A study found that the U.S. Renewable Fuel Standard has failed to meet greenhouse gas emission targets but increased corn prices by 30%. The Renewable Fuels Association called the report "a completely fictional and erroneous account of the environmental impacts of the Renewable Fuel Standard."
The carbon intensity of corn ethanol supported by the U.S.'s Renewable Fuel Standard (RFS) is likely at least 24% higher than gasoline, according to a peer-reviewed study from University of Wisconsin researchers.
Researchers determined that the production of corn-based ethanol under the RFS policy "has failed to meet the policy’s own greenhouse gas emissions targets and negatively affected water quality, the area of land used for conservation, and other ecosystem processes." The RFS also pushed prices for corn up by 30% and other crops by 20%, they said.
The study aims to support policymakers as they determine the future of the RFS, which is among the world's largest biofuel programs. The policy was first established in 2008 and is now under review by the Biden administration.
The study, Environmental outcomes of the US Renewable Fuel Standard, will be published in the March issue of Proceedings of the National Academy of Sciences of the United States of America. The work was supported by the U.S. Deptartment of Energy and the National Wildlife Federation, among others. The Bloomberg news service noted that the National Wildlife Federation is a vocal critic of the RFS.
'Precarious' conclusions, shouts trade group
The Renewable Fuels Association, which aims to expand demand for American-made biofuels, said the RFS is the "single most successful clean fuels policy in the U.S." The group said ethanol has saved Americans money, reduced the country's dependence on foreign fuels, and supported job growth.
The Renewable Fuels Association accused the researchers of "precariously" connecting a series of "worst-case scenarios." The trade group's president and CEO, Geoff Cooper, said that the RFA previously met with the study's author and offered to collaborate on research but never heard back.
RFA released a line-by-line rebuttal of the University of Wisconsin study. The group references a study released in 2021 by authors linked to Harvard University and the Massachusetts Institute of Technology that found well-to-wheel greenhouse gas emissions of corn ethanol to be 40% lower than gasoline produced from crude oil.
The authors of Carbon intensity of corn ethanol in the United States attributed declining carbon intensity to improved farming practices, more efficient use of natural gas, and an increasing share of electric generation by ethanol refineries.

Forcing Our Teachers to Toe the Line on Communism
The substance of the meme here is correct; Florida public schools require comprehensive K-12 instruction on the history and dangers of communism, following a series of legislative moves and curriculum standards. The updated “History of Communism” curriculum is rolling out for the 2026–2027 school year, mandating that students learn about the “brutal realities” and (the catastrophic) global impact of communist regimes.
When I was a schoolboy in the 1960s and early 1970s, we came to learn that all efforts to establish a viable communist nation had failed, but our teachers were not shackled as to what they could teach and how they could teach it. As a result, we came to a variety of helpful viewpoints, and these are what I offered my own kids as they were growing up, e.g.,
- “Men are not angels,” as my sixth-grade social studies teacher explained. Those who do not need to work in order to survive can simply goof off.
- Yet idleness is averse to most people’s psychological needs to be an active and productive person, and member of society.
- Power corrupts, and absolutely power corrupts absolutely. Democracy prevents the accumulation of a pathological amount of power on the part of any one leader. (This was assumed to be true until Donald Trump’s second term.)
- If Lenin (a butcher) hadn’t had Trotsky (a compassionate intellectual) assassinated, the entirety of the USSR would have turned out completely differently.
- If the U.S. hadn’t, through its embargoes, made it impossible for Cuba to offer its people a decent quality of life, their revolution may have succeeded and brought forth a new way of thinking.
- There are examples of smaller scale societies in which the ideals of communism work out very nicely, e.g., the Israeli kibbutz.
- We read and discussed at length a book called “Social Ideals and Ideal Societies” in which these concepts were analyzed fairly and in great depth.
Now, will the typical American schoolchild turn out better if he’s cut off from thinking critically about all this and forced to accept the mantra that “communism = evil?” The typical Florida Republican would say the answer is an obvious yes, but most intelligent people would dispute that.
Producing educated people who can think for themselves is an idea quite opposed to the ongoing control of a population.

Trump Supporters Stupid?
To the author of the meme here, I say: It’s safe to say that most folks in Trump’s MAGA base are stupid, though one needs more than a low IQ to fit into this segment.
In particular, we mustn’t omit mean-spiritedness. People who are kind, compassionate, decent and tolerant of others are grossly unqualified to be rank-and-file Trumpers.

Why Trump Works So Hard to Divide Us
Trump appeals to two groups of constituents: a) a small group of billionaires who lavish him with campaign contributions in exchange for huge financial favors, and b) a large number of poorly educated white people who call themselves Christians–the so-called MAGA base.
Trump has little if any appeal to everybody else: honest, fairly well-educated people of a variety of ethnicities and religious affiliations.
For Trump, staying in power means making sure that there is a minimum of leakage away from the MAGA base. That requires barraging these people with messaging to the effect that the president is the only thing standing in the way of communism/socialism, open borders, the invasion of Muslims, godlessness, teaching our little children about LGBTQs, critical race theory, choking environmental regulation, and whatever else may be on the radical left’s agenda.
Maintain this chasm means not letting up on the propaganda for a single minute. No nuance, no critical thinking, no considering what we’ve learned from history–just constant bombardment.
