  • Generating Electricity from Coal - Duke Energy

    It is used to generate a substantial amount of our electricity – about 37%. The challenge? Finding ways to burn it more sustainably. Historically, a wide variety of environmental impacts are associated with generating electricity from coal. Since 1923, Duke Energy has designed and built our own coal .

  • Coal & electricity | World Coal Association

    Steam coal, also known as thermal coal, is used in power stations to generate electricity. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high ...
