Write two different ways of harnessing enegry from ocean.

Explanation

Two different ways of harnessing energy from ocean are :
(i) Tidal energy : Tidal energy or tidal power can be defined as the energy that is the result of the Moon and the Sun.s gravitational influence on the ocean. Height differences between high and low tides create tidal currents in coastal areas, and these currents can be strong enough to drive turbines. The turbine fixed at the opening of the dam converts tidalenergy to electricity.

(ii) Ocean thermal energy: OTEC uses the principle of a heat engine. It works by converting a temperature difference into energy. This means the difference in temperature between the warmer water on the surface and the cooler water in the depths of the ocean can be converted into electricity.
