As part of a series of studies on the institutional and technical aspects of cogeneration and district heating, a net energy analysis has been performed on three systems for providing space heating, space cooling, domestic hot water, and domestic electricity for an idealized community located in a climate similar to that of Minneapolis, Minnesota. The three systems are an all-electric system, a gas-electric system, and a cogeneration-district heating system. The capital and operating energy costs were determined, and a life cycle energy cost analysis was performed. Results of the life cycle energy cost analysis show that the cogeneration-district heating system consumes about half as much primary energy as the all-electric system and four-fifths as much primary energy as the gas-electric system. In the gas-electric and all-electric systems, coal provides 39% and 70%, respectively, of the operating energy. Coal provides 76% of the annual operating energy for the district heating system. Because the district heating system consumes primarily coal rather than scarce and more expensive crude oil and natural gas, it depends less on foreign sources of fossil fuel.
