.

Put Into Practice
The first industrial electro-solar hybrid car, called the Venturi Astrolab has been around since 2006. Some companies in May 2007 also made changes to a Toyota Prius to work with solar cells to produce up to 240 watts of electrical power in the sunshine. Golf buggies are shown to have very practical uses if operated by solar power. The Solartaxi was also recently unveiled. And a solar powered car has traveled around the world, or 50000 kilometers in just eighteen months.

Home Panel Solar Politics

2011-07-26T00:55:00.001+03:00

After recently reading a New York Times article, we started thinking about home panel solar politics. You see, although solar power is gaining popularity as a renewable energy solution for home, it will never become mainstream without the backing from the federal government.
A poll by the Nuclear Power Industry revealed that the number one choice for generating power was not from nuclear, coal or natural gas, but from solar energy. However, at the time the poll was taken solar only provided for about 0.01 percent of America's power supply. Solar power is popular, but there's not enough investment!

In Washington, where the energy policies are signed, solar power lobbyists generally work with small budgets in the tens of thousands of dollars. Now when you compare it to the tens of millions of dollars that nuclear, coal, gas and oil lobbyists have available, you can only guess which energy policies gain approval by our beloved politicians.

But when you look at countries like Germany and Japan, their government policies have increased solar power implementation beyond what was thought possible. With the support from government not only have the manufacturing costs decreased because of economies of scale, but solar technologies have also rapidly advanced.

We know government regulation is not very popular in America, where many of us believe our capitalists markets should be left alone. But according to Vinod Khosla, a partner at one of the world's biggest venture capitalist firms - VC Firm and major investor in green technologies:
"...Market-driven improvements are not happening fast enough to put solar technology beyond much more than a boutique investment".

We agree with Mr Khosla. Until the American solar industry gets backing from the federal government, our solar power costs and technology will always lag behind the rest of the world. And as long as that happens, solar power will never gain mass-market appeal in the US.
However, with the new change of government there are 3 distinct factors taking place that give us assurance that home panel solar power is about to take off in America.

1 - The new president-elect Obama and his administration is putting big coal and oil aside, and giving green technologies higher priority. Furthermore, their new laws will help limit the power and influence wealthy lobbyists have on new energy policies.

2 - Some states, such as California and Hawaii are not waiting for Washington to pass the new energy policies. Instead they are taking initiative. Governor Schwarzenegger's "Million Roof" campaign will not only create a new industry, but also lower global warming and create thousands of jobs.

3 - And lastly, we, the home panel solar power users have the biggest role to play. All the energy policies and campaigns would be useless if the population did not embrace solar power at home. But, from the poll and what was said by Mr Khosla, that is not a problem. The America people are not only very interested in solar power, but are also supporting it with investment.

And although it can take years to pay off the solar power cost, people still invest. And when cost is a concern some are so interested in getting involved that they learn to make and install their own home panel solar power. So, let us continue moving towards solar and supporting the politicians and corporations who promote green technologies.

Solar Energy Costs and Economic Impact

2011-07-23T01:26:00.002+03:00

According to a global price survey, solar energy prices have declined an average of 4% per year for the past 10 to 15 years. There is a progressive increase in conversion efficiencies of cells, and manufacturing economies of scale are the underlying drivers of this price decrease. The Solarbuzz Global Price survey clearly indicates that prices have consistently declined for over the last two years.

A detailed analysis of the worldwide photovoltaic market is present in on the the leading industry reports, the Market Buzz 2009. A residential solar energy system typically costs about $8-10 per Watt in 2009. When government incentive programs exist, and coupled with with lower prices secured through volume purchases, installed costs for solar panels can become as low as $3-4 watt - or some 10-12 cents per kilowatt hour can be achieved. Without incentive programs, solar energy costs range between 22-40 cents/kWh for very large PV systems.

Another system being used for large power stations is the concentrating solar power (CSP) technology, this is a large array of mirrors or lenses that are focused to either produce heat, or directed towards PV systems. These are built at a cost of $2-$4 per Watt. Some estimate that these types of solar arrays can produce 25% of the world's energy needs by 2050. It is expected that the cost of CSP can become as low as 6-7 cents per kwH, as low as conventional energy production. The CSP industry is growing quickly in Spain and the United States, and the SEPA is tracking over 5,000 MW of new project announcements that are slated for development until 2015. Not all of them will be built; permitting, financing, technology and other factors need to fall into place first but the industry is poised for rapid growth regardless of any individual project's outcome.

A Solar-Powered Renaissance for Allentown, PA

Solar energy already has a tremendous effect on the world economy. Domestically, the US market for PV is expected to be around $27 billion dollars by 2020 according to the Department of Energy, and directly and indirectly create 150,000 new jobs. Practically speaking, solar energy also allows countries without a grid infrastructure to power isolated areas, and individuals to power their own home independently, constantly receiving a free source of energy from the sun. Even in the U.S., distributed transmission lines and independence of energy sources is becoming more critical due to aging infrastructure and local emission restrictions. As an example of energy independence, Hawaii's Mauna Lani Bay Hotel's installed PV cells on its large rooftop. These generate 75 kW of energy and this solar panel array is expected to pay itself off in 5 years.

Solar power is not subject to political risk, and it is impossible for it to be blocked. Solar panels can also be placed on non-arable land, such as that present in New Mexico, the California Desert, and Arizona. This can also be considered in other countries, like Pakistan, India, China, and even the Saharan Desert in Africa. It is calculated (from a Rice University whitepaper) that it would take 25000 square kilometers of solar panels to produce all of the U.S. Electricity needs for one year, and there is definitely this amount of land available in the United States. In fact, more land is being used to grow ethanol currently. I expect that within 30 years, solar power will become the dominant energy source in much of the developing world and the United States.

Why the World Still Uses Coal, Oil and Natural Gas

2011-07-22T12:21:00.002+03:00

Coal, oil, and natural gas are still dominant sources of energy despite the fact that renewable energy is getting more and more supporters. Wind power and solar power are becoming increasingly popular but coal, oil and natural gas have founded our economies and industries meaning they still have very strong political support.

Fossil fuels have more than just history on their side, what they also have is advantage in costs. Renewable energy is sadly still significantly expensive option compared to fossil fuels, and lower costs are really the key component that gives fossil fuels an edge.

Renewable energy technologies are constantly developing, and their development is dropping prices so they are getting near the prices of fossil fuels (especially wind power that is currently the cheapest renewable energy option). However getting near doesn't seem to be enough, and coal is thus still the most dominant energy source in the world, and world's greatest source of electricity.
In about 150 years time fossil fuels would likely be depleted, and world will have to have a decent replacement ready. From the current point of view using renewables looks like the only option capable to replace coal, oil, and natural gas but this is far future from where we are looking today.

We must not forget that fossil fuel burning does great damage to our planet in form of global warming phenomenon, and if the current scientific prediction about future climate are right we definitely do not have 150 years at our disposal to make the energy switch towards using more renewables. We really need to act much sooner.

Ned Hall firmly believes that one day wind and solar power will become dominant energy sources and in order to make that happen renewable energy sources need more promotion. In order to do so he has written many interesting solar energy articles as well as many other interesting wind energy articles

Solar Panels by Night

2011-07-20T23:18:00.001+03:00

How to bank on solar panels at night
Making the most of the solar radiation that reaches our atmosphere is the need of the hour. Sadly, the rate at which we are using this non-exhaustible source of energy in the form of solar panels is very slow and without regard for the huge savings that can be invited upon our homes, offices and lifestyles.

Sourcing energy by day and night
Our fossil fuels are bound to get exhausted sooner or later. The consequence is that the depleting quantities have raised prices and made the availability of fuel a luxury! Not only is the energy from the sun trapped by the solar panels cost efficient but also green, safe and completely dependable. Solar energy is without a doubt the best replacement we have for fuel on our planet. In the near future harnessing and reusing solar power by night is going to be the clarion call of governments and environmentalists.

So, how is solar power sourced at night? Well, it is imperative to understand that solar power is derived out of the heat and light of the sun. Solar panels help to capitalize on this important component and the star of our galaxy. Solar power generation can even work to light up your home at night. The very basics of solar energy tell us that the light and heat that reaches the surface of our planet during the day is trapped within the atmosphere and then bounces off the surface at night. With the help of the solar panels it is now possible to capture the sunlight and heat and convert it to electrical energy. This need not be used immediately. It is stored in special cells or batteries and then routed and distributed as and when required.

The panels are designed to absorb the radiated heat and store the direct sunlight for later consumption. Solar panels comprise photovoltaic cells, made from semiconductors. It is common to find silicon in the photovoltaic cells which frees the electrons and leave them routed to the positive connection within the design. This is then positively charged by boron and the result is electrical current! The energy thus produced by the sun during the hours of the daylight can be used for electricity generation by night.

What happens is that the trapped current is converted into a voltage in the solar cell. The formed direct current or DC is then stored in a battery within an inverter. Though the process requires sunlight, the energy saved in the form of electricity can be used at night. The use of solar power to light up your house calls for a basic education on the working and efficiency of solar panels at night and during winter. Although these times are when less amount of or no sunlight reaches the panels, the stored energy is pulled into action. Conservation of solar energy even allows you to strike a deal with the local utility grid or special outlets called battery banks. They in turn pay you for sourcing the stored energy or electricity you have at hand!

Oil Companies Using Solar - The Ultimate Irony

2011-07-18T17:41:00.000+03:00

GlassPoint is Using Solar Power to Draw Oil From the Earth

The energy debate is often categorized as the fossil fuel companies versus the clean energy companies. While there was certainly a major battle early on, the line has become much less clear these days. This is particularly true when you consider the fact that many oil companies now incorporate solar energy as part of the energy production for their facilities. Yes, it is the ultimate irony.

Oil is often hammered as being the ultimate evil these days. Well, it isn't. The room you are sitting in and the computer you are reading this on are all made possible by oil. In fact, our society never would have advanced to this level without it. Oil is not just in your car and gasoline. It is the base material of plastics and just about every critical material we use to make things. The problem, of course, is oil is a toxic pollutant. This is particularly true when burned, but it can cause messes in its natural form as we see in the BP gulf mess. This means a move to cleaner fuel sources just makes sense.

The idea that oil companies are battling green companies is true on one hand, but the conflict is coming to an end. How do we know? Well, we have to look at an old cliche' - if you can't beat them, join them. This is exactly what we see happening. BP may be causing environmental disasters in the gulf with its oil operation, but it also is one of the first major oil companies to launch a solar energy company known as BP Solar. It is not the only company doing this.

Chevron is pretty much the prototypical major oil company that comes to mind when discussing such companies. It hardly has a stellar environmental record as the litigation regarding the huge toxic waste mess in Ecuador shows. Still, even Chevron is coming around to the renewable energy idea. It has announced it is launching no less than seven different solar energy projects to research technology and get into the field. The irony of this is they are building some of the projects at old refineries and using the electricity produced to fuel the oil production complex they have for the Chevron Kern River oil fields. Yes, solar panels will power oil production.

Solar Power Technology Is Being Developed For Enhanced Oil Recovery

The relationship between oil and green energy is one that is blurring all the time. Generally, this should be viewed as a positive development as it moves renewable energy from the "alternative" energy classification to part of the basic energy production pie we have in this country and world wide.

Can Solar Power Replace Oil Consumption?

2011-07-17T15:06:00.003+03:00

Big Oil Vs. Solar Power - Your Choice - More free videos are here

The energy debate often involves people taking such passionate positions that they talk past each other and really miss some rather obvious facts. This is very much the case when it comes to the debate of whether solar power can replace oil consumption in our modern society.

The oil versus solar power debate is mostly a red herring argument. The primary problem is these two energy platforms are, for the most part, in different areas of the energy argument. Put another way, we are talking about an apples and oranges argument. Let's take a closer look.
Solar power primarily provides two types of energy. The first is electricity and the second is water heating. Solar panel systems are used to generate either of these forms of energy. There are larger commercial scale power plants based on solar energy, but they are few and far between.

Most people don't realize how many different ways oil is used in modern society. It is a part of the chemical composition of pesticides, plastics, roads and so on. As a burnable energy source, it is primarily refined to create fuel for vehicles. These range from your average family car to jumbo jets flying around the world.

The problem with the solar versus oil argument should be obvious. Solar will never replace gasoline and gasoline is not used as a fuel source to generate electricity in all but a few power plants. Coal is by far the most common fuel used to generate electricity. Solar might replace it one day, but that is an entirely different argument.
Okay, what about solar cars? They are a nice idea, but we currently do not have the technology to make them happen nor will we for decades into the future. The modern solar panel is simply not up to the task nor is current battery technology.

The next time you hear the solar power versus oil heat up, you might want to mention the inherent problem with the debate. Then again, maybe not!

Comparing and Contrasting Oil and Solar Power As Energy Sources

2011-07-15T10:43:00.002+03:00

Definitely, solar power and oil based fuels have a common purpose; to power technology. Even though they both appear to offer us energy to power the world they do have great differences in them that separates them completely. More than just using them to power our everyday activities, we should know their characteristics to gain a better choice.

Price. Oil based products came from the dead plants and animals long before we've had invented electronics and cars. And from a base product, it is converted into many forms we have now like gasoline and diesel. But these process, from pumping out from the ground to the refineries, it would take a lot of manpower and machinery thus resulting to a high and fluctuating price we have now. Solar power is quite different, it literally comes from nature. This energy has been here ever since the sun came to exist, fact is fossil fuels got their energy from the sun. This sun's energy is available to anyone and it's free.

Availability. It is a vital part for an energy source to have an ample amount of supply to cater the growing need. By this it should be handling the demand with ease. Oil based products, though may have appeared to cater the whole world, does not really have an everlasting supply. The present supply is limited and in order to replenish it, it would require years, thousands of years. Solar power on the other hand is given off by the sun everyday without having to wait for years to replenish it. That would result to an economic stability for developing countries.

Transportation. Oil based energy may not be sourced all over the world, there's just several countries which do have the proven reserve for it. And other countries which also use these products would have to wait for weeks, if not months, in order to get hold of it. Though the supply all over the world is being replenished continually, it is inevitable that some unfortunate things could happen like accidents. This could cause shortage on the supply which can cripple economy. But when a country would consider, even on the very least percentage, solar power chances like these is at minimum. This could make nations prosper even the supply for oil based fuels would be altered.

Environmental concern. It is a fact that oil based product emits harmful fumes and other by products. Even when used in small amounts, it can still produce emissions which can cause a lot of trouble for our environment. This one side of using oil based products that we cannot ignore these days. Good thing more and more people have joined in changing their ways in sourcing their energy supply. Alternative energy like solar power never emits emissions so you can be sure that you'll be using clean and safe energy source.

Progress should never be the reason to sacrifice our environment. With technological advancement we have, we should take part and use it to balance our needs. Changing our ways is never too late. Changing for the better, with a better energy source, is best dealt with alternative energy like solar power.

Build stronger tomorrow, use alternative power source.

Cheap Solar Energy at Home With Help From the Government

2011-07-14T09:40:00.005+03:00

President Obama Visits Green Energy Start-Up Solyndra

Solar and renewable power projects have become so popular over the last few years that some state and federal governments now run programs that offer economic incentives to invest in solar energy projects. This is yet another reason to consider solar for the home.

Quite apart from the economic considerations, who wants to continue to invest in methods which involve the United States paying billions of dollars to foreign governments, many of whom are unfriendly or passive at best, in return for fuel....

A federal energy bill offers tax rebates for solar energy projects undertaken by the homeowner. Renewable energy incentives were recently included in the government's $700b "bailout" bill, much to the relief and joy of environmentalists and the renewable energy industry itself. It seems that the new Obama administration is keen to jump on the green bandwagon too. Recent comments from the president-elect should provide additional incentive for the homeowner to invest, as Mr Obama intends to invest 150B in green energy programs and projects, creating five million jobs in the next decade.

Far from being either too expensive or too difficult for a typical homeowner to undertake, solar power production in the home is a very reasonable and realistic proposition. The materials necessary for this project are readily available and, when completed and installed, solar energy can produce the majority of a home owner's needs for domestic purposes - heating, cooling, lighting and so on.

Many Americans are taking advantage of the current economic environment and consulting with their tax advisors to consider a home solar power project - it makes sense all around.
Solar power at home makes sense on so many fronts and it does not have to be either expensive or very time consuming. More information is available here - Solar Power Home Now [http://www.solarpowerhomenow.com/]

Decorative Solar Garden Lights - 3 Tips For Selecting the Right Light

2011-07-12T12:58:00.001+03:00

Considering decorative solar garden lights to illuminate your landscape? There are many things to decide before purchasing your new lights. These few tips can help.
Placement - More than Just Decoration
You probably already have a place in mind if you are considering getting solar garden lights. Take another look at your location. Is there enough sunlight during the day to charge your solar lights? Is there sufficient drainage to prevent water condensation and damage? How much light do you want to add to the location at night?
Most decorative solar garden lights only add accent lighting to the landscape. They are not intended to provide safety lighting. If the reason you want to add lighting is to be able to see different features in the landscape at night, decorative solar garden lights might not be your best option. These lights also require plenty of sunlight during the day to recharge the batteries for night. If the location is shady, the lights won't illuminate as long and the lifespan of the batteries are reduced. Also, if the area gets too much moisture, water can condensate in the light and reduce the quality.
Decorative solar garden lights are water resistant to withstand rain and sprinkler systems, but the location should provide enough drainage so that water doesn't have the opportunity to seep inside. Remember, they are water resistant not water proof. Once these location issues are resolved, then you are ready to look at the wide variety of decorative solar garden lights available to suit your needs.

How Many Solar Lights Do I Need?
Rule of thumb in landscaping is that alternative placement of plants and other features is more appealing and gives a more balanced look. For example, if you want your decorative solar lights to line a walkway from your driveway to your front porch, you will want to stagger or alternate the lights on each side, instead of placing them opposite of each other. This is more appealing to the eye. Also, space your solar lights evenly apart - about .5 to 1 foot apart. You can measure the area with this spacing suggestion to determine how many solar lights you will need. Most decorative solar lights are sold in sets of even numbers.
Many Types and Styles of Solar Lights
When solar lights first came to the market, there was little choice in style. Now, decorative solar garden lights come in a variety of shapes, sizes, and styles. Selecting a type and style of solar garden light largely depends on your taste and preference. Do you like an antique look? There are many retro-looking shapes and some come in antique copper colors. Do you want minimal notice of the lights during the day? There are decorative solar garden lights that are flush with the ground so they blend into the landscape. Do you want a classic look? There are still plenty of solar light choices to fit any decorative style and purpose.

For wider selection and choices, shop online to find the right decorative solar garden lights to suit your needs.

Solar Deck Lighting - Decorative and Fun

2011-07-11T22:36:00.005+03:00

Solar deck lighting is an energy efficient method of providing accent and safety for any outdoor deck location. These lights rely on energy derived from sunlight to charge batteries through miniature solar photo voltaic (PV) cells located on top the lights. This eliminates the need for installing unsightly electrical wires or cables around a deck. Also, these are ideal for existing decks to keep from disturbing the deck to install electrical wiring.
Solar lights can be used in a variety of situations and locations on a deck, for example:

Deck Lamp Posts
Deck Post Lights
Deck Spot Lights
Deck Bar Lights
Deck Steps
Pool Deck Lighting
Deck Lighting
Motion Sensor Deck Lighting
And More

Solar lights have the advantage easy installation anywhere they are needed. They can by just be
attached to the deck in any desired location. An important point to remember when placing these lights in the desired location is to ensure they receive direct sunlight on the PV cell for charging the batteries.

The disadvantage with these lights is that their tops must have direct sunlight to the solar PV cells to fully recharge their batteries, because this is where the PV cell is located. Indirect sunlight will charge the nickel cadmium (NiCad) batteries, however the charge will not last long. If the desired use for solar lights on decks which have trees or the home blocking direct sunlight, then traditional electrical outdoor lighting is required.

There is no cost to operate solar deck lighting. However one drawback for solar lights is that they do not produce enough light for security lighting or bright lights. They only produce enough light for someone to see steps and other features of a deck.
The rechargeable nickel cadmium (NiCad) batteries will produce enough power to light solar deck lights for approximately 14 hours when full charged. Typical light times actually run 10 to 12 hours and 5 to 6 hours in the winter.

Solar deck lighting works effectively anywhere; however it is important to remember these lights require direct sunlight all or most of the day. Indirect sunlight will charge the NiCad batteries, however the charge will not last long.

Another advantage of adding solar deck lighting for safety and accent is that it can increase the value of a home. Many people deciding to purchase a home will visit in the day and night time to get a feel for the neighborhood. When they see a beautifully accented deck with solar lighting, they are more inclined to purchase the home.

The Nanotechnology Solar Cell Revolution

2011-07-10T13:42:00.002+03:00

There is little debate that we need to wean ourselves off of fossil fuels, but the costs of renewable energy platforms such as solar make it difficult. Nanotechnology definitely offers the answer.
Solar power is considered one of the better renewable energy platforms. Enough sunlight hits our planet each day to meet our world wide energy needs for an entire year. On top of this, solar energy is a free power source, since nobody can corner the market on the sun. Solar power is also good for the environment since it produces none of the emissions that are of such concern today, specifically carbon dioxide greenhouse gases.
If solar is so great, why don't we see more practical applications? The problem lies in the applications. Specifically, we have no way to harness the power. Commercial solar cells are very inefficient. Current models on the market only convert about 8 to 13 percent of the sunlight hitting them. This inefficiency makes the cost of producing energy via solar platforms too costly. So, what can we do?

Nanotechnology is a new scientific field with many applications. Although the media has hyped the technology as the answer to a wide variety of miracle cures, most scientists and companies are looking to more practical applications. One such application is improving the efficiency in solar cells.
Nanotechnology has already shown huge breakthroughs in the solar field. In certain studies, the use of nano applications has improved the conversion rate of solar cells to an incredible 65 percent, a slight increase over the current 8 to 13 percent rate. Although none of the applications are currently refined enough to be turned into commercial products, they are getting close. Let's take a look at a one of the approaches.
Quantum dots have the potential to change the world. They are a form of solar cell that is completely beyond anything you might imagine. Traditional solar cells produce electricity in a unique way. When the sunlight hits material in the cell, the material kicks of an electron and the charge is the electricity. Quantum dots work the same way, but they produce three electrons for every photon of sunlight that hits the dots. The dots also catch more spectrums of the sunlight waves, thus increasing conversion efficiency to as high as 65 percent, a stunning figure.
The really interesting thing about quantum dots is they do not require big, bulk solar panels to work. Researchers are combing the dots with liquid polymers. In practical terms, this means they can be sprayed onto any surface. This literally means that anything painted can act as a solar cell. Think about that. In the near future, you will be able to go solar by just repainting your house. Hybrid cars will be revolutionized, so will your mobile phone. On a cold day, you can put on a coat and gloves that are heated by the solar cells imbedded in their surfaces. The scope of this breakthrough is as breathless as it is unlimited.
Let's face it. We need to make changes to the way we produce energy. It appears as though nanotechnology may convert solar power from an iffy solution to a definite one.

Solar Energy Trends

2011-07-08T08:44:00.000+03:00

According to a recent study, 80% of over a thousand American respondents think all new home construction from now on should include some sort of solar energy systems. Once informed of the higher resale value that homes with solar systems can have, 2/3 of those surveyed said they'd expect to pay more money for such a home, a would do so willingly; what's more, 1/2 of those surveyed said they'd even be willing to pay a 10% premium on for homes with solar energy systems built-in.

Solar Water Heaters: People living in warm climates and freezing climates alike can now enjoy the benefits of solar water heating. Though the technologies are slightly different depending on whether there's ever a freeze lasting longer than a night or two, solar hot water is a viable option wherever a person may reside.
Solar Shingles: By all appearances, these look like ordinary shingles, but look closer and you'll see that they're actually thin-film solar cells. The amorphous silicon material used in these shingles is reported to be even more effective at collecting sunlight than regular solar panels while still being strong enough to be used as a roofing material. They're installed in an overlapping pattern, just like regular shingles, thus providing the same level of weather protection. The wires run underneath a plywood roof deck that protects the house from the intense heat these solar shingles absorb, and the shingles are held in place by a glue-like EVA compound that is activated by heat.

Recreational Solar Kits: The average Joe and Jane consumer can purchase complete solar kits that come with everything one needs to get solar power up and running in their RV's, weekend/seasonal cabins, and boats.

Your typical solar kit will include:
o 1 or more photovoltaic modules (solar panels)
o Mount (such as a flush mount rack or a pole top fix rack)
o Charge controller
o Safety disonnect
o Fuses
o Fuse box and/or circuit breaker
o and in some cases, a storage battery
Solar/Stellar Battery: Russian scientists have developed a battery that captures solar energy itself without the need for an external panel or collector. A true 21st century innovation, it also collects energy from stars, regardless of meteorological conditions.
New Materials: We touched on it in the above section on solar shingles, but thin-film solar cells deserve a repeat mention in any article on current trends in solar polar. This new, silicon-based thin-film technology adheres heat pumps and solar cells onto other surfaces, whether wood, drywall, glass windows, plastic - imagine the possible applications! This technology will vastly increase solar energy's versatility and range of practical applications while vastly decreasing the associated costs. Other promising R&D efforts into newer and better materials for solar energy equipment includes solar cells made from titania nanotubes, natural dyes, lead and cadmium selenide nanocrysals, and everyday plastic.
21% of Venture Capital firms surveyed spent a combined total of $500 million on renewable energy start-ups, including many solar power companies. Nanosolar is a start-up company that uses materials based on nanotechnology to make solar systems more efficient. Energy Innovations is a company that uses mirrors that follow the sun installed on panels to collect solar power.
According to Clean Edge, a company that conducts independent research on clean technologies, reports that the market for solar energy has increased 55% from 2004 to 2005, and will further increase from an $11.2 billion industry to a $51.1 billion one come 2015. By 2015, the costs for grid electric power and solar power should be neck and neck.

Solar power can save you a lot of bucks and it really looks cool! Visit our Solar How To [http://solarpanel.biogreenlife.com/category/solar-panels-how-to] section for ideas to save money on your energy bills.

Companies That Manufacture Solar Panels: List Of Best 30

2011-07-07T22:47:00.001+03:00

With the increase in the alertness and responsiveness towards the problem of global warming, more and more property owners are trying to do their best for the environment. One of the steps they are taking to help protect the environment is to employ solar-powered technology to fulfill their energy requirements. With the increase in the demand of these panels, the industry of photovoltaic cells has increased as well.

Germany had one of the major 15 companies providing solar-powered panels out of the total of 20 companies at one point of time. However in the race of solar-powered panel manufacturing, the USA as well as Europe have also come in, in an attempt to take a piece of the market. China, whose labor is cheaper than most of these countries, is now head to head with USA and Europe in manufacturing cheap and affordable solar panels for global purchasers.

For people running on a low budget, they can easily go for those companies who offer a do-it-yourself solar panel kit. But for people with cash to spend, they can do their homework, and buy the best deal as suited to their requirements. These manufacturers guarantee more than 25 years of life of the solar panels they produce.

Some of the solar panel producers are listed below:

Solar Energy Rebates In Australia

2011-07-04T22:04:00.002+03:00

There are a number of solar energy rebates in Australia and you can literally save thousands of dollars when you know the way to integrate these into your life. There are rebates for many different renewable energy options such as on grid connected and off grid solar panels, solar hot water or solar pumping systems. If you qualify for one of the Australian Government's renewable energy rebates, subsidies or grants then you could save a lot of money on your energy expenditure.
Home solar power rebates
The Solar Credits rebate can save you thousands on a system if you meet the requirements. You can also make money from a rooftop solar array. The major rebate currently available is the national Solar Credits Program. The Solar Credits multiplier offers thousands of dollars in savings depending on the size and location of installation, and applies to new installations of small-scale renewable energy generators eligible under the scheme. Solar credits will apply to the first 1.5 kilowatts (kW) of capacity installed. Renewable Energy
Certificates accompany solar power equipment purchases and can be traded for cash. However please note that the multiplier credits will only apply to the first small-scale generation system installed at an address.
Off grid solar power rebates
This is for Australians living in a remote location. If you switch to renewable energy you can get the Solar Credits multiplier for the first 20kW of a solar panels system and potentially save thousands on your energy bill. On Thursday, June 24 2010, legislation was passed for Australia's enhanced Renewable Energy Target. As part of this legislation, there were greatly increased financial incentives available for people installing off grid solar power systems. The legislation states that "households and businesses installing systems on buildings more than a kilometer from the main grid or who have evidence that it would cost in excess of $30,000 to connect to mains power will be eligible to receive the Solar Credits multiplier for the first 20kW of their system installed".
Solar incentives for business
This scheme is designed for environmentally conscious Australian business owners. Current business incentives include huge tax breaks, RECs, feed in tariffs and major rebates under the solar credits program. The solar credits program provides substantial savings for businesses on grid connect solar power systems. Businesses can claim a tax deduction on a commercial solar power system installed on their business premises. Businesses can also save money by installing a solar hot water system or heat pump. This will help to not only slash the electricity bills but also the business greenhouse gas emissions.
Solar schools grants
The Solar schools grant called The National Solar School Program (NSSP) offers most single campus schools in Australia $50,000 grants and up to $100,000 for dual campuses. The Australian Government is also providing generous grants of up to $50,000 (excluding GST) for each school in Australia to install grid connected solar power, which is a great way to reduce the carbon footprint and save money. In the case of dual campuses, the grant may go up to $100,000 (excluding GST) and this grant is available until June 2015, under the National Solar School Program (NSSP). There is also additional funding available in some states under state programs, so it makes sense to look around for rebates.
Government solar hot water rebate
The Federal Government announced major solar hot water rebate changes on February 19, 2010 and there are now rebates of up to $1000 available to install solar hot water systems. There are also rebates of up to $600 for heat pumps installed to replace electric storage hot water systems in existing privately owned homes.

In Australia the government offers rebates for home owners that install solar energy for their homes. This includes the products I had installed from this solar panels Melbourne service.

Renewable Energy Barriers and UK Renewable Obligations Certificate (ROC)

2011-07-02T23:17:00.002+03:00

When environmental issues, long term supply and future economical aspects are taken into account, the design and implementation of a renewable energy commercial international system should be created and adhered to in order to solve world's energy problems and possibly, reducing some of the impacts related to climate change.

That means in order to be able to provide a stable supply of sustainable energy, protecting the environment, curbing CO2 emission and, in the case of energy crops being used as a source of energy, an actual reduction of CO2 in the atmosphere, barriers to the implementation of the above should be removed permanently, first.
Fortunately, these barriers can be dealt with successfully if and when international, national and local agreements 'implemented' by all parties. According to Johansson, et. al., 1993, there are many opportunities exist to overcome these difficulties.

- Financial constraints which limit greater deployment of renewable technologies. This barrier lies in the perceived risk associated with investing in renewable energy technologies, which is generally higher than competing in conventional technologies and the effects of this higher perceived risk on a technology's market.
- Many of the technologies are new on the capital markets and as such there is more risk than in using established technologies. The higher the perceived risk, the higher the required rate of return demanded on capital.
- The perceived length and difficulty of the permitting process is an additional determinant of risk.
- The high financing requirements of many renewable energy technologies often present additional cost-recovery risks, for which capital markets demand a premium

Possible Recommendations.
- Low interest loans or loan guarantees might serve to reduce perceived investor risk;
- Tax credits for renewable energy technology production through the early, high risk years of a project may provide another mechanism for renewable energy development.
- Regulatory cost recovery mechanisms (which today often favour low initial cost and fuel based technologies) can be modified to recognise life-cycle cost as a more appropriate determinant of cost effectiveness.
- Effective redistribution of government spending in research and development that directly reflects the potential of renewable energy technologies.
- Part of the local and national laws and regulations should be born out of international laws and regulations, directly and/or indirectly.
Renewable Obligation Certificate (ROC)
In the UK, the government has set up a Renewable Obligation Certificate (ROC) (Biomass Task Force, 2005) in relation to the use of energy. This certificate details:
a. 11% of electricity should be renewable by 2011;
b. 20p/l tax rebate for bio diesel;
c. Direct support for renewable energy;
d. 20% GHG reduction target by 2020;
e. Climate Change Levy/Carbon Trust;
f. Emissions Trading Scheme (2002);
g. Set-aside payments for non-food crop production.

According to Ofgem (Ofgem, 2009) 'A Renewables Obligation Certificate (ROC) is a green certificate issued to an accredited generator for eligible renewable electricity generated within the United Kingdom and supplied to customers within the United Kingdom by a licensed electricity supplier. One ROC is issued for each megawatt hour (MWh) of eligible renewable output generated'.
The ROC certificate became law in 2005 when the government issued the Renewable Obligation Order 2005. The ROC obliged the power generating providers a percentage of their electricity produced from renewable sources. According to previous governmental legislation as early as 2002, every year the percentage of electricity from renewable sources should be increased e.g. 2006 6%, 2007 7% and so on, reaching 11% by 2011.
Power generating companies who cannot provide proof (certificates) related to the above, can be fined. As a digital certificate, the renewable obligation certificate (ROC) holds information concerning the production of renewable electricity per unit.

The certificate can be traded as they are guaranteed by the government.
Climate Change Levy Exemption Certificate and Market/Role of CCS (Carbon Capture and Storage)
The summary of the LEC and CCS has been outlined in the following points:
1. The Fossil Fuel Levy, a dormant levy on the electricity bill: originally created to support the nuclear industry, it will be reintroduced to provide long term funding for zero-carbon technologies
2. In 2001, the government introduced a Climate Change Levy, a tax on energy used in the non-domestic sector, in order to encourage energy efficiency and reduce emissions of GHG. The levy was repaid to businesses in the form of lower N.I.
3. The 2003 report 'Towards a Non-Carbon Fuel Economy, Development and Demonstration' introduced carbon tax, a direct payment to the government based on the carbon content of the fuel being used. This was a replacement for the Climate Change Levy
4. Preference shown to the purchase of goods from countries that have taken demonstrable steps to reduce their greenhouse emissions
5. When it comes to biomass as a source of energy, the documents asked and discussed questions such as: UK leads in biomass technology: What are the benefits? Export opportunities
Before investment occurs, there is a need for a long term price signal, as well as regulations and ownership. How much energy is used just in crushing the biomass (in reference to Mills)? Operation problems, furnace, types and problems related to their short and long term usage. Fuel logistics: type of furnace and maximum load. Energy Crop and co-firing post 2009. Technology used for Biomass (co-firing);
6. Decommissioning of the UK's electricity generators fleet, which will reach 30% by 2020
7. Decommissioning of North Sea Oil/Gas
8. Plant assessments, laboratory and rig testing (for a particular application)

Inspiring the Nation - First the Moon, Now Cleaner Energy at an Affordable Price

2011-07-02T00:21:00.001+03:00

Fifty years ago, in 1962 President John F. Kennedy challenged the nation's greatest scientific and business leaders to "put a man on the moon by the end of the decade." We rose to the challenge and we hit that goal in the summer of 1969.
Fast-forward to the 21st century, and we are facing a new challenge: Reduce greenhouse gas emissions dramatically very soon, or face more extreme weather patterns and destructive, volatile weather events due to climate change.
And what better way to promote rapid advancement in technology than to throw down the gauntlet. Speak out loud an outrageous goal, and challenge everybody to rise to the occasion.
CLEANER ENERGY AT AFFORDABLE PRICES
That challenge has now been issued for clean energy! The U.S. Department of Energy wants to reduce the cost of solar energy systems by 75% by the end of the decade. DOE has created a collaborative program called the SunShot Initiative, and the goal is to kickstart the solar industry with laser-focused research and design so that a decade from now it is self-sustaining with no taxpayer subsidies necessary, with competitive market forces working to spur innovation, growth and investment in a sector driven by greater consumer demand: cleaner energy at affordable prices!

I recently took a plane from Harrisburg International Airport via Dulles in Washington, DC to New Orleans, LA. Our return flight routed us through Chicago, IL. And I had the gift of a hot air balloon ride over Lancaster County for my 50th birthday on June 9th. Do you know what I noticed? Not much solar up on those roofs -- but there are LOTS of roofs!
I would go so far as to say that, even though I saw a few solar arrays, we have virtually NONE right now, and this is a tremendous opportunity.
Cleaner, renewable energy not only reduces carbon emissions, but it creates good-paying jobs. It also reduces our reliance on foreign oil. And it is tapping a FREE resource that we don't have to drill for or do research to find; we just have to harness it.
Energy deregulation is spurring competition, which in turn is promoting innovations and improvement in the energy industry. And giving consumers and business owners the ability to choose their energy supplier is also creating a greater demand for cleaner energy.
CONSUMER DEMAND
To demonstrate how hungry consumers are for cleaner energy, look at the phenomenal growth of Viridian Energy, a socially responsible retail energy supplier that offers a cleaner energy at an affordable price. It far surpassed all its competitors who grew at an average of 58% from 2010 to 2011, by growing at a whopping 708%, simply by providing electricity that is at least 20% renewable, PLUS whatever is mandated by each state where they do business.
So, in Pennsylvania for example, the state mandate for Renewable Portfolio Standards is that 9.7% of suppliers energy must come from renewable sources in 2011-12, so Viridian's commitment for 100% of their customers is that they will provide cleaner energy that is minimally 29.7% from clean energy sources that are generated in our state or region. And they do without charging extra for it -- in fact, it is less expense over every rolling 12-month period than the dirtier energy being provided by your local utility company!
So, I hope we are up to the challenge -- I'm tired of record-breaking Tsunamis, hurricanes, tornados, earthquakes and floods.... and we'll all breathe better!

Different Types of Solar Energy - How Many Are There?

2011-06-28T10:06:00.000+03:00

There are different types of solar energy that are used today. You ask how many are there. According to recent studies, there are three basic types but we will break it down into five different categories. Below I have listed each type and will describe each as it relates to the different uses.

Photovoltaic Solar Power-Energy that is created by converting the suns rays into electrical energy is called photovoltaic. I am sure you have seen solar panels on houses or businesses before. These are the devices that convert the solar energy into usable electricity. In a simple form it can be used to power solar lighting, examples of this are traffic signs, yard lighting, or security applications.
Passive Solar Energy-Passive solar energy can best be described as using the sun's energy without the use of mechanical devices. One example could be the energy from the sun concentrating heat on a black painted block wall which in turn would warm your house. Another example could be how the sun would warm your house through windows facing south. Even the use of sky light boxes on a roof using the sun to light rooms during the day.
Active Solar Energy-We discussed earlier not using mechanical devices, active solar energy uses mechanical devices such as pumps, or moving shutters controlled my the angle of the sun. Pumps are used to circulate water in applications requiring the moving of the heated water. One residential use would be solar water heating for a swimming pool were the heated water is returned to the pool using a pump. Other examples would be solar water heating and solar space heating were water is pumped through coils of tubing to heat a room.
Solar Thermal Energy-Sometimes confused with active solar energy, solar thermal energy is the converting of energy into heat. Anything that uses the sun's energy to make heat could be classed as solar thermal energy or energy from the sun to produce heat.
Concentrating Solar Power-This type of energy is used mainly for large production of electricity, and not recommended for home owners. This is a larger scale operation where electricity might be sold to home owners through their utility supplier.

I have listed five types of solar energy above but the last two could fit into one of the three classes above them. Solar energy is becoming a vital resource for power and heat production in the world today. Solar systems are becoming more economical for home owners to help cut the high cost of energy.

How the Government Can Boost Investments to Renewable Energy Companies

2011-06-28T00:37:00.001+03:00

Country policy on tax exemptions, grants and aids are different depending on the capacity of the government. Renewable energy resources are considered as one of the major components for a sustainable future in order to continue and heighten economic as well as industrial activities in the country.
Government can invite investors internationally and locally. The country is represented by the government, specifically the president, wherever he goes. Of course, the government will showcase the best of what the country could offer. Another is that the government opens an international fair once a year. For this year, Korea is hosting an Environment technological fair in Incheon. It will showcase Korea's finest companies that offer environmental management, clean energy and waste and pest control. Truly, this environment technological fair will open local Korean renewable energy companies to the global market.
Allow the government to invest on your company's bright idea. Sustainable power could be the new driving force of the country's economy. The U.S. and China are currently taking the next big step towards alternative energy. They are planning on stimulating the economy towards clean energy. Government investments may guarantee a higher chance of stabilizing yourself as a renewable energy company. Maybe in a few years you would be able to stand on solid ground on your own.

Green energy is for sustainability and not luxury. China's endeavor to continue providing electricity for the world's most populous country has stated that providing clean energy for 1 billion people would increase its role in the global stage. Investing on with this perception in mind would strengthen China as a whole international commerce, preventing and combating pollution caused illness towards a more sustainable future. Imagine if 80% of the most populous countries would advocate renewable energy usage; it would dramatically decrease carbon emissions in the atmosphere. It goes the same even for countries all over Europe. They plan to boost the usage of sustainable energy by 10% by 2010 for the whole continent.
Government incentives boost company performance big time! China leaning towards renewable energy companies and the continuous progress is all thanks to government incentives. In 2005, a law is passed on China regarding fixed rate tariffs and carbon credits to alternative power companies. Renewable energy marketing is easier and faster with government help best part is, the government would do it for you for free. It is not always that the companies think of human welfare. Clean power companies could take advantage of this opportunity to carry out its mission at the same time make business. Government cash grants, tax credits and special promotions would allow technology development to increase competitiveness as a company. Renewable energy information via government would increase chances of being marketed to a wider audience.

Shirlyn Dee is a co-owner of Keen Partnerships, a pioneer renewable energy marketing company. Keen Partnerships acknowledge the fact that the renewable energy company start ups need due exposure, and has the resources and manpower to give quality Internet marketing services for renewable energy players.
She started as an SEO writer, but quickly progressed into making and deploying sites after learning basic SEO requirements. Now, her tools and techniques are both efficient and sophisticated, hence starting her own alternative energy marketing company. She has successfully deployed sites, and has been in the Internet Marketing industry since 2005, and is currently focusing on Keen Partnerships Renewable Energy Marketing Company.

It's the Economy - Energy Efficiency Gains Big Believers

2011-06-27T00:44:00.001+03:00

Bill Clinton said it best: "It's the economy, stupid."
The former president reiterated his economy comment in a piece in Newsweek, offering energy efficiency measures as several of 14 ways to jump start the U.S. economy and create jobs.
He's hardly the first. The corporate sector, utilities and governments are swapping out old lighting and inefficient energy-hungry systems like crazy. Why? It saves money.
This rapid embrace of energy efficiency over the past couple years has a lot to do with money. IBM says it's saved $50 million since 2008 through energy saving and conservation measures. "Bottom line; it pays dividends," the company said in a statement.
Converts are signing up in droves. Wal-Mart, an early believer in sustainability, played a big part in expanding the movement's reach. For instance, the retailer has provided more than 100,000 of its global suppliers with a sustainability survey and encourages them to embrace energy efficiency policies.
Utilities also are playing a major part, especially in California where representatives work one-on-one with clients to install retrofits and save money and kilowatt hours. While they are somewhat inspired by financial incentive, most of these reps have become some of the best educated on how to adopt energy-saving measures for the least amount of money.

Efficiency-aware utilities are hardly limited to the Sunshine State. On the north side of the continent, a couple of Yukon utilities launched an innovative program with Ottawa, Ontario-based One Change, a nonprofit that encourages people to adopt environmentally friendly behaviors, including energy efficiency.
One Change is helping the utilities get feedback from residents in far-flung places like Carmacks, Teslin and Dawson about what conservation measures they think will work in their communities, said Sara Haskill, the organization's marketing manager. Many of the communities in the program "are quite isolated and have limited resources. Yukon is also not hooked up to the North American grid."
But people who live in these harsh lands know better than most what works and what doesn't. When it's 50 below, a poorly insulated house requires three and four times what a super-insulated house needs in terms of heat. Northerners also tend to be quite careful (one mistake and you're a human Popsicle) and imaginative.
"We are definitely looking forward to hearing what the people in Yukon have to say," Haskill says. "We are expecting some innovative thoughts. Stay tuned to our web site/twitter/facebook in the coming months."
Who knows? The next big idea that creates 100,000 jobs might come from a Canadian in Old Crow.
In the meantime, here are some more traditional measures:
1. Lighting. Go with compact fluorescents, T8s or even T5s, using digital ballasts. Install occupancy sensors. Try LEDs. Their price is dropping. I bought my first bulb last week.
2. Insulation. Load up. HGTV's Mike Holmes tells his viewers to go overkill, R-40 in ceilings or more. Weatherize. I insulated my floor last winter. California home didn't have a thing. Reduces cooling costs, too.
3. HVAC. Yeah, it's expensive, but newer and more efficient air conditioning units or furnaces pay for themselves. Seal up existing duct work or add new stuff.
4. Electric motors. In this category, I'm thinking pumps and other items that draw a lot of power. Go with premium efficiency or variable frequency drive.
5. Roofs. Paint 'em white. Go with a cool roof if you can afford it. The savings payback works. Clinton offers up this one as well.
Speaking of Clinton, he's got a couple more in his Newsweek piece.
6. Copy the Empire State Building. The iconic structure is the epitome of energy efficiency these days after a costly makeover by its owners. The building now stands as a monument of how to successfully retrofit structures erected far before we came up with the concept of greenhouse gas or net-zero.
7. Utilities. Get them in on the energy efficiency retrofit action, Clinton says. "You wouldn't even need banks if states required the electric companies to let consumers finance this work through utility savings."
And diversify. A national trash hauler that pioneered landfill gas technology 20 years ago recently cranked up renewable energy generation power plants McMinnville, Ore. and Arlington, Wash.
"These projects show... increasing focus on green technologies that extract value from waste," said Paul Burns, a company official in Pacific Northwest, in a statement. It's efficient.
Analysts often advise clients to institute efficiency measures first. Then, they say, there's the option of adding renewable energy.
But I'll wait for the advice from the folks of the tiny town of Old Crow, via One Change. Last I checked on the web cam there was some work going on down from the John Tizya Center. The community is northeast of my old stomping grounds in Fairbanks, Alaska in the Yukon on the Peel River. People who live there are no doubt efficient, and tough.

Magnetic Energy Generator Cost Vs Solar Panels Cost

2011-06-26T00:23:00.001+03:00

Many people think only about solar panels as a way to generate an alternative source of energy and which can help them sever their dependence on power companies so that they can go "off grid". However, there are other alternatives to solar panels and using a magnetic energy generator is one of them. Magnets are capable of generating electricity as well and a magnetic energy generator is much more affordable than installing solar panels will be.
The Cost Of Solar Panels
Solar panels have been used for many years to convert solar radiation into electrical current. They generate electricity which can be stored in a collector, making it possible to power a home or building even when the sun is not shining.

Most studies have shown that you can expect to pay between $6 and $9 per watt of solar energy for a system that is installed for you. Overall, for a system that you have professionally installed you may spend between $30,000 and $40,000. This includes solar panels, an inverter box and the wiring which will carry your solar electricity through your home
. A system that you install yourself can still cost about $4.50 per watt of solar energy.
The panels themselves will vary in cost depending on how much energy you will want to generate. The best way to find out the cost will be to look at your energy bills and calculate the cost after looking online to find the exact cost of the panels you will be using.
If that seems like a huge investment, you may want to look at the cost of building and installing a magnetic energy generator.
The Cost Of Magnetic Generators

The cost of building a magnetic generator is generally much lower than that of a solar generator. Depending on the model and size of the unit you will construct, you may be able to build a generator for as little as $60- $100. This is quite a bit less than a solar system which you make yourself.
Unlike a do it yourself solar system, building a magnetic generator can be much more simple and often uses materials which you can find around your home or at any hardware store.
Other Advantages Of Magnetic Generators

There are other advantages to using magnets to generate electricity. Many solar panel systems take up a lot of room especially if you are using low-efficiency panels to keep the cost of your system as low as possible. You may find that if you are using broken solar panels that have been welded together as many people do that you end up with a massive panel that can take up a lot of room on your property.
A magnetic generator however actually takes up very little room. Because the magnets are all contained in a housing that is quite compact they can often be stored in a cupboard or closet if they are not being used continually.

A magnetic generator can also be located anywhere that is convenient. They do not depend on a steady supply of sunlight and can be fantastic for areas that do not have ideal weather conditions.
If you research both methods of generating electricity, you will find that a magnetic generator can help you create the power you need at an excellent cost.

Electric Car Conversion - How Much Does it Cost?

2011-06-25T00:42:00.000+03:00

Volvo C30 Electric Car 2011

How much does it cost to do an electric car conversion? Well, it used to cost anywhere from $5,000 to $10,000. But not anymore. New electric car technology has made it much cheaper. The conversion is also easier to do than it used to be. You no longer need to be a super-mechanic.
This is a great time to convert your gas-guzzler into an electric powered vehicle. The New York Times just reported that an electric car infrastructure covering the whole country is in the works right now. Not only that, but you'll be able to specify which source of energy you want. "Will you have wind, sun, or coal energy power your car battery, sir...?" It might sound crazy, but Forbes magazine says this scenario could become a reality in as little as two years!
But you can build your own electric car right now. There are many electric car conversion kits available online. They cost anywhere from $35 to $50. These sets of instructions are easy to download, so once you purchase one you're ready to start work immediately.

Next you'll need to find the right tools and parts. You can actually get a lot of the necessary equipment for free, or at very low cost. The manuals show you how. If you follow the directions closely, you'll be able to do the whole electric car conversion for as little as $300 (excluding the price of the manual).
When you're finished, your car will look the same. It will be able to go at speeds of 50 mph. You can travel 100 miles on just one charge. When your battery runs low you simply plug it in. Imagine never stopping at a gas station again! In addition, your car doesn't give off any pollution or make unpleasant noises. Electric cars are wonderfully quiet.
One of the best parts about driving an electric car is the huge rebates. That's right. State and federal governments will pay you to drive a renewable energy vehicle. When you add the rebates to all the money saved on gas, you begin to realize that electric car conversion isn't expensive at all. In fact, you'll come out ahead!
It can also be a lot of fun. And you'll learn about batteries. Big batteries that can hold lots of electricity are the next big industry. They're the cornerstone of clean-technology.
It seems pretty clear that gas-powered cars belong to the past. Electric cars are the next big thing. It's an amazing future, and by performing your own electric car conversion you can become part of it right now!

Solar Panel Questions - So Many Questions!

2011-06-20T21:11:00.000+03:00

We are always getting asked questions about how solar panels are actually integrated into the home to supplement your electricity usage or to replace your energy provider.
Here are a few typical questions and our answers.
Question: Why are commercially available panels so expensive?
There are lots of reasons but principally it's because the market is still quite small and there isn't yet a really competitive marketplace. Government solar rebates help reduce costs.
Question: How do I connect my panel into my home wiring?
Unfortunately it's not quite that simple. Never attempt to connect the solar panel into your home wiring yourself unless you are a currently registered electrician. The solar panel is part of a system consisting of a controller, batteries and an inverter.
You are generally allowed to wire up everything to the batteries but an electrician is needed for the rest.
Question: What do I need a controller, batteries and an inverter for?
A solar panel generates direct current not the alternating current used in your home. Further, the level of current generated varies in accordance with the amount of energy being converted by the photovoltaic cells in the panel. The controller regulates the power from the solar panel to the batteries so as to increase battery life or damage.
The batteries are the storage medium. You store energy during peak periods of sun light and consume the electricity from the batteries as you require 24 x 7.
The inverter is required to convert the direct current from the battery into alternating current at the correct voltage for use in your home.
Question: What does the controller really do?
The controller's job is to control the amount of energy going into your batteries so they don't over-charge or over-discharge. It's just like the voltage regulator in your car. As the battery approaches full charge, the controller slows down the rate of charge and significantly increases battery life. Without one you will need to manually watch the voltage on your batteries and connect and disconnect them from the solar panel manually.
Controllers are reasonably cheap to buy and there are plenty of DIY panel designs on the web. Just Google solar panel controller.
A basic controller simply monitors the battery voltage and opens the circuit and stops the charge when the battery voltage reaches a certain level. More complex controllers control the power applied to the batteries as the batteries get closer to full charge, so extending battery life. They can keep batteries in a fully charged state indefinitely.
The controller can also detect when no energy is coming from the solar panels and disconnect the panels to stop reverse current flow.
Question: Why do I need batteries?
Basically, they are the storage device to store energy from your solar panel until you actually need it. As the amount of energy converted by the solar panel varies during the day and night, the battery input charge varies. But the power stored in the battery is available to be used at any time, 24 x 7.
Question: Do I need special batteries?
Yes. Most solar panels require 12 or 24 volt batteries similar to what you find in cars.
You need batteries which can handle the deep cycle from fully charge to heavily discharge repeatedly over a short period of time. Car batteries are easily damaged if they discharge too deeply as they are designed to deliver a quick burst of power to start the engine. There are plenty of deep cycle batteries available on the market AND if your eligible for a solar power rebate, you may be able to include them as well.
Question: Why do I need an inverter?
Your home uses 110v (or 240v) alternating current. Remember this from your school days?
Appliances won't run off a battery as it is direct current. The inverter does the conversion for you.
Inverters are readily available on the web. Google solar panel inverter.
The inverter is powered by the battery as well but they are very efficient devices these days.
It is illegal for you to connect an inverter to you house wiring unless you are a currently registered electrician. And, your inverter must be an approved device so we don't recommend you make your own.
Question: Can I sell my excess electricity back to the electricity company?
The short answer is yes. The electricity company will change your power meter for a two way device which measures electricity being used by you as well as any electricity being sent to the grid.
But, we suggest you concentrate on reducing you consumption and saving yourself money that way.
There are some issues with selling back to the electricity company. They sell to you at retail prices but buy back at wholesale. So don't expect high prices. AND, the electricity you sell back must meet their standards which mean you may need special inverters and switchgear.

A Chinese Solar Future

2011-06-19T00:34:00.004+03:00

projects planned for China

The Olympic Games held in Beijing in 2008 highlighted to the world the problems that China is having with pollution in urban areas where population density and heavy road traffic has contributed to a situation where on some days visibility is severely reduced.
The televised images of the Beijing skyline obscured by a murky cloud of smog offered a grim reminder of the contamination which is of course an inevitable by-product of a rapidly industrializing economy.
However, China has embraced the concept of renewable energy with a massive shift towards solar energy. Legislation introduced by the Chinese government has been designed to spark investment in renewable energies and has so far, proved to be successful.
As the largest manufacturer of photovoltaic (PV) components, China has been a market leader in developing new products for markets elsewhere. Certainly, the Spanish market which experienced its own boom following the introduction of a feed-in tariff in 2007 relied massively on Chinese PV imports with the market experiencing a glut of Chinese produced PV plant when the Spanish industry went through its downturn and failed to install the solar plant which had been ordered. However, in a bid to alleviate some pollution problems and help meet climate change targets, the Chinese government has recently sought to increase the number of solar installations within the country.

In order to do this the government introduced a feed-in tariff system. Essentially, the feed-in tariff (FIT) was designed to attract investment in the new solar industry by offering financial incentives to investors.
The FIT mechanism operates on the basis that the law guarantees a fixed, premium rate for units of electricity fed-in to the grid by solar energy generators. The utility companies are obliged by the legislation to purchase the solar electricity at above market prices, the costs of which are passed on to the consumers. In China this mechanism which has been successful in areas such as Germany, Spain and California has also proved successful in China. In July 2009, the New York Times ran with the headline, "Green Power Takes Root in China" heralding the arrival of the Chinese PV market on the world stage.
The arrival of the Chinese PV industry has come in the form of a national renewable energy law which decrees that utilities must generate 8 per cent of their energy by renewable means by 2020. The fact that this 8 percent figure does not include hydroelectric power adds to the importance which the Chinese are now placing on green energy. The growing awareness of the lack of long-term sustainability in traditional coal energy sources has prompted the Chinese government to take action to maintain China has a major industrial power well in to the future. There has also been somewhat of a frenzy among private companies seeing the opportunities that will undoubtedly present themselves in the Chinese renewable industry, with a growing activity particularly in sectors such as wind and photovoltaic technology which will inevitably boom in China in the near future.
The New York Times was keen to use this Chinese government action to make comparisons with the comparatively weak efforts being made in Washington to spur the renewable sector in the United States.
Indeed, in the United Kingdom, with the recent feed-in tariff legislation, members of the green energy industry will be hopeful that government action in the UK will have the same effect it has had on the Chinese market.
The New York Times asserted its almost neurotic view of Chinese renewable growth compared to that of the US by warning,
"You won't just be buying your toys from China, you'll be buying your energy future from China."
China has a target in place to produce 8000 megawatts of energy by wind energy by 2010 which they are set to smash. If China continues apace to move towards green energy, they will surely shame efforts currently being made in the West to develop their own sustainable renewable industries.

Decorative Solar Outdoor Light

2011-06-17T08:51:00.002+03:00

Many homeowners who integrate solar outdoor light fixtures are unfamiliar with the manner in which they ought to care for their new solar outdoor light. Generally homeowners place the solar outdoor light where they think it will be most beneficial in terms of aesthetic quality and decoration. They place them around their garden, along a pathway, or around a porch. What many homeowners fail to recognize, however, is consideration of the amount of daily sun exposure that these lights will receive when placed in these areas of the landscape. Common problems associated with solar outdoor light is that the fixtures do not receive adequate lighting during the day and therefore cannot charge completely, leaving them dull and non-operational during the night hours when they are needed the most.
If this continues, then the batteries within the solar light will lose their lifespan and thus shorten the lifespan of
the fixture, costing homeowners more money than they need to spend. Also, solar outdoor light fixtures should be cleaned often to ensure that the solar panel receives enough light to recharge during the day. If the unit is covered with dirt and grime then it will be impaired in terms of recharging, also limiting the overall life span of the fixture. At the end of each season, homeowners will leave their solar outdoor light fixtures in the yard, even during winter when the yard is covered with ice and snow. This is not advisable. In fact, solar light fixtures should be turned off before freezing temperatures set in. They can also be removed and stored until spring arrives. If they are left outside during the shortened winter days, then they will receive less exposure to sunlight which will shorten the overall lifespan of the units.
When homeowners are searching for the perfect solar light fixtures, they sh9ould consider the placement of the solar lights before they purchase them. This will save time and frustration if you assume them to be more than just decorations. You should verify not just if the solar outdoor light fixtures will receive adequate sunlight, but also if the drainage is sufficient in a given area to prevent water damage and condensation. While solar outdoor light fixtures are water resistant, they are not waterproof. They can withstand sprinkler systems and rain, but not excessive water build-up. Therefore, excessive water can get into the unit and damage the electrical aspects as well as the battery. Homeowners should also consider how much light they wish to add to a given area at night.
Solar light fixtures should be used to add accent lighting to your landscape, not to provide safety lighting. Once these considerations have been made, the next step is determining which of the many available styles of decorative solar outdoor light fixtures will match your creative needs. The best way to create the optimum landscape design is to alternate the placement of additional features and plants to create a balanced look. This means that solar light fixtures should be staggered along a pathway instead of placed opposite one another along the path.

Solar Gadgets Can Save Lives

2011-06-15T22:59:00.001+03:00

Mobile Solar-powered Camel Hospitals

The right solar gadgets can save your life, if you are prepared. There are many tools, medical kits, and other life saving equipment out there, but are you choosing the right ones. A lot people stock up on batteries, which end up in spending a lot on batteries. The main reason that people are stocking up on batteries are for flashlights, lanterns, other portable electronics, well today I will tell you one tool that can and will save your life.
I was skimming though out the internet looking for some emergency supplies and I came across a device called the Hybrid SolarLite. This sounded really cool, and the price looked even better. I did some research and I even called Linda, she is one of the top ladies there. She told me some very important useful information I will share with you.
If you were to buy this solar flashlight it can last a single charge for 3 years. That is really awesome because when I have an area in my home for emergency supplies, I usually like to know that every works. I found out that 8 hours of charge in the sunlight, but hear this in roomlight will last up to 10 hours of continuous light.
One of the things I learned was that if you charged this solar gadget everyday, because you had to use it everyday you would be buying new batteries for free like every 5 hours because the batteries are rechargable. WOW...That is where they sold me. To think that I never have to buy new batteries for my emergency flashlight, and as long as there is sunlight, which just in about every country at least 1 or 2 times a week the sun shows itself. That the solar charger will be recharged for free. This solar gadget realistically pays for itself in about month if you were to compare it to how many times you buy batteries for your flashlight over a course of 6 months. I really like this product and I highly recommend it.
The other feature is that it is waterproof up to 80 feet. I am not a diver or big time swimmer, I figured people would love to know in case they fish at night, or swim, or boat. But do not worry about losing it in the water because it floats. This is a super packed about 5 in one flashlight, which will actually last.
I read somewhere and watched their videos which said it is perfect to put in your glove box or fishing box, boating cargo area. You can place these Solar Gadgets anywhere and use it anywhere!

Solar Spot Lights - Highlight the Best Features of Your Garden

2011-06-14T09:55:00.026+03:00

Solar Spot lights are handy fixtures that are used to draw attention of the onlookers on to a specific location. These small and trendy solar spot can be installed in gardens and are also safety options for sprawling spaces.

Conventional spotlights involve cable laying and digging up of the yard, which will destroy the ambience of your garden apart from costing a fortune. Solar lights sans cables can be used to light up water bodies, rock

gardens or an exotic color bed with style. Many homeowners also use solar lights to light up the perimeters of their homes, making it safe and welcoming during night hours. The dark and creepy corners of the yard a narrow doorway also could be ideal places where you can put solar spot to make it bright.

Solar spot lights have evolved to be trendy accessories that can be simply sunk into the soils and pan it in the appropriate location to light up specific spots in your garden. You can keep these on the whole night or can even set timers to detect sunrise and sunset. Solar spot lights are also used in arenas, sports complexes and commercial bill boards that require powerful lighting.
One of the advantages of solar lights is that these do not involve labour intensive trenching or cabling all across your garden. All you need to do is to find a suitable place where there is a steady supply of sunlight to position the solar spotlight and once the sun sets, your garden will glow with lights. The absence of cables and hooks would also mean that solar fixtures are easy to carry around and you can transfer the lights as and when required. In case your garden has seasonal trees and plants, you might find this feature tremendously useful as you might need to change the position to the lights to the flower beds that are in full bloom from a shrub that has shed its leaves!
Solar garden lights are excellent money savers as these do not involve any wire replacement or maintenance works and the recurring expense of power bills. It is recommended to bring the solar fixtures indoors in the event of harsh weather conditions like hail storm or snow fall.

Solar spot lights are great accessories to highlight your garden features and there are garden lights of various types and prices to suit your every need.

How to Calculate Solar Panel Watt Costs

2011-06-09T19:22:00.007+03:00

With our current economic melt down and energy prices fluctuating daily, many of us are thinking of installing solar panel power to contribute to our homes' energy needs, and reduce our power bills.

But how much solar panel watt power do we need to say halve our power bills? And how much will that power cost us to install?

Here is a four step process that you can follow to answer these two vital questions:

1 - Calculate Daily Power Used:

To do this, get your last 12 monthly power bills and calculate your average kilowatt hour (kWh) usage per month. The reason we use 12 is because our power consumption fluctuates with the seasons. But if you do not have all your power bills, then simply use last month's one.

Then divide your monthly usage by 30 (the average number of days in a month, to get your daily power used.

- So for example: If you have a monthly power consumption of 800 kWh, then your daily amount is 800/30= 26.7 kWh per day.

- Now if you want to only halve your power bill then you need to produce 26.7 / 2 = 13.4 kWh of solar panel watt power per day.

2 - Calculate Total Solar Panel Watt Needs:

To do this, you first need to determine how many usable hours of sunlight your area receives per day. This is where a solar insolation map comes in handy - you can view one from our original article on our website.

Once you know your daily sunlight hours, go back to your daily kilowatt hours needed and divide it by the daily sunlight hours, then multiply it by a factor of 1.25 (takes into account energy losses from the solar panel watt wiring, battery , and inverter)

- Continuing from our example: Our solar panel watt needs equal:

13.4 kWh / 5.5hrs x 1.25 = 3.045 kW or 3045 Watts per day.

This means we need solar panels with the capacity to produce at least 3045 Watts of power.

3 - Calculate Solar Panel Watt Costs:

This step will help you work out the cost of the solar panels needed to make 3045 Watts of power. At the moment the highest average cost for solar panels in the US is $4.85 per Watt.

- In our example: It will cost us at the most 3045 x 4.85 = $14,768 to install solar panels to halve our power bill. And that's before wiring, charge controllers, batteries, inverters, and electrician costs.

4 - Offset Tax Credits And Rebates:

Before we jump the gun and think it will cost us at least $14,768 for 3045 Watts of solar panel watt power, we need to take tax incentives and rebates in account.

With the new renewable energy tax credits going into effect from January 1, 2009, and state-side rebates from states such as New York, Connecticut, New Jersey or California, our solar installation costs will be much lower than expected.

- Let's use our example: If we were from California we would receive tax rebates of about 20% of the cost, and a federal tax credit of 40% on the remainder. So after rebates and credits, our solar panels would cost us:

$14,768 - $14,768 x (20%) - $14,768 x (1 - 20%) x 40% => $7,089.

Since there are many factors that go into calculating your solar panel watt costs, please only use our steps as a rough estimate. Some things were impossible for us to take into account, such as special offers by solar installation companies, where they offer you discounts on the full installation (including charge controller, inverter, battery, grid-tie electrician costs, etc).

Anyway, from what you can see it would cost us around $7,089 to buy enough solar panels to halve our power bill. We, instead, either get our solar cells at cost or source them for free, and wire up our own solar panels, which obviously saved us a lot of money. The good news is, anyone can learn to find cheap solar cells and make their own solar panel watt power.

Tesla: Free Energy

2011-06-07T12:17:00.005+03:00

Our current energy crisis can be solved and some of the solutions have been around for more than a century. One man saw the need for clean and abundant energy, his name was Nikola Tesla.

He was born in the Austro-Hungarian empire, in a village called Similian in Croatia and came to the United States in 1884 to materialize his inventions. In the US Tesla managed to find the solution that made possible the usage of electricity by anyone in their home. The dispute between Edison and Tesla regarding the transportation of electrical energy was eventually won by Tesla.

fearing that his lab would be destroyed like in New York. He was ecstatic when his enormous oscillator actually produced artificial lightning that was one hundred times more powerful than the spark he had previously obtained in his New York lab. During a violent storm in Colorado, Tesla made one of him most remarkable discoveries:

"I was observing the stationary waves... As impossible as it may seem, this planet, despite its vastness, acts like a normal, small conductor. The amazing importance of this fact for my energy transmission system became very clear in my mind. Not only can it be used to transmit telegraph signals wirelessly at any distance, as I said a long time ago, but also to propagate the modulations of the human voice on the entire globe. Even more so, the transmission of electrical power in unlimited quantities, at any distance and without losses," noted Tesla in his journal. His 9 month work in Colorado Spring is still sketchy. We know that he was able to transmit large quantities of electrical energy, wirelessly, through electromagnetic waves. There is information that he actually managed to transmit a signal at a distance of several miles.

Another thing that Tesla tried was to transmit energy through the ionosphere, at 80 km above the ground. Tesla believed that this part of the atmosphere is conductive, which proved to correct, but he lacked the technical means to transmit the energy at this altitude. There are ways to utilize the energy that surrounds us and Tesla's ideas can help us obtain alternative sources of energy that could one day set us free from the ones that pollute our planet and that could very well poison us all in a matter o

He argued that the usage of alternative current for the transportation of electrical energy was much more efficient than using the continuous current, as Edison wanted.

Tesla did not stop there and made further research on the wireless transmission of energy and the usage of solar power to accelerate the progress of humanity. He believed that the sun is what's keeping our planet alive and that is why he argued that the solution to our ever growing need for energy is to control

solar power. Here is how he described the advancement in this particular area, in an article published in the Century Magazine: "Using energy stored in wood and coal or generally speaking, fuel, led to the development of the steam engine.

The next giant step in energy transmission was made by using electricity, which allowed the transport of energy from one place to another without transporting the material itself. But in terms of environmental energy, no radical steps forward have been made". After analyzing different energy sources such as wind, the heat that comes from water or the earth, solar power, lightning power, Tesla came to the conclusion that these methods have their limitations. The future that he imagined over a century ago was still possible:

"It is possible, even probable to access other energy sources that are unknown to us at the moment. It is even possible to use magnetism or gravity to power cars without the use of other means"

He continued his research by imagining a flying disc powered by cancelling the force of gravity, an idea that would be studied by all the great scientific minds of the world for tens of years and even today. More than that Tesla imagined a thermal engine that uses the heat from the surrounding environment. The direct usage of solar energy also preoccupied him allot. "There is also the possibility, although unlikely, to obtain energy directly from the sun.

Other sources of energy might be discovered, even new ways to use solar energy, but none of these can compare to the importance of transmitting solar energy at any distance wirelessly. It would be the best way to increase the force that accelerates human mass", said Tesla about the importance of his discoveries made at Colorado Spring.

The Colorado Spring Experiment Tesla established his laboratory in 1899 in Colorado Springs, near Pikes Peak, hoping to make his dream come true: the wireless transmission of electrical energy through the ground or through the atmosphere. He kept a journal of everything he did in his laboratory f years.

Tesla free energy is the great big step ahead for humanity.

The Development Of Photovoltaic In New Emerging Market

2011-06-04T00:36:00.003+03:00

blog listing

It is predicated that the installment of photovoltaic in Germany will reach the peak in the next year, and the new emerging places of the solar energy module will in Asia, Europe and the Middle East. Fourteen places had taken ninety-five percent of the installment all over the world; therefore, the new emerging markets are expected to solve the saturation problem in the developed market. The ratio takes by the new emerging markets will increase from five percent to twenty-five percent in the year of 2014.

The Asia market will install most of the photovoltaic in the year of 2014, which will increase from 315MW to 3443MW. Europe, Middle East and Africa markets rank after the Asia market, and they will increase from 197MW to 2152MW. Currently, the installment is the most active, including China, Japan, Korea and so on. Germany is the largest photovoltaic market, and its quantity of installment reaches 8782MW in the end of 2010. But the Germany will reach the peak in the next year, and then it will decline gradually.

India will be in the leading position in the Asia market which has large population and increasing demand of electricity. The other Asian countries also made the positive development plan of photovoltaic market, including Malaysia and Philippines. What is more, Thailand has declaimed that it will establish a large-scale solar energy facility. In the new emerging market of Europe and Middle East, the solar energy is entering the small districts, including Israel, Turkey, Egypt and The United Arab Emirates. The long sunshine time and low influence of the environment enable the solar energy develop well in these districts. Because of the long sunshine time, Australia is also suitable to develop the photovoltaic, but its population is small. Therefore, it is predicated that its installment will increase in the future, but the scale is still small than the other districts. The related integrated circuit is HT7044A.

Solar Heaters

2011-06-03T00:45:00.001+03:00

Solar heaters and coolers can be used to offset the tremendous amount of energy that is used to heat and cool both residential and commercial buildings. It has been stated that heating, ventilation and air conditioning (HVAC) in the U.S., accounts for 30% of the power used in commercial buildings and nearly 50% of the total energy that is used in homes and apartments. We can take an active part in reducing our reliance on non-renewable energy sources by using solar devices.

Solar technologies are generally described as either passive or active, according to how the power is captured and converted. Collecting the energy from the sun, storing that heat and then converting it into usable energy has been man's dream for centuries. Now in modern days, we store the heat in what is called thermal mass materials. These can be materials as common as stone, cement and water or as exotic as photovoltaic arrays. The simple systems have been used since Roman times and are still common in the Middle East.

Solar heaters with air solar collectors are gaining popularity with the U.S. and Canada since the majority of the buildings in these countries already have an existing ducting system for air conditioning.

The heating and cooling exchange of solar energy has been used successfully for some time. Since the 1960's, solar roof 'ponds' have heated houses when it is cool at night and cooled the same house when it is hot during the day. Even before the last century, Auguste Mouchout produced ice using a steam engine (solar powered) to provide cooling. Not all of the equipment required is 'store bought'. You can increase the efficiency of your solar home devices by growing deciduous trees (the ones that shed their leaves in the winter) and paying attention to correct placement. There is much to learn about solar heating for your home or business.

Technology has advanced to the point where significant reduction can be made within the oil burning or electrical heaters or other air conditioning units, thereby giving all of us a new lease on life on this planet. I am not a drum beating liberal, so please do not take this the wrong way. I just feel that if we can give Mother Nature a helping hand from time to time, maybe we should consider doing just that.

How Solar Electricity Can Save You Money - And Make You Some Too

2011-06-01T22:15:00.002+03:00

In rural areas particularly, the cost of drawing from the nearest power grid far exceeds the cost of solar panel power, and the gap is increasing fast. And more and more many households in all sorts of areas - rural, suburban, and urban alike - are turning to home solar panel system as a source of backup power in case of a blackout or other emergency.
The cost of solar panel power per kilowatt hour is admittedly not the absolute cheapest of renewable energies - at around $0.55 per kWh as compared with $0.05 for wind or $0.06 for micro-hydroelectric, for example - but it's still markedly cheaper than paying the power company (especially with rate increases as much as 10% per year), providing of course - and here's the key: that you do it right.
If you're considering installing solar power in your home, then first things first: keep in mind that if you're planning for solar power to provide for all your home's energy needs, the cost of solar panel may take a significant up-front investment.

With the cost of solar panel alone at $275-$600 for each one, and each solar panel providing somewhere between 50 and 200 watts of power per day (depending on a variety of factors) it's not always cost-effective to plan to power your entire home exclusively with a home solar panel system.
That said, you can substantially reduce your home energy costs and even put some money back into your pocket by supplementing your existing power sources with a home solar panel.
To figure out the cost of solar panel systems to provide supplemental power to your home, it helps to perform an energy audit of your home, or - put plainly - an assessment of how much power you'd like your solar panel system to generate for you each day. To do this, take a look at the wattage of each of the electrical items that you might run in your home on any given day - microwave, TV, light bulbs, vacuum, refrigerator, fans, A/C, computer, etc., and add it all together.
This can be a very revealing process, especially if you've never done it before, and will surely help you to get a clearer idea of which items use the least power and which ones are your biggest energy drainers, and therefore a more accurate clue about your ultimate cost of solar power.
Once you feel you've compiled a reasonable list of electrical items you'd like to power with solar energy each day, calculate the cumulative wattage you'd use for all of them over a period of 24 hours. Now you can figure out how many solar panels, and thus the estimated cost of solar panel, you'll need.
Now if you currently live in a home that is not connected to any power grid, and you're trying to figure out the cost effectiveness of your energy options, then consider what we'll call "the half-mile rule". If the power company has to install more than a half-mile of equipment to get power out to your home, then the cost of solar panel power (or wind or hydro, for that matter) is cheaper straightaway.
If it's less than a half-mile for them to bring the power out to you, however, then it may be worth getting on the grid. Of course, again, after a few years of rate hikes you may wish you'd paid that cost of solar panel system after all. If, however, you do decide to connect to the power grid, remember that you can still install a smaller solar panel system anyway, one to act as a backup and provide you with supplemental energy. And that cost of solar panel system, obviously, will be much less.
In addition to the cost benefits of solar usage, you also benefit from a cleaner environment (not to mention a cleaner conscience). In fact, the cost of not using solar power - increased pollution and depletion of natural resources - is far greater than any up front cost of solar panel systems.
Finally, the cost of solar panel systems can be inordinately outweighed, as well, by two ways in which it could put money back into your pocket. You can sell to the local power company the excess power your home solar panel generates, if you're fortunate enough to have any (and in some states, it's actually required). And for a limited time, anyone in the United States can receive a tax credit on the cost of solar panel systems you install in your home. See the IRS for details.

Finding Cheap Solar Cells

2011-05-31T22:18:00.001+03:00

With tax breaks and economic savings, many people are implementing solar cell technology for homes. These solar cells reduce electricity costs while providing a renewable energy source that can end up paying for itself. This article discusses how to get the most power for the cheapest cost for solar cells.

Solar cells for homes can be very expensive, often being priced for at least one thousand dollars. The cheapest cell on one site was going for approximately seven hundred dollars, but was only rated for 60 watts. The trick, then, is to find a solar panel that can give a good power output, but be relatively cheap.

The best way to achieve this is to build your own solar panels. The cost of building a panel can be as little as $150, maybe $200 if you could find a good step-by-step guide with instructions and videos. A solar panel that has been built at home can be rated as high as 100 watts.

Most sites that sell 100-watt solar panels price them at around one thousand dollars. If assuming a home-built solar panel costs $200 to make, then for same price as buying a 100-watt solar panel, you could make a 500-watt solar panel. One site advertised individual solar panels for $15. A panel requires nine cells and if extra costs are calculated at $100, a cell could still be built for around $250.

That means even at that price, one could still make four panels rated at 400 watts total with the cost of buying just one 100-watt cell. Comparatively, the next closest panel would be a 50-watt rated panel that sells for around $350.

The bottom line is that in terms of getting the most amount of power for the least cost, buying solar panels is not even an option. The only true way to get cheap solar cells and panels is to make them yourself by using an easy to follow instruction guide. This will ensure that you will get the most economical solution that will pay for itself in no time.

Buying Solar Panels - 3 Money-Saving Secrets

2011-05-30T17:07:00.001+03:00

Everyone's starting to jump onto the bandwagon of using solar energy because it is believed to be the answer to the worsening energy crisis worldwide. But don't you think every thinking person must dig deeper first and know whether there are possible dangers in using these panels? Or at least be aware of the possible negative aspects of purchasing them? In this article, let us explore the possible drawbacks of patronizing this innovation. After all, buying solar panels is not like buying light bulbs.

1) Materials- Newer thin solar panels are made from materials which are harmful to the environment. Although they will not create any problem until you dispose the system (which is probably in the next two decades or so), it is imperative that you know they can cause trouble to the planet you are trying to save. Currently, new disposal and even recycling methods are being developed. Hopefully, these methods would become feasible by the time you need to dispose your solar panels.

2) Latest Technology- Many solar energy companies continuously do research on how they can improve or develop new products and systems. The research for renewable energy has actually become a big industry worldwide and new discoveries are being made at regular intervals. The thing is, not all products under experiments make it to the market. Some of them have huge market potentials but never really make it to the hands of the consumers. Just like other products going through research and development, solar panels using latest technologies sometimes do not work as expected. At times, they are just too expensive to produce. It is always some sort of a gamble to wait for breakthroughs. If you like to save the best for last, you may be waiting in vain. You should know when enough is enough.

3) Old Technology-Now, although waiting for the latest technology could not always be the best idea, it is also a big loss if you buy old technology. Meaning, since you don't want to wait any longer for the new breakthrough, you will just go for the cheaper technology available; thinking the idea is better when in fact, it is not. You may just spend thousands of dollars to buy solar panels which technology is almost obsolete.

Now, if you want to prevent this misfortune from happening to you, you must do your part to become a wise spender. Buying solar panels is not like buying light bulbs. They are much costlier and you really have to invest big in them. To make sure that you are getting ones which are worth your money, do your research. Use the internet, or better yet, hit the library. Business journals are available where product forecasts are published. These journals can give you an idea of what's to come and whether they are worth the wait. If not, you can always decide to go for what's currently available. Just make sure you pick the system which has been tested for sometime so even if the technology is relatively old, you know they truly work.

New Solar Technology Trends Around the World

2011-05-29T22:12:00.004+03:00

In the business of solar energy, the U.S. has not been the biggest buyer of solar power. While the U.S. does quite well exporting solar panels and solar technology, there are many Americans who still find the cost of panels very prohibitive. Plus, many states still don't offer the same sizeable solar power perks (tax credits, low interest loan programs) as many other nations in the world.

As the price of solar energy decreases, Europe has had a much higher demand for solar power than anywhere else in the world. Germany alone orders double the amount of solar panels sold in the U.S. ever year. Better yet, there's a bigger market for commercial solar power in Europe than in the U.S. Many European universities and campuses have rebuilt their dorms to run off solar energy. Most water heaters in Europe are solar-powered, even if the home doesn't have a full solar panel system.

A recent report released by Emerging-Energy.com states that between 2008 and 2020, Germany will become one the largest producers of solar panels in the world. In Europe, it's not just small residential power systems
that are leading the way in solar energy dependence. It's mostly large scale (over 1 MW) projects that have spurred new markets that have shaped a new landscape of energy usage in Europe. Such large projects have literally changed the way how utility companies and residential contract companies view solar energy. It's become increasingly easier for European business owners to purchase and install their panels with lowered tariffs and taxes.

Specifically, Italy, Greece and the Czech Republic are the newest customers of solar power systems. These countries have begun to purchase so much solar energy that their borders have seen changes in tariffs for solar panels. They've also seen major changes in permitting regulations that makes it easier for such private residences to have solar energy systems. In Italy, Greece and the Czech Republic, the demand for solar energy is the same in the private (residential) industry and the commercial industry. Conversely, most other European nations have seen a drastic rise in commercial industry demand, with residential demand remaining relatively stable.

Japan, who's also been at the forefront of solar panel imports, has picked up solar panel buying as the cost of gas and electricity rises. Japan has begun using solar panels in almost every new commercial and industrial building being built- including schools, hospitals and government facilities. There are entire neighborhoods in Japan outfitted with residential solar power panels. For example, the neighborhood of Iwaki New Town has about 46 homes outfitted with full private solar power panels. The neighborhood produces over 310,000 kWh in a single year, enough to power over 90 residences!

Japan also uses solar energy in surprising places. Japan is the only country to power most of its vending machines with solar energy. Sharp, one of the largest solar panel producing companies in Japan estimates that by 2010, Japan will produce 4.8 million kWh of solar energy. As a result, buying solar energy panels in Japan is inexpensive and has created one of the most profitable net-metering countries in the world.

Using the power of the sun definitely isn't going away anytime soon. In fact, solar energy may be the next step in energetic materials. If we equipped half the homes in America with solar panel systems, we could produce enough electricity to run the entire country. All it takes is one house at a time!

Interesting Facts About Solar Panels

2011-05-21T10:16:00.002+03:00

There is no doubt that solar energy is the future of energy. There is no need to highlight the constant search mankind has endeavor for cleaner and more efficient ways to supply energy. And the sun, once again, has come to the rescue. The beneficial effects of the sun impact on every aspect of life on the planet, from the smallest most humble forms of life to human beings. Without the sun it would be impossible to sustain any form of life. And, even more, sunlight has increasingly become a source of cheap and clean energy. You can make your own solar panels, and start little by little to make yourself independent of an obliged supplier: the power company. Start with a device, a water heater, for instance, or heating for one room. Pretty soon you will feel confident enough, as you gain the experience, to attempt bigger plans, such as completely relying on the sun to cover all your energy needs.

Before you make your own solar panels, here are some facts on how solar energy works, how it is collected and storage. Solar cells, also called photovoltaic (PV), are the core of any sun-powered device. They shyly started to be seen in small devices like calculators, half a century ago. Yes, that long, amazing, right? Solar cells were first developed in 1958. Remember how we used to play by covering the cell with one hand, and the calculator would turn off. The same technology started to be used in satellites in outer space; to cover the supply needs of power for this man made space crafts. Solar cells can "capture" up to 1.000 watts of energy every square meter. A group of cells is called a solar panel.

Solar cells are made of semiconductors, a special type of element that has the property of releasing electrons
when in presence of a source of energy, in this case, the rays of the sun. These free electrons will circulate, thus energy is produced. The stage that has proven most difficult to achieve is storage. So far, solar energy has been stored in batteries, like car batteries. Batteries have chemical substances that de-compose and release ions -electrically charged particles. As the energy is used, the substances inside the batteries turn back to their original chemical composition. This system has proven to be somewhat inefficient, due to the limited capacity batteries have. A large number of batteries would be required to store and supply energy to a regular family home, let alone bigger consumers, like a factory or a car. Hence, new ways of storing energy had to be developed.

First it was the sun that came to our rescue. Now, the water does. Yes, plain water has the capacity to store energy, basically based on the same principle batteries work: by decomposing a substance. In this case, water is decomposed in its two composing elements: oxygen and hydrogen. Then, these two gases can be recombined inside a battery, providing pollution free cheap energy.
