Hydropower is a renewable source of energy . ... Hydropower is fueled by water, making it a clean source of energy. Hydroelectric power won’t pollute the air like power plants that burn fossil fuels, such as coal or natural gas.
How the hydroelectric power is generated?
At hydropower plants water flows through a pipe, or penstock, then pushes against and turns blades in a turbine to spin a generator to produce electricity. ... The facilities may have a weir in the water course to divert water flow to hydro turbines.
How are hydroelectric power and coal generated power different?
Actually, hydroelectric and coal-fired power plants produce electricity in a similar way. ... A coal-fired power plant uses steam to turn the turbine blades ; whereas a hydroelectric plant uses falling water to turn the turbine. The results are the same.
What are the three ways to generate hydroelectric power?
LEARN MORE. There are three types of hydropower facilities: impoundment, diversion, and pumped storage . Some hydropower plants use dams and some do not.

Hydropower has the ability to generate electricity without emitting greenhouse gasses. However, it can also cause environmental and social threats, such as damaged wildlife habitat, harmed water quality , obstructed fish migration, and diminished recreational benefits of rivers.
Why hydropower is not clean energy?
Hydropower dams and reservoirs emit methane, a greenhouse gas that is 20 times more potent than carbon dioxide. These emissions are caused by the decomposition of organic vegetation flowing into the water as the reservoir levels fluctuate, and as rivers and floodplains are flooded each year.
What are the problems with hydroelectric power?
Hydropower has the ability to generate electricity without emitting greenhouse gasses . However, it can also cause environmental and social threats, such as damaged wildlife habitat, harmed water quality, obstructed fish migration, and diminished recreational benefits of rivers.
Who uses hydropower the most?
