"Around the globe, wind-generating capacity has been expanding at a rapid 30% clip in recent years," notes value investor Nathan Slaughter, who adds, "And 2008 is already shaping up to be even better."

The editor of Half-Priced Stocks looks at industrial product firm Trinity Industries (NYSE: TRN), explaining, "The company's most promising division is involved in the production of structural wind towers." Here's the advisor's of the latest addition to his "deep-discount' model portfolio.

"Led by states such as Texas and California, wind farms around the country will generate almost 50 billion kilowatt hours of electricity this year. Of course, the U.S. is still playing catch-up with many other regions.

"In fact, countries such as Spain, Portugal and Denmark all rely on wind farms for as much as one-quarter of their total power needs. Across Europe, wind turbines will account for roughly one-third of all new generating capacity installed over the next few years and could provide electricity for 90 million people by 2010.

"The outlook is even brighter in many booming, energy-hungry Asian markets. In China, installed wind power capacity surged +130% last year and will reportedly supply a great deal of the electricity needed for the upcoming 2008 Beijing Olympic Games.

"Thanks to the great strides in engineering, wind turbine output has increased by a factor of ten (or higher in some cases) over the past decade.
