In short, yes. One example is the Clean Cities Program: Since Clean Cities' inception more than a decade ago, the use of alternative fuels and vehicles have significantly helped reduce U.S. petroleum consumption. Clean Cities stakeholders have added more than 157,000 alternative fuel vehicles (AFVs) to their fleets, which have displaced approximately 133 million gallons of petroleum. Clean Cities has an impressive track record but strives for continued growth. Program strategies include: -Building more alternative fueling infrastructure. -Targeting niche markets that are well suited for alternative fuels. T-raining coalitions on the transition to hydrogen. -Supporting efforts to enhance the (Alternative Fuel Vehicle) AFV resale market. -To develop new AFV initiatives, Clean Cities plans to collaborate with the U.S. Department of Transportation, Federal Aviation Administration, Federal Highway Administration, and the U.S. Environmental Protection Agency, as well as the U.S. Department of Energy's FreedomCAR and Vehicle Technologies and Hydrogen, Fuel Cells and Infrastructure Technologies programs.
