Question

what are the limitations of the energy that can be obtained from oceans??

Answer 1

Tidal energy, wave energy, and ocean thermal energy are various forms of energy that can be obtained from the sun. But there are several limitations to harness these energies. Those limitations are

(i)High dams are required to be built to convert tidal energy into electricity which incurs lot of cost.

(ii)       Very strong waves are required, which are not possible all the time.

(iii)     Tidal energy depends on the relative positioning of the Earth, moon, and the Sun. 

(iv) To harness ocean thermal energy the difference in the temperature of surface hot water and the cold water at depth must be 20ºC or more.

I have written it by myself please mark it as the brainllist if it will help you please say thanks for this answer too. . . .

Answer 2

Explanation:

The forms of energy that can be obtained from the ocean are tidal energy, wave energy, and ocean thermal energy. There are several limitations in order to harness these energies.

→ Tidal energy depends on the relative positioning of the Earth, moon, and the Sun.

→ High dams are required to be built to convert tidal energy into electricity.

→ Very strong waves are required to obtain electricity from wave energy.

→ To harness ocean thermal energy efficiently, the difference in the temperature of surface water (hot) and the water at depth (cold) must be 20ºC or more.
