摘要

Most of the world's energy supply is based on crude oil, natural gas and coal. In 2005, 87 percent of the world's needs (not counting biomass) were covered by these fossil fuels. Crude oil accounted for 36 percent, hard coal 25 percent, lignite 3 percent and natural gas 23 percent. For future energy supplies, too, the distribution and extent of the reserves of fossil energy feedstocks will be crucial. - Reserves are spread very unevenly across the globe. In the case of crude oil, conventional reserves are mainly concentrated on the Middle East and, in natural gas, on a region stretching from the Middle East to the CIS. By contrast, hard-coal and lignite deposits are widely scattered in geographic terms. The same is true of uranium. -The degree of exploration of deposits of the particularly scarce commodities oil and gas is higher globally than is true of coal and uranium deposits. Worldwide, no new finds of very large hydrocarbon deposits can be expected in future. This bottleneck situation permits assessments to be made of the future course of the world annual production of gas and oil using the depletion mid-point (DMP). -Very volatile oil and gas prices that will rise in the long term must be expected due to the focus of a large part of the reserves of crude oil and natural gas on politically unstable regions and to there being fairly low production-capacity buffers. By contrast, in terms of reserves, there is relaxation potential for the prices of hard coal, lignite and uranium.
