直到五十年代中期,联邦德国的煤炭出口与石油进口大体相抵,其能源供应基本自给自足。大约10年后,石油的输入猛增。到第一次石油危机的1973年,西德的一次能源烟煤和褐煤占到能源总供应的30％,石油达到55％,到六十年代中期,新露头角的天然气已占了能源市场贸易的10％,即使在后来能源需求下降时仍然不减,目前已占到一次能源消费量的15％。 Until the mid-fifties, the Federal Republic of Germany’s coal exports roughly offset its oil imports, and its energy supply was basically self-sufficient. About 10 years later, oil imports soared. By the first oil crisis In 1973, primary energy bituminous coal and lignite accounted for 30% of the total energy supply and oil reached 55%. By the mid-1960s, the new outcrop of natural gas accounted for 10% of the energy market trade. %, Even after the decline in energy demand did not diminish, now accounts for 15% of energy consumption.
