Why the World Still Uses Coal, Oil and Natural Gas

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.

Comparing and Contrasting Oil and Solar Power As Energy Sources

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.
