Clean Cities Alternative Fuel Price Report, March 2007

3/1/2007

The March 2007 Clean Cities Alternative Fuel Price Report is a quarterly report keeping you up to date on the prices of alternative fuels in the U.S. and their relation to gasoline and diesel prices. This issue discusses prices that were gathered from Clean Cities coordinators and stakeholders between February 21, 2007 and March 2, 2007, and then averaged in order to determine regional price trends by fuel and variability in fuel price within regions and among regions. The prices collected for this report represent retail, at-the-pump sales prices for each fuel, including Federal and state motor fuel taxes.

Table 1 illustrates that alternative fuel prices relative to conventional fuels vary, with some (propane and biodiesel) higher and some (E85 and CNG) lower. CNG is about 36 cents less than gasoline on an energy-equivalent basis, while E85 is about 20 cents less per gallon than gasoline.
