The clean and alternative energy industries will be the site of a major showdown between political parties this year. Energy was a major focus in Obama's State of the Union speech, in which he laid out a goal to have 80% of the country's electricity come from clean energy by 2035. The PowerShares Wilderhill Clean Energy Portfolio ( PBW) will allow conservative investors to tap into a diverse collection of companies from various corners of the clean energy spectrum. Single sector funds, however, may prove attractive for more risk tolerant investors seeking exposure to individual pockets of the alternative energy industry. Some of the funds that will be influenced as debate rages over the nation's energy future will include the Guggenheim Solar Energy ETF ( TAN), First Trust ISE Global Wind Energy Index Fund ( FAN) and the Market Vectors Uranium + Nuclear Energy ETF ( NLR).
