Question

what are the limitations of extracting energy from wind, waves and tides?

Answer 1

hloo
(a) Limitations of wind energy:
(i) need a large open space to install a number of wind mills.
(ii) can be tapped only during specific periods when the wind speed is above 15 km/h.
(iii) wear and tear of windmill parts is quite high.
iv) The set up of wind mills is not economical.
(b) Limitations of wave energy:
Wave energy is viable, only where the waves are very strong. That is, it has constraints of time and location.
(c) Limitations of tidal energy:
i) The height of tidal waves limit the production of tidal energy.
ii) Location where such dams can be built and the tapping of such energy is difficult. The huge amount of silt gets
deposited on basins in the dams.



hope it works

if it is good ans then

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.
