Coal is a variety of solid, combustible, sedimentary, organic rocks, formed from vegetation that has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years. Carbon is the main component of coal, which also contains varying amounts of other components, like hydrogen, oxygen, sulphur and other impurities. Main parameters used to define coal are calorific value, ash, moisture and sulphur. Many different classifications of coal are used around the world, reflecting a broad range of ages, composition and properties.
Coal use triggered during the Industrial Revolution and never stopped growing globally. Coal use will be significant also in the future. The IEA believes that greater effort are needed by government and industry to embrace cleaner and more efficient technologies to ensure that coal becomes a much cleaner source of energy in the decades to come.
