Question

why is there a need to harness non-conventional sources of energy give two main reasons

Answer 1

non conventional source are mainly fossil fuel. they are available in limited stock. with the increase in population their consumption has increased. So rate if consumption is very high as compared to the formation of fossils. so it is important to harness non conventional source of energy.

Answer 2

hey friend

there is a need to harness non-conventional sources of energy because:

◆ conventional sources of energy are exhaustible while non-conventional sources of energy aren't exhaustible.

◆ conventional sources of energy produce much pollution such as use of coal releases harmful gases in air but if we dispose radioactive material (from non-conventional sources) properly it won't cause pollution .

hope it helps :)
