E15 Saves Consumers Money
Setting the record straight on ethanol’s energy density

Recently, there have been claims that ethanol is more expensive than gasoline because it has a lower energy density. The truth is that ethanol blends like E10 and E15 have almost the same heat energy (measured in BTUs) as non-ethanol gasoline, but they are offered at a much lower retail cost. On a cost per BTU basis, ethanol-blended fuels are less expensive than non-ethanol fuels.

Price of Fuel per million BTUs

This is what “energy density” claims leave out: PRICE. Gasoline may pack slightly more energy per gallon, but ethanol blends cost so much less that drivers get more energy for every dollar spent — savings that show up directly at the pump.

With high inflation and volatile gas prices, American drivers are increasingly relying on the fuel savings offered by E15 (UNL88), a fuel containing 15 percent American ethanol. Compared to standard 10 percent blends (E10), E15 saved American drivers an average savings of up to 30¢ per gallon — all while increasing U.S. energy security and supporting economic growth across rural America.

Unfortunately, these cost savings could vanish from many markets as early as May 1 of this year due to outdated federal restrictions on summer sales of higher ethanol blends.

For the last seven years, American drivers have uninterrupted access to E15 year-round based on actions taken by the Environmental Protection Agency (EPA). In January 2025, President Trump issued an executive order (EO) declaring a national emergency over energy, which, in Section 2(b) of the EO, orders EPA to “consider issuing emergency fuel waivers to allow the year-round sale of E15 gasoline to meet any projected temporary shortfalls in the supply of gasoline across the Nation.”
