Which of these statements about hydroelectric power is true?

a. it uses civilization's earliest energy to produce electricity.
b. it uses water's potential energy to produce electricity.
c. it uses a safe, renewable resource.
d. it disrupts one of earth's never-ending cycles.

B. It uses water's potential energy to produce electricity.

Explanation:

Hydroelectric power is a renewable source of energy. This energy is obtained by capturing the energy from the water tides in the ocean or any other water body.

The potential energy stored in water tides is converted into mechanical energy or kinetic energy by the water turbines. The energy from yielded after the movement of turbines used for electricity production.
