Energy Conservation Technologies and Expectation in Japan

Energy conservation technologies are primary measures against the global environmental issues. Since ‘Oil Shock’ in the middle of 1970s, Japanese industries have endeavored to increase energy efficiency that has resulted in a decrease in the production cost. This article describes the transition of energy consumption in Japan, outline of the energy conservation laws, and energy conservation technology developments for the industrial sector, for the commercial/residential sector, and the transportation sector. Five development themes on energy conservation of the national technological strategies are designated to be promoted by the year 2030. As one of the designated topics in the commercial sector, some development results of a national project on HEMS (Home Energy Management System) are described. Detail technologies in major fields are shown in the following papers. Copyright © 2008 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.     

Japan's Energy Conservation Initiatives: Highlighting the Energy Conservation Policy

This article introduces the energy conservation activities in Japan, focusing on the energy conservation policy. The energy conservation activities in Japan started with the two oil shocks in the 1970s. Development of relevant laws and promotion of subsidy measures were started in this period as well. The consciousness for the energy conservation had been once weakened in the late 1980s through the time of bubble years, but in response to the internationally up‐streaming discussions on global environmental problems in the late 1980s, the importance of the energy conservation was called for again in Japan. Under these circumstances, the final energy consumption in Japan after the oil shocks has leveled off in the industrial sector thanks to their endeavor for energy conservation, but in the commercial/residential sector and transportation sector, it has been continuously increasing. Under these conditions and more and more severe energy situations such as the steep rise of crude oil price, the Ministry of Economy, Trade and Industry established the ‘New National Energy Strategy’ in May 2006, in which a new energy conservation target was set forth in that the energy efficiency would be improved by 30% or more by 2030. Responding to this target, the Agency for Natural Resources and Energy summarized and published the ‘Energy Conservation Technology Strategy (Interim Report)’ in September 2006.

Energy Conservation in Urban Areas

This article outlines the energy conservation measures in the civilian sector from a few different viewpoint regarding energy conservation in cities. First, the energy consumption trends in the business and residential sectors are discussed, focusing the importance of energy conservation measures in applications such as home heating, water heating and specific power demand. Second, as a measure to reduce energy demand itself, energy conservation by way of applying heat insulating materials to buildings and changing the life style of residents is considered. And from the viewpoint of improving the energy system efficiency, additionally discussed here are the measures to improve the efficiency of each energy equipment such as air‐conditioners and co‐generation equipment, and the characteristics of District heating and cooling systems such as the local energy infrastructures. Lastly, from the knowledge obtained through model analyses by the authors, a scheme is recommended that would be one of the most efficient city‐energy schemes where the energy systems including heat pumps, co‐generators or equipment using solar power are utilized for their best‐suited applications for business and residential customers.
