Hydroelectricity is electricity generated by hydropower, i.e., the production of power through use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably lower output level of the greenhouse gas carbon dioxide (CO2) than fossil fuel powered energy plants. Worldwide, hydroelectricity supplied an estimated 816 GWe in 2005. This was approximately 20% of the world's electricity, and accounted for about 88% of electricity from renewable sources.
Industrial hydroelectric plantsWhile many hydroelectric projects supply public electricity networks, some are created to serve specific industrial enterprises. Dedicated hydroelectric projects are often built to provide the substantial amounts of electricity needed for aluminum electrolytic plants, for example. In the Scottish Highlands of United Kingdom, there are examples at Kinlochleven and Lochaber, constructed during the early years of the 20th century. The Grand Coulee Dam, long the world's largest, switched to support Alcoa aluminum in Bellingham, Washington, United States for American World War II airplanes before it was allowed to provide irrigation and power to citizens (in addition to aluminum power) after the war. In Suriname, the Brokopondo Reservoir was constructed to provide electricity for the Alcoa aluminum industry. New Zealand's Manapouri Power Station was constructed to supply electricity to the aluminum smelter at Tiwai Point. As of 2007 the Kárahnjúkar Hydropower Project in Iceland remains controversial.

What industries rely on hydro power?
Electric power industry and manufacturing rely on hydro power. Most of the electricity that is generated by hydroelectric plants in the United States of America use hydro power.
What is an advatage of using coal power over solar power to generate electricity?
coal power can be generated at night
Why do power plants produce AC power naturally?
AC (alternating current) is the primary form of electricity because it can be generated at very high voltages and sent across many, many miles of carrying lines.
Where does electrisity come from?
electrisity comes from big electricity generators .
How is hydroelectric energy stored and how is it released?
There are schemes where water is pumped up into a reservoir with pumps that can be reversed and become generators when peak power is required. There is one at Dinorwic inWales UK. Ofcourse any hydro scheme can include storage, the water stored in the reservoir is potential energy to be released when required.
Is hydro power and hydro electricity the same thing?
Yes, hydro power and hydroelectricity refer to the same thing. It is electricity generated by harnessing the energy of moving water using turbines in hydroelectric power plants.
What industries rely on hydro power?
Electric power industry and manufacturing rely on hydro power. Most of the electricity that is generated by hydroelectric plants in the United States of America use hydro power.
What is generated in a hydro-electric power plant?
Hydroelectric power plants generate electricity by the action of the "falling" water spinning a turbine which rotates a wire inside a big magnet.
What percent of the world electricity is supplied by hydro power?
16% of the world's electricity is generated by hydropower (water power).
What percent of the worlds electricity is supplied by hydro-power?
16% of the world's electricity is generated by hydropower (water power).
What percent of the worlds electricity is supplied by hydro electricity?
16% of the world's electricity is generated by hydropower (water power).
What fraction of Finland's electricity is generated by water power?
10-20 %. For example year 2010 14,5% of all electricity supply in Finland was generated by hydro power.
How does hydro electricity flow?
Hydro electricity is electricity generated by moving water, usually from dams nowadays. Electrical power is all the same. It flows through wires.
What plant is electricity made in?
Electricity is not made in plants. Most electricity is generated in power plants using a variety of sources such as coal, natural gas, nuclear, hydro, wind, and solar energy. Plants utilize photosynthesis to convert sunlight into chemical energy, but they do not produce electricity.
How electricity is generated in Colorado?
Power plants.
How is electricity generated in south south?
Power Plants! Fossil fired / coal fired Nuclear No Hydro electrical No Wind powered Solar Panels in some houses
Where is hydro electricity located?
Just means generated by water power can be found in powerplants and factories
