Coal Wikipedia

Coal is also used to produce very high temperatures through combustion. Efforts around the world to reduce the use of coal have led some regions to switch to natural gas and electricity from lower carbon sources. When coal is used for electricity generation, it is usually pulverized and then burned in a furnace with a boiler.
