Hydropower creates electricity.
The first power plant was built in Bavarian in 1878
the hydropower was used by greeks and in 250 b.c
The first commercial nuclear power plant in the US was built in 1957 in Shippingport, Pennsylvania. The first commercial nuclear power plant in the world was built in 1956 in Calder Hill, UK.
Worldwide, hydropower plants produce about 24 percent of the world's electricity and supply more than 1 billion people with power. The world's hydropower plants output a combined total of 675,000 megawatts, the energy equivalent of 3.6 billion barrels of oil, according to the National Renewable Energy Laboratory. There are more than 2,000 hydropower plants operating in the United States, making hydropower the country's largest renewable energy source.In this article, we'll take a look at how falling water creates energy and learn about the hydrologic cycle that creates the water flow essential for hydropower. You will also get a glimpse at one unique application of hydropower that may affect your daily life.
Once the power plant is built, there is almost no pollution from the actual running of the plant.
dam
penstock
The giant tube in a hydropower plant is called Penstock. A Penstock is refers to the enclosed pipe that delivers water to the hydro turbines.
The transformation of energy take place in hydropower plant includes:Potential energy -> kinetic energy-> electrical energy

They use flowing water to spin a generator.
Hydropower is the cheapest way to generate electricity today. No other energy source, renewable or nonrenewable, can match it. Producing electricity from hydropower is cheap because, once a dam has been built and the equipment installed, the energy source-flowing water-is free. Although Hydropower does present a few environmental problems the inherent technical, economic and environmental benefits of hydroelectric power make it an important contributor to the future world energy mix,
