Question

Write a short note on tidal energy

Answer 1

tidal energy is the energy obtained from the rise and fall of sea or ocean waters. a high tide occurs once in a day whereas a low tie occurs twice. the main advantage is it is a renewable source of energy and doesn't cause any environmental pollution. the main disadvantage is the tidal power plants can't be constructed everywhere, the construction cost is more, it doesn't produce much energy, it is not reliable. in India there are very few tidal power plants.

Answer 2

Hey mate here is your answer-

____________________________________________________________

Due to the gravitational pull of mainly the moon on the spinning earth, the level of water in the sea rises and falls. If you live near the sea or ever travel to some place near the sea, try and observe how the sea-level changes during the day. This phenomenon is called high and low tides and the difference in sea-levels gives us tidal energy. Tidal energy is harnessed by constructing a dam across a narrow opening to the sea. A turbine fixed at the opening of the dam coverts tidal energy to electricity. As you can guess, the locations where such dams can be built are limited.
