Leaky Clues to Dam Design: How Reservoir Height Affects Hydroelectric Power Production …
Dams block the flow of a river or stream and create a lake or reservoir behind them, which acts as a source of stored energy (a battery is another example of a reservoir of stored energy). The dam raises the surface water up to a great height, giving it potential energy, the potential to do work. the potential to do work.
Pumped storage plants convert potential energy to electrical energy, or, electrical energy to potential energy. They achieve this by allowing water to flow from a high elevation to a lower elevation, or, by pumping water from …
