Powershares Wilderhill Clean Energy Portfolio (NYSEArca: PBW)

Current price: Around $6.50

YTD Performance: Up 50%

Comment: For just $4.25 in January, investors could have gotten in on PBW, which should be noted has almost $220 million in assets under management.  And for the price of a latte, PBW has delivered much, much more than the fleeting satisfaction of pricey coffee drinks. Clean energy ETFs have been stellar performers this year and PBW has, until recently, benefited from small allocations to Elon Musk’s companies:  SolarCity (NasdaqGM: SCTY) and Tesla (NasdaqGM: TSLA).
