2. Solar-powered pump - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_pump

   A windpump replaced by a solar-powered pump at a water hole in the Augrabies Falls National Park. [Notes 1] This solar water pump up to 3.7 kW is useful for farmers.Solar-powered pumps run on electricity generated by photovoltaic (PV) panels or the radiated thermal energy available from collected sunlight as opposed to grid electricity- or diesel-run water pumps.

3. Solar energy use in rural Africa - Wikipedia

   en.wikipedia.org/wiki/Solar_energy_use_in_rural...

   In the article by Burney et al. (2010) [6] another use for solar energy that has been proposed is the Photovoltaic- (or solar-) powered drip irrigation (PVDI) system [which] combines the efficiency of drip irrigation with the reliability of a solar-powered water pump... [Where the] PV array powers a pump (either surface or submersible ...

4. Zero-energy building - Wikipedia

   en.wikipedia.org/wiki/Zero-energy_building

   A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site [1] [2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows ...

5. Water well pump - Wikipedia

   en.wikipedia.org/wiki/Water_well_pump

   These pumps, often submersible and powered by electricity, can access water reserves located much deeper than shallow wells, ensuring a consistent supply even during periods of drought. They include different kinds of pumps, most of them submersible pumps: Hand pump, manually operated; Injector, a jet-driven pump

6. Dispatchable generation - Wikipedia

   en.wikipedia.org/wiki/Dispatchable_generation

   Non-dispatchable renewable energy sources such as wind power and solar photovoltaic (PV) power cannot be controlled by operators. [2] Other types of renewable energy that are dispatchable without separate energy storage are hydroelectric , biomass , geothermal and ocean thermal energy conversion .

7. List of appropriate technology applications - Wikipedia

   en.wikipedia.org/wiki/List_of_appropriate...

   Solar, special Einstein refrigerators and thermal mass refrigerators reduce the amount of electricity required. Also, solar and special Einstein refrigerators do not use haloalkanes (which play a key role in ozone depletion), but use heat pumps or mirrors instead. Solar refrigerators have been built for developing nations by Sopology. [41] [42]
