With only 6% of the world''s total water resources and 9% of the world''s arable land, China feeds 21% of the world''s population. This achievement was not possible without a huge number of water conservancy projects, e.g. dams, reservoirs, irrigation infrastructure, and water transfer projects. Today, China possesses the largest number

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 the upper reservoir (recharge).
