事实上，根据国际能源机构的近期预测，打破常规的碳氢化合物（特别是页岩油气）革命到2020年将使美国成为世界最大产油国，而到2030年则将成为最大产能国，由此产生的全球反响将不容小觑。
Indeed, the revolution in non-conventional hydrocarbons, particularly shale gas and oil, which the International Energy Agency recently predicted would make the US the world’s largest oil producer by 2020, and the top energy producer overall by 2030, will have enormous global repercussions.
