'''Electricity generation''' is the process of generating [[electric power]] from sources of [[primary energy]]. For [[electric utility|utilities]] in the [[electric power industry]], it is the stage prior to its [[Electricity delivery|delivery]] ([[Electric power transmission|transmission]], [[Electric power distribution|distribution]], etc.) to end users or its [[Grid energy storage|storage]], using for example, the [[Pumped-storage hydroelectricity|pumped-storage]] method.

Consumable electricity is not freely available in nature, so it must be "produced", transforming other forms of energy to electricity. Production is carried out in [[power station]]s, also called "power plants". Electricity is most often generated at a power plant by [[electromechanical]] [[electric generator|generators]], primarily driven by [[heat engine]]s fueled by [[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]]. There are exotic and speculative methods to recover energy, such as proposed [[fusion reactor]] designs which aim to directly extract energy from intense magnetic fields generated by fast-moving charged particles generated by the fusion reaction (see [[magnetohydrodynamics]]).<!-- Helion Energy in particular, but it's a general physical concept, and I see no reason to pump their IPO in specific terms -->
