It can be used to generate electricity byīurning it but the efficiency is limited. Gasoline is an important transportation fuel. Otherwise it is messy to handle and bulky for tranport and The obvious advantage of coal is that it is cheap if it is used as a heat Whereas the coal and gasoline would typically need to be converted to heatĪnd then into some other form of energy before being useful.
