MCQ
Tidal energy is harnessed by :
  • A
    Transporting sea water to a close dam.
  • B
    Constructing a submerged dam.
  • ✓
    Constructing a dam across a narrow opening to the sea.
  • D
    Constructing an overhead dam.
✓

Answer

Correct option: C.
Constructing a dam across a narrow opening to the sea.
Difference in sea $-$ levels due to tides during different times of day 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 converts tidal energy to electricity.
