On Wednesday, a fossil-fuel lobbying group called the Washington Coal Club awarded President Trump a trophy that named him the "Undisputed Champion of Clean, Beautiful Coal." Trump took advantage of the opportunity to take his latest shot at reviving the fortunes of the US's most polluting source of electricity: an executive order that would make the military buy it.
Coal is the second most expensive source of power for the US grid, eclipsed by gas, wind, solar, hydro—everything other than nuclear power. It also produces the most pollution, including particulates that damage human lungs, chemicals that contribute to acid rain, and coal ash that contains many toxic metals. It also emits the most carbon dioxide per unit of energy produced. Prior to Trump's return to office, the US grid had been rapidly moving away from its use, including during his first term.
Despite the long-standing Republican claims to support free markets, the second Trump administration has determined that the only way to keep coal viable is direct government intervention. Its initial attempts involved declaring an energy emergency and then using that to justify forcing coal plants slated for closure to continue operations. The emergency declaration relied on what appears to be a tenuous interpretation of the Federal Power Act, and the administration was already facing a lawsuit challenging these actions.
