What is Pumped Storage Hydropower? Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into

Strictly speaking, however, energy is conserved in our universe, according to the first law of thermodynamics. Terms such as "generated" or "lost" are common in conversations about energy. When teaching about energy, however, use terms such as convert, flow, distribute, store, release, transfer, transform, input, and outflow.
