The construction of the "hydroelectric power" is an efficient way of making more electricity to benefit humans.

Explanation:

Hydropower plants capture the dynamism of tumbling water to produce electricity. A turbine changes the kinetic energy of tumbling water into powered energy. Then a generator changes the mechanical energy from the turbine into electrical energy. Hydropower is one of the oldest power sources on the planet, producing power when flowing water spins a wheel or turbine. It was utilized by farmers as far back as ancient Greece for mechanical tasks like grinding grain. Hydropower is also a renewable energy source and produces no air pollution or toxic by products.
