"An Obama administration is likely to be very aggressive in subsidizing and promoting alternatives, including a windfall tax on oil firms to support development of alternative energy; SunPower Corp. (NASDAQ: SPWR) is our pick to play an Obama victory," says Elliott Gue in The Energy Strategist.

"And SunPower recently won a contract with Florida-based utility FPL to build the largest photovoltaic plant in North America, a 25 megawatt utility-scale plant in DeSoto County, Florida.
