What is coal used for?

Coal is primarily used as fuel to generate electric power in the United States The coal is burned and the heat given off is used to convert water into steam which drives a turbine In 2012 about 39 percent of all electricity in the United States was generated by coal-fired power plants according to the U S Energy Information Administration Get price
