Questions and Answers

What is the working principle of tidal power plants?

  • Using solar energy to generate electricity from tidal waves
  • Converting wind energy into electricity through tidal turbines
  • Harnessing the potential energy of tides for power generation (correct)
  • Utilizing geothermal heat to produce power from tidal movements

    • How are tidal power facilities similar to hydroelectric power?
