Urging Congress to Cancel the Ethanol Tariff
reporter writes "The Wall Street Journal is urging Washington to discard the 54-cent-per-gallon tariff on imported ethanol. This tariff is effectively a subsidy for corn-based ethanol produced in the USA. Yet, producing ethanol from corn is highly inefficient and consumes 1 unit of energy for each 1.3 units of energy that burning ethanol provides. By contrast, ethanol derived from sugarcane (which is the sole source of ethanol in Brazil) yields 8.3 units of energy. Sugercane is about 7 times more efficient than corn. Some studies even show that corn yields only 0.8 unit of energy, resulting in a net loss of energy."
I'm not too impressed by arguments that say that energy efficiency is the only reason that ethanol or biodiesel can't work. Even if they consume more energy to produce than they make, they are still very useful for one major reason: they are easily transportable. If I can make electricity at $0.07 per KWh at a coal or nuclear plant and make it into a much more valuable transportable energy source via the ethanol or biodiesel route, then I may come out ahead even after the energy losses. Coal and nuclear power are cheap. Gasoline isn't.
Of course, I should mention, you probably shouldn't be running your tractors and other equipment that you use to harvest the corn or other agricultural product with oil or ethanol. That doesn't work. It only works if you have a mostly electrical system. I wonder if there are any major piece of agricultural equipment that can be set up to "run from the grid" in a sense. Like big batteries on tractors that recharge every day?

While this is an important issue, I'd like to see corn lose its protection as a sweetener as well. High fructose corn syrup has replaced sugar as the primary sweetener in our (American) diet, and the studies suggest that HFCS is really quite bad for us. Not only is it a sugar (with all the inherent health issues), but your body doesn't seem to count it when it comes to curbing hunger, so HFCS calories don't replace, but add to, the rest of our diet.
Not to mention cane sugar tastes better. If you'd like to compare, next time you see an old-fashioned bottle of soda, check and see if it's from Mexico. They still use sugar (check the label to be sure), and compare it with the flavor of a domestic bottle of the same brand. You might be surprised at how different sugar and corn syrup taste as a sweetener.
Just imagine, there's an action our lawmakers could take that would help curb obesity, diabetes, fuel prices, and pollution!
Why does it have to be corn versus cane? Has anybody done a study of the engery density of sugar beets? They grow an a northern clime (like Wisconsin or Idaho or Germany), the tubar yields high surgar content, and the waste (both foilage and mash) can be used for compost or animal fodder. What kind of engery density can you get from that? They would be socially responsible because they are grown in developed countries, produce only reusable waste, and would not be produced by peasants toiling in slave labor. They also would most likely be grown on existing agricultural land instead of slashed-and-burned rain forrest. As part of the US's screwed up agricultural price support system, we pay farmers *not to grow* extra corn and soy. Perhaps we can take all that fallow agricultural land and have them grow sugar beets instead.
