Question

Combustion of fossil fuels generates a lot of air pollution. Can you suggest any two alternative sources of energy which do not cause any pollution?​

Answer 1

Fossil fuels generate a lot of air pollution when they undergo combustion. Instead of these, we can use alternative sources of energy like:​

Solar energy: Solar panels can be installed which would harness or use the solar energy of the sun to run machines or generate power.​

Wind energy: In wind energy, the wind is used as a source of energy. Wind turbines can be installed which generate energy when turned.​
