How could this energy source be used?

The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water is released from the reservoir. Water is released from the reservoir flows through a turbine, spinning it, then the turn activates a generator to produce electricity...

Hydropower is the most important and widely-used renewable source of energy.
Hydropower represents 19% of total electricity production.
China is the largest producer of hydroelectricity, followed by Canada, Brazil, and the United States (Source: Energy Information Administration).
Approximately two-thirds of the economically feasible potential remains to be developed. Untapped hydro resources are still abundant in Latin America, Central Africa, India and China.
