I think the issue is that we as a society are so used to not having to pay for what we use in terms of the environment. Our use of gasoline has been artificially cheap at the pump for years. I hear so much against ethanol as a fuel but none of it makes sense when you look at the big picture. Sure corn based ethanol is one of the worst in terms of production efficiency but it's still cheap compared to gasoline. Don't believe me? Consider these points:
1. The most common argument against ethanol is that it takes government subsidies to make it affordable. How much did Iraq war v. 1.0 and v. 2.0 cost us? What if we had used all of that money to develop a pure ethanol infrastructure not based on corn? Why is it wrong to subsidize our farmers yet perfectly fine to send money to Shieks in Saudi Arabia or dictators in Venezuela? How much did the wars cost us in lives? How much did the wars cost us in global esteem? Osama Bin Laden's original motivating factor for attacking the US was his observations of US soldiers in Saudi Arabia during the original Gulf War; Would 9-11 even have happened? These are all costs that don't get factored into the $3.05 per gallon that people are complaining about today.
2. The second most common argument against ethanol is that it is less efficient per gallon than gasoline. This is true when you're running ethanol through an engine originally designed for gasoline. Why is it such a stretch of the imagination to consider that when you run the engine with a fuel that it was not originally designed for, you're not going to get optimum performance? If you were complaining because your turbo charged Saab wasn't getting great mileage and you were filling up with 87 instead of the manufacturer specified 91, people would call you an idiot. The compression ratio of the Impala Flex Fuel is a relatively lazy 9.8:1. Ethanol is over 100 octane. Brazillian Chevies run at a compression ratio of 12:1 on pure alcohol. The Impala Flex Fuel is literally wasting energy in order to maintain compatibility with the gasoline infrastructure. Dial up the compression on the 3.5 V6 and you'd likely not only get more power out of the engine but would probably also return mileage similar to a gas only version. Worked for the Saab BioPower.
3. The third argument against ethanol is that it stresses the food supply. This is true if you base your ethanol infrastructure on corn. The beauty of ethanol is that it can be made from a wide variety of sources. Brazil based their alcohol infrastructure on sugar. There is no global shortage of sugar. In fact sugar producers in the U.S. are doing everything in their power to keep cheaper Brazilian sugar out of our market. Among many other sources, Ethanol can be made from alge and kelp. We have a LOT of coastline in the US and kelp grows along all of it. That is all fuel out there waiting to go into your V8.
4. The fourth argument against ethanol is that it takes oil to produce ethanol. I'm not quite sure what kind of logical defect is at work with this one but it's a duesy. Sure it might take oil to get the ethanol infrastructure in place, but once up and operating, the infrastructure is self sustaining. Why can't the farm tractors, tanker trucks, in fact the entire network be powered by some sort of bio-fuel? Some might argue that it would take more energy input than you'd get with output. While this might be true with corn <the worst source>, it is not true with other ethanol sources, especially those derived from waste products.
In short, if you want to keep your V8 and not drive an Aveo, support ethanol and don't by into the hype against it.... because all it is, is hype.
Raise your hand if you don't want a big American car with a big American V8 with a 13:1 compression ratio that burns 100 octane fuel grown by Americans that costs around $2.35 a gallon and at the same time not have the U.S. participate in more mid-east wars?
