POWER SOURCE

Power source is a physical or chemical phenomenon whose energy can be exploited for economic or biophysical purposes. According to a first classification criterion, they are called "primary" if they come from a natural phenomenon and have not been transformed (the sun, biomass, water currents, 1 the wind, energetic or radioactive minerals); and "secondary" if they are the result of an intentional transformation from the primary ones to obtain the desired form of energy2 (electrical energy -which can be obtained from any of the primary sources-, the chemical energy of the different fuels used for transport, heating or industry -which can be obtained from very different sources-, etc.) According to a second criterion, primary energy sources are called 'renewable' if their reserves do not decrease significantly in the time scale of its exploitation (such as hydroelectric, wind, solar, geothermal, tidal or the energy use of biomass); and "non-renewable" if they do (such as fossil fuels - coal, oil, natural gas - and nuclear energy).

Most commonly, the type of energy referred to is:

Power (physical), the rate of work; equivalent to an amount of energy consumed per unit of time

Electrical energy, the rate at which electrical energy is transferred through an electrical circuit; usually produced by electric generators or batteries

PowerSource may also refer to:

The power source can also refer to: A primary energy source, a form of energy found in nature that has not undergone any conversion or transformation process.

Energy carrier, or secondary energy, a substance or phenomenon that contains energy that can then be converted into other forms such as mechanical work or heat or to operate chemical or physical processes.

Fuel, a material that stores potential energy in forms that can be released and used for work. See Energy Development for an overview of primary and secondary energy or energy sources. or, often more specifically to an electrical power source:

A source of electrical energy.
