The number of E85 stations in the US has now exceeded 1,800, according to The National Ethanol Vehicle Coalition (NEVC). There are currently 1,802 private and public refueling stations across the US—a 28% growth since October 2007.

Currently, the states with the highest number of E85 sites are: Minnesota with 357, Illinois with 188 and Missouri with 112. Unfortunately, seven states do not offer E85 including: Maine, New Hampshire, Vermont, Rhode Island, New Jersey, Alaska and Hawaii.
The public can fuel at 1,693 of the 1,802 stations nationwide. A listing of E85 sites can be found at http://www.E85Refueling.com.
Currently, E85 fuel is averaging $2.68/gallon nationwide, compared to the average unleaded price of $3.27—an 18% price spread. E85 has between 23-28% less energy per gallon than gasoline, according to the US Department of Energy.
The ethanol content of E85 is usually lower than 85% for two reasons: 1) fuel ethanol contains 2-5% gasoline as a denaturant and 2) fuel ethanol content is lowered to 70% in the winter in cold climates to facilitate cold starts. When the actual composition of E85 is accounted for, the lower heating value of E85 varies from 82,970 Btu/gal to 89,650 Btu/gal, which is 72% to 77% the heat content of gasoline.
