New Systems of Energy

摘要

JAPAN HAS FEW energy resources of its own, and the two oil crises of the 1970s emphasized the need for energy conservation. Ever since then, Japan has actively promoted energy efficiency with its energy conservation promotion measures. As a result of these measures, by 1998 Japanese energy efficiency in terms of GDP had improved by more than 30 percent compared to the time of the first oil crisis in 1974. Japan's energy efficiency has reached the highest standards in the world however, overall energy consumption has been increasing since the beginning of the 1980s.Industry consumes roughly one-half of Japan's energy, while the remainder is divided about evenly between transportation on the one had and commercial and residential use on the other. Even though industrial output is still increasing, energy consumption levels has shown very little change. This is the result of the years of conservation efforts since the oil crises. Meanwhile, consumption of energy for transportation as well as for residential and commercial uses continues to climb. Most noticeably, the spread of computers has led to greater electricity use.
