“I’d be OK if there were never any more coal,” says retiring Xcel Energy CEO Dick Kelly, who invested more than $1 billion in Pueblo's coal-fired Comanche 3 power plant. Leslie Glustrom of Boulder-based Clean Energy Action puts the interview “in the vein of ‘I can't believe I ate the whole thing.’ Burritos are only $3 mistakes and the indigestion lasts for a day. Coal plants are $1 billion mistakes and the ‘indigestion’ lasts for decades.”
