2. Micro hydro - Wikipedia

   en.wikipedia.org/wiki/Micro_hydro

   Power electronics now allow the use of permanent magnet alternators that produce wild AC to be stabilised. This approach allows low speed / low head water turbines to be competitive; they can run at the best speed for extraction of energy, and the power frequency is controlled by the electronics instead of the generator.

3. Pico hydro - Wikipedia

   en.wikipedia.org/wiki/Pico_hydro

   A pico hydro system made by the Sustainable Vision project from Baylor University [1]. Pico hydro is a term used for hydroelectric power generation of under 5 kW. These generators have proven to be useful in small, remote communities that require only a small amount of electricity – for example, to power one or two fluorescent light bulbs and a TV or radio in 50 or so homes.

4. Water turbine - Wikipedia

   en.wikipedia.org/wiki/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 .

5. Electricity generation - Wikipedia

   en.wikipedia.org/wiki/Electricity_generation

   Water Energy is captured by a water turbine from the movement of water - from falling water, the rise and fall of tides or ocean thermal currents (see ocean thermal energy conversion). Currently, hydroelectric plants provide approximately 16% of the world's electricity. The windmill was a very early wind turbine. In 2018 around 5% of the world ...

6. Micro combined heat and power - Wikipedia

   en.wikipedia.org/wiki/Micro_combined_heat_and_power

   While net-metering is a very efficient mechanism for using excess energy generated by a micro-CHP system, it does have disadvantages: while the main generating source on the electrical grid is a large commercial generator, net-metering generators "spill" power to the smart grid in a haphazard and unpredictable fashion. However, the effect is ...

7. Hydroelectricity - Wikipedia

   en.wikipedia.org/wiki/Hydroelectricity

   Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. The power extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. This height difference is called the head.
