5 Best Clean Energy Stocks To Buy Right Now

Exchange-traded funds offer a convenient way to invest in sectors or niches that interest you. If you'd like to add some clean-energy-related stocks to your portfolio, the PowerShares WilderHill Clean Energy Portfolio ETF (NYSEMKT: PBW  ) could save you a lot of trouble. Instead of trying to figure out which companies will perform best, you can use this ETF to invest in lots of them simultaneously.

The basics
ETFs often sport lower expense ratios than their mutual fund cousins. The PowerShares ETF's expense ratio -- its annual fee -- is 0.70%. The fund is fairly small, too, so if you're thinking of buying, beware of possibly large spreads between its bid and ask prices. Consider using a limit order if you want to buy in.

This ETF has performed�terribly, significantly underperforming the world market over the past three and five years. But the future counts more than the past, and it's been a rough few years for the entire solar energy industry, among others. And, as with most investments, of course, we can't expect outstanding performances in every quarter or year. Investors with conviction need to wait for their holdings to deliver. Indeed, stocks that have fallen sharply are sometimes great bargains.
