Coal is a national resource whose use affects everyone. Coal is America’s most readily available, least expensive, and most abundant major fossil fuel resource. Burning coal generates over half of our nation’s electricity. Coal is also used directly by industries and manufacturing plants. When coal is burned it produces coal ash. Fly ash, bottom ash, and boiler slag are the primary forms. Fly ash can be used as a partial replacement for cement in concrete; as a low cost filler in golf balls, tennis rackets, screwdriver handles, plastics, bowling balls and linoleum. Bottom ash is often used in concrete blocks and as a base in road construction. Boiler slag is used in roofing shingles and as a blasting abrasive.
