President Obama's climate speech on Tuesday was grandiose even for him, but its surreal nature was its particular hallmark. Some 12 million Americans still can't find work, real wages have fallen for five years, three-fourths of Americans now live paycheck to check, and the economy continues to plod along four years into a quasi-recovery. But there was the President in tony Georgetown, threatening more energy taxes and mandates that will ensure fewer jobs, still lower incomes and slower growth.

Mr. Obama's "climate action plan" adds up to one of the most extensive reorganizations of the U.S. economy since the 1930s, imposed through administrative fiat and raw executive power. He wants to reduce greenhouse gas emissions by 17% by 2020, but over his 6,500-word address he articulated no such goal for the unemployment rate or GDP.

The plan covers everything from new efficiency standards for home appliances to new fuel mileage rules for heavy-duty trucks to new subsidies for wind farms, but the most consequential changes would slam the U.S. electric industry. These plants, coal-fired power in particular, account for about a third of domestic greenhouse gases.

Last year the Environmental Protection Agency released "new source performance standard" regulations that are effectively a moratorium on new coal plants. The EPA denied that similar rules would ever apply to the existing fleet, or even that they were working up such rules. Now Mr. Obama will unleash his carbon central planners on current plants.

Coal accounted for more than half of U.S. electric generation as recently as 2008 but plunged to a mere 37% in 2012. In part this tumble has been due to cheap natural gas, but now the EPA will finish the job and take coal to 0%.
