Overview of Generation of Electricity using Tidal Energy

Tidal energy is one of the important form of marine Energy. The tidal energy is extracted from naturally occurring phenomena of rise and fall of the ocean's water level. When the angle made by sun, and moon with respect to earth is zero degree the highest and lowest tides produced due to adding up of pulling forces, called spring tides. When the angle made by moon and sun with respect to earth is 90 degree, the tides produced are not as high or low as at other times of the month, called neap tides. Tidal energy is one of the most predictable and promising form of ocean energy due to its non-polluting, clean, reliable, and non-depleting nature. Number of techniques like Tidal barrages, tidal stream turbines to harness tidal energy are under development. Thus, they provide the best opportunity to harness energy from the oceans. In this paper, the Indian tides location and some tide location all over the world, tidal power plants all over the world are discussed.
