FOSSIL FUEL:








              Fuels are natural substances that have


                  chemical energy stored in them. This energy

                  is released when we burn them.



              Most of the energy we use comes from fossil


                  fuels, such as coal, natural gas and

                  petroleum.



              Coal is used in power plants for generating


                  electricity and also to make steel.



              Petroleum is used in vehicles and natural

                  gas is used for cooking.
