A breath of fresh air for your portfolio

Newsday reports that wind technology has become an investing hot spot as utilities look for alternatives to fossil fuel to generate power.

Can wind stocks still power your portfolio? Many investment advisers say yes. They note that Warren Buffett and T Boone Pickens, two of the world's best investors, are investing heavily in wind farms.

CNBC stock picker Jim Cramer says Trinity Industries, Woodward Governor and Owens Corning are positioned to reap the rewards of wind technology, because they make or install equipment needed to turn wind into electricity.

Cramer also picks Broadwind, but be aware the company has never turned a profit.

Motley Fool likes Market Vector Alternative Energy, an exchange-traded fund that holds several wind power stocks in its portfolio.

Also understand there may be an ill wind blowing. Business Week says wind generation may have already reached maturity, meaning the stocks could have little room to go up in price.

However, the expert investors may be right, as many governments are still promoting clean energy, including in the UK.

Bloomberg reports the UK government may provide extra subsidies for small-scale electricity generation to reduce emissions of carbon dioxide and improve supply security.
