What does it cost to displace 38 million gallons of petroleum per year? According to the U.S. Department of Energy (DOE), almost $300 million. That's the amount that DOE head Steven Chu announced last week would go from the American Recovery and Reinvestment Act into buying about 9,000 "alternative fuel and energy efficient" vehicles and 542 new refueling locations. The gasoline alternatives being funded by the money include the whole swath of options: including "natural and renewable gas, propane, ethanol, biodiesel, electricity, and hybrid technologies." While not prominently mentioned in the press release, a single hydrogen refueling station in New Haven, Connecticut, in fact, part of the funding (not a surprise). The money is being given out as part of the Clean Cities initiative, a partnership between the government and industry groups with the goal of reducing petroleum use in the transportation sector.
