Abstract
This survey was conducted in Kobe households to estimate the reduction in primary energy consumption and carbon dioxide emissions by introducing a micro fuel cell heat and power generation system. As a result, Even in the least effective month (in August), the primary energy consumption and carbon dioxide emissions has decreased by 13 percent thanks to the introduction of the system. Further, the reduction of annual carbon dioxide emissions are calculated and the price of the carbon credit are imported based on J-VER Scheme. The price of the carbon credit is equivalent or more than the subsidized cost of introducing the system. This promotion should be effective in reducing carbon dioxide emissions.
