Question

define:- 1)ocean thermal energy 2) wave energy 3) tidal energy

Answer 1

1)ocean thermal energy:
The ocean water is warm on the top and is cool in the bottom and this difference in temperature is exploited to obtain energy in plants that are known as ocean thermal energy conversion plants.

Wave energy:-
The kinetic energy possesed by huge waves near the sea shore can be trapped in a similar manner to generate electricity.

Tidal energy:-
Due to gravitational pull of mainly moon on the spinning earth the level of water in the sea rises and falls. This difference in sea levels gives us tidal energy
