Hydropower (from Ancient Greek ὑδρο-, "water"), also known as water power or water energy, 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. [1] Hydropower is a method of sustainable energy ...
In this way the easily regulated character of hydroelectricity is used to compensate for the intermittent nature of wind power. Conversely, in some cases wind power can be used to spare water for later use in dry seasons. An example of this is Norway's trading with Sweden, Denmark, the Netherlands, Germany and the UK.
The Hoover Dam, when completed in 1936, was both the world's largest electric-power generating station and the world's largest concrete structure. Hoover Dam power station. Hydroelectricity is, as of 2019, the second-largest renewable source of energy in both generation and nominal capacity (behind wind power) in the United States. [1]
Micro hydro is a type of hydroelectric power that typically produces from 5 kW to 100 kW of electricity using the natural flow of water. Installations below 5 kW are called pico hydro . [ 1 ] These installations can provide power to an isolated home or small community, or are sometimes connected to electric power networks, particularly where ...
Watermill of Braine-le-Château, Belgium (12th century) Interior of the Lyme Regis watermill, UK (14th century). A watermill or water mill is a mill that uses hydropower.It is a structure that uses a water wheel or water turbine to drive a mechanical process such as milling (grinding), rolling, or hammering.
The first power plants used water power or coal. [7] Today a variety of energy sources are used, such as coal, nuclear, natural gas, hydroelectric, wind, and oil, as well as solar energy, tidal power, and geothermal sources. In the 1880s the popularity of electricity grew massively with the introduction of the Incandescent light bulb.

The mechanical power needed to assist in this production is provided by a number of different sources. These sources are called prime movers, and include diesel, petrol and natural gas engines. Coal, oil, natural gas, biomass and nuclear energy are energy sources that are used to heat water to produce super-heated steam. Non-mechanical prime ...
