Essay three was about my research into Ethanol in our fuel supply. This last paper is an expression of my thoughts based on that research.

This paper is part two of a study on the effects of Ethanol on our economy, and on the environment. The first paper was intended to reflect the results of research I had done into this topic, and this paper is intended to present my personal findings based on that research.
When Ethanol first became available, I was very excited about it. I was in my late teens, and was very happy that we had an alternative to oil for our fuel. I have always, and still do, believe that it is important to loosen the grip of foreign oil producers on our economy. It is good business to have an alternate supplier, in case something goes wrong with one of them. This thought is reflected by our own Government, in a statement from the U.S. Department of Energy Web Site (http://www.afdc.energy.gov/afdc/ethanol/benefits.html), “Ethanol is a renewable, largely domestic transportation fuel”. They make this statement as an opening to pointing out that Ethanol helps to reduce our dependence on foreign sources of oil, and helps to support the U.S. agriculture sector. Even if this was not about ‘foreign’ oil, I believe that demand for energy can only increase, and there is a limited supply of oil. Therefore, a replacement needs to be found. Maybe we will not run out tomorrow, but it is better to find the replacement before we need it.
Another factor that has been on my mind over the last decade or two, is the continually shrinking number of jobs in our economy. I was not predicting our current situation, but never the less, we have hit a bad time, employment-wise. Therefore, if we can produce fuel domestically, this could be a real boon to the economy. The Ethanol Industry via the American Coalition for Ethanol (http://www.ethanol.org ) indicates that the increased domestic production of Ethanol leads to more American jobs, and a boost to our economy. In addition to the jobs created in the production of Ethanol, there are the by-products of Ethanol which will lead to additional manufacturing jobs, and additional products to help fuel the economy.
The environment is the third leg of the argument to support the use of Ethanol in our fuel. I will save the discussion of the legitimacy of Climate Change for a little later. However, I will state now that regardless of Climate Change, I believe there is no point in producing more pollution than necessary. We should attempt to act in a responsible manor when it comes to how much waste we produce, and how we dispose of it. We can never really throw anything out, we can only put it somewhere else on the planet (unless we start launching it into space, that is). Therefore, we will eventually have to face the problem again, at some point in our future, unless we deal with it right away.
In “Clearing the Air with Ethanol” (by Brett Hulsey and Brooke Coleman, published by REAP – Renewable Energy Action Project), They cite a study conducted by the Wisconsin Department of Natural Resources , in which they claim there is evidence of a 16% drop in Ozone exceedance days since the adoption of 10% ethanol (E10) in 1994. The Department of Energy Website, along with many other supporter of Ethanol point out that since Ethanol is distilled from plant material, CO2 produced by burning Ethanol is absorbed by the plants while they are growing. The argument is that the net production of CO2 would be negative.
We have seen many of the arguments that support using Ethanol in our fuel. It offsets the need to import fuel (oil), it promotes American jobs, it has secondary markets (by-products), and it may be better for the environment. Now, I want to look at a few of the arguments against Ethanol. One of the biggest arguments I could find was that Ethanol still uses a lot of fossil fuels in its production.
According to the New York Times, in an article titled ‘ A Range of Estimates on Ethanol’s Benefits’, published June 25th, 2006 (http://www.nytimes.com/2006/06/25/business/25ethanolside.htmlom/), more energy is consumes to make a gallon of Ethanol, than you can get back out of that same gallon. Natural gas is used to produce fertilizers to grow the crops, diesel is used in the farm machinery, and then natural gas, or sometimes even coal is used to run the plants that distill the ethanol.
In the paper “The Rush to Ethanol: Not All Biofuels Are Created Equal”, published jointly by Food & Water Watch, and The Network for New Energy Choices, (available for download from http://www.newenergychoices.org/uploads/RushToEthanol-rep.pdf) environmental concerns are raised. Intensive harvesting may lead to soil erosion. The heavy use of fertilizers and pesticides can lead to further air and water pollution. There is already concern over an area of the Gulf of Mexico referred to as the ‘Dead Zone’. This area is thought to be caused by all of the farm pollution already coming down the rivers into the Gulf.
The current supply of Ethanol is no where near large enough to replace our current need for oil. There is a race to create more farmland, all around the world the ‘Rush to Ethanol’ document also points out all of the land that is being converted. We are loosing farmland that used to be dedicated to food crops, as well as rain forests. On page 21 of this report, they cite a researcher from the University of Minnesota, who points out that if you were to convert every corn and soybean field in the United States to bio-fuel production, you could reduce gasoline usage by only 18%. If we loose native forest land (rain forest, or regular forest), to the production of Ethanol, are we really improving the environment?
The Ethanol refineries themselves may be a cause of pollution. According to an article titled “Ethanol comes with environmental impact, despite green image” published May 5th of 2007, in USA Today (http://www.usatoday.com/money/industries/environment/2007-05-05-ethanolenvironment_N.htm), Ethanol plants produce a great deal of ozone, which is a known health risk. Some Ethanol plants are granted permits to produce over 450 tons of various pollutants.
The final point on the environmental arguments against Ethanol addresses the water usage. Water is becoming a real concern in many parts of the world. In the article I mentioned earlier, “The Rush to Ethanol”, on page 29, The Institute for Agriculture and Trade Policy is identified as estimating that four gallons of water is required for every gallon of ethanol that is to be produced.
I have reviewed the arguments both for and against Ethanol usage in our fuel. Below, I will challenge some of the ideas presented, and provide my own, current views on this topic. First I want to address the topic of domestic production. We have a supply of oil available to us in the United States, but we choose not to use it for a number of reasons. Therefore, if domestic production were the real goal, we do not need Ethanol to achieve that goal. I agree that we should reduce our dependance on foreign sources, but Ethanol is not the only/best way to accomplish that goal. There are new technologies on the horizon that may be better than either oil or ethanol.
In answer to the point about all the new jobs that may be created with Ethanol, I ask about all the jobs that will be lost in the oil industry. The oil may be produced overseas, but much of the actual refining and blending is done here in the United States. There will be a boost in jobs during the period of time that we use both fuels, but if we eventually eliminate oil, we also eliminate the jobs related to oil. In the end, will we really have more jobs? Another argument that was made had to do with secondary markets from the by-products of ethanol. This is good, but what about all the markets that exist for the by-products of the petroleum industry, such as films and plastics, just to name a couple?
On the environmental front, I do find it a bit troublesome that so much land is being cleared for the production of ethanol crops. I think there is a long-term problem brewing here that is not really being looked at. There is some merit to the idea that these crops absorb CO2 during the growth cycle, but it seems to have been ignored that the same plants tend to release CO2 during their rest period (at night, for example). The plant still consumes more CO2 than it emits, but I do not know that it consumes enough to offset the CO2 produced by the whole process (farming, distilling, burning, etc.).
They study that cites the reduction in Ozone Exceedance Days in Wisconsin seems to want to claim that Ethanol is responsible for that reduction. I would point out tat during the same period, the public has become far more aware of the problems of Ozone, and the state has implemented ‘Ozone Action Days’. Considering these facts, How much effect did Ethanol really have?
The problems associated with farming, such as soil erosion, pesticide, and fertilizer usage, are problems we have with or without Ethanol. The “Dead Zone” in the Gulf of Mexico is not only due to Ethanol crops. However, the demand for Ethanol has required far more production from our limited farmlands, that it has had its own effect.
The food and water issues should not be ignored. As much of the world is attempting to find new sources of drinking water, Ethanol production uses a large supply. Combined with the effect on our food supply, it seems foolish to take food and water out of the hands of people who need it, so that we can burn it in our cars.
It was pointed out that Ethanol plants themselves produce pollution. What is not mentioned in that same statement is that oil refineries also produce pollution. In the same way that I argued that there may be little change in the job market if we converted to ethanol over oil, I also have to ask how the pollution from an ethanol plant may differ from an oil refinery. If I had to guess, Ethanol plants are cleaner than Oil refineries, but the truth requires more research.
So, what is the bottom line? I have pointed out that we cannot count on oil forever. It is not an unlimited supply, and it would be nice to do away with the pollution it causes. However, I do not believe that Ethanol is the replacement that will save us. The total impact of Ethanol on the environment does not appear that much better than oil, especially since it does not appear that it could ever completely replace oil. There are a number of other technologies emerging, which may be better replacements for our fuel. I would recommend that we skip over Ethanol, continue to use oil for now, and develop other technologies, such as fuel-cells, bio-diesel, and more efficient batteries.
