Definition: Electricity generation
From Open Energy Information
The process of producing electric energy or the amount of electric energy produced by transforming other forms of energy into electrical energy; commonly expressed in kilowatt-hours (kWh) or megawatt-hours (MWh).
- Electricity generation is the process of generating electric power from sources of primary energy. For utilities in the electric power industry, it is the stage prior to its delivery to end users (transmission, distribution, etc.) or its storage (using, for example, the pumped-storage method). A characteristic of electricity is that it is not freely available in nature in large amounts, so it must be produced. Production is carried out in power stations (also called "power plants"). Electricity is most often generated at a power plant by electromechanical generators, primarily driven by heat engines 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.
- Electricity generation includes all technologies that turn some form of energy into useful electric energy. Electricity is a form of energy that has magnetic, radiant and chemical effects. Electric current is created by a flow of electrons.
