Clean Cities and Communities Alternative Fuel Price Report, January 2025

4/21/2025

The Clean Cities and Communities Alternative Fuel Price Report for January 2025 is a quarterly report on the prices of alternative fuels in the U.S. and their relation to gasoline and diesel prices. This issue describes prices that were gathered from Clean Cities and Communities coalition directors and stakeholders between January 1, 2025 and January 15, 2025, 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 2 reports that the nationwide average price (all amounts are per gallon) for regular gasoline has decreased 19 cents from $3.25 to $3.06; diesel decreased 9 cents from $3.64 to $3.55; CNG increased 8 cents from $2.91 to $2.99; ethanol (E85) decreased 17 cents from $2.74 to $2.57; propane decreased 2 cents from $3.35 to $3.33; and biodiesel (B20) decreased 19 cents from $3.53 to $3.34.

According to Table 3, CNG is 7 cents less than gasoline on an energy-equivalent basis and E85 is 28 cents more than gasoline on an energy-equivalent basis.

Model Year 2025 Fuel Economy Guide: EPA Fuel Economy Estimates

12/4/2024

The Fuel Economy Guide is published by the U.S. Department of Energy as an aid to consumers considering the purchase of a new vehicle. The Guide lists estimates of miles per gallon (mpg) for each vehicle available for the new model year. These estimates are provided by the U.S. Environmental Protection Agency in compliance with Federal Law. By using this Guide, consumers can estimate the average yearly fuel cost for any vehicle. The Guide is intended to help consumers compare the fuel economy of similarly sized cars, light duty trucks and special purpose vehicles.
