What is tidal energy?

• A. A form of renewable energy that uses the natural rise and fall of tides to generate electricity.
• B. A type of energy from the sun.
• C. Energy from wind.
• D. Geothermal energy stored underground.

Answer: (A)

Tidal energy is energy captured from the regular rise and fall of ocean tides, driven by the gravity of the Moon and Sun. This makes it renewable and predictable, since the tide cycle repeats consistently and isn’t consumed by use. In practice, devices either route tidal currents through turbines (tidal stream) or use a barrage to trap water at high tide and release it through turbines at low tide, converting the moving water or water head into electricity. It differs from solar energy, wind energy, and geothermal energy, which rely on solar radiation, wind patterns, or underground heat, respectively. Tidal energy works best in coastal areas with strong, predictable tides.
