Question

What are the limitations of extracting energy from:
A) wind
B) Water waves
C) sea /ocean tide

Answer 1

A. wind mill requirs higher cost of installation

B. Water waves are not available every time

C.Ocean tides require large amount of kinetic energy to convert into electrical energy

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.
