美国新能源发展,以及页岩气等替代能源的爆发式增长,使美国逐步摆脱对石油的过度依赖,美国能源自给率逐渐提高,2011年达到81.4%,彻底扭转了能源自给率下滑的态势。
The development of new energy sources in the United States and the explosive growth of alternative energy sources such as shale gas have gradually removed the United States from over-dependence on oil. The self-sufficiency rate of energy in the United States has gradually increased and reached 81.4% in 2011, completely reversing the declining energy self-sufficiency rate.
