Coal is a combustible, sedimentary, organic rock, which is composed mainly of carbon, hydrogen
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 109 years of coal remaining worldwide.
Not only does coal provide electricity, it is also an essential fuel for steel and cement production, and other industrial activities.
