When burned, this coal releases twice the heat-trapping emissions as natural gas. It also holds about 40 percent more ash content than the average coal lump. In addition to producing grime, ash lowers the coal burning temperature, which means that power plants need to use more coal to make a megawatt. It's a vicious circle, Donohue says.
