Question

List three energy sources that are considered to be inexhaustible. State three reasons in support of your answer.

Answer 1

Hint: Inexhaustible sources of energy are the renewable source of energy that can be obtained from sun, wind, water etc. That can be constantly replenished.

Complete answer:
Energy sources that can be considered as inexhaustible are:
1) Wind energy: Wind is a naturally blowing fast air. The energy of the wind is captured by the wind mills to rotate it and thus converting the mechanical energy to electrical energy. This electrical energy can be used by small areas as a source of energy.
2) Solar energy: Solar cells, solar battery, solar air conditioner, solar cooker etc. are all based on the solar energy. The heat of the sun is converted into electricity and is stored and can be used for later purposes.
3) Hydro energy or water energy: Hydroelectricity is mainly used in the area with river tributaries. The fast flowing water provides energy which is converted into different forms and can be supplied to the houses.
The sources are considered as in exhaustible because of the following reason:
a) Energy obtained from these sources can be replenished.
b) The energy of the sun, wind and water can never come to an end and therefore are considered as inexhaustible and renewable.
c) These sources are naturally occurring sources.

Note: Inexhaustible sources of energy do not come to an end and can be replenished naturally. These are generally obtained from natural sources such as the energy of the sun, energy of the fast blowing wind and the energy of the fast flowing water. Tidal energy and biomass energy are also a form of renewable source of energy.
