*Electricity generation* is the process of generating electrical power from
other sources of primary energy.

The fundamental principles of electricity generation were discovered during
the 1820s and early 1830s by the British scientist Michael Faraday. His
basic method is still used today: electricity is generated by the movement
of a loop of wire, or disc of copper between the poles of a magnet.^[1]

For electric utilities, it is the first process in the delivery of
electricity to consumers. The other processes, electricity transmission,
distribution, and electrical power storage and recovery using
pumped-storage methods are normally carried out by the electric power
industry.

Electricity is most often generated at a power station by electromechanical
generators, primarily driven by heat engines fueled by chemical combustion
or nuclear fission but also by other means such as the kinetic energy of
flowing water and wind. Other energy sources include solar photovoltaics
and geothermal power.
