Petroleum remained the world's favorite energy source by a wide margin, fueling 39 percent of worldwide demand in 2000 according to the latest edition of the International Energy Annual. Coal held second place with 24 percent of the total, a retreat from 1991 when it provided more than one-quarter of the world's energy. Natural gas capped its decade-long advance with a robust gain over 1999, closing to within 1 percent of coal.

Consumption of hydroelectric and nuclear electric power grew by fits and starts during the 1990s but closed out the decade with an aggregate increase of 20 percent over 1991. Together, these two sources filled 13 percent of global energy demand in 2000.

Other primary energy sources (electric power from geothermal, solar, wind, and wood and waste generation) grew much faster than the rest of the energy sector, but still represent less than 1 percent of primary energy consumption.

Country Data
In 2000, three countries -- the United States, China, and Russia -- were the largest energy users with combined total consumption of 164 quadrillion British thermal units (Btu), or 41 percent of the global tally, about the same as the previous year. In 2000, consumption rose by about 2 percent in both the United States and Russia but declined 1 percent in China.

The United States was again the undisputed leader with one-quarter of global consumption in 2000, followed by China, which surged past Russia in 1994 to claim the second spot at 9 percent of global energy intake. Russian consumption, which had plummeted 27 percent between 1992 to 1997, continued to rebound and posted its third consecutive gain in 2000 to reach 7 percent of the world total.

Japan, the next largest energy consumer, accounted for about 5.5 percent of world demand in recent years, followed by Germany with 4 percent and Canada with 3 percent. India jumped from ninth position in 1991 to seventh in 2000 with a 57-percent increase to almost 13 quadrillion Btu, surpassing France and the United Kingdom.

Regional Information
In 2000, the energy deficit in North America widened to 19 quadrillion Btu as consumption continued to outpace production. The region's output barely budged while consumption rose 2.5 quadrillion Btu over 1999. Although supply in Western Europe grew at a faster rate than demand between 1991 and 2000, the region was still using 60 percent more energy than it produced at the end of the period. The energy deficit in Asia and Oceania increased from 16 quadrillion Btu in 1991 to 27 quadrillion Btu in 2000, as this region experienced the largest absolute increases in both consumption and production.

In 2000, the Middle East increased production by 4 quadrillion Btu, pushing the region's energy surplus to 40 quadrillion Btu. Throughout the past 10 years, the Eastern Europe and Former U.S.S.R. region was also a net provider of energy. The region's primary energy surplus increased from 6 quadrillion Btu in 1991 to 11 quadrillion Btu in 2000, with the largest gain occurring in 2000.

Other Information
In addition to energy consumption and production statistics, the International Energy Annual 2000 contains information about trade and reserves for petroleum, natural gas, and coal; crude oil refining capacity and electricity installed capacity by type; prices for selected crude oils and refined petroleum products in selected countries; world carbon dioxide emissions; and world population and gross domestic product statistics for 1991-2000.
