Lies of Ethanol

From Rolling Stone:

The great danger of confronting peak oil and global warming isn't that we will sit on our collective asses and do nothing while civilization collapses, but that we will plunge after "solutions" that will make our problems even worse. Like believing we can replace gasoline with ethanol, the much-hyped biofuel that we make from corn.

Ethanol, of course, is nothing new. American refiners will produce nearly 6 billion gallons of corn ethanol this year, mostly for use as a gasoline additive to make engines burn cleaner. But in June, the Senate all but announced that America's future is going to be powered by biofuels, mandating the production of 36 billion gallons of ethanol by 2022. According to ethanol boosters, this is the beginning of a much larger revolution that could entirely replace our 21-million-barrel-a-day oil addiction. Midwest farmers will get rich, the air will be cleaner, the planet will be cooler, and, best of all, we can tell those greedy sheiks to fuck off. As the king of ethanol hype, Sen. Chuck Grassley of Iowa, put it recently, "Everything about ethanol is good, good, good."

This is not just hype -- it's dangerous, delusional bullshit. Ethanol doesn't burn cleaner than gasoline, nor is it cheaper. Our current ethanol production represents only 3.5 percent of our gasoline consumption -- yet it consumes twenty percent of the entire U.S. corn crop, causing the price of corn to double in the last two years and raising the threat of hunger in the Third World. And the increasing acreage devoted to corn for ethanol means less land for other staple crops, giving farmers in South America an incentive to carve fields out of tropical forests that help to cool the planet and stave off global warming.

So why bother? Because the whole point of corn ethanol is not to solve America's energy crisis, but to generate one of the great political boondoggles of our time. Corn is already the most subsidized crop in America, raking in a total of $51 billion in federal handouts between 1995 and 2005 -- twice as much as wheat subsidies and four times as much as soybeans. Ethanol itself is propped up by hefty subsidies, including a fifty-one-cent-per-gallon tax allowance for refiners. And a study by the International Institute for Sustainable Development found that ethanol subsidies amount to as much as $1.38 per gallon -- about half of ethanol's wholesale market price.

Three factors are driving the ethanol hype. The first is panic: Many energy experts believe that the world's oil supplies have already peaked or will peak within the next decade. The second is election-year politics. With the first vote to be held in Iowa, the largest corn-producing state in the nation, former skeptics like Sens. Hillary Clinton and John McCain now pay tribute to the wonders of ethanol. Earlier this year, Sen. Barack Obama pleased his agricultural backers in Illinois by co-authoring legislation to raise production of biofuels to 60 billion gallons by 2030. A few weeks later, rival Democrat John Edwards, who is staking his campaign on a victory in the Iowa caucus, upped the ante to 65 billion gallons by 2025.

Go ahead and read the rest, biofuels bitches! It's the answer to all of our problems... or rather isn't.

The most seductive myth about ethanol is that it will free us from our dependence on foreign oil. But even if ethanol producers manage to hit the mandate of 36 billion gallons of ethanol by 2022, that will replace a paltry 1.5 million barrels of oil per day -- only seven percent of current oil needs. Even if the entire U.S. corn crop were used to make ethanol, the fuel would replace only twelve percent of current gasoline use.

Another misconception is that ethanol is green. In fact, corn production depends on huge amounts of fossil fuel -- not just the diesel needed to plow fields and transport crops, but also the vast quantities of natural gas used to produce fertilizers. Runoff from industrial-scale cornfields also silts up the Mississippi River and creates a vast dead zone in the Gulf of Mexico every summer. What's more, when corn ethanol is burned in vehicles, it is as dirty as conventional gasoline and does little to solve global warming: E85 reduces carbon dioxide emissions by a modest fifteen percent at best, while fueling the destruction of tropical forests.

But the biggest problem with ethanol is that it steals vast swaths of land that might be better used for growing food. In a recent article in Foreign Affairs titled "How Biofuels Could Starve the Poor," University of Minnesota economists C. Ford Runge and Benjamin Senauer point out that filling the gas tank of an SUV with pure ethanol requires more than 450 pounds of corn -- roughly enough calories to feed one person for a year.

Thanks in large part to the ethanol craze, the price of beef, poultry and pork in the United States rose more than three percent during the first five months of this year. In some parts of the country, hog farmers now find it cheaper to fatten their animals on trail mix, french fries and chocolate bars. And since America provides two-thirds of all global corn exports, the impact is being felt around the world. In Mexico, tortilla prices have jumped sixty percent, leading to food riots. In Europe, butter prices have spiked forty percent, and pork prices in China are up twenty percent. By 2025, according to Runge and Senauer, rising food prices caused by the demand for ethanol and other biofuels could cause as many as 600 million more people to go hungry worldwide.
