Hello dear friend !!!
Here you go ....
The alternate rise and fall of water of the ocean twice in nearby 24 hours is known as tide. The tides are caused due to the gravitational force of attraction exerted by the moon and to some extent by the sun on the water of the ocean.
At the time of new and full moon, when the sun and the moon are in a straight line, tides are very high. When the sun and the moon are at right angle from the Earth, tides are low. The kinetic energy of water waves during tides is used to produce electricity.
Tidal power plants are constructed near narrow bays . During tides, the gates of the dam are opened. The rising water is allowed to fall on the turbine of the generator which produces electricity.
Thus kinetic energy of water is converted into electrical energy.
During low tides, gates of the dam are closed and hence the water level behind the dam rises. This raised water has potential energy. Again the gates are opened and water is allowed to fall back into the Bay. This falling water is used to rotate the turbine of the generator.
France and Canada are the leading countries which hardness the tidal energy. In India three sites namely, Gulf of Kutch, Gulf of Cambay, and Sundarbans have been identified to construct the tidal power plants.

Tidal energy is produced through the use of tidal energy generators. These large underwater turbines are placed in areas with high tidal movements, and are designed to capture the kinetic motion of the ebbing and surging of ocean tides in order to produce electricity.
