Expansion of E15: A Gift to the Ethanol Lobby and a Consumer Betrayal

It is time to get out of ethanol and other renewable fuels that deliver no real benefit to the environment or to American consumers. The latest push for year-round sales of E15 — gasoline blended with 15% ethanol — is not deregulation or consumer choice. It is a Trojan horse for expanding the Renewable Fuel Standard (RFS), one of the most costly and destructive federal mandates in U.S. history. As detailed in a recent opinion piece by Reps. Scott Perry (R-Pa.) and Chip Roy (R-Texas) in The Hill, E15 entrenches a hidden gas tax, drives up food and fuel prices, slashes vehicle efficiency, threatens refining jobs, and undermines American energy dominance.

Republicans who champion free markets and affordable energy should reject it outright. The ethanol lobby’s real goal is not competition — it is continued government favoritism that props up an industry that cannot stand on its own merits.

Consumers Pay the Price at the Pump and in the Garage

E15 is not the bargain proponents claim. Ethanol contains about 33% less energy per gallon than pure gasoline, so drivers get fewer miles per gallon. The U.S. Department of Energy’s FuelEconomy.gov notes that vehicles typically see a 3–5% drop in MPG on E15 compared with straight gasoline (and about 1.5–2% less than E10). Real-world testing confirms this: a University of California study and Stillwater Associates analysis show E15’s lower energy density forces drivers to buy more fuel for the same distance traveled. At current prices, that “discount” at the pump evaporates quickly.

Worse, E15 damages engines. Consumer Reports and automaker tests have repeatedly shown that ethanol’s corrosive properties attack rubber seals, hoses, gaskets, fuel pumps, injectors, and valves — especially in vehicles made before 2001, motorcycles, boats, and small engines like lawnmowers. Older engines suffer valve and cylinder-head damage that can cost thousands to repair. Even in newer cars, ethanol attracts water, leading to corrosion, stalling, and higher repair bills over time.

The Alliance of Automobile Manufacturers and multiple studies (including a Coordinating Research Council durability test) documented these effects years ago, yet the mandate rolls forward.

Ethanol Is an Energy Loser and an Environmental Wash

Producing corn ethanol often requires as much — or more — energy as it delivers. Peer-reviewed analyses place the energy return on investment (EROI) for U.S. corn ethanol at roughly 1.2:1 to 1.5:1 at best — meaning you invest nearly as much energy as you get back. Some studies, including those by David Pimentel and others, have shown negative net energy when full lifecycle costs (fertilizer, farming, distillation, transport) are counted. By comparison, conventional gasoline delivers far higher returns. Ethanol does not enhance energy security: one-third of the U.S. corn harvest yields only about 10% of our gasoline supply. Scaling it to replace petroleum would require impossible expansions of cropland.

Environmentally, corn ethanol is no savior. Full lifecycle emissions often match or exceed those of gasoline, with an abatement cost of roughly $1,464 per metric ton of CO₂ avoided. It increases smog-forming pollutants — the very reason E15 was originally banned in summer months. And it drives land-use changes: forests, wetlands, and grasslands converted to cornfields release stored carbon and destroy habitats.

Billions in Taxpayer Subsidies That Could Grow Food Instead

The RFS functions as a 30-cent-per-gallon hidden tax on gasoline and diesel. Over the past decade, it has cost Americans roughly $164 billion in higher fuel prices. EPA analysis projects another $6.7 billion in societal costs from further expansion. The final mandated gallons of ethanol effectively cost society up to $770 per gallon to force into the market.

These subsidies distort agriculture. Roughly 38–40% of the U.S. corn crop (about 5.6 billion bushels annually) goes to fuel instead of food or feed. This diverts nearly 30 million acres — an area the size of New York State — and adds $4.9–$6.8 billion yearly to U.S. food expenditures. Studies link ethanol demand to 2–4% higher corn prices per billion gallons mandated, with ripple effects on beef, pork, poultry, eggs, and dairy. The “food vs. fuel” debate is not myth: global food price spikes in 2007–2008, 2010–2011, and 2012–2013 were partly driven by biofuel mandates, according to analyses from the IMF, IFPRI, and others.

Taxpayers foot the bill through the RFS, tax credits (including the 45Z Clean Fuel Production Credit), and infrastructure subsidies — billions annually that could instead support actual food production or deficit reduction.

A Responsible Phase-Out Program: Protect Farmers, Free the Market

Farmers deserve stability, not a sudden cliff. A smart, ramped phase-out of corn-ethanol subsidies and the conventional biofuel mandate can protect rural America while delivering relief to consumers and the environment. Here is what a practical program could look like, building on ideas outlined in recent Energy News Beat analysis:Years 1–5: Linear Ramp-Down — Reduce the conventional (corn) biofuel RFS mandate from the current 15 billion gallons to zero over five years. Maintain or modestly expand only truly advanced and cellulosic targets that deliver genuine net benefits.

Targeted Transition Payments — Redirect a portion of existing subsidy dollars into time-limited, direct payments tied to historical ethanol-corn acres.

These would help growers shift to food-grade corn, soybeans, wheat, or other export-oriented and higher-value crops. Total cost would be far lower than today’s open-ended tax credits and RIN-market distortions.

Co-Product Incentives — Remove blending mandates so ethanol producers and farmers can compete freely. Distiller’s grains and other co-products remain valuable livestock feed, cushioning the transition.
Sunset All Related Subsidies — Phase out the 45Z credit and any remaining blender credits on the same timeline.
Monitoring & Support — USDA-led technical assistance for crop diversification, soil health programs, and export market development to ensure no net loss in farm income.

This is not “anti-farmer.” It is pro-farmer and pro-consumer. It ends the distortion that forces corn into tanks instead of tables and lets markets reward genuine innovation instead of mandates.

Time for Fuel Freedom, Not Corporate Welfare

Year-round E15 without RFS reform is not progress — it is a gift to the ethanol lobby and a betrayal of every American who fills a tank or buys groceries. Ethanol’s promises have failed: it does not save energy, clean the air, or lower costs. It enriches special interests while leaving consumers with worse mileage, higher repair bills, and pricier food.

Congress must cap and phase down the RFS aggressively — 20 percentage points annually over five years until the mandate ends — and allow every fuel to compete on a level playing field without subsidies or mandates. Only then will we achieve real energy dominance, lower prices, and honest environmental progress.

The choice is clear: government-mandated fuel for the ethanol lobby, or fuel freedom for Americans.
