Why are energy sources like sunlight, wind and water reservoirs described as suitable for green energy generation?
AThey are perpetual and avoid pollution
BThey release more carbon dioxide too
CThey produce radioactive waste also
DThey burn completely without residue
Answer & Solution
Correct answer: A. They are perpetual and avoid pollution
1. Sunlight, wind, water and biofuels are never-ending, that is, perpetual.
2. Using them does not cause the air pollution or fuel-depletion problems of coal and gas.
3. So electricity from them is environment friendly, called green energy.
4. They are not burnt and do not release carbon dioxide (option B), so that is ruled out.
