Which of the following are true of wind energy?

1.It is an intermittent energy

2.It is extremely useful at remote and isolated places

3.It does not depend upon the weather

4.It is a clean energy

5.It does not have any environmental impact at all

A1, 2 & 3 only

B1, 2 & 4 only ✓ Correct

C2, 3 & 4 only

D3, 4 & 5 only

Correct answer: (B) 1, 2 & 4 only

Explanation

Wind energy is intermittent, especially useful at remote and isolated places, and a clean source.

Statement 1 holds, as wind is variable and does not blow steadily.

Statement 2 holds, since turbines can power off-grid remote sites.

Statement 4 holds, because wind generation emits no pollutants during operation.

Statement 3 fails, as wind output depends directly on weather conditions.

Statement 5 fails, since turbines still affect birds, noise and land use.

Wind now supplies a large share of India's installed renewable energy capacity.
