Answer 2

The two main reasons to harness non-conventional sources of energy are:

(i) The population of the world is increasing at a very rapid rate due to which demands for energy is increasing day by day.

As, fossil fuels like coal, petroleum, are present in a limited amount which and are likely to finish one day so the need for alternative sources of energy is essential.

(ii) Use of conventional sources of energy (coal, petroleum etc.) causes pollution. To reduce pollution use of non-conventional sources of energy is essential.
