The Ethanol Scam: One of America’s Biggest Political Boondoggles : Rolling Stone
A great piece of journalism detailing why ethanol is NOT the answer to our energy woes.
Nor is all ethanol created equal. In Brazil, ethanol made from sugar cane has an energy balance of 8-to-1 — that is, when you add up the fossil fuels used to irrigate, fertilize, grow, transport and refine sugar cane into ethanol, the energy output is eight times higher than the energy inputs. That’s a better deal than gasoline, which has an energy balance of 5-to-1. In contrast, the energy balance of corn ethanol is only 1.3-to-1 – making it practically worthless as an energy source. “Corn ethanol is essentially a way of recycling natural gas,” says Robert Rapier, an oil-industry engineer who runs the R-Squared Energy Blog.
This is a funny excerpt and metaphor for the problem:
“It’s like trying to solve a traffic problem by mandating hovercraft,” says Dave Juday, an independent commodities consultant. “Except we don’t have hovercraft.”
and a sad but very true endcap:
In the end, the ethanol boom is another manifestation of America’s blind faith that technology will solve all our problems. Thirty years ago, nuclear power was the answer. Then it was hydrogen. Biofuels may work out better, especially if mandates are coupled with tough caps on greenhouse-gas emissions. Still, biofuels are, at best, a huge gamble. They may help cushion the fall when cheap oil vanishes, but if we rely on ethanol to save the day, we could soon find ourselves forced to make a choice between feeding our SUVs and feeding children in the Third World. And we all know how that decision will go.
