Billionaire Texas oilman T. Boone Pickens says Bismarck Mayor John Warford is the first mayor in North Dakota to endorse his plan for easing the U.S. dependence on foreign oil.

The so-called "Pickens Plan" aims to cut the country's dependence on foreign oil by putting up wind turbines to replace power produced from natural gas. That would leave more natural gas to power vehicles that now use gasoline and diesel.

Pickens says about 160 mayors in the U.S. have endorsed his plan.
