In electricity generation, an '''electrical generator''' is a device that converts mechanical energy to electrical energy, generally using electromagnetic induction. The reverse conversion of electrical energy into mechanical energy is done by a motor, and motors and generators have many similarities. The source of mechanical energy may be a reciprocating or turbine steam engine, water falling through a turbine or waterwheel, an internal combustion engine, a wind turbine, a hand crank, the sun or solar energy, compressed air or any other source of mechanical energy.

A electricity generator, electrical generator, engine-generator, generator-set or gen-set is a device that converts mechanical energy into electrical energy (electricity), generally using electromagnetic induction (by means of a alternator or dynamo). The source of the mechanical energy used to generate the electricity may be a heat, pneumatic or electric motor, a wind turbine, human or animal labour, the sun, or the ocean.

The reverse conversion of electrical energy into mechanical energy is done by a motor. A heat engine and alternator/dynamo assembly that is also used to provide heat (for space heating) is called a "combined heat and power system".

A wood gas generator with thermal energy recovery (via a stirling motor) can allow up to 70% of the thermal energy of the burning of wood to be used. A system like this works by using 2 separate electricity generators (1 on the IC-engine, another on the Stirling engine)
