Twoexhaustible energy sources are as follows:
(a) Coal: It is producedfrom dead remains of plants and animals that remain buried under theearth’s crust for millions of years. It takes millions of yearsto produce coal. Industrialization has increased the demand of coal.However, coal cannot replenish within a short period of time. Hence,it is a non-renewable or exhaustible source of energy.
(b) Wood: It is obtained from forests.Deforestation at a faster rate has caused a reduction in the numberof forests on the Earth. It takes hundreds of years to grow a forest.If deforestation is continued at this rate, then there would be nowood left on the Earth. Hence, wood is an exhaustible source ofenergy.
