Coal is a valuable and plentiful natural global resource
Not only does coal provide electricity, it is also an essential fuel for steel and cement production, and other industrial activities.
Coal is a combustible, sedimentary, organic rock, which is composed mainly of carbon, hydrogen and oxygen. It is formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams. Coal is a fossil fuel and is far more plentiful than oil or gas, with around 112 years of coal remaining worldwide.
