Ethanol is a renewable resource that is produced from many agricultural products. The public attitude towards corn based ethanol is influenced by many different subjects like, the effects of production on the environment, the effects on local economies, and the effects on the national food prices. Focusing on corn based ethanol there are considerations to take into effect such as the benefits of ethanol, the problems or concerns with ethanol, the political involvement with ethanol, and the effect of ethanol on the economy.

The Ethanol Environment Ethanol is a renewable resource that is produced from many agricultural products such as corn, which can be blended into many different proportions of gasoline. The public attitude towards corn based ethanol is influenced by many different subjects. The overall plan for ethanol was good but took a wrong turn and has caused damage as a result.

As stated by Michelle Heath, “there are no known environmental hazards that have to do with ethanol.” Ethanol does not only make our vehicles friendlier to the environmental it also has other impacts. Considering our total energy use, including building, heating and electricity, the savings from the use of biofuels is two-thirds greater than using gasoline (Dewsbury, 2009).

With the increased demand for corn, to produce ethanol, the rise in the extremely low corn prices increased farmers’ incomes. With a demand not only in our own country for corn the increase on taxes for importing corn would also increase farmers’ incomes. Ethanol went beyond increasing the income of farmers planting and harvesting corn. Ethanol can be produced from nonfood plants such as switch blade grass, soybeans, and other grasses. These nonfood plants can be grown on marginal lands with very little input of fertilizers and pesticides. There are many potential environmental hazards connected with the production of corn based ethanol. The byproducts of an increase in growing more corn otherwise known as, planting, harvesting, fertilizing, and the use of nitrogen in this process all posed an increased danger to the environment. The excess nitrogen found in water ways such as lakes and rivers can contribute to algae growth that becomes out of control. The algae cause poor oxygen levels so other marine plants and animal cannot survive. These oxygen deprived areas are called dead zones. Dead zones are not just found in large bodies of water they are found in small ponds, lakes, rivers, and streams. They are caused by the same pollutants, nitrogen fertilizer and pesticides as a result of crop production run off which also leads to severe soil erosion (Erbaum, 2009). This means that ethanol production can also pose a huge risk to aquatic life (Michelle, 2010). During the planting and harvesting process a variety of large equipment are used. These machines require a lot of fossil fuels to plant and harvest the corn crops that are used in the production of ethanol. Not only do they use a significant amount of fuel they also release large quantities of carbon dioxide into the atmosphere (Erbaum, 2009). For the production of ethanol to increase more farm land is also needed. As said by Dewsbury, “Farmers planted 92.9 million acres of corn [2007]-an increase of 14.5 million acres over the previous year….This increase will easily absorb the demand from new ethanol plants. This means that more roads must be built in order to gain access to these new fields and this increased construction causes the release of more carbon dioxide through the use of more fuel (Dewsbury, 2009). Once the corn based ethanol is produced it releases high levels of nitrogen oxide, a key ingredient of smog. Ethanol also poses a huge risk to vegetation contamination if it is ever spilled or indirectly leaks (Michelle, 2010).

The energy required to make one gallon of corn based ethanol takes more than one hundred percent more energy inputs per gallon than into the production of a gallon fossil fuel based gasoline. It also requires the use of 1700 gallons of water, mostly to grow the corn, and 22 pounds of corn just to make one gallon of corn based ethanol. The only way that ethanol can be competitive is if it were to have significant technological advancements (Erbaum, 2009). If the entire corn and soybean crops were used to create ethanol it would only replace eighteen percent of the current amount of fossil fuels used today (Dewsbury, 2009). As Dewsbury states, “Taking apart, fermenting it, distilling it and extruding it uses a lot of fossil energy…We are grasping at the solution that is by far the least efficient.” Not to mention the production of Ethanol using a food source would drastically increase food prices (Marshall). Wheat was also another major factor in the price increase of food. Ethanol production switches wheat and corn out in their off seasons which increases food price (Dewsbury, 2009). This happens because the cows that we eat are usually feed corn so the corn cost more money to purchase for livestock production, so the meat costs more money in the end. Also the fact that poorer countries are now making enough money that they can afford to raise their own cattle and also need grains to feed them. So the shipping and demand of the grains is higher making our food cost more worldwide. With the price of food rising worldwide this leaves the poor countries in a dire situation on how to afford to feed their citizens. They can no longer afford to buy the basic foods they need to feed their population. (Marshall, 2010).

Ethanol when stored in small amounts is quite flammable and in some cases it can explode. It must be stored at temperatures between 10 and 40 degrees Celsius. If it is not stored properly it can become very unstable and dangerous. If ethanol is to catch on fire it cannot be put out with just water. You must put it out with alcohol-resistant foam.

It is also important to note that within the surrounding areas of ethanol production there have been reported health problems. Lead toxicity has been a common problem with children living around or near an ethanol plant. In adults living in an area near an ethanol plant there has been an increase in diagnosed cases of hypertension. The symptoms of the illnesses are headache, irritation of mucous membranes in the upper respiratory tract, drowsiness and inability to concentrate (Michelle, 2010).

At first ethanol producers received government incentives to help get them on their feet. Many people were not happy about what they were receiving and thought that the money could be used elsewhere or be put to better use. Congress then kept supporting them during the recession. They have continued to receive more incentives including, the extension of the blenders’ tax credit and import tariff (Marshall, 2010). The ethanol industry has received subsides and substantial support from the United States government for quite some time. Some people argue that in order to sustain the current economic environment extra support from the government is required. The operating loans guaranteed to ethanol refiners and tax credits for “green” jobs creation or preservation are current sources of support that as the economy strengthens the government will expect to slowly supply a little less money to blenders. But if the economy worsens or the government decides to stop funding ethanol there will be no way for the industry to financially survive (Dewsbury, 2009). The expected total of tax credits that have been given to blenders is close to six billion dollars. The federal support being received now is based on mandated levels of consumption. Financial incentives such as grant and loans, tax credits, tariffs on ethanol imports, and federally funded research and development efforts are part of what is being funded. The Secret Service has also funded ethanol production because they believe that it is part of nation security and could make America safer if we created our own fuels (Erbaum, 2009).

Ethanol receives more federal support than any other renewable energy source on the market. Liquid biofuels is right behind it in their subsidization as it is close to the top for all energy sources. There are over two hundred different types of subsides that ethanol blenders can receive. They don’t just not receive these subsides though. They have to meet standards and production marks as to how much ethanol they must be blending and putting on the market (Dewsbury, 2009).

Critics of ethanol claim that, as a society, we must choose between using our agricultural resources for feeding people or for fueling cars. Although corn prices in America have risen in response to increased demand for ethanol-in part due to governmental support such as the renewable fuel standard in the Energy Policy Act of 2005-we can continue to meet both goals…Furthermore, the productivity of America’s corn farmers has steadily risen over the past three decades…this trend can be expected to continue…combined with greater efficiency in production…American farmer will be able to increase the supply of corn to make up for the expected rise in demand.”

The Unites States Environmental Protection Agency made rules and developed calculations for the life cycle greenhouse gas emissions that will determine which fuel qualifies for Renewable Fuel Standards. These standards will attract a lot of scrutiny if major stake holders are excluded from the ethanol industry. Renewable Fuel Standards mandate that increasing volumes in renewable fuels used must increase by 2012. Some subsides may be lost or decrease in amount of funding provided if the mandates cannot be meet (Marshall, 2010).

The production of ethanol has created a somewhat reliable renewable energy source. With that comes the consequence that the price of food has increased because of the production of ethanol. The demand for corn has become so high that it is hard to keep up with so the price of corn has risen in response and has become difficult for other countries to afford as we want to keep the crop in American so we can use it for our own needs. It has had such a negative effect on the economy that world food prices have increased seventy-five percent since its production in large quantities began (Dewsbury, 2009).

Ethanol is a renewable resource that is produced from agricultural products. Ethanol has many problems and causes for concern, such as with the many subsides it receives, and with the byproducts it releases into the atmosphere and water. Ethanol has become a hot political issue due to the many subsides and blenders tax credits it has now been a recipient of for many years.

...Ethanol Sarah Scott June 24, 2013 Ethanol is an alcohol that, when added to gasoline, can be used as a transportation fuel. It is being blended in to gasoline at concentrations of five percent to ten percent for use in motor vehicles. The main ingredient in ethanol is corn, a renewable resource that is in abundance in the United States. Brazil is the leading producer in ethanol, and vehicles there have been running on 100% ethanol for many years (, 2013). While ethanol seems to be the answer to renewable fuel sources, there are both advantages and disadvantages to using this product. The most obvious advantage of using ethanol is the benefits to the environment. Vehicles that are fueled by ethanol produce much lower carbon monoxide and carbon dioxide than those using gasoline (West. 2013), and because this fuel source is made from plants, the carbon dioxide it does emit is recycled back to reproduce the product. A study published by Yale University's Journal of Industrial Ecology found that GHG emissions from ethanol produced at modern dry-mill facilities are "... equivalent to a 48 percent to 59 percent reduction compared to gasoline, a twofold to threefold greater reduction than reported in previous studies." (, 2013). Another great advantage is that ethanol is readily available in many countries around the world. In the United States, it is made with corn, and produced in the Midwestern states like Nebraska, Iowa and......

...Ethanol Ethanol can provide an alternative fuel source that may be a partial solution to the current energy crisis. Although when is not quite agreed upon, most experts can agree that the world will run out of fossil fuels at some point in time. In turn, this causes a need to search for alternative fuel sources. Is ethanol biofuel a solution and a good alternative? There seems to be more advantages then disadvantages, so yes overall, ethanol is an effective solution. Ethanol is produced from plant matter. The plant matter is broken down into simple sugars and starches and then fermented and distilled into alcohol. Many large farms in the Midwest have planted all or part of their land area to take advantage of the government subsidies which are offered for corn production to supply the ethanol production needs. Ethanol can be used in all cars in low concentrations, such as 10% ethanol. It can be used in specialized cars, trucks and minivans known as “flexible fuel vehicles” in concentrations up to 85% ethanol (commonly known as E85). Fuel stations in the Midwest are offering E85 fuel, often as a lower price per gallon then traditional fuel. There is a lot of controversy on the ethanol biofuel which centers on the cost to tax payers for ethanol subsidies, the environmental concerns focused especially on admissions in the ethanol production process, and the amount of net emission savings. Ethanol contains less energy per gallon than a gallon of gasoline. ......

...Ethanol is an alcohol-based fuel that is made by fermenting and distilling starch crops, such as corn and it can also be made from “cellulosic biomass” such as trees and grasses. A majority of ethanol that is used for fuel is blended into gasoline. More than ninety-five percent of the gasoline supplied in California today contains six percent of ethanol. Flexible Fuel Vehicles, or FFVs, have been produced by United States automakers, which are resulting in a growing market for E85 fuel, eighty-five percent ethanol and fifteen percent gasoline. (Consumer Energy Center, 2006) About two-thirds of the United States petroleum demand is in transportation and approximately half of United States petroleum is imported. With the U.S. depending so heavily on foreign petroleum supplies, we are creating a greater risk for trade deficits, supply disruption and prices changes. The Renewable Fuels Association’s 2012 Ethanol Industry Outlook calculated that in 2011 the ethanol industry replaced the gasoline produced from more than 485 million barrels of imported oil. Ethanol represents twenty-five percent of domestically produced and refined motor fuel for gasoline engines. (U.S. Department of Energy, 2013) Since ethanol has a lower energy content than gasoline, about one-third more ethanol is required to travel the same distance as on gasoline. However, a high octane rating and other characteristics, result in increased engine efficiency and performance. The cost of producing ethanol is......

Ethanol: Is It Really the Best Option

...Ethanol: Is It Really the Best Option Ethanol based gasoline vehicles are becoming more and more popular, but is ethanol gasoline better than regular petroleum gasoline? Ethanol, also known as ethyl alcohol, can be an effective motor fuel, and most of the gasoline in the US contains some ethanol (Ethanol As a Transportation Fuel). Many people everywhere are praising ethanol gasoline because it can reduce pollution, and increase engine performance. There are some facts that are not being recognized, and these facts should be brought to light. The price of corn and food products made from corn will increase from the higher demand of corn and vehicles have to use one-third more ethanol than regular gas. Ethanol gas in the end will end up costing more than petroleum gas being used now. Ethanol gas as an alternative to gas will mean that the demand for corn will become greater and greater. The use of ethanol in motor fuel has increased for years an average of twenty-five percent per year (Ethanol Cost And Environmental Factors). This year America will use 5 billion bushels of corn which will produce about 14 billion gallons of ethanol (Helman). So will farmers be able to grow the amount of corn needed for the production of ethanol gasoline and food demand? The increase in corn crops in the Midwest has added to size of the dead zone in the Gulf Coast (Miller). What if the country was to experience another serious drought, or major flood? A different method of creating ethanol......

Ethanol as a Transportation Fuel

...Ethanol has the ingredient formula C2H5OH. It is the same alcohol found in alcoholic drinks, but ethanol also makes successful motor fuel. There have been decades of motor fuel submission knowledge in the United States and other countries with ethanol. Ethanol used for petroleum is being mixed together into petrol at concentrations of 5 to 10 percent. In certain states, ethanol has replaced (MTBE) as a fuel constituent. Over 95 percent of the petroleum supplied in the state today enclosed 6 percent ethanol. There is a miniature but increasing market for E85 fuel for use in elastic fuel vehicles, more than a few million of which have been created by U.S. automakers. But E85 is first and foremost established in the Midwest in corn-producing states. Ethanol is being used to put together a combine of diesel fuel and as a substitute for leaded aviation fuel in miniature aircraft. Ethanol has a lesser power content than petrol. That means that about one-third more ethanol is necessary to take a trip the same distance as on fuel. But other ethanol fuel distinctiveness, including a high octane rating, consequence in enlarged engine competence and presentation. The 15 percent petrol used to originate E85 is to guarantee cold weather engine opening and to improve flame radiance in case of fire.

I have been aware of corn ethanol production in the United States for a long time. The reason for my awareness is a lot of my family has been apart in the oil industry for a long time. Then I notice every time I go to the gas station that it states “the gas may contain up to 10% ethanol”. These things that have affected my life are the reason I analyzed in greater detail what this article has to say about ethanol. I read one article towards the use of ethanol and one against it.           My journey started with the first article that was assigned to the class: “Energy Balance of Ethanol Even More Favorable Than Estimates” from Usagnet by Alan Tiemann, the Nebraska Corn Board Director. In this article Tiemann talks in great detail about the energy balance of corn production to ethanol conversion is a better measurement and more profitable for both the oil and farming industries. He also states that multiple studies have proven that the conversion measurement is better. The study at the University of Nebraska really stuck out. Ken Cassmann, director of the Nebraska Center for Energy Sciences Research. Cassmann researched and believes that the past researches were based on “backward looking data” and not that true.

Ib 403 Brazil Ethanol Final Paper

...The Brazilian Ethanol Story IB 403, Section 003 Introduction: Biofuel is one of the newest and largest trends sweeping the world. Gaining interest in countries and economies, governments have announced strong commitments to biofuel programs in order to reduce greenhouse gas emissions and diversify energy sources. Although these programs are new to many countries, Brazil has years of experience with sugarcane-based ethanol, creating a success story for others to reference. Currently, Brazil is the largest biofuel market with the United States ringing in a close second. However, Brazil’s ethanol is created from sugarcane while the U.S. uses corn to produce their ethanol. Not only is Brazil’s sugarcane-based ethanol the first renewable fuel to be cost-competitive with transportation fuel, but it is also the most economical compared to its competitors. The ethanol’s efficiency is due to the power of the sugarcane compared to corn as an ethanol feedstock, a perfect climate for sugarcane harvesting, and the large, unskilled, inexpensive labor force in Brazil. In addition, the U.S. uses almost double the amount of land to farm corn to produce ethanol as Brazil uses to harvest sugarcane to produce almost the same volume as ethanol. What is Ethanol? Ethanol is an alcohol fuel distilled from plant materials, such as corn and sugar. Ethanol is the main biofuel for transportation and Brazil is the greatest exporter globally of bioethanol.

...Chapter 9 Ethanol Policy and Ethanol Politics David S. Bullock28 The United States is currently passing through one of the most exciting and controversial periods of its energy history. With the US military caught up in armed conflict in the Middle East, and with global warming looming in the minds of many expert scientists as the world’s greatest environmental challenge, a common belief is that it is more important than ever that the US develop sensible and far-sighted energy policy. Politicians’ claims aside, the politics of energy policy are rarely about what is best “for the country.” When government sets energy policy, some people gain, and others may lose. The politics of energy policy, then, are not simply, or even generally, about how to make the nation as a whole better off. Rather, the politics of energy policy are very much about interested political groups struggling against one another. This type of “special interest” politics is nothing new, and not unique to energy policy. Nevertheless, it is widely held among average Americans that the political activities of special interest politics are often bad for the nation as a whole. Because public information is a democracy’s best weapon against harmful special-interest politics, in this chapter we hope to accomplish three goals: 1) to present an outline of the “nuts and bolts” of U.S. ethanol policy; 2) to use economic analysis to examine the effects of ethanol policy, presenting arguments to cut through much of the...

Alcohol consumption is characterized by excessive consumption which leads to feelings of increased anxiety and other negative emotional states.Consequently, these emotions lead to further consumption.Similar to human alcoholics, ethanol- dependent animals show signs of anxiety like behaviors and self administrate ethanol during periods of withdrawal. CRF, also known as corticotropin releasing factor helps mediate the increased anxiety during withdrawal.Additionally,regions of the amygdala are comprised of the CRF system, although unknown where the specific sites are responsible for the CRF component of excessive drinking. Also, numerous studies have shown that the amygdala is involved in “mediating the behavioral and physiological responses associated with anxiety.” This relates to the general article which focuses on the consumption of drug and alcohol, triggering feelings of anxiety which can be quieted by consuming more of it.Specifically, the amygdala is the part of the brain where the feelings of anxiety are triggered. Moreover, new research is showing alcohol's involvement in the transformation of the chemical architecture of the brain, allowing the brain's stress response to contribute to its dependency.  CRF, also known as the corticotrophin releasing factor, is a chemical that is involved in the......

Determination of Alcohol in Cossack Vodka by Means of Simple Distillation Abstract

...distilled liquor composed primarily of water and ethyl alcohol or ethanol (CH3CH2OH) without a definite aroma or taste. Alcohol is a primary content of vodka, and distillation – a process involving condensation and evaporation wherein solvents of different boiling points are separated from each other – is a method that may be used to determine the certain presence of Alcohol content in Cossack vodka. A certain number (17) of test tubes were obtained, each with 0.05 ml until the temperature reached 93(C. The volume of distillate collected by the end of the experiment was 9.00 ml at 93(C, giving percent ethanol of 30.00 %. I. INTRODUCTION: Distillation is the process of evaporating a volatile substance from a solution of non-volatile substance wherein the vapor afterwards is condensed in the condenser and collected in the receiving flask. Simple distillation is a process of separating two liquids with different boiling points. It can be used to separate liquids with boiling points of at least fifty degree Celsius. There are four types of distillation: simple, fractional, vacuum, and azeotropic. Vodka is a colorless liquid made by distilling fermented substances such as sorghum, corn, rye or wheat. Vodka is said to contain 40% to 55% alcohol. The experiment aims to: (a) separate the components of Vodka, an alcoholic beverage, by the means of distillation, particularly simple distillation, (b) compute for the percent ethanol and percentage loss in alcohol (Vodka) II.......
