JAPAN
1. ENERGY, ECONOMIC AND ELECTRICITY INFORMATION
1.1. General Overview
Situated in the far east of Asia, Japan is subject to a monsoon climate in the Temperate Zones. Japan has four distinct seasons that affect changes in the demand for energy and electric power. There are two peaks in the annual fluctuation of Japan's electric power demand: one is a summer peak due to the use of air-conditioning (cooling), and the other is a winter peak due to the use of heating.
Table 1 shows Japan's total population, its density and its rate of increase.
Table 2 shows the Gross Domestic Product (GDP) in total, the growth rate, and
the GDP per sector. Table 3 shows the estimated energy reserves in Japan. Figures
1.1 and 1.2 present the primary energy supply and the final energy consumption.
The balance of energy production (supply) and energy consumption (demand) is
shown in Table 4.1. Table 4.1 also shows the import/export balance. Table 4.2
shows the end-use of energy consumption by sector.
A key feature of Japan's energy consumption (see Table 4.2) is that the industrial
sector accounts for the bulk of the total, with 45.9% (in FY2001), while the
residential and commercial sector is 29.3% and the transportation sector is
24.8%.
Japan's total primary energy supply (in FY2001) was 22,784 PJ. Japan still depends heavily on oil, even though its dependency has dramatically decreased from 77.4% in 1973 to 49.4% at present. The decline in oil dependency can be attributed mainly to the energy conservation efforts of Japanese industries and the development of alternative energy resources in Japan. In FY2001, Japan imported 99.8% of the oil consumed in Japan (87.9% of crude oil was imported from Middle Eastern countries).

to energy by multiplying the gross theoretical annual capability (World Energy
Council - 1998) by a factor of 10.
