Hi and welcome back to my youtube channel. Hydroelectric power sometimes referred to as
hydroelectricity is dependent on moving water. Water is the largest single renewable energy
source responsible for electricity generation in the world. Hydroelectricity power plants generate
electricity using the kinetic and potential energy of water. The water drives turbines that in
turn drive generators which convert mechanical energy into electricity. At facilities called
hydroelectric power plants, hydropower is generated. Some power plants are located on rivers, streams
and canals but for a reliable water supply dams are needed. Dams store water for later release for such
purposes as irrigation, domestic and industrial use, and power generation. The reservoir acts much
like a battery, storing water to be released as needed to generate power. Once the electricity
is produced it must be delivered to where it's needed: our homes, schools, offices, factories, etc...
Dams are often in remote locations and power must be transmitted over some distance to its users
Large hydropower plants are the biggest power-producing facilities in the world.
Some hydropower stations even have twice the capacity of the current largest
nuclear power stations. So here are the largest hydropower plants in the world.
