  2. Water storage - Wikipedia

    en.wikipedia.org/wiki/Water_storage

    Water storage. Water storage is a broad term referring to storage of both potable water for consumption, and non potable water for use in agriculture. In both developing countries and some developed countries found in tropical climates, there is a need to store potable drinking water during the dry season. In agriculture water storage, water is ...

  3. Pumped-storage hydroelectricity - Wikipedia

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

    Pumped-storage hydroelectricity ( PSH ), or pumped hydroelectric energy storage ( PHES ), is a type of hydroelectric energy storage used by electric power systems for load balancing. A PHS system stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.

  4. 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 [1] and improve the daily capacity factor of the generation system. Pumped storage is not an energy source, and appears as a negative number in ...

  5. Water cycle - Wikipedia

    en.wikipedia.org/wiki/Water_cycle

    The water cycle (or hydrologic cycle or hydrological cycle ), is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time. However, the partitioning of the water into the major reservoirs of ice, fresh water, salt water and ...

    Clean water technology can be found in the form of drinking straw filtration. Used as solution by Water Is Life, the straw is small, portable, and costs US$10 per unit. The filtration device is designed to eliminate waterborne diseases, and as a result, provide safe drinking water for one person for one year. Emas pump

  7. Grid energy storage - Wikipedia

    en.wikipedia.org/wiki/Grid_energy_storage

    One approach is to reuse unreliable vehicle batteries in dedicated grid storage [57] as they are expected to be good in this role for ten years. [58] If such storage is done on a large scale it becomes much easier to guarantee replacement of a vehicle battery degraded in mobile use, as the old battery has value and immediate use.

  8. Irrigation - Wikipedia

    en.wikipedia.org/wiki/Irrigation

    Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes ...

  9. Water supply network - Wikipedia

    en.wikipedia.org/wiki/Water_supply_network

    The water is typically pressurised by pumping the water into storage tanks constructed at the highest local point in the network. One network may have several such service reservoirs. In small domestic systems, the water may be pressurised by a pressure vessel or even by an underground cistern (the latter however does need additional pressurizing).
