Think of coal like wood. In a wood stove or furnace, wood is burned to produce heat. Coal contains more energy and is cheaper that wood, however wood is renewable. The large coal power plants that run use coal to produce heat by burning it, heating water. When water heats up to steam, it has more pressure. This pressure is used to turn generators. The electricity produced will be direct current. The power plant will have a converter to change the DC into AC, Alternating Current.
