Question

How is tidal energy harnessed?

• A. Dam is constructed at certain height above sea that converts tidal energy to electrical energy.
• B. Dam is constructed across a narrow opening of sea which converts tidal energy to electrical energy.
• C. Kinetic energy of the waves of water is converted to electrical energy.
• D. None of these.

Answer 1

The correct option is A

Dam is constructed at certain height above sea that converts tidal energy to electrical energy.

To harness the energy of tides, dam is constructed across a narrow opening of sea so there is always a difference in the level of water between two sides which causes flowing of water and rotation of turbine to convert tidal energy to electrical energy.
