Coal is a flammable black hard rock used as a solid fossil fuel.It is mainly made up of 65-95% carbon and also contains hydrogen, sulphur, oxygen and nitrogen.It is a sedimentary rock formed from peat, by the pressure of rocks laid down later on top.The harder forms of coal, such as anthracite, are metamorphic rocks because they were changed by higher temperature and pressure.
So total fuel and operating costs for a typical coal plant is 2.83 cents per kilowatt hour. Since the median age of existing coal plants is 44 years, most are already fully amortized. That means their owners have fully paid off the construction costs, and operating and fuel costs are the only components of cost.
