Answer:
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.
Limitations of extracting energy from ocean waves: Wave energy would be commercially viable only at places where the waves are strong.
Limitations of extracting energy from tides: a) There are very few sites around the world which are suitable for building tidal dams. b) The rise and fall of sea-water during high and low tides is not enough to generate electricity on a large scale.
