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

Recently, some have made the claim 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.

This is what “energy density” claims leave out: PRICE. Gasoline may pack a hair 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Unfortunately, these cost savings could vanish from many markets as early as May 1 of this year due to outdated federal restrictions on summer sales of higher ethanol blends.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.”

WASHINGTON, D.C. — Growth Energy, the nation’s largest biofuel trade association, today called on lawmakers to act swiftly on E15 following another disappointing farm income forecast from the U.S. Department of Agriculture (USDA).

“Rural America is hurting,” said Emily Skor, CEO of Growth Energy. “Corn growers were already expecting a net loss of $180 per acre, and this latest USDA report confirms that the broader farm income isn’t faring much better. Our growers don’t want to depend on federal aid for their livelihood — they want strong, stable markets for their crops. That’s exactly what E15 delivers — an immediate source of demand for up to 2.4 billion additional bushels of corn — at no cost to taxpayers. Best of all, it means lower fuel prices for American drivers. Congress simply can’t afford to wait any longer to deliver a permanent fix for E15.”
