President Trump's "America First" energy plan makes clear that the White House is committed to "reviving" the country's long-suffering coal industry.It's part of Trump's effort to live up to his campaign pledge to coal miners, whom he has told: "Get ready, because you're going to be working your asses off."As soon as this week, Trump could back up that campaign talk with real action. His energy plan, which appeared on WhiteHouse.gov just minutes after President Obama stepped down, promises to eliminate regulations that have been "harmful" for coal and other energy industries.For instance, observers believe Trump could swiftly issue an executive order lifting the Obama administration's moratorium on coal leasing of federal lands.Despite Trump's best intentions and regulation-busting actions, experts don't believe they will be enough to save coal.That's because coal has a fierce competitor in the form of natural gas. It's cheap, it's clean and there's a ton of it in the U.S. Plus, Trump himself supports expanded drilling of U.S. shale, the chief source of the boom in natural gas."The coal jobs aren't coming back," said James Van Nostrand, director of the Center for Energy and Sustainable Development at West Virginia University College of Law.
