The Big Oil-Big Biofuel wars rage on. From my perch, ethanol, biodiesel and “advanced biofuels” make about zero energy, economic or environmental sense. They make little political sense either, until you recognize that politics is largely driven by crony-capitalism, campaign contributions and vote hustling.
Even now, once again, as you read this, White House, EPA, Energy, Agriculture and corporate factions are battling it out, trying to get President Trump to sign off on their preferred “compromise” – over how much ethanol must be blended into gasoline, how many small refiners should be exempted, et cetera.
This all got started in the 1970s, when publicly spirited citizens persuaded Congress that “growing our own energy” would safeguard the USA against oil embargoes and price gouging by OPEC and other unfriendly nations, especially as our own petroleum reserves rapidly dwindled into oblivion. Congress then instituted the Renewable Fuels Standard in 2005, when the Iraq War triggered renewed fears of global oil supply disruptions. The RFS requires that almost all gasoline sold in the USA must contain 10% ethanol – which gets a third fewer miles per gallon than gasoline and damages small engines.
But, we were told, these fuels are renewable, sustainable, a way to prevent “dangerous climate change.”
It’s all bunk. In recent years, the horizontal drilling and hydraulic fracturing (fracking) revolution has given America and the world at least a century of new oil and natural gas reserves.America has become the world’s largest oil and gas producer and within five years could be producing far more oil and gas than any other country in the world. Terminals built years ago to import fuel from distant lands are being reconfigured to export abundant US oil, liquefied natural gas and refined products to distant lands.
Average global temperatures – as actually measured by satellites and weather balloons – are now almost a full degree Fahrenheit lower than predicted by climate models (the average of 102 IPCC computer model forecasts) that also foretell the daily litany of climate and weather cataclysms. However, hurricanes are less frequent and intense than a half-century ago, and Harvey was the first Category 3-5 hurricane to make US landfall in a record 12 years. Violent F4-5 tornadoes have also been less frequent over the past 34 years than during the 35 years before that, and not one F4-5 tornado hit the USA in 2018.
Over their full life cycle (from planting, growing and harvesting crops, to converting them to fuel, to transporting them by truck or rail car, to blending and burning them), biofuels emit just as much (plant-fertilizing) carbon dioxide as oil-based gasoline and diesel. Those biofuels also require enormous amounts of land, water, fertilizer, insecticides and energy. None of this is renewable or sustainable.
In fact, corn turned into E85 fuel (85% ethanol/15% gasoline) and grown where rainfall is insufficient requires irrigation – and up to 28 gallons of water from rivers or groundwater supplies per mile traveled!
US ethanol production utilizes 38% of America’s corn and 27% of its sorghum – grown on cropland the size of Iowa: 36 million acres, much of which would otherwise be wildlife habitat. And the fertilizers used to grow those crops, especially the corn, result in nutrient-rich runoff that increases nitrogen levels in the Gulf of Mexico, causing deadly algal blooms. When the algae die and decompose, they create low and no-oxygen zones the size of Delaware – killing marine life that can’t swim away quickly enough.
In short, biofuels have huge downsides and do nothing to address the scary scenarios that have either shriveled amid the winds of history – or were wildly exaggerated or imaginary to begin with.
But once these biofuel programs were launched, they became permanent. They created a biofuel industry that wants to get bigger every year, and supports politicians who want to get reelected year after year. That brings us back to the Executive Branch biofuel battles – and to issues that I myself struggle to comprehend, amid the morass of acronyms and conflicting policies and mandates.
Congress and the Environmental Protection Agency require that refiners blend “conventional biofuel” (mostly ethanol) into gasoline – and also meet various “advanced biofuel” and biomass-based diesel requirements. However, too much ethanol in gasoline damages engines in older cars, generators, garden equipment and boats; that puts a limit on how much ethanol can actually go in the fuel supply (the “blend wall”). As a result, while ethanol blending continues to increase gradually, American motorists have never been able to consume enough ethanol to satisfy applicable Renewable Fuel Standards.
However, biofuel interests want the government to keep mandating even more ethanol – a desire that faces multiple problems. Gasoline demand is decreasing, as people drive less, in more fuel-efficient cars, and in electric and hybrid vehicles (that are heavily subsidized under other laws).
Tariff wars with China and other countries have hurt corn and sorghum farmers, who want to be “compensated” via more biofuel mandates under the Renewable Fuels Standard – even though beef, pork and poultry farmers get hurt by higher grain prices resulting from so much corn devoted to ethanol.
Declining fuel demand and the blend wall mean refiners cannot mix all the mandated 15 billion annual gallons of ethanol into gasoline. They are thus forced to over-comply with the “advanced biofuel” part of the RFS mandate by buying expensive foreign biodiesel and “renewable” diesel. Refiners that do not control the point where biofuel can be blended into gasoline (eg, large distribution terminals or local gas stations) must buy “credits” called Renewable Identification Numbers (RINs) that show (or pretend to show) the required (foreign) biofuels were mixed with the gasoline they make domestically.
This all gets really expensive, really fast, which is why the law allows exemptions to small refiners that face “disproportionate economic hardship” from costs that have gotten so high that courts have ordered the EPA to grant more “small refinery exemptions” (SREs) – waivers from the RFS mandates.
However, biofuel has been blended into the fuel small refiners make anyway. This situation resulted in ample supplies of RFS compliance credits, and RIN prices have dropped from over 90 cents apiece to 12 or 20 cents over the past two years or even lower at times. Of course, this all angered the biofuel lobby, which has attacked the administration for issuing SREs, falsely claiming the exemptions are “destroying demand” for biofuel and “hurting American farmers.”
They levied these attacks on EPA, despite the fact that the Trump administration granted the biofuel industry its biggest request in 20 years: an air quality waiver that allows E15 to be sold year round. So some in the administration have proposed to “reallocate lost biofuel gallons” the biofuel industry says were caused by SREs. But there’s nothing to reallocate, since ethanol is being blended despite the SREs.
The reallocation proposal thus has the practical effect of increasing the biofuel mandate by over 700 million gallons above the 15 billion-gallon statutory ceiling on ethanol. That brings us back to the fact that America is not producing enough advanced biofuels, biodiesel or renewable diesel. That means refiners have to buy more foreign supplies of these fuels, from Argentina, Brazil, Indonesia, et cetera.
Of course, that does nothing to help American farmers. It just turns the Renewable Fuel Standard into a big foreign biofuel mandate. It also means President Trump is caught between trying to placate two of his core constituencies: farmers, primarily in the Midwest, and the oil and refining industry with all its jobs.
This is mind-numbingly complicated. But the bottom line is pretty simple: Every time Congress gets involved in trying to fix complex energy and economic problems – instead of letting free market industries and innovators sort things out – it creates a legislative, regulatory, legal and lobbying mess. Every attempted additional fix makes things worse. And trying to justify all the meddling, by claiming we’re running out of oil or face manmade climate cataclysms, just makes things worse.
We should end this crazy-quilt biofuel program. But anyone who thinks that will happen in Washington, DC or Des Moines, Iowa is smoking that stuff that’s now legal and widespread in Boulder, Colorado. But President Trump and his EPA should at least reduce – and certainly not increase – any biofuel quotas.
