Is Clean Coal Ready for Primetime?

Do you remember BP's Beyond Petroleum ad campaign in the 2000s? As a writer at Adweeknoted in 2010 (in the wake of BP's disastrous Gulf of Mexico oil spill), the campaign "has always been borderline ludicrous, positioning the oil company as essentially anti-oil (or post-oil)." Well, if that was ludicrous, what do we call the idea of clean coal, which the coal lobby has successfully propagated in recent years? Over at Slate, I have a new piece that argues, "Clean coal is no joke."
