Question

A hydroelectric power plant uses the transformation of ______ energy to ______ energy to generate electricity.

Answer 1

1. A hydroelectric dam converts the potential energy stored in a water reservoir behind a dam to mechanical energy, mechanical energy is also known as kinetic energy.
2. As the water flows down through the dam its kinetic energy is used to turn a turbine.

Hence, a hydroelectric power plant uses the transformation of potential energy into kinetic energy to generate electricity.
