"The 'clean coal' campaign was always more PR than reality — currently there's no economical way to capture and sequester carbon emissions from coal, and many experts doubt there ever will be. But now the idea of clean coal might be truly dead, buried beneath the 1.1 billion gallons of water mixed with toxic coal ash that on Dec. 22 burst through a dike next to the Kingston coal plant in the Tennessee Valley and blanketed several hundred acres of land, destroying nearby houses. The accident — which released 100 times more waste than the Exxon Valdez disaster — has polluted the waterways of Harriman, Tenn., with potentially dangerous levels of toxic metals like arsenic and mercury, and left much of the town uninhabitable."
