Nothing can break down faster than a technology supported 100% by government, 50% by industry and 10% by reason. Which is why the ethanol industry in America is suddenly looking to be on shaky ground. It seemed like a godsend a couple years ago: Replace foreign oil by helping local farmers and reducing greenhouse emissions! WHERE DO I SIGN!
Politicians loved it, and so subsidies were thrown at producers and ethanol is booming. Unfortunately, it turns out to not be the silver bullet that everyone hoped it would be. And featured this week in three of the four magazines I receive in print form are stories pointing out some of the weaknesses of our current bio-fuels situation. 
The Economist published a story entitled (no, I'm not kidding) Ethanol Schmethanol, which points out some of the limitations of the fuel itself, while National Geographic's cover story "Green Dreams" bemoans the inefficiency of the current ethanol system. Finally, WIRED's cover story hits on much the same topic, but from a more technical perspective, with a focus on cellulosic ethanol and switchgrass.
Long story short? Corn ethanol isn't working. It's inefficient, reduces supplies of actual food which actual people need to actually eat, and increased demand is only leading to the destruction of the last untouched American prairie lands. But solutions might be on the way in the form of cellulosic ethanol, which is much more energy efficient (though more expensive) to produce, as well as alternate forms of biofuels that are more energy dense and gasoline-like than ethanol (namely butanol.)
So don't give up on biofuels yet...but certainly, beware of corn ethanol. If the burst in legislation surrounding it teaches us anything, it's that our government can act on good ideas. We just have to hope that they continue to support alternative biofuels that are more intelligent and actually have science (and logic) behind them.

The following, as a good Canadian lad, makes me like this solution less...
Ethanol's new victims: beer drinkers
We witnessed the tens of thousands of demonstrators decrying the rapidly (and exorbitantly) rising price of corn in the "tortilla protests" in Mexico City earlier this year. The protests came about as a result of the growing demand for corn-based ethanol, the Bush administration's biofuel of choice. But now there appears to be a new dietary staple under threat from the rising demand for ethanol: German beer.
Der Spiegel Online reports that a 2006 barley shortage will raise the wholesale price of German beer this May. Many brewing industry lobbyists attribute the price rise to farmers forgoing barley for corn in order to satisfy the global demand for biofuels, especially from the United States. In the past year, the price of barley has doubled on the German market, from €200 to €400 per ton.
But it's not just Germany that is set to see soaring beer prices. The chief executive of Heineken (the Dutch brewer) warned in February that the expanding biofuel sector was starting to cause a "structural shift" in European and U.S. agricultural markets, which could precipitate a long-term upward shift in the price of beer. Already, futures prices for European malting barley have risen since last May by 85 percent to more than €230 a ton, and barley production in the United States has fallen to 180.05 million bushels (in 2006)—the lowest level since 1936. Global stockpiles of barley have shrunk by a third in the last two years. All of this augurs ill for beer drinkers, who may soon be paying significantly more for their pints.

One thing to note about the way the U.S. Gov jumped on the ethanol train: The Corn Lobby. U.S. corn has been subsidized by the government for years, since it supports a lot of people, but is nutritionally more or less worthless. The move to whole grain and such in the recent past has beaten it down, and the endless march of corporate tech keeps driving down the price.
Ultimately, ethanol seemed a great answer--do something actually useful and shut up the lobbyists for a while...

That's 160%, if they had only considered that their figures were so ridiculous they might not have launched the ethatnol revolution with such a cavalier attitude.

There are other uses for dent corn, and the one we are focusing on here is making ethanol. Its also refined into human consumable food products (like corn tortillas/chips, corn syrup that goes in your soft drinks, etc). The other type is popcorn, which account for about 0.5% of corn production.
Here's a nice site that breaks it down for you. http://www.ngfa.org/trygrains_corn.asp
I guess my point is, using up a bigger chunk of corn for ethanol production most directly affects the cost of feeding livestock. The vegetarians among us may think that's good, but I love my steak, and that very well be a place where we see prices continue to climb. It really does have a ripple effect. More corn production means less soy bean production (they grow in the same area of the country). So, soy bean prices are also going up due to the lower supply. Guess where biodiesel comes from?

1. it is more expensive than gasoline (for now)
2. it is being heavily subsidized by the government
3. tequila prices are going to rise since mexican farmers are plowing under their agave crops for corn crops (they get more money for corn!)
4. food prices will become more expensive
5. it is more energy expensive to create/refine it than gasoline
corn is not the answer, despite what politicians will tell the idiots that live in iowa.

Global warming is only going to be exacerbated with the destruction of natural (which usually means more productive and more carbon-fixing) habitats to support monocultures of biofuel crops. And that's not to mention the massive loss of biodiversity that the destruction is already causing across the world.
Biofuel is not, and I repeat not, a viable alternative to using fossil fuels. We must try harder to find workable alternatives with hydrogen fuels or abiotic power.
