Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago. All living plants store .

The total amount of coal in the world is so large (equivalent to about 150,000 quadrillion BTU) that the possession of even a small fraction represents a major economic benefit (see Review Question 72). Great Britain has as little as 1%% of the world's coal, and yet it was the world's leading coalproducing nation for over a century.
