Hydroelectric power is produced with moving water
Since the source of hydroelectric power is water, hydroelectric power plants are usually located on or
near a water source. The volume of the water flow and the change in elevation (or fall) from one point
to another determine the amount of available energy in moving water (...)
(...) the water flows through a pipe, or penstock, then pushes against and turns blades in a turbine to
spin a generator and produce electricity. In a run-of-the-river system, the force of the current applies
pressure on a turbine. In a storage system, water accumulates in reservoirs created by dams and is
released as needed to generate electricity.
