Abstract: Cogeneration or combined heat and power (CHP) is expected to be an effective measure in coping with the global warming problem. In this study, the authors present the results of a survey on the state of cogeneration in the OECD (Organisation for Economic Cooperation and development) and East European countries, and then investigate the effectiveness of CHP via model analysis on some particular countries. The simulation results show that an energy saving of about 10% is estimated for fully installed cogeneration in the commercial/residential sector, on average. However, the model analysis reveals that energy conversion efficiency is declining in almost all countries due to electrification. The analysis of the effectiveness of cogeneration in six countries, from the viewpoints of energy conservation and carbon dioxide reduction, shows that the results, of estimation on these points are relatively small in Japan and therefore some other policy measures than cogeneration are required to achieve greater reductions in energy consumption in the commercial/residential sector.
