Yesterday, flanked by a coal miners in hard hats, Trump signed four executive orders to restore their industry to its past glory. Given that coal is now the most expensive way to generate power other than nuclear, that’s going to be a heavy lift. Like many of Trump’s orders, these four are full of threats and bluster, but will have little immediate effect. These orders give the same impression as many executive orders -- that Something Important is Being Done -- but they are really more in the way of promises of future action.
