President Donald Trump’s effort to put coal miners back to work stumbled in most coal producing states last year, even as overall employment in the downtrodden sector grew modestly, according to preliminary government data obtained by Reuters. The effort has had little impact on domestic demand for coal so far, with U.S. utilities still shutting coal-fired power plants and shifting to cheaper natural gas - moving toward a lower carbon future despite the direction the White House is plotting under Trump. Unreleased full-year coal employment data from the Mining Health and Safety Administration shows total U.S. coal mining jobs grew by 771 to 54,819 during Trump’s first year in office, led by Central Appalachian states like West Virginia, Virginia, and Pennsylvania - where coal companies have opened a handful of new mining areas for shipment overseas.
