List any four reasons why we need to look for alternate sources of energy.

Answer :

We need to look for alternative sources of energy because:

(a) The conventional sources such as fossil fuels like coal, petrol, diesel etc. are non-renewable and are limited in nature. If we continue to use them at the present rate, then they won’t last long.

(b) The burning of fossil fuels pollutes the environment by releasing harmful gasses in the environment which can lead to health hazards.

(c) The major gas released is carbon dioxide which is responsible for the greenhouse effect. This leads to global warming which itself is one of the main environmental issues.

(d) The alternative sources like the solar energy, hydroelectric energy, wind energy etc. use the renewable source of energy and also do not cause the pollution.

The use of alternative sources of energy has manifold advantages over the usage of fossil fuels.
