Following are the two sources of energy that are exhaustible:
(i) Wood: The source of wood are forests. Due to deforestation, the number of forests are reducing. We know that it takes years to grow forest. If the rate of deforestation increases, the availability of wood will decrease. Hence, wood is an exhaustible source of energy.
(ii) Coal: The source of coal is from the dead remains of the plants and animals that remained buried for years. Industrialization has increased the demand for coal, and it cannot be replenished. Hence, coal is also an exhaustible source of energy.Answered by Shivani Kumari | 2 years ago
