Potential energy stored in water.
Hydro energy
A dam is used for hydroelectric energy.
Hydro means fluid power and in this case that fluid is flowing water, usually a dam. el is electric So, hydro electric power or hydroelpower is electricity generated using flowing water from a dam.
Water is stored behind a dam and possesses potential energy. When it is released and made to run down conduits down the dam to turn turbines the potential energy is converted to kinetic energy which in turn is converted to electrical energy.
Water stored behind a dam is an example of potential energy (energy of position). As the water flows through the dam, some of the water's potential energy is converted into kinetic energy (energy of motion), which is typically further converted into electrical energy through the use of spinning magnets and coils of wire.
Kinetic Energy.
"water energy" = Hydro electricity. Depending where the dam is, it can be detrimental to the environment. Also, nuclear is cheaper.
Hydro-electric energy is the energy captured from the movement of water. Usually a dam is built which stores the water behind it. Water is released through the dam turning turbines which generate electricity.
Technically speaking, the molecular movement of water and how fast the molecules vibrate, the energy of that can be captured and the form of energy can be used to generate electricity. They use the hoover dam to do that.
Potential energy is the state of matter in which it is not at rest, or at its lowest state. A charged battery has potential energy, as does the water behind an hydro dam.
Can we produce power (electricity - www.powerfromgravity.com) from gravitaitonal (not from dam) force by using buoyancy from renewable source of energy?
The Aswan dam is an embankment dam.
