今年全年美国天然气发电量首次超过燃煤发电量

　　据道琼斯12月22日消息，美国能源信息署（EIA）表示，今年全年是美国天然气发电量高于燃煤发电量的第一年。今年美国约34%的电力来自于天然气发电，而燃煤发电量为30%，而去年均为33%。页岩气的繁荣导致美国天然气供应充裕而且廉价，这是导致天然气发电量首次超过燃煤发电量的主要因素。过去十年间，美国发电厂的天然气平均燃料收据成本已经大幅下降，而煤炭平均燃料收据成本出现增加。此外环保法规和风力、太阳能和其他可再生能源发电也抑制了燃煤发电量。

　　Natural Gas Dominates Coal for First Full Year

　　This year is the first full year during which more power will be generated with natural gas than coal, the Energy Information Administration says. About 34% of this years power was likely fueled with natural gas, while 30% was fueled with coal, compared to 33% for each fuel in 2015. The primary driver is the shale-gas boom, which is making gas cheap and plentiful. Average fuel receipt costs at power plants over the past 10 years have plunged for gas and increased for coal. Environmental regulations and the growth of wind, solar and other renewable power generation are also keeping a lid on coal-fired power generation.
