What is coal? originenergy.au

Most people know coal as a fossil fuel which is used to produce around 40 percent of the world's electricity. 1 It's a flammable black or brown sedimentary rock, and is made mostly of organic carbon. However, there are actually two main types of coal 'thermal' coal, which is mostly used for power generation, and 'metallurgical' coal, which is mostly used for steel production.

APPENDIX Comment on US reports. It is evident that apart from heat discharged with combustion gases from a coal-burning plant and any difference in thermal efficiency which affects the amount of heat to be dumped in the cooling system, there is no real difference in the amount of water used for cooling nuclear power plants, relative to coal-fired plants of the same size.
