Slate: Coal is getting killed in the U.S. That's largely because its main customer, the electricity industry, is switching to fuels or sources that are either cheaper or cleaner (or both), like natural gas and renewables. In March, for example, coal accounted for only 24 percent of electricity generated down in the U.S.--that's down from 33 percent in March 2015 and from 41 percent in March 2014. So far this year, U.S. coal production is just two-thirds of what is was last year.
Coal is being massacred...
