‘Barack Obama’s pledge to cut carbon emissions has not stopped North Antelope Rochelle mine in Wyoming. In fact, production is booming – and climate change is off the agenda. The Guardian’s Suzanne Goldenberg gets a rare look inside the biggest coal mine in the world (10 November 2014)’.
A couple of years ago, the U.S. got about half of its energy from coal-powered plants, but now ” America gets about 40% of its electricity from coal . . . According to the Energy Information Administration (EIA), its use of coal for energy rose 4.8% last year, in part because of the Arctic blasts of the polar vortex. Carbon dioxide emissions from energy registered one of their steepest rises in the last quarter century”.
