What are the limitations of extracting energy from :
I ) The Wind II) Waves III) tides .

Explanation

(i) Limitations of extracting energy from the wind: Wind flowing with a sufficient speed is not available everywhere and all the time.
(ii) Limitations of extracting energy from ocean waves : Wave energy would be commercially viable only at places where the waves are strong. The energy produced from waves has to be transmitted through long distances at the possible of use.
(iii) Limitations of extracting energy from tides : There are very few sites suitable for harnessing tidal energy. The rise and fall of water during tides is not very large. So, large scale generation of electricity is not possible.
