Question

What are the limitations of extracting energy from −
(a) the wind? (b) waves? (c) tides?

Answer 1

a) 1-large area is required for construction of wind mills
2- wind speed should be 15km/hr
b) wave energy can only be extracted in the areas recieving high waves
c) there should be a noticible difference between high and low tide

plzz mark it as the brainliest if it helped

Answer 2

Hello Dost ☺

Answer :

a) The wind: Wind energy is trapped using windmills. One of the limitations of the wind energy is that the windmills requires a speed more than 15 km/h to generate electricity. And the number of windmills will be more to cover a huge area.

b) Waves: In order to extract energy from the waves, very strong ocean waves are needed.

c) Tides: In order to extract energy from the tides, the sun, the moon and the earth should be in a straight alignment and the tides should be very strong.
