Question -
Answer -
a. The wind?
b. Waves?
c. Tides?
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.
