From the department of the market speaks:
Legendary Texas oil man T Boone Pickens has gone green with a plan to spend $US10 billion ($10.7 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 2700 wind turbines that will eventually generate 4000 megawatts of electricity. This is the equivalent of building two commercial scale nuclear power plants and enough power for about 1 million homes.
"These are substantial," said Mr Pickens, speaking to students at Georgetown University yesterday. "They're big."
