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.
Why hydropower is bad?
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 invented hydropower?
Hydropower became an electricity source in the late 19th century, a few decades after British-American engineer James Francis developed the first modern water turbine. In 1882, the world’s first hydroelectric power plant began operating in the United States along the Fox River in Appleton, Wisconsin.
What are the top 3 hydropower producing states?

What is the largest hydroelectric dam in the world?
The Three Gorges Dam on the Yangtze River in China is the world’s biggest hydroelectric facility.
How much electricity does hydropower produce?
Hydropower is the most efficient way to generate electricity. Modern hydro turbines can convert as much as 90% of the available energy into electricity. The best fossil fuel plants are only about 50% efficient. In the U.S., hydropower is produced for an average of 0.85 cents per kilowatt-hour (kwh) .
