Question

Why are fossil fuels called depletable sources of energy?

Answer 1

Fossil fuels are called a depletable source of energy because:

1. Depletable natural resources are those which have reserves within a limited time span and will be finished in due course of time.
2. These resources once depleted cannot be replenished back.
3. It takes millions of years for the formation of fossil fuels.
4. The rate at which we are using them is very fast compared to the rate of their formation.
5. Due to this, fossil fuels are a depletable source of energy in nature.
