Essay: The Ethanol Craze - 5/12/2008
The teacher told us that by the time we grew up, our cars would be powered by these. I think the electric battery was supposed to get us through cloudy days. Sounded great to me. However, that was in the fall of ... 1963, and I have yet to see a solar-powered car.
As far as the solar powered future is concerned, I am running out of time to enjoy it.
The fact of the matter is that we still don’t have an agreed-upon replacement for gasoline. General Motors is once again working hard on an electric car. All the automakers are working on hybrids of some kind. Stan Ovshinsky, the now-retired founder of Energy Conversion Devices in Troy, is betting the future will be hydrogen. Others are betting on corn-based ethanol – at least as a transitional fuel. Then there is so-called cellulosic ethanol, which we first heard about when George W. Bush suggested making fuel out of switch grass.
In Illinois, a company called Coskata says it can make ethanol out of everything from table scraps to old tires. And their arguments were convincing enough to get General Motors to invest. The one thing all these people have in common is that they know the world’s fossil fuel reserves are running out.
Gas and oil are getting more and more costly, and nobody has a clear-cut solution as to what to do next. Actually, these are things we’ve known for decades, but never did anything about them.
Some say the oil and automotive industries did their best to make sure nobody did anything about them. Well, that’s changing now. We may not have one common fuel, at least not for awhile.
And we do need to experiment with as many alternatives as possible. But while I am no engineer, I have serious doubts as to whether corn-based ethanol makes sense.
Our sensible neighbors to the north get it. Monday, the Ottawa Citizen ran an editorial highly critical of the whole idea.
Noting that rising global prices and increasing food shortages have sparked recent riots in Haiti, the newspaper said “Food supply is a complex thing. But it is becoming clear biofuel production is playing a role in shrinking that supply.”
The image of peasants starving so we can fill up our Lincoln Navigators with ethanol-based fuel is not charming. The Ottawa paper suggests refocusing biofuel research towards algae. That sounds good. Making gasoline out of mosquitoes would sound good, too, But whatever we do has to pass two tests:
Will it work? And perhaps more importantly, what damage would it do to the environment and the ecosystem?
We are in a process of transition, and here’s something else they didn’t tell us back in seventh grade.
Whatever we do, it won’t be easy.
