Although there are many different types of fossil fuels, we have chosen three that we feel are especially important: coal, petroleum, and natural gas. Because virtually all fossil fuel uses produce energy in pretty much the same way (see the Theory section), we have condensed them into one area on this website.

Fossil fuels have been a widely used source of energy every since the Industrial Revolution just before the dawn of the 20th century. Fossil fuels are relatively easy to use to generate energy because they only require a simple direct combustion. However, a problem with fossil fuels is their environmental impact. Not only does their excavation from the ground significantly alter the environment, but their combustion leads to a great deal of air pollution.
