Hydroelectric power generates approximately 10% of the nation's energy. Credit: US Army Corps of Engineers. By capturing flowing water, it creates enough kinetic energy that can be captured and turned into electricity. We call this byproduct hydroelectric power or hydropower.

Commonly this is harnessed by a hydroelectric power plant, dam, reservoir, or a river. When water flows through a turbine, rotating propellers, which in turn activates a generator engine to generate electricity. However, hydroelectricity necessarily does not require an extensive dam. Hydroelectric power plants can use a small channel or waterway to create a channel water through a turbine. Energy collected from hydroelectricity can be obtained and stored for later use.

Generators will rotate turbines backward; this kinetic energy causes turbines to pump water of a river or reservoir to an upper reservoir, in turn, this is where power will be stored. Appropriating the potential energy, the water is released from an upper reservoir into a lower river or reservoir. Which, spins turbines forward, activating the generators to produce electricity.
