Write a short note on Energy from the sea.

1.	Write a short note on Energy from the sea.
Answer» • Tidal Energy: Locations in India – Gulf of Kutch, Gujrat & W. Bengal (i) Depends upon harnessing the rise and fall of sea level due to tidal action. (ii) Dams are constructed across a narrow part of sea and turbine converts tidal energy into electrical energy. Disadvantages: Uniform tidal action is not seen • Wave Energy: (i) Kinetic energy of the waves of sea are used to rotate turbines. (ii) These turbines generate electrical energy
