The combination of electrical generators and hydraulic turbines allows hydropower systems to convert the potential energy of dammed or flowing water into storable electrical output. Although this conversion relies on relatively simple mechanical properties, the system employed to achieve it is often complex in its design and capabilities. Harnessing the motion of water to power machines and mechanical processes is one of the oldest methods of power generation currently in use. Today, there are thousands of hydropower plants in the United States, providing a notable percentage of the country’s electricity supply.
