Answer: One of the limitations of extracting energy from wind is that a windmill requires wind of speed more than 15 km/h to generate electricity. Also, a large number of windmills are required, which covers a huge area. (b) Very strong ocean waves are required in order to extract energy from waves

Answer:

(i) The Wind:

(a) It is not available at all times.

(b) It requires a very large area of land.

(c) It is not possible to have a windmill everywhere as to run it, the minimum wind speed of 15 km/hr is required (only possible in open areas like the seaside).

(ii) Waves:

(a) Wave energy would be a viable proposition only where waves are very strong.

(b) It is costly to set up devices to trap wave energy.

(iii) Tides:

(a) Very few sea coasts in the world have suitable sites for the purpose of harnessing tidal energy.

(b) The rise and fall of tides happen only twice in a day is not sufficient to generate electricity continuously.
