In 2012, about 14 million barrels of oil per day was transformed into transportation fuels, including gasoline, diesel and jet fuel.
Gov. Mary Fallin has helped lead an effort to encourage automakers to produce natural gas-powered cars and trucks for state fleets. The state earlier this month received its first batch of 242 new compressed natural gas-fueled 2013 Ram 2500 trucks.
The effort is now backed by 21 other states.
Native Oklahoman and oilman T. Boone Pickens has helped lead an effort to encourage the country's trucking fleets to convert to natural gas.
Former Central Intelligence Agency Director James Woolsey this month told participants at the University of Oklahoma Energy Symposium that he would like to see the country follow the examples of Brazil and Israel, where vehicles are designed to run on multiple fuels.
“A driver in Brazil can use either gasoline or ethanol. Hopefully in the U.S., we will be able to drive on gasoline, ethanol or methanol made from natural gas,” Woolsey said. “It's going to be even more embarrassing if we fall behind the Communist Chinese with choice at the pump.”
