Hydroelectric power, or hydroelectricity, is generated by the force of falling water
The water is held behind a dam, forming an artificial lake, or reservoir. The force of the water being released from the reservoir through the dam spins the blades of a giant turbine. The turbine is connected to the generator that makes electricity as it spins. After passing through the turbine, the water flows back into the river on the other side of the dam.
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
Generates electricity by purely mechanical means
The U.S. Energy Information Administration believes that, because of the abundance of water on earth, hydroelectricity will provide a significant amount of humanity's future energy needs. The properties of a body of water will determine what type of system can harness its potential energy.
The most common dams are built out of earth and rock with a water-proof core inside to prevent water damage.
Sites are limited by available dams and dams which meet the properties
