Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.
Coal is converted into electricity through a complex process that involves steaming, grinding, processing and distribution. The act of transforming coal into electricity is quite a production; coal is first ground to a fine chalky powder and added to combustion chambers of boilers before being burned at higher temperatures to produce hot gas and heat energy.

Dec 16, 2019· Coal can be converted into a gaseous state or into a liquid and still be used as if it were refined or raw. The conversion to a liquid or a gas creates a fuel that burns cleaner as well, which limits the production of ash and other byproducts that are created by the combustion process. 6. Coal can be used with renewables to reduce emissions.
