US Coal Exports Declined 23 Percent in 2015
The U.S. remains a net exporter of coal, exporting 74 million short tons (MMst) and importing 11 MMst in 2015, according to information from the U.S. Energy Information Administration on March 7.

Coal exports fell for the third consecutive year in 2015, ending the year 23 MMst lower than in 2014 and more than 50 MMst less than the record volume of coal exported in 2012.

Slower growth in world coal demand, lower international coal prices and higher coal output in other coal-exporting countries contributed to the decline in U.S. coal exports.

Ohio Takes in More Fracking Wastewater
The amount of fracking wastewater pumped underground in Ohio increased by more than 15 percent in 2015, even as shale drilling has slowed nationwide, according to data from the Ohio Department of Natural Resources.

Ohio took in nearly 29 million barrels of fracking wastewater in 2015, about 4 million barrels more than in 2014.

Ohio is situated to accept wastewater from states that don’t allow injection waste wells and has more than 200 injection wells. Fewer than 10 have been approved in Pennsylvania, where much of the fracking boom has taken place. West Virginia has about 60.

Ohio typically takes more fracking wastewater from outside Ohio than inside. However, last year about 55 percent of the wastewater that ended up in Ohio injection wells came from Ohio, the data shows.
