Secretary Naig Highlights Savings from E15 in Iowa's Annual Retailers' Fuel Gallons Report

Nearly 60 percent increase in E15 sales saved Iowa drivers over $60 million in 2025

DES MOINES, Iowa (Apr. 1, 2026) - Iowa Secretary of Agriculture Mike Naig today highlighted the significant savings Iowa drivers are seeing from choosing E15 at the gas pump following the release of the 2025 Retailers Fuel Gallons Annual Report by the Iowa Department of Revenue.

"In 2025 alone, E15 delivered more than $60 million in savings for Iowa drivers-and $126.5 million over the past three years. That's real money back in the pockets of families and small businesses at a time when affordability matters most," said Secretary Naig. "Not only is E15 a win for consumers, but it also provides stronger markets for Iowa farmers and biofuel producers, creates jobs in rural communities, and enhances domestic energy independence. We want all Americans to enjoy these same savings and benefits, and that is why Congress must take immediate action to approve year-round, nationwide access to E15."

Key E15 (Unleaded 88) Highlights from the 2025 Report:

• Nearly 60 percent increase in E15 sales, generating more than $60 million in savings for Iowa drivers in 2025 alone by choosing E15 over E10
  
  • 410,096,572 gallons of E15 sold, a 59.7% increase from 2024 (up 153,359,421 gallons year-over-year)
  • At an average savings of 15 cents per gallon compared to E10, Iowa drivers saved approximately $61.5 million in 2025 by choosing E15
• Momentum for E15 use and availability in Iowa continues to grow and accelerate
  
  • 1,062 retailers reported E15 sales in 2025, representing more than half of the fuel retailers in the state of Iowa, and 69% of total gasoline gallons sold statewide
• Record E15 sales in Iowa in 2025
  
  • E15 accounted for 27.2% of all gasoline sales in Iowa, up from 17.2% in 2024

Investing in Biofuels Infrastructure

The state of Iowa has prioritized biofuels as part of a broader strategy to reduce gas prices, increase consumer choice and develop markets for Iowa-grown products. Iowa is the first state in the nation to require most fuel retailers to sell and market E15, unless they qualify for a waiver or exemption.

When the E15 Access Standard was passed by the Iowa Legislature in 2022, only 329 Iowa fuel retailers reported sales of E15, and now that number has more than tripled. To date, more than 1,100 fuel retailers in Iowa are selling E15, representing more than half of the 2,051 commercial fuel retailers licensed in the state. More than 150 additional fuel retailers are investing in infrastructure upgrades and plan to offer E15 by the end of 2026, reinforcing Iowa's commitment to making higher blends of biofuels more readily available to drivers.

For 20 years, the State of Iowa has helped fuel retailers transition to selling higher blends of ethanol and biodiesel through the Renewable Fuels Infrastructure Program (RFIP). Funded by the Iowa Legislature and administered by the Iowa Department of Agriculture and Land Stewardship (IDALS), the cost-share program has invested more than $72 million in biofuels infrastructure projects since 2006. Those public investments have been matched by more than $280 million in private investment. The result is a growing network of fueling locations that give consumers more choices and reinforce Iowa's position as a national agricultural and biofuels leader.
