'''Coal''' is a combustible material which was formed by decomposing plant and animal material placed under intense pressure. [[China]] is the largest producer and consumer of coal in the world.

[[Coal mining]] is the extraction of coal for use as a [[fuel]]. It became important after 1800 as coal fueled railroads of the [[Industrial Revolution]], and (where cheap water power was not available), the factories. Coal is now the chief method of generating [[electricity]], along with burning natural gas, using water power in dams, and using nuclear energy.
