AFBF Economist: E15 Expansion Could Strengthen Corn Demand and U.S. Energy Security

A permanent national E15 standard would boost corn demand, lower fuel costs, and provide a stable path for U.S. energy security.

NASHVILLE, Tenn. (RFD-TV) — Ethanol’s role as a major market for corn and a key pillar of U.S. energy security is back in focus as policymakers debate nationwide, year-round E15 sales, according to analysis by Faith Parum, Ph.D., economist with the American Farm Bureau Federation (AFBF). With gasoline demand projected to decline over the next decade, expanding E15 access is emerging as one of the most important levers for protecting long-term ethanol demand — and the billions of bushels of corn tied to it.

Ethanol currently consumes about 5.6 billion bushels of corn annually, but blend rates have stalled near E10, and outdated summer volatility rules restrict E15 sales in many states. Even with EPA’s temporary summer waivers, the lack of a permanent policy creates uncertainty for retailers and slows investment in pumps, tanks, and signage needed to grow adoption.

For corn farmers, the stakes are large. Without higher blends, domestic ethanol use could fall by 400 million bushels over the next decade. By contrast, moving entirely to year-round E15 could require up to 2.4 billion additional bushels of corn each year—a transformational shift for rural economies and biofuel markets.

Regionally, more than 3,000 U.S. stations already offer E15, and major automakers approve it for modern vehicles. Consumers also benefit: E15 often costs 10–30 cents less per gallon and cuts tailpipe emissions by roughly 46%, strengthening both household budgets and environmental performance.

Farm-Level Takeaway: A permanent national E15 standard would boost corn demand, lower fuel costs, and provide a stable path for U.S. energy security.
