New study casts doubt on ethanol's climate benefits

A new study is casting doubt on the climate benefits of using ethanol as a fuel, finding that it may actually contribute more to global warming than gasoline. Researchers found that emissions from changes in land use to account for the growing demand for corn make corn-based ethanol no cleaner than gasoline. In fact, they determined that these changes likely make ethanol’s emissions at least 24 percent higher than those for gasoline, according to their study, which was published in the Proceedings of the National Academy of Sciences. A 2005 law established what’s known as the “Renewable Fuel Standard” requiring a certain quantity of biofuels, a category that includes ethanol,

Many previous studies showed the same thing, adding that ethanol production wastes a tremendous amount of water, results in unnecessary fertilizer runoff into our waterways (causing algae blooms and other problems), increases particulate matter in the air (leading to increasing cases of asthma they're seeing, but pretending not to know why), harms automobile fuel systems, makes engines run hotter, reduces fuel economy, is terrible for small engines; no benefit at all to anyone but the ethanol producers. But thanks to George W. Bush, the compassionate conservative, Archer Daniels Midland and others make a fortune producing a product we're forced to buy, but is bad for us. (See also rona vaccines.)

Also it is well established that diluting our gasoline with ethanol increases the fuel consumption of gasoline engines.

Plus a lot of mechanic shops refuse to work on cars that use ethanol. They say it melts engine parts. No idea if this is true but it does destroy cars.

The ONLY benefit to ethanol is to the upper midwest farmer's wallets. It is bad for cars, horrible for small engines, reduces fuel economy and range, and causes corrosion in fuel tanks. Nasty stuff, and should be STOPPED. But, the midwest farmers love the extra money, and pay handsomely to politicians who mandate them making more money on their corn, and the huge ethanol plants also make a bunch of money.....and also pay their bribes to the politicians, too. It is now entirely a self sustaining political money making operation, bleeding the tax payers and fuel purchasers for the benefit of farmers, ethanol plant operators and politicians.

If all the grain alcohol they produced were MANDATED to be consumed as MaiTais, then everyone would be passed out drunk all the time and very few miles would be driven, thus saving a lot of fuel. Problem solved. just MANDATE the MaiTais. Thank me very much.

Obviously: you burn one gallon of petroleum (producing CO2 and pollutants) to make one gallon of ethanol. Then you burn the gallon of ethanol (producing CO2 and pollutants) to save the environment; by creating twice as much pollution. Makes as much sense as everything else liberals try to sell us.

Ethanol only harms engines that are not designed to use it. In 60s and 70s muscle cars it eats fuel filters and other engine system parts. It looks like the electric car people are now going after flex-fuel vehicles in order to put an even worse technology at more of an advantage. What will be the next victim, steam engines? Electric cars will not be in our future as the major mode of propulsion, get over it Greenies.

We have all these greenies running around with no true education - but ethanol is wonderful - it is more expensive than gas; cause more corrosion than gas, pollutes more; and harms our climate. Sounds like the same elites who pushed the jab and we may find out too late that it did more harm than good.

History is important here. Two things happened in the 1970s, leading to ethanol mandates. First was the Arab oil embargo. We worried about having enough gasoline. Coincidental to that was moving the Iowa caucuses ahead of the NH primary. That made Iowa an important player in selecting party nominees for president, and those politicians knuckled under to Iowa farmers. Then Jimmy Carter was elected president, and the ethanol requirement was locked in. The only presidential candidate who came out against ethanol, that I can remember, was John McCain in 2008. But when he went to Iowa to campaign, he folded like a cheap suitcase on the issue.

The sister of late fraudster Bernie Madoff and her husband were found dead in Florida in an apparent murder-suicide, authorities said Sunday. Sondra Wiener, 87, and her spouse, Marvin, 90 — whose lives were among those destroyed by Madoff’s $65 billion Ponzi scheme — were discovered dead from gunshot wounds in their home Thursday afternoon in Boynton Beach, the Palm Beach County Sheriff’s Office said. Deputies received a call at 12:55 p.m. about the couple being unresponsive in their residence, authorities said. “Upon arrival, deputies located an elderly female and male deceased from a gunshot wound,” the sheriff’s office said.

"Freedom," warned the Canadian Broadcasting Corporation, which is funded by the Trudeau government, is a word that has "become common among far-right groups." To prove its point, the CBC quoted Elisabeth Anker, a George Washington University prof, who claimed that freedom is a "slippery concept" and that those on the right want "violent" freedoms that reject being "bound by norms of equality" or "norms to remedy inequality." On, in other words, freedom from state coercion to create the ideal society of the state. Anker wrote a book titled Ugly Freedoms which argues that "individual liberty has always been entangled with white supremacy, settler colonialism, climate destruction, economic exploitation, and patriarchy.”

It may seem hard to believe that America’s neighbor to the north is now a full-fledged, up-and-running police state. Heavily-armed police are arresting and, in some cases, roughing up, severely beating, and trampling with horses members of the truckers’ Freedom Convoy in Ottawa as well as bystanders. The country has gone off the rails. Justin Trudeau’s ineffable Justice Minister David Lametti is on record threatening those who hold the wrong political views that they are liable to have their bank accounts seized. “If you are a member of a pro-Trump movement who is donating hundreds of thousands of dollars, and millions of dollars to this kind of thing,” he said,

From the 18th of this month through the 25th, national leaders are meeting in Munich in an apparent effort to deescalate the situation in Ukraine. The administration has pulled together its putative allies to forestall what it claims is an imminent threat by Russia to invade Ukraine. In fact, it discouraged (apparently unsuccessfully) Ukrainian president Volodymyr Zelensky from attending on the ground that war could start any minute and his absence from Ukraine would be taken as flight. Heading the U.S. delegation is Vice-President Kamala Harris, which hardly comforts me. She threatens severe economic sanctions against Russia if they invade. (But this is from the

The Nazis have always been Hollywood’s go-to villains, the bad guys every American who isn’t an antisemite or eugenicist can agree are the epitome of evil. They also serve as a convenient substitute when Hollywood doesn’t want to address America’s real-world enemies; in 2001, for example, when filmmakers were adapting Tom Clancy’s thriller The Sum of All Fears for the big screen, they changed the antagonists from Arab terrorists to European neo-Nazis. But Hollywood’s neo-Nazis of today are – you guessed it – American patriots. Case in point: In the Shadow of the Moon, a late 2019 addition to Netflix’s repertoire which is

Experts are warning that an increase in buried bodies as a result of the COVID-19 pandemic could be having an impact in the environment. In the U.S. alone, the number of people who have died with COVID-19 exceeded 900,000 this month and the number is increasing all the time. Around the world, the death toll is over 5.8 million according to the World Health Organization (WHO), though some estimates of excess mortality—a measure comparing all deaths recorded with those expected to occur—have put that figure close to 20 million. What this means is that burial facilities have faced unprecedented pressure as they attempt to allocate space and resources to store the bodies
