The U.S. produced 1 billion tons of coal in 2014, "the large majority of which was consumed to generate electricity right here at home," Mooney reports. "In 2015 that dipped to 895.4 million short tons, a drop of more than 100 million tons in just one year. The drop, incidentally, was considerably more than EIA itself had forecast around this time a year ago, when the agency had expected a decline to 926 million tons."
Timothy Hess, an analyst with the EIA’s Short Term Energy Outlook, told the Post: "The major contributor of lower coal production in the most recent STEO compared with a year ago is the increase in natural gas used in the electric-power sector, mainly because of lower natural-gas prices. In the April 2015 STEO, EIA forecast natural gas price at Henry Hub [the standard measuring point for U.S. gas] to average $3.45/million British thermal units in 2016. In the April 2016 STEO, EIA forecast the natural gas price at Henry Hub to average $2.18/mBtu in 2016. This drop in forecast price makes it more economic to run gas-fired generating units and reduced generation at some coal-fired units. The reduction in coal used for electric generation contributes to lower coal production." (Read more)
