Overview:

After food, fossil fuel is humanity's most important source of energy. There are three major fuels -- coal, oil and natural gas. Coal is used primarily to produce electricity. It therefore provides us with light, motive power from electric motors, and our many electronic devices. Oil gives us our mobility, our cars, planes, trains, trucks and boats. Natural gas is used primarily to produce heat, for our buildings, hot water, and industrial processes.
