In the United States, the shale-gas revolution, facilitated by the development of hydraulic fracturing (“fracking”), has brought prices to their lowest levels since natural gas gained prominence after the oil crises of the 1970s. With many more countries set to tap shale-gas reserves over the next decade, this downward trend will most likely continue, helping to lower the price of electricity generation further.
美国的页岩气革命在水力压裂法的推动下已经使天然气价格降到20世纪70年代石油危机天然气取得主导地位后的最低水平。未来十年随着更多国家着手开发页岩气储量，这种降价趋势极有可能将得以延续，并进一步降低发电价格。这也是极光能源研究所近期预测今后三十年电价显著下降的理由。
