Although energy consumption in the industry sector has almost been stable, energy consumption in the transportation (passenger and freight) sector has increased after the oil crisis. The increase of energy consumption in passenger sector can be attributed to the increase in transportation by private passenger vehicles; while the increase in freight sector was due to the modal shift to trucks. Among transportation methods, automobiles are now dominant in terms of energy consumption and also in terms of amount of transportation. Therefore implementing energy conservation measures relating to automobiles is very important in order to suppress the energy consumption in transportation. This report summarizes the results of investigation on energy conservation measures, especially relevant to automobiles. The investigation has shown that most promising and effective technologies or measures are promoting market penetration of vehicles satisfying "top runner standard", development and employment of hybrid vehicles, and introduction of vehicles with "idling-stop" systems.

Energy consumption in the residential and commercial sector has increased substantially after the oil crisis, although energy consumption in the industry sector has been almost stable, and is expected to increase further with continued change of lifestyle seeking more convenience and comfort. This report summarizes the results of investigation on energy consumption, energy efficiency, prices etc. of energy intensive devices such as electric refrigerator, air conditioner, stove and gas table used in the residential and commercial sector. Also investigated are new promising technologies or systems under development. The efficiency of some technologies, e.g. electric refrigerator, has improved remarkably, and new technologies such as heat pump water heating systems and small capacity residential cogeneration systems are recently developed.

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.
