Iowa Secretary of Agriculture Mike Naig highlighted on Apr. 1 the financial benefits for drivers using E15 fuel, following the release of the Iowa Department of Revenue’s 2025 Retailers Fuel Gallons Annual Report.
The announcement is significant for both consumers and the agricultural sector, as increased use of E15 has led to substantial cost savings at the pump and supports local biofuel producers. According to Naig, “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.” He added that broader access to E15 would benefit more Americans: “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.”
The report found that sales of E15 (Unleaded 88) grew by nearly 60 percent from the previous year with over 410 million gallons sold—a record high—saving Iowans an average of about $61.5 million compared to using standard E10 gasoline. The number of retailers selling E15 also rose sharply; more than half now offer it statewide.
Iowa has made biofuels a priority as part of its strategy to reduce gas prices and support local agriculture by requiring most fuel retailers to sell or market E15 unless exempted by waiver. Since passing this standard in 2022, participating retailers have tripled—from just over 300 then to more than 1,100 today—with additional investments planned through infrastructure upgrades.
The Iowa Department of Agriculture and Land Stewardship supports such initiatives with no-interest loans and grants for conservation practices according to its official website. The department promotes social growth by enhancing rural areas alongside economic development according to its official website. Its mission includes championing farmers while safeguarding natural resources according to its official website.
Iowa leads nationally in pork, corn, eggs, ethanol, and biodiesel production according to its official website, supported by programs that aid agriculture across land and water resources statewide according to its official website. Policy efforts like the Iowa Nutrient Reduction Strategy further address environmental impacts from farming according to its official website.
Through partnerships focused on conservation funding and environmental practices—and under state governance—the department continues bolstering rural economies while maintaining consumer protections according to its official website.
