  2. Hydropower - Wikipedia

    en.wikipedia.org/wiki/Hydropower

    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. [1] Hydropower is a method of sustainable energy production.

  3. Hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Hydroelectricity

    Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. [2] A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response ...

  4. Electricity generation - Wikipedia

    en.wikipedia.org/wiki/Electricity_generation

    Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines fueled by combustion or nuclear fission, but also by other means such as the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power. There are exotic and speculative ...

  5. Water power engine - Wikipedia

    en.wikipedia.org/wiki/Water_power_engine

    The hydrosphere's inventor Rick Dickson states it can generate up to 500 megawatts of continuous renewable energy. Air–water gravity generator – Another invention from Rick Dickson, believed to be the hydro plant of the future. Pressured water is let into the Air – Water- Gravity generator which generates power by entering a vacuum ...

  6. Water turbine - Wikipedia

    en.wikipedia.org/wiki/Water_turbine

    The runner of the small water turbine. A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work. Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation.

  7. Pumped-storage hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Pumped-storage...

    During off-peak hours, the turbine changes direction and pumps the water out again, using "surplus" electricity from the grid. The quantity of power created when water is let in, grows proportionally to the height of the column of water above the sphere. In other words: the deeper the sphere is located, the more densely it can store energy.

  8. Kelvin water dropper - Wikipedia

    en.wikipedia.org/wiki/Kelvin_water_dropper

    This energy comes from the gravitational potential energy released when the water falls. The charged falling water drops do work against the opposing electric field of the like-charged containers, which exerts an upward force against them, converting gravitational potential energy into electrical potential energy, plus motional kinetic energy.

  9. Osmotic power - Wikipedia

    en.wikipedia.org/wiki/Osmotic_power

    This method was described by Weinstein and Leitz as “an array of alternating anion and cation exchange membranes can be used to generate electric power from the free energy of river and sea water.” The technology related to this type of power is still in its infant stages, even though the principle was discovered in the 1950s.
