Question

what are limitations of energy obtained from the sea​

Answer 1

Answer:

Energy from the oceans can be obtained in the form of tidal energy, wave energy and ocean thermal energy. But these energy sources suffer from the following limitations: There are very few locations where dams to utilise tidal energy can be built.

Answer 2

Explanation:

Tidal energy, wave energy, and sea 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 sea thermal energy the difference in the temperature of surface hot water and the cold water at depth must be 20ºC or more.
