Question

The pollutant free energy resource are:
(A) coal
(B) nuclear power
(C) petroleum
(D) solar energy

Answer 1

Hint: Generally renewable source of energy is pollutant free. It means energy that is sustainable and something that can’t run out or is endless, like the sun. It helps to conserve the nation’s natural resources.

Complete step by step answer:
When energy is obtained from natural and renewable sources are generally pollutant free. Solar energy, wind energy are renewable sources of energy and do not produce pollution.
Coal is a combustible black rock with a high amount of carbon and hydrocarbon coal is a non-renewable source of energy. It pollutes air on burning.
Nuclear energy is also called atomic energy.
It produces a significant amount of energy during the process. Nuclear power is the use of nuclear reactions that release nuclear energy to generate heat. Nuclear energy produces radiations.
Petroleum is naturally occurring liquid found in the earth. It is used as fuel in vehicles, heating units and machines. It produces air pollution.
Therefore. From the above discussion it concludes that solar energy is pollutant free.
Solar energy is truly a renewable source of energy.
1] Reduces electricity bill
2] Low maintenance cost
3] Diverse Application
4] It is weather dependent
5] Storage is expensive

Therefore, the above explanation is the correct option is (D) solar energy.

Note:
Solar energy is among the world's cleanest forms of energy, but some disadvantages are also there.
1] Location and availability
2] Installation area
3] Inefficiency
4] Expensive energy storage
5] High initial cost
