Power source information

A power source is a source of power. Most commonly the type of power referred to is:

Power (physics), the rate of doing work; equivalent to an amount of energy consumed per unit time
- Electric power, the rate at which electrical energy is transferred by an electric circuit; usually produced by electric generators or batteries

Power source may correspondingly refer to:

A source of primary energy, an energy form found in nature that has not been subjected to any conversion or transformation process
Energy carrier, or secondary energy, a substance or phenomenon that contains energy that can be later converted to 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 practicably released and used for work
- See Energy development for an overview of primary and secondary energy or power sources

or, often more specifically to an electric power source:

Some conversion devices are sometimes called a "power source":

Engine, a machine designed to convert energy into useful mechanical motion
Power supply, an electrical device that supplies electric energy to an electrical load, by converting one form of electrical energy to another
