Duke Energy has been using coal to produce electricity in the Carolinas since 1911. Those first coal-fired plants (in Greensboro, N.C., and Greenville, S.C.) only supplemented the company’s use of hydroelectricity. In the 1920s, the growing demand for electricity began to outstrip the availability of hydroelectric generation.
In a coal-fired power station, a boiler burns coal to produce steam. The steam makes a turbine spin. The turbine drives an electricity generator.
