- Energy in Japan
Japan lacks significant domestic sources offossil energy exceptcoal and must import substantial amounts ofcrude oil ,natural gas , and other energy resources, includinguranium . In 1990 Japan's dependence onimport s forprimary energy stood at more than 84%, and the country had a total energy requirement of 428.2 million tons of petroleum equivalent.Energy use
Japan's rapid industrial growth since the end of
World War II doubled the nation's energy consumption every five years into the 1990s. During the 1960-72 period of accelerated growth, energy consumption grew much faster than GNP, doubling Japan's consumption of world energy. By 1976, with only 3% of the world's population, Japan was consuming 6% of global energy supplies.In 1990, consumption totalled 298 million tons: 46.7% of which was used by industry; 23.3% by the
transportation sector; 26.6% foragricultural ,residential , services, and other uses; and 3.3% for non-energy uses, such aslubricating oil orasphalt .JapanElectricity generation
In 1989 Japan was the world's third largest producer of electricity. About 75% of the available power was controlled by the ten major regional power utilities, of which
Tokyo Electric Power Company was the world's largest. Electricity rates in Japan were among the world's highest.Electrical power supply
The standard voltage at power outlets is 100V, but there are two frequencies in use, 50Hz and 60Hz (see [http://www.japan-guide.com/e/e2225.html Japanese electricity] ).
Utilities
In Japan, the electricity market is uniquely divided up into 10 regulated monopolies.
Energy supply
In 1950 coal supplied half of Japan's energy needs,
hydroelectricity one-third, and oil the rest. In 1988 oil provided Japan with 57.3% of energy needs, coal 18.1%, natural gas 10.1%,nuclear power 9.0%, hydroelectic power 4.6%,geothermal power 0.1%, and 1.3% came from other sources. By 2001 the contribution of oil had declined further to 50.2% of the total, with further rises in the use of nuclear power and natural gas.
