Clean Cities and Communities Alternative Fuel Price Report, July 2025

10/7/2025

The Clean Cities and Communities Alternative Fuel Price Report for July 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 July 1, 2025 and July 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 4 cents from $3.23 to $3.19; diesel increased 11 cents from $3.65 to $3.75; CNG decreased 7 cents from $3.08 to $3.01; ethanol (E85) decreased 10 cents from $2.82 to $2.72; propane decreased 13 cents from $3.37 to $3.24; and biodiesel (B20) increased 30 cents from $3.47 to $3.77.

According to Table 3, CNG is 18 cents less than gasoline on an energy-equivalent basis and E85 is 35 cents more than gasoline on an energy-equivalent basis.
