Billionaire Texas oil man makes big bets on wind

By Chris Baltimore

WASHINGTON (Reuters) - Legendary Texas oil man T. Boone Pickens has gone green with a plan to spend $10 billion to build the world's biggest wind farm. But he's not doing it out of generosity - he expects to turn a buck.

The Southern octogenarian's plans are as big as the Texas prairie, where he lives on a ranch with his horses, and entail fundamentally reworking how Americans use energy.

Next month, Pickens' company, Mesa Power, will begin buying land and ordering 2,700 wind turbines that will eventually generate 4,000 megawatts of electricity - the equivalent of building two commercial scale nuclear power plants - enough power for about 1 million homes.

"These are substantial," said Pickens, speaking to students at Georgetown University on Thursday. "They're big."

Pickens knows a thing or two about big. He heads the BP Capital hedge fund with over $4 billion under management, and earned about $1 billion in 2006 making big bets on commodity and equity markets.

Though a long-time oil man, Pickens said he has embraced the call for cleaner energy sources that don't emit heat-trapping greenhouse gases.

"I'm an environmentalist - I can pass the saliva test," he said.

But Pickens is not out to save the planet. He intends to make money.
