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 (transmission, distribution, etc.) to end users or its storage, using for example, the pumped-storage method.
Power generation describes how electrical power is converted from different energy sources at power plants. Understanding how we generate and transmit power helps us think about electronics and the electrical devices you probably use every day.
Most U.S. and world electricity generation is from electric power plants that use a turbine to drive electricity generators. In a turbine generator, a moving fluid—water, steam, combustion gases, or air—pushes a series of blades mounted on a rotor shaft.
Power Generation Definition: Electrical power generation is the process of converting different forms of energy into electrical energy. Renewable Sources: Renewable sources like solar, wind, hydro, tidal, and biomass are environmentally friendly and unlimited.
Generation: a measure of electricity produced over time. Most electric power plants use some of the electricity they produce to operate the power plant. Net generation excludes the electricity used to operate the power plant.
Electricity generation from cleaner renewable energy sources, particularly wind and solar PV, is rapidly increasing. For more information about electricity, visit our The Grid: Electricity Transmission, Industry, and Markets and Decarbonization of the Electric Power Sector pages.
Electricity is an energy currency, rather than an energy source, which means that electrical generation needs to start from a primary energy source like a fuel or a primary energy flow. These fuels and flows are usually turned into electric current which transmits electric power to the grid.
