The Ethanol Fallacy: A 2025 Update

The Ethanol Fallacy
January 22, 2008

Public domain

The February 2008 issue of Popular Mechanics features a challenging story by editor James B. Meigs called The Ethanol Fallacy. Unless you’ve been sleeping in a cave for two decades, you’ve undoubtedly been aware of the ongoing debates regarding the best way to reduce our dependence on foreign oil. A wide range of technologies has been evaluated from solar and wind energy to hydrogen power and fuel cells. Since transportation eats up the lion’s share of our energy use, much of the debate centers on how to power our cars and trucks.

Unfortunately, writes Meigs, the best solutions may not be getting the attention they deserve. Washington politicians have bought the “ethanol solution” hook, line and sinker.

Politicians have been falling all over themselves to prove their commitment to energy independence. The bill they have been crafting and carving has as its moniker the title “Energy Independence and Security Act of 2007.” No longer just an energy bill, it is a security matter, giving it a special reverence. According to Meigs, the 2008 presidential candidates “have outdone each other with vows to flood the nation with ever-increasing rivers of ethanol for at least a generation.”

It’s what our politicians love to do, of course. Take action fast. Look like a leader. Problem is, “shoot first, ask questions later” is a silly way to approach these kinds of issues.

The average person who votes is not really that knowledgeable about these matters, which gives the ethanol lobbyists a leg up. The truth is, it takes energy to make energy. The article points out that growing corn requires nitrogen fertilizer, a product of natural gas, and chemical herbicides, made mostly from oil. The heavy machinery that harvests these 93 million acres of corn all require diesel fuel and lubricants, as do the trucks that transport all this corn. According to one Cornell researcher, it takes more than a gallon of oil to make a gallon of ethanol. Now what’s that all about? How does this reduce our dependence on foreign oil.

There’s something corny about this ethanol business. As I have always suspected, and which the author here is not afraid to point out, the big winners are companies like Archer Daniels Midland whose lobbyists labor night and day in those corridors of power inside the beltway. And for who’s benefit? Not yours or mine.

So what can we do about it? Not sure, really. Any suggestions?

It's been 17 years since I penned the above piece and, if anything, the ethanol saga has only grown more entrenched—and more problematic. Back in 2008, the Energy Independence and Security Act was the shiny new toy, mandating a ramp-up to 36 billion gallons of renewable fuels by 2022, with corn ethanol as the star. Politicians from both parties hailed it as a win for energy security, rural economies, and the environment. But as the Popular Mechanics piece I referenced warned, it was a rushed fix, propped up by lobbying muscle from agribusiness giants like Archer Daniels Midland (ADM). 

Fast-forward to today, and the "rivers of ethanol" promised by those 2008 presidential candidates have become a flood—one that's drowning common sense in subsidies, environmental strain, and higher grocery bills.

Let's start with the numbers on corn, which is the heart of the original critique. In 2007, about 14% of the U.S. corn crop—roughly 2.05 billion bushels out of 14.5 billion total—went to ethanol production. Fast-forward to the 2023-24 crop year, and that figure has ballooned to a staggering 5.45 billion bushels, or nearly 45% of the total harvest. That's enough corn to fill over 200,000 Olympic-sized swimming pools, diverted from food, feed, and exports to chase the biofuel dream. 

Some reports even peg it higher when including co-products like distillers grains used in animal feed, pushing the effective share past 50% for biofuel and alcohol combined. Meanwhile, total U.S. corn production hit a record 15.2 billion bushels in 2023, but the ethanol slice keeps growing—projected to hold steady at 5.45 billion bushels for 2024-25. Farmers love the demand (and the prices it props up), but at what cost to the rest of us?

What's weird to me is how Paul Ehrlich in his bestseller The Popular Bomb (1968) stated the global food supply would not be able to keep up with much more population growth. The world population was 3.5 billion then. Now we're over 8 billion people and instead of using farming to provide food we're using it for fuel. What's with that?

The energy math hasn't improved either. That Cornell researcher I quoted in 2008 nailed it: it still takes roughly a gallon of fossil fuels to produce a gallon of corn ethanol. Recent analyses peg the energy return on investment (EROI) at just 1.04:1 for corn-based ethanol—meaning you get back barely more energy than you put in, and that's being generous. 

For context, gasoline clocks in at 8:1 or better; even tar sands beat ethanol at 4:1. No wonder critics call ethanol a "net energy sink" for society—it's like running on a treadmill to power your house. And the environmental toll? Corn ethanol's full lifecycle emissions (including fertilizer runoff, soil erosion, and methane from processing) often make it as dirty as—or dirtier than—regular gasoline, especially when indirect land-use changes like deforestation abroad are factored in. It's led to toxic algae blooms in the Gulf of Mexico, higher water bills for Midwest communities, and a "food vs. fuel" dilemma that's jacked up global prices for everything from tortillas to turkey.

So why is nobody talking about this!!!!

Policy-wise, the machine keeps humming. The Renewable Fuel Standard (RFS), that 2007 mandate, is still law, with EPA-set volumes ticking up: 21.87 billion gallons of total renewable fuel in 2024 and 22.68 billion in 2025, much of it corn ethanol. Direct blender's tax credits may have expired in 2011, but they've been replaced by a subsidy buffet. The new Clean Fuel Production Credit (Section 45Z), kicking in fully in 2025, dangles up to $1 per gallon for low-emission biofuels—potentially costing taxpayers $8.5 billion in FY2031 alone. Add in $3.2 billion in direct farm subsidies for corn in 2024 (30% of all commodity crop aid), and it's clear the lobbyists are still earning their keep. ADM and peers aren't complaining: the industry pumped out a record 16 billion gallons of ethanol in 2024, supporting 370,000 jobs and $30 billion in inputs—but mostly in rural pockets, while urban families foot the bill through higher feed costs and pump prices.

So, has anything changed for the better? Some might say there are a few positive glimmers in the data. Exports hit 1.91 billion gallons in 2024, easing some domestic pressure, and there's buzz around "second-generation" ethanol from waste or algae, which could sidestep the food fight, though it's years from scaling, and I'll believe i when I see it. (I suspect I will be dead before then.) Electric vehicles are finally denting the transportation pie—EVs made up 7.6% of new car sales in 2023, up from zilch in 2008—and wind/solar now outpace ethanol in renewable energy growth. But corn ethanol clings on, a relic of that "shoot first" era.

What can we do? Demand better. Will Congress be open to reforming the RFS toward truly sustainable biofuels. Better yet, vote with your wallet—seek out E0 (ethanol-free) gas if your state allows. The fallacy isn't just corny anymore; it's costly. Time to harvest smarter solutions before we ethanol-ize our way into a bigger mess. 

What do you think—still buying the hype? 

Contrarian Observations, January 3, 2025

"The Rock & Roll Hall of Fame induction ceremony, which took place last October and was rebroadcast on ABC on New Year’s Day, is a reminder of why rock and roll doesn’t need a hall of fame."

I have been recently introduced to a new source of climate-related common sense, a substack called Energy Talking Points by Alex Epstein. Here is an insight.

"It’s an irrefutable but little-known fact that as the world has warmed 1° C, humans have become safer than ever from climate danger. The rate of climate-related disaster deaths—from storms, floods, temperature extremes, wildfires, and drought—has fallen 98% in the last century." 

Machines powered by abundant energy have allowed us to:

• master drought danger via irrigation and crop transport,
• master temperature danger via heating and A/C,
• master storm danger via building resilient infrastructure plus storm warning and evacuation systems

30 Miscellaneous Dylan Clippings Discovered While Doing Research for Bob Dylan in Minnesota

I suspect that most journalists love doing research. I know that I do. That's half the fun of being a writer. Especially when you discover surprises like a giant shark's tooth on a Maryland beach or an unusually spectacular agate on the North Shore.

While trying to get some facts straight for the book Bob Dylan In Minnesota (the fourth book in K.G. Miles' Troubadour Series) I enjoyed a leisurely afternoon scanning through clippings from our local newspapers and tabloids. It was especially funny to come across a few things I myself had written.

As every Dylanophile knows, there are more than a few contradictory facts that you can find in the various books about Bob. As the saying goes, it is what it is. 

Here's a batch of clippings, some of which you may or may not have seen before. A few are not local, as you will notice. I'll try to share more soon. There are a lot of them and every picture tells a story.

Hilarious "oops"... This is the Duluth Hillside home. Not Hibbing.

THIS is the Hibbing house... a few decades ago.

Have a fun weekend. It's Grandma's Marathon in Duluth. 

And Father's Day on Sunday. Happy Father's Day to all you dads.

If you forgot to get your pa a Father's Day gift,

On Behalf of Mama Earth

Earth Day, April 22, came and went again this week. According to one source twenty million people celebrated the first Earth Day in 1970. President Nixon gave us the Environmental Protection Agency that year and Congress amended the Clean Air Act to set national air quality, auto emissions, and anti-pollution standards.

I am still curious why the so-called "founders" of Earth Day 1970 actually switched it from the Vernal Equinox, which has been historically honored as Earth Day for more than three thousand years, at least in the Northern Hemisphere. When Secretary-General U Thant in 1971 signed a U.N. Earth Day Proclamation on March 21, 1971, he must not have been paying attention to those press releases the year before that announced it had been moved to April 22.

For me personally, I don’t really care what date is officially Earth Day. What's more important is a lifestyle commitment. If you still pour out your used motor oil in the back yard, I don’t care how many Earth Day ceremonies you’ve been to, you obviously don’t “get it.”

There’s a school of philosophy that says in essence “what is is what is.” It is a somewhat fatalistic approach to life and reality. It implies powerlessness, as if to say that we have no power to change things, so why bother, as if we are victims of Fate.

I would suggest that we have far more power than we realize to make a difference. It begins with this commitment: I will do what I can in the realms where I am able.

I’m not trying to make this into a moral issue. But in point of fact, if human beings don't take care of the earth, you won’t see sheep, chimps or elephants stepping up to take the lead. The responsibility is ours, both collectively and individually.

SHAMELESS PLUG FOR MY COMPANY
What this means is, we need to learn more about what we can do. We’ve all seen the lists. Turn lights off in unoccupied rooms, use energy-efficient appliances, etc. One item not usually listed is to use a premium synthetic oil and extend intervals between oil changes. Fact: AMSOIL synthetic motor oils last longer than conventional petroleum motor oils. The net benefits to our environment on this alone include less packaging waste and less waste oil to dispose of.

But the benefits of AMSOIL synthetics go further than this. The best synthetics clean the engine so it runs in a more optimal manner. The net result is improved fuel economy. That is, cars can use less fuel to go the same distance. If every car and truck were switched to premium synthetic motor oils, the savings alone would enable a vehicle could go to the sun and back (186 million miles round trip) so many times that it would blow your mind.

I am not makng this up.
