What are the limitations of extracting energy from
the wind, waves and tides.

Answers
Answer:
Answer: (a) Limitations of extracting energy from the wind: Wind flowing with a sufficient speed is not available everywhere and all the time. Thus wind is not a dependable source of energy. The kinetic energy of wind (wind energy) can be used only at the site of windmill.
Answer:
Waves:- Like tides, generating energy from waves is possible and profitable n very few places as there is an uncertainity over generating energy from waves. Also the cost of building these generators are very high.
Tides. There are very few sites around the world which are suitable for building tidal dams. The rise and fall of sea-water during high and low tides is not enough to generate electricity on a large scale.
Winds:- 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. Also, wind energy cannot be completely reliable as it depends upon the blowing winds.
