A source of electrical energy
- Electricity generation, the process of generating electric power from other sources of primary energy
  - Power station, an industrial facility for the generation of electric power
  - Electric generator, a device that converts mechanical energy to electrical energy for use in an external circuit
Engine, a machine designed to convert energy into useful mechanical motion
Fuel, a material that stores potential energy in forms that can be practicably released and used for work
Mains electricity or household power, the general-purpose alternating-current (AC) electric power supply
- AC power plugs and sockets, devices that allow electrically operated equipment to be connected to the primary alternating current (AC) power supply in a building
