One day I pulled up to a gas station, and to my surprise I saw a new sticker on the pump. The sticker read,” Fuel may contain 10% Ethanol.” I was a little taken back by the sticker. I didn’t have a full understanding of why ethanol was being used in the fuel for my car. I knew that ethanol was a bi-product of corn and other plants, so I found myself asking the question, is corn for food or fuel? I got back into my car and returned to the freeway with this question on my mind. While driving I started noticing stickers and labels on other vehicles that read: CNG (compressed natural gas), Flex Fuel (allows vehicles to go between 2 different fuels), HEV (Hybrid Electric Vehicle), and Bio-diesel (cleaner burning diesel fuel, made from plants or vegetable oils). As I pondered about the various labeling, I found myself most curious about ethanol and other bio-fuel products. I have heard tidbits about the energy crisis or dilemma, but not really enough to gain a strong opinion about the topic. Having a curiosity and a desire to become more informed on the topic, I sent myself to the internet with hope to become more educated. I started with the GOOGLE search engine and input “Corn + Fuel”, and got some very interesting articles and pictures. The first think I saw was a picture that really got me thinking and explains more than I can with words. Seeing this photograph really helped me to evaluate my question, “is corn for food or fuel?” This photo graph shows corn at its’ purest state, showing fuel consumers what they are putting into their cars. I am not saying that ethanol is a bad thing, but does it need to be derived from corn or are there other biomass (plants that can be used for fuels) products that could be used.

Through all my findings and research, I have developed a conclusion to my own question, “is corn for food or fuel?” I can now answer this question with knowledge and reason; Corn is intended for food!

To support this claim, Kingsolver offers multiple statistics that the average American consumer would be unaware of. For example, Kingsolver states that “the average food item on a U.S. grocery shelf has traveled farther than most families go on their annual vacations,” which allows her to bring into light the largest and unexpected economic impact of food: Oil (Kingsolver 4). Fossil fuels “were consumed for the food’s transport, refrigeration, and processing,” and Kingsolver later mentions that “synthetic fertilizers, pesticides, and herbicides use oil and natural gas as their starting materials, and in their manufacturing” (Kingsolver 5). Kingsolver then asserts that our dependence on nonrenewable resources, like the scarce rain in Tucson or the foreign fossil fuels used in food production, needs to end because “we are going to run out of them” (Kingsolver 21).
The U.S. government spends billions of dollars every year subsidizing corn production, livestock feed, processed foods, and ethanol production account for the greatest uses of corn in the United States. Supplying the livestock and processed food industries with cheap corn ultimately leads to an American diet that is heavily based on the consumption of meat and sugary processed foods. This diet is thought to contribute to America’s obesity epidemic. Corn subsidies also encourage production of ethanol. Ethanol may be no better than fossil fuels because of the required energy inputs and the environmental damage caused by its production.
Richard Manning Wrote the essay “The Oil We Eat – Following the Food Chain Back to Iraq” which was published in Harper’s Magazine February 2004 edition. In this essay, Manning discusses the evolution of agriculture and the consequences of it. Furthermore, Manning explores the relationship of fossil fuel, food calories and transfer of energy to illustrate earth’s prospective future. Through the use of charismatically presented factual arguments, visual powerful emotional narratives and the credibility of a few choice names, Manning creates an environment in his essay that allows flaws to escape otherwise unknown to majority reader.
...m fossil fuels, there remains alternative resources that can easily be taken advantage of. So why isn’t the United States taking this deeply into consideration and improving this dilemma? The energy crisis of the 1970’s continues on into the present as Americans search for new ways to fuel the consumption. This remains unresolved.
In the first third of the book, The Omnivore’s Dilemma, by Michael Pollan, he draws the reader in by bringing to light many interesting facts about corn that most individuals may not realize. He states that the majority of food that people consume contains corn. Although people of Mexican descent are usually referred to as the “corn people”, Americans have now surpassed them in the amount of corn consumed in their daily diet. Corn is consumed in a variety of forms and many of the animals that are eaten by Americans, such as the chicken, pig, turkey, and lamb are fed corn. When a person eats these animals, he or she is essentially increasing their corn intake, and in most cases without even realizing it. The corn crop has spread vastly and is massively produced because it is efficient. Unlike other crop plants, corn can survive in harsh weather conditions and it is light and easy to transport. Maize is also self-fertilized and pollinated by wind, and it has evolved over time and continues to evolve, into new forms and new uses.
In conclusion, corn has come a long way since its first domestication. It began as a prized possession to the Natives as they worshipped corn goddesses and had steady rituals allowing them to receive the corn and give thanks for the corn. The views for the United States seem to be produce as much as possible – and profit from it. China and Hungary aim to produce corn as well but limit themselves to unmodified corn. Although all the groups previously mentioned have/had their own way of viewing corn, one thing is for certain: corn is a popular plant and is presently essential to our lives.

In the United States we have been looking into alternative energies to reduce our dependence on oil and help reduce our carbon footprint. One method the EPA has come out in support of is ethanol production. Ethanol is considered a green fuel because it recycles the burned carbon each time new crops are grown. In theory ethanol is a good stepping stone between using gasoline and zero emission power sources. However biofuels are still young technology that has many problems before it can be useful. The EPA is in full support of biofuels and has mandated that by 2020, 36 billion gallons of biofuels are to be produced in America. Currently almost all of America biofuels comes in the form of corn based ethanol which is extremely inefficient and can cause sustainability problems. Due to this reason only 15 billion gallons of the mandated biofuels can be form corn based ethanol. The rest of the biofuel must come from non-corn based alternatives such as cellulosic ethanol which the EPA projects to create all most all of the 21 billion remaining gallons of ethanol. Cellulosic ethanol uses the cellulose that is in all plants matter to create ethanol. Cellulosic ethanol is far more efficient than corn ethanol because you can use the whole plant and it sets no limitation on what type of plant matter can be used. Even though the EPA projects that these number will be achievable, due to current setbacks and efficiencies cellulosic ethanol will not be able to meet this output within the time constraints and a goal of 2034 years would be more realistic in the long run.
Ethanol production was developed in hopes of severing our ties with fossil fuels in favor of alternative energy, such as biofuels. Although, VOCs emissions are released during production of ethanol in a factory, the quality of air is greatly improved when burning ethanol versus fossil fuels. Burning ethanol instead of fossil fuels reduces the amount of cancer-causing greenhouse gases that go into the atmosphere. Ethanol production ranks at the bottom of industrial water usage, but is still not out of the woods with the abundance of water usage needed in corn feedstock and ethanol manufacturing and processing facilities. Many acres of land are needed to grow corn crops, however, many corn farmers are successful in growing more corn on less acreage.
618.3 million metric tons of CO2 equivalent are produced each year in the United States alone for agriculture (EPA). Agriculture is one source of greenhouse gasses we can’t eliminate, but we could as a species decide to eat greener. Cows are a massive producer of methane, but very few people are willing to give up or downsize their stake intake. With so much greenhouse gas produced the problem is compiled when the amount of clean water used is taken into context. “Globally we use 70% of our water sources for agriculture and irrigation, and only 10% on domestic uses.” On the same note of water conservation 783 million people don’t have access to clean water. The issue as addressed isn’t agriculture, but where we invest most of our resources in production (The Water Project). McDonalds would not have been happy if he mentioned this, but a Big Mac produces 6.8 lbs. in greenhouse gas emissions (Ganeshan,
...her combination of intoxicant. There are several better plants to use, sugar cane and algae all produce far more ethanol than corn does. Keep in mind that running on electric sometimes is better than running on gas all of the time, But to see for yourself go down to the car dealership and ask for yourself.
A surprising fact is that most of the corn we produce in the United States is not actually eaten. In 2008 the United States produced a total of 12.1 million bushels of maize. Of that 5.2 million was used as livestock feed, 3.6 million for ethanol production, 1.8 million for exporting, .9 million for production of starch, sweeteners, high fructose corn syrup, and oils, and finally .3 million for human consumption in grits, flour, alcohol, etc.
Some of the ways we try to combat Climate Change differes from region to region and culure to culture. One of the remedies that seems to be adapting all around the world is the use of biofuels instead of using fossil fuels. People believe that instead of digging up and using oil and petroleum, our best solution to combat greenhouse gases emitted by fossil fuels is to plant soybeans, sugar cane, palm oil and use that as a replacement. More cars are flex fuled, and use ethenol mixed with petroleum to lessen the use of oil since oil prices are only going to increase with the decreasing amount that is
...ch is used to replace natural gas. He also stated that, among the equipment used to burn the biofuel, the suspension burner have the ability to exceed 99% efficiency and whole-tree burner can reduce the cost of harvesting and handling woody fuels by about 35% (Brown, 2003). Moreover, the usage of bio-energy in long term is to provide a degree of ecological balance and climate change, avoid acid rain, reduce soil erosion and minimize water pollution (Gevorkian, 2007). Therefore, biomass is environmental friendly like solar energy. Based on the research that has been carried out regarding the synthesis of gas from biomass, the gas gasifies in the internal combustion engine. The relative energy density of synthesis gas is higher than the fossil fuel under certain conditions. In addition, the relative flame speed of synthesis gas can reduce the time for spark ignition.
The concept of this essay is to stress that biofuels are a viable and sustainable energy source than fossil fuels, showing its advantages but not ignoring its disadvantages which also enlightens us about the cleaner and renewable natural resources. Biofuels is an alternative source of energy which can end the global dependence on fossil fuels.
