Oil tycoon T. Boone Pickens' TV commercials blasted the airwaves in 2008 with his big idea to get America off foreign oil imports: natural gas and wind energy. Two years later, let’s just make that natural gas. Since the billionaire’s plans for the world’s largest wind farm fell apart in the Texas Panhandle, Pickens has edited his much-hyped “Pickens Plan” to focus primarily on his other big business interest: natural gas. Touting 1.7 million Pickens Plan supporters, he’s now pushing Congress to pass legislation that would offer incentives to convert 18-wheelers and fleet vehicles to run on compressed natural gas, or CNG, rather than diesel. He said if just 8 million of those trucks switch to the domestic-produced fuel, it could cut in half the amount of foreign oil imported by the United States. “I’m all American,” Pickens said on Friday. “Any energy in America beats importing.” The businessman said he is now looking to Canada as a place to build his 500-megawatt wind farm, because he couldn’t get a deal done in Texas.
