There are significant economic, national security, and environmental costs of the fuel currently used in our transportation system. For example:
Significant advances have been made recently to improve the overall efficiency of the sector, particularly with regards to fuel economy. However, further fuel savings is needed. The traveling public is increasingly investing in alternative fuels, plug-in hybrid and other electric vehicle (EV) technologies. The increased use of these fuels and vehicle technologies promises to yield multiple benefits, including reducing our reliance on foreign sources of oil, lower localized and regional on-road emissions, and reduced energy consumption for the transportation sector. States and localities in the U.S. are beginning to build the necessary infrastructure to support the use of these fuels and vehicle technologies.
