Coal is an abundant fuel source that is relatively inexpensive to produce and convert to useful energy. However, producing and using coal impacts the environment. Climate change is one of the greatest environmental challenges we face. Climate impacts affect the entire planet.

4 Coal Mining and Processing Coal: Research and

Removal of the mineral matter (or “ash”), 3 which is largely noncombustible and may constitute up to 65 percent of the raw coal, increases the heating value of the coal on a mass basis. 4 Although some combustible material is lost as part of the cleaning process, the removal of unwanted material reduces the mass and volume of coal for a given heating value thereby reducing shipping costs as well as
