An energy generation process (also referred to as combined heat and power) common at pulp and paper mills where electricity and heat are simultaneously produced from a common fuel source. In this process, a fuel source is combusted to heat water to produce high temperature and pressure steam. The steam is used to turn a turbine to produce electrical energy and then the excess heat is used for industrial processes and/or space heating. Cogeneration systems are very efficient because they capture and use energy that otherwise would be wasted.
