Eg- coal, pretloleum.

(b)Exhaustible sources are those sources of energy which will exhaust or dissappear after some time. Eg - coal, petroleum. Inexhaustible sources are those sources of energy, which will not exhaust from nature. These are unlimited source of energy. Eg - sun

Therefore, we can say that, (a) and (b) are almost the same.
