Cogeneration

Heating and Cooling

Cogeneration, also called combined heat and power, is the use of a heat engine or power station to generate electricity and useful heat at the same time. Rather than discarding the waste heat that a conventional power plant releases to the environment, a cogeneration system captures it for uses such as space heating or industrial process heat, so a single fuel input serves two purposes at once.

  • Cogeneration, History section, Pearl Street Station sentence
    Perhaps the first modern use of energy recycling was done by Thomas Edison. His 1882 Pearl Street Station, the world's first commercial power plant, was a combined heat and power plant, producing both electricity and thermal energy while using waste heat to warm neighboring buildings.
