Europe doesn’t want as much coal anymore, and that’s lowering U.S. exports, according to the U.S. Energy Information Administration.

Europe’s sudden, unexpected thirst for U.S. coal had been a boon to the industry in recent years. But that’s now dwindling and, coupled with greater competition from Australia and Indonesia, has pushed U.S. exports down 16 percent over the first six months of this year compared with the same period in 2013.
