coal be useful in many ways especially for powering electricity
Coal is a fossil fuel and is an energy and heat resource. (It is used for energy and heat) It is used in steam trains to power the trains and is a useful resource for many things. It is formed from the remains of trees and plants which grew a long time ago. They sank into the ground and were pressed under layers of rock. As it dried up, it turned into peat, (a type of soil) then coal.
