Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Duke Energy has used coal to produce energy in the Carolinas since 1911. The first coal-fired plants in Greensboro, N.C., and Greenville, S.C., originally only supplemented the company's use of hydroelectricity. This changed in the 1920s when energy demand exceeded what the hydroelectric stations could generate.
