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.

Geothermal in Iceland
Iceland is lucky enough to have incredible geothermal resources. And while it’s not alone in that regard, most parts of the world require drilling through some of the toughest rock on the planet.
That’s the reason that solar and wind have come to dominate the landscape of renewables; their costs have plummeted in recent years, making things like geothermal noncompetitive in most regions.

Things Have Changed
To the author of the meme here, I respond:
Yes, all this is true. But we must never forget that we voted for this, not once but twice.
Still, a full 30% of us support the lies, the stupidity, and the criminality, while our enemies are popping to the tops off of champagne bottles. Russia took us down without firing a shot. China is making its way toward world domination, largely because the United States committed suicide.
Fifty years ago, we were a reasonably well-educated and principled people.
Now, we’re a blend of greedy pigs and hateful imbeciles.
We have no one to blame for the implosion of America but ourselves.
It would be incorrect to say that literally no one saw this coming, but it took the overwhelming majority of the world by complete surprise.

America’s Cultural, Moral, and Spiritual Decay
Former Republican strategist Steve Schmidt makes an important point here, one that makes us wonder exactly how long it’s going to take to repair the damage that Trump has inflicted on our country.
Let’s say that the midterm elections shift the balance of power in congress and Trump is removed from power in the first half of 2027. Perhaps this will happen on the basis of his senility, using the 25th Amendment. Or better, he’ll be impeached and convicted for any of dozens of the crimes he’s committed.
As much of the physical damage as possible will be undone, almost overnight. No Trump names on public buildings. Tariffs removed. Science re-instated as the pillar of policy making and public health. No more idiot sycophants in key positions. Iran and the U.S. (somehow) move back into the relationship we had before Trump’s asinine and illegal war.
The vast majority of Americans and virtually everyone else on Earth will breathe a huge sigh of relief.
But even if this happens swiftly, it will most certainly not make the “Trump phenomenon” vanish into the mist. People all around the globe will continue to regard the former envy of the world as a nation of hateful idiots, and it’s likely that this perception, as many have suggested, will take a generation or so to lift.
Canadian PM Mark Carney is predicting that, given the implosion of the U.S., that a new world order is forming with Europe as its center. Maybe “a generation or so” won’t get the job done. Maybe American dominance is gone forever.
And maybe that’s not such a bad thing. Imagine for a moment that billionaires didn’t control every facet of life here, and that our nation morphs into one that resembles the more enlightened places on this planet, where its people are well-educated and feel a distinct level of compassion for one another.
