The Ethanol Scam

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.

The third factor stoking the ethanol frenzy is the war in Iraq, which has made energy independence a universal political slogan. Unlike coal, another heavily subsidized energy source, ethanol has the added political benefit of elevating the American farmer to national hero. As former CIA director James Woolsey, an outspoken ethanol evangelist, puts it, "American farmers, by making the commitment to grow more corn for ethanol, are at the top of the spear on the war against terrorism." If you love America, how can you not love ethanol?

Ethanol is nothing more than 180-proof grain alcohol. To avoid the prospect of drunks sucking on gas pumps, fuel ethanol is "denatured" with chemical additives (if you drink it, you'll end up dead or, at best, in the hospital). It can be distilled from a variety of plants, including sugar cane and switch- grass. Most vehicles can't run on pure ethanol, but E85, a mix of eighty-five percent ethanol and fifteen percent gasoline, requires only slight engine modifications.

But as a gasoline substitute, ethanol has big problems: Its energy density is one-third less than gasoline, which means you have to burn more of it to get the same amount of power. It also has a nasty tendency to absorb water, so it can't be transported in existing pipelines and must be distributed by truck or rail, which is tremendously inefficient.
