How are fossil fuels used to make energy?

Answer 1

They are mostly used in internal combustion or external combustion engines.

Fuel for internal combustion engines is used in cars, buses, trains, airplanes, and rockets. It is also used in steel plants' furnaces to heat the production of steel. Examples of fossil fuels include coal, gas, gasoline, and heavy oil. Engines transform chemical energy into first heat energy and then mechanical energy.
