Fossil fuels are are hydrocarbons, primarily coal, fuel oil natural gas formed from the remains for dead plants and animals. This type of energy is cheap, reliable and is well developed. Fossil fuels powered us for decades and that is why fossil fuels are well developed. But there are some major problems with creating this type of energy. It contributes global warming, it is not renewable and some accidents and happen like the Fossil fuel spill in the gulf of Mexico. This days, fossil fuel is pushed behind. Our world wants clean and renewable energy instead of energy that creates pollution. Fossil fuels can be used when the problem is fixed. But, the energy is not renewable and it can’t be renewable with today’s technology. So, that is why fossil fuels are disappearing out of our sights.
