  2. Hydropower - Wikipedia

    en.wikipedia.org/wiki/Hydropower

    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 ...

  3. Renewable energy - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy

    Renewable energy often displaces conventional fuels in four areas: electricity generation, hot water/space heating, transportation, and rural (off-grid) energy services. [22] Although almost all forms of renewable energy cause much fewer carbon emissions than fossil fuels, the term is not synonymous with low-carbon energy.

  4. Water resources - Wikipedia

    en.wikipedia.org/wiki/Water_resources

    Hydroelectric power derives energy from the force of water flowing downhill, driving a turbine connected to a generator. This hydroelectricity is a low-cost, non-polluting, renewable energy source. Significantly, hydroelectric power can also be used for load following unlike most renewable energy sources which are intermittent. Ultimately, the ...

  5. Renewable resource - Wikipedia

    en.wikipedia.org/wiki/Renewable_resource

    Renewable energy may replace conventional fuels in four distinct markets, namely electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services. [48] Manufacturing of renewable energy devices uses non-renewable resources such as mined metals and land surface .

  6. Hydroelectricity - Wikipedia

    en.wikipedia.org/wiki/Hydroelectricity

    When the demand becomes greater, water is released back into the lower reservoir through a turbine. In 2021 pumped-storage schemes provided almost 85% of the world's 190 GW of grid energy storage [2] and improve the daily capacity factor of the generation system. Pumped storage is not an energy source, and appears as a negative number in ...

  7. Water - Wikipedia

    en.wikipedia.org/wiki/Water

    Hydroelectric power comes from water driving a water turbine connected to a generator. Hydroelectricity is a low-cost, non-polluting, renewable energy source. The energy is supplied by the motion of water. Typically a dam is constructed on a river, creating an artificial lake behind it.

  8. Renewable energy in the United States - Wikipedia

    en.wikipedia.org/wiki/Renewable_energy_in_the...

    Renewable energy technologies encompass a broad, diverse array of technologies, including solar photovoltaics, solar thermal power plants and heating/cooling systems, wind farms, hydroelectricity, geothermal power plants, and ocean power systems and the use of biomass.

    Variable renewable energy sources are those that have a fluctuating nature, such as wind power and solar power. In contrast, controllable renewable energy sources include dammed hydroelectricity, bioenergy, or geothermal power. Renewable energy systems have rapidly become more efficient and cheaper over the past 30 years.
