Cogeneration is a highly efficient means of generating heat and electric power at the
same time from the same energy source. Displacing fossil fuel combustion with heat
that would normally be wasted in the process of power generation, it reaches
efficiencies that can triple, or even quadruple conventional power generation.
Cogeneration equipment can be fired by fuels other than natural gas. There are
installations in operation that use wood, agricultural waste, peat moss, and a wide
variety of other fuels, depending on local availability.
The environmental implications of cogeneration stem not just from its inherent
efficiency, but also from its decentralized character. Because it is impractical to
transport heat over any distance, cogeneration equipment must be located physically
close to its heat user. Cogeneration plants tend to be built smaller, and owned and
operated by smaller and more localized companies than simple cycle power plants. As
a general rule, they are also built closer to populated areas, which causes them to be held to higher environmental standards. In northern Europe, and increasingly in North
America, cogeneration is at the heart of district heating and cooling systems. District
heating combined with cogeneration has the potential to reduce human greenhouse
gas emissions by more than any other technology except public transit.
