    OverviewHistoryMethods of generationEconomicsGenerating equipmentProductionEnvironmental concernsSee also

    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" (that is, transforming other forms of energy to electricity). Production is carried out in power

    Coal burnt as a solid fuel in coal power stations to generate electricity is called thermal coal. Coal is also used to produce very high temperatures through combustion. Early deaths due to air pollution have been estimated at 200 per GW-year, however they may be higher around power plants where scrubbers are not used or lower if they are far from cities. Efforts around the world to reduce the ...

  • Powering A Generation: Generating Electricity

    A special type of hydro-power is called "Pumped Storage". Some non-hydro plants can take advantage of periods of low demand (and low costs) by pumping water into a reservoir. When demand rises, some of this water is channeled through a hydro-turbine to generate electricity. Since "peak-load" generating units (used to meet temporary demand surges), are generally more expensive to run than "base ...
