Question

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

Answer 1

Answer:

The limitations of ocean energy are: (i) Few limited sites/places where this wave, tidal or ocean thermal energy can be obtained.

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.
