Wind power is the conversion of wind energy into electricity using turbines.  Wind is gaining worldwide popularity as a large scale clean energy source.  Currently, wind power provides only 1.5% of global energy consumption. But the potential for growth is astonishing.

Clean energy ETFs became hugely popular in 2007. But they’ve been taking a beating since this August, when crude oil prices began to fall from their year highs.

Nevertheless, Jim Stanton says alternative energy — and the wind-energy market in particular — has a big future. Wind energy is already the second largest source of new power generation in the US, and it now has the backing of the much-hyped Pickens Plan.

Jim says two clean-energy ETFs that look undervalued right now are PBW and GEX. He also recommends FAN for a more wind-specific ETF.
