美国在近代一百多年的经济发展中,得益于本国和世界充足、廉价的能源供应。直到1973年发生石油危机之前,美国一直处于“能源天堂”之中,从未被能源短缺困扰过。1850年美国能源消费折合标准煤仅为1.07亿吨,1900年为4.36亿,1950年为15.97亿吨,1975年为32.27亿吨。1850年到1950年一百年间,美国能源消费增长了14倍,平均每年增加2.7％。
In the economic development of the United States in the past more than one hundred years, the United States has benefited from the abundant and cheap energy supply in the country and the world. Until the oil crisis in 1973, the United States had been in an “energy paradise,” never being plagued by an energy shortage. In 1850, the energy consumption of the United States was equivalent to only 107 million tons of standard coal, 436 million in 1900, 1.597 billion tons in 1950, and 3.227 billion tons in 1975. In the one hundred years from 1850 to 1950, the U.S. energy consumption increased by 14 times, an average annual increase of 2.7%.
