DISTRIBUTED GENERATION
Distributed generation also called distributed energy or Onsite Generation, is a new trend in the generation of heat and electrical power. The Distributed Energy Resources (DER) concept permits "consumers" who are generating heat or electricity for their own needs to send surplus electrical power back into the power grid also know as net metering or share excess heat via a distributed heating grid. Distributed generation systems with Combined Heat and Power (CHP) systems can be very efficient, using up to 90% of the fuel they consume. CHP can also save a lot of money and fuel. Estimates are that CHP has the potential to reduce the energy usage of the USA by up to 40%. The CHP system installed at Saddleback Community College in San Diego , CA is estimated to produced a monetary savings of 11.2 million dollars over the next 15 years.
