Oil and natural gas result from

• the migration of complex carbohydrate molecules to nonporous rock formations.

• the decay of tiny marine organisms that accumulated on the ocean floor millions of years ago.

• dinosaur flatulence trapped in rocks.

• the burning of high-sulfur, low grade uranium.

Inside the combustion chamber of a coal-fired power plant,

• the turbine sets the generator in motion.

• electricity is generated.

• gasoline is produced.

• burning fossil fuels release energy in the form of heat.
