Who knew Stephen King was a prophet?

No, I’m not talking about the demon-possessed hot rods (I think we all saw that coming). I’m talking about America’s zombie-like loyalty to a certain cash crop — one that has turned our entire nation into the children of the corn.

Lately, of course, you can’t watch, read, or listen to the news without someone touting the benefits of corn ethanol and how it’s the key to leading us on a path of energy independence.

There might be a *cough* kernel of truth to that argument, but… (sorry, I suffer from a cousin of Tourette’s that requires me to uncontrollably shout out useless puns)…

Seriously, corn is not the answer. It’s not even a major part of the answer. In fact, it’s a major part of the problem.

What do I mean? Well, lend me your *cough* ear (jeez, the medication is wearing off quicker)…

In January, USDA researchers completed a five-year evaluation of another biofuel feedstock with the potential to make a serious dent in US petroleum usage. In the largest study to date, switchgrass has been shown to produce 540% more energy than was used to grow, harvest, and process it into cellulosic ethanol, while reducing greenhouse-gas (GHG) emissions by 94% when compared to gasoline.

USDA geneticist Ken Vogel commented that the study demonstrates switchgrass’s potential to be a major renewable biofuel that reduces GHGs and could “potentially displace 30 percent of current U.S. petroleum consumption.”

What if you could use plants to turn industrial waste sites into fertile, productive cropland? Better yet, what if you could produce biofuels in the process? By marrying bio-remediation and crop production, a group of Carnegie Mellon University graduates hopes to do just that: produce biodiesel and ethanol on reclaimed land.

"It’s a proven technology, but in an unproven environment," said Mr. Butcher, 27. "The idea of growing energy crops is

Shirley: Color me cynical, but when giant agribusinesses fall over one another in a rush to board the corn ethanol train, I tend to view the situation with something other than rose-colored glasses.

Outside of the juicy profits awaiting corporations like ADM thanks to the combination of U.S. farm subsidies and $60-plus-per-barrel sweet light crude, the ethanol frenzy offers more questions than answers. First, there is the questionable energy payback: [...]
