The price of gas going up is one thing, but when you add ethanol in the mix, it becomes a double wammy!
Here's a good article about ethanol from a reporter named Halperin who is a reporter for BusinessWeek Online in New York.

Doesn't producing ethanol on a large scale use a great deal of energy?
Yes. Some ethanol skeptics have even argued that the process involved in growing grain and then transforming it into ethanol requires more energy from fossil fuels than ethanol generates. In other words, they say the whole movement is a farce.

There's no absolute consensus in the scientific community, but that argument is losing strength. Michael ****, a scientist at the Energy Dept.-funded Argonne National Laboratory for Transportation Research, says "The energy used for each unit of ethanol produced has been reduced by about half [since 1980]." Now, **** says, the delivery of 1 million British thermal units (BTUs) of ethanol uses 0.74 million BTUs of fossil fuels. (That does not include the solar energy -- the sun shining -- used in growing corn.) By contrast, he finds that the delivery of 1 million BTUs of gasoline requires 1.23 million BTU of fossil fuels.

Producing ethanol could get more efficient soon as new technologies help farmers get more corn per acre of land and allow ethanol producers to get more of the fuel from the same amount of corn. The companies developing new corn technologies include chemical giant Dupont (DD) and Monsanto (MON), which sells genetically modified seeds as well as chemicals for protecting crops.


Is ethanol cheaper than gas?
Surprise, surprise, it isn't. The move this spring by more regions to use ethanol means that demand has spiked, driving up prices. On Monday, the New York harbor price was around $3 per gallon compared with about $2.28 for gasoline (before being mixed with ethanol). In other words, for now ethanol is helping to increase prices at the pump, not to push them down.

So ethanol production and distribution are also controlled by market forces, right?
Only to a certain degree. In addition to heavily subsidizing the ethanol produced domestically, the U.S. government levies a 54 cent per gallon tariff on imports from other countries, such as Brazil, a lower-cost producer. This, of course, discourages the U.S. from importing cheaper ethanol.

Why not eliminate the tariffs?
Well, the idea behind the tariffs is to foster domestic production of ethanol. But amid the ongoing furor over high gas prices the idea of repealing the levy has gained momentum in Washington. Though it would probably annoy ethanol producers like agricultural giant Archer Daniels Midland (ADM), removing the tariffs could have some benefits. It would help ease price pressures and would likely encourage Brazil to boost its ethanol production. However, it's probably not a short-term solution.

Brazil is undergoing an ethanol revolution far more drastic than that in the U.S. Flex-fuel cars which can run solely on ethanol are widely available and the ethanol supply is short enough that the government recently reduced the mandatory ethanol content in gasoline from 25% to 20%.

"Brazil is the model" for how ethanol can be brought into use, wrote Citigroup (C) analyst P. J. Juvekar in a recent report. But while buying ethanol from Brazil could be useful in the future, it's not going to reduce the pain of a road trip this summer.

What companies stand to benefit from increased ethanol use?
There is a crop of American ethanol producers. ADM is by far the largest, pumping out about one-quarter of the U.S. total. MGP Ingredients (MGPI) is one of the many smaller companies involved. Verasun Energy and Aventine Renewable Energy, two other producers of note, have recently filed to go public.

What can we expect to change in the future?
At present commercial corn-based ethanol comes from corn kernels. One of the more exciting ethanol prospects on the horizon is cellulosic ethanol, which can be made from a number of plant by-products, including cornstalks. Although it's unlikely to be commercially available for at least a few years, cellulosic ethanol eventually could help substantially reduce costs. In other words, your car in the future could run on the refuse of farms across the U.S.
