What is hydroelectric power?
Hydroelectric energy, also called hydroelectric power or hydroelectricity, is a form of energy that harnesses the power of water in motion—such as water flowing over a waterfall —to generate electricity. People have used this force for millennia.

How many hydroelectric dams are in the world?
The dams store river water which, when released, powers turbines and generators to create electricity. More than 3,500 hydropower dams are being planned or built around the world, according to a database maintained by Christiane Zarfl (and others) at the University of Tubingen.
How much energy is produced by a small hydroelectric generator?
Microhydropower systems usually generate up to 100 kilowatts of electricity . Most of the hydropower systems used by homeowners and small business owners, including farmers and ranchers, would qualify as microhydropower systems.
