Please forgive me, but when people are betting to win $5,000 a week for " Beat The Street," and they are wagering heavily on solar portfolios, I have to speak up for wind, which is much more explosive and happening much more quickly.

First, Sanford Bernstein put out a fabulous report today about alternative energy that waxed wonderfully about wind and a little less wonderfully about solar. The latter isn't as loved, because the average selling price of solar is too high vs. the dirty competition, and it needs to cut its average selling price. As much as I think First Solar ( FSLR) is -- to quote Randy Jackson -- THE BOMB, I see the ASPs coming down there, too. They can make it up in volume. But that said, wind's price is so competitive that it can go higher and still beat dirty fuels.

Two guys I respect, Warren Buffett (although I love Dougie's rap on him!) and T. Boone Pickens, are both making huge splashes with wind. They are snapping up GE ( GE) turbines left and right; if you recall, Buffett said he had to call in favors to get turbines, that's how back-ordered they are.

That's fabulous for the following game ideas: Trinity ( TRN), for the actual turbines; Woodward Governor ( WGOV) -- profiled last night on "Mad Money" -- for the transmission and turbine innards; Owens Corning ( OC) for the fiberglass wind blades; and Quanta ( PWR) for installation. Any of these makes more sense than anything but First Solar.

Oh, and let's not forget the thinly traded but explosive play, Broadwind ( BWEN), the purest play on it. (I know Vestas is pure, but I don't care for it). BWEN is the hottest of them all and a great contest selection even up here.

I want you to learn these stories. As I said in my book Real Money, a rotisserie league is the best way to learn. Check these out and maybe play them in the game next week.

The worst that could happen is that you learn the best alternative energy theme for 2009.
