Question:

Why is there a need to harness non-conventional sources of energy? Give two main reasons.

Answer:

Non- conventional resources are the renewable process of energy which is continuously replenished (refill or freshen up again) by the natural resources. Electricity or energy generated by the wind by windmills, biomass, solar energy; all are the examples of non-conventional resources.

Two main reasons for the need to harness non- conventional sources of energy are following:-

1. Exhaustible resources like fossil fuels take millions of years to form and decrease in these resources in future lead to the shortage for the future generation which in turn has serious repercussions on the growth of the natural economy; but non-conventional resources like wind, solar energy can be used continuously. Thus non- conventional resources need to be harnessed for future use.

2. Exhaustible resources pollute the environment when they are being used while non- conventional did not produce any harmful effect on the environment. They are pollution free, renewable, environment friendly so they are the best choice.
