Question

Why any source of energy has less consequence? Explain your example with a suitable example.

Answer 1

1. Any source of energy whether the renewable or non-renewable source of energy contributes to environmental pollution directly or indirectly.
2. Let us take the example of hydro energy.
3. Hydro energy does not emit any air pollutants but it harms the environment in the following ways:
   (a) Since dams always have a reservoir where an abundant quantity of water is stored, the blocking of flowing water causes harm to aquatic animals and their migration.
   (b) Dams also cause submerging of the nearby lands and all the natural areas, and agricultural lands and hence require relocating of the people who lived previously near the dam area.
   (c) In the case of wind energy the windmill blades are injurious to the birds.
