Cramer blessed the stock, saying that as Massachusetts' largest utility, it has a great dividend yield and should be immune to proposed carbon legislation. Cramer told another viewer that he'd take some profits in Clean Energy Fuels ( CLNE) and Westport Innovations ( WPRT) after their big runs, but he's still bullish on both companies.
