Question

what are the limitations of extracting energy from:. a) the wind. b) waves. c) tides​

Answer 1

Explanation:

Limitations of extracting energy from wind:-

a) For extracting energy, atleast a speed of 15km/hr is needed, which is not available everywhere.

Limitations of extracting energy from waves:-

a) Very strong ocean waves are required in order to extract energy from waves.

Limitations of extracting energy from tides:-

a) Very high tides are required in order to extract energy from tides. Also, occurrence of tides depends on the relative positions of the Sun, moon, and the Earth.

Answer 2

Answer:

(a) Wind energy is not sufficient to operate heavy machines and moreover it is limited to a certain place.

(b)Energy of the waves can be extracted only if strong wind blows all the time across the sea.

(c)Tidal power plant can extract the tidal energy from the water levels of high tide and low tide is very large.
