A hydroelectric dam is essentially a mechanical gateway that can control how often, how much, and how fast the water is allowed to passed through. Water above the dam is collected and stored into a reservoir.
Another major use of dams is power generation as hydroelectric power is one of the worldâs major sources of electricity. Hydropower is generated when the potential energy of the water on the dam drives a water turbine which in then turns a generator and creates electricity.
