Question

Which statement describes the principles on which tidal energy works?

Kinetic energy in the motion of water is converted to electricity.
Potential energy in the motion of water is converted to electricity.
Chemical energy from salt water is converted to electricity.
Mechanical energy from water is converted into electricity.

Answer 1

The statement that best describes the principles on which tidal energy works is:

**Kinetic energy in the motion of water is converted to electricity.**

Tidal energy harnesses the kinetic energy of moving water caused by the gravitational pull of the moon and the sun, as well as the potential energy from the differences in water height (tides). However, in the context of the options given, the kinetic energy aspect is the most directly related to tidal energy generation.
