Abstract
Cogeneration systems in business and commercial sector and residential sector compete with other dispersed energy systems such as solar energy utilization systems and heat pump systems in terms of the effectiveness of reducing CO2 emission, primary energy and cost. The author tries to evaluate the competitiveness of CGS by utilizing a multi-objective energy system planning model for urban area. CGS is found to be effective within a certain range of CO2-cost and primary energy-cost tradeoffs.
