Fossil fuels
Energy from fossil fuels (coal, oil and natural gas) comes from substances which originated from the accumulation, millons of years ago, of large quantities of remains of living beings at the bottom of lakes and other sedimentary depressions. By clicking on the following controls you can learn more about each one of these fuels.
