An Investigation on energy consumption in Japan; Industry sector

Suzuki, Takayoshi*

Energy consumption in the industry sector, which is larger than that of the residential/commercial or transportation sector, occupies nearly 50% of final energy consumption in Japan. The industry sector has made an effort for energy conservation from an economical point of view. Now further effort is required also to cope with a global warning problem. This report summarizes the results of investigation on energy consumption, changes in energy intensity and development of energy conservation technologies including those common to the industries and recycling of wastes, focusing on energy intensive industries such as iron & steel and chemicals. Advanced energy conservation technologies or systems are being developed with a large and continuous effort in all industris, and recycling of wastes, e.g. waste plastics, has started in industry scale.
