The U.S. energy revolution has passed a milestone, if new data is correct. By the end of August, federal projections indicate, America will become a net exporter of natural gas, and remain so well into the future.

In every month of 2018, American natural gas producers will post a large and growing export surplus. As LNG terminals are built, the nation’s capacity to export liquefied natural gas is expected to triple by 2019, to more than 9 billion cubic feet a day.
