OverviewCalculating the amount of available powerDisadvantages and limitationsApplicationsRain powerHistorySee alsoExternal links

Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity

Hydroelectric Power: Energy Source Fact File!

Hydro-electric power does not produce any carbon dioxide emissions when using water to produce electricity. Electricity can be generated 24 hours a day as long as there is enough water. But this can''t happen every day as the reservoir needs time to fill up again from time to time. The dam gates can be opened and closed to control when the ...

Hydroelectric Power Plant

Hydroelectric Power Plants are used where Water is at a height. In Hydroelectric Power Plant, Potential Energy of the Water at a height is converted into Mechanical Energy by Rotating the Turbines. . This Mechanical energy is further converted into Electrical Energy. To put the water at a height, we use Dams.

Hydroelectric Energy: The Power of Running Water

Hydroelectric energy is made by moving water. Hydro comes from the Greek word for water. Hydroelectric energy has been in use for thousands of years. Ancient Romans built turbines, which are wheels turned by flowing water. Roman turbines were not used for electricity, but for grinding grains to make flour and breads.

Hydropower

Hydropower. Hydropower is energy derived from flowing water. More than 2,000 years ago, the ancient Greeks used waterpower to run wheels for grinding grain; today it is among the most cost-effective means of generating electricity and is often the preferred method where available. In Norway, for example, 99% of electricity comes from hydropower.
