What are the lumitation of extraction energy from wind? For class10?
Answers
Limitations of extracting energy from above sources are
(a) A windmill requires wind of speed more than 15 km/h to generate electricity from wind energy. Also large numbers of windmills are required to get feasible output which covers a large area.
(b) Very strong ocean waves are required in order to extract energy from waves. But these are not available all the time?
(c) Very high tides are required in order to extract energy from tides. But tides depends on the relative positions of the Sun, moon, and the Earth.
