Abstract
Ethanol has a long history of being added to gasoline to increase octane and to help the engine burn cleaner and more efficiently. There are benefits and disadvantages; until technology advances more, the ethanol mix E85 will only be available to those who buy select models that are capable to run on E85. There are numerous costs involved in this technology, due to limited demand and limited technology. Most of the people who own E85-capable vehicles do not fill them with ethanol due to decreased mileage and scarce availability. Now, the federal government is pushing to further advance this technology in hope that it will be promising enough to help the country both on an economic and an environmental level.
Introduction
Ethanol is an alternative energy source that can help to reduce the use of both foreign oil and fossil fuels in general. Ethanol fuel has a long history of use even before motor vehicles were invented. This type of fuel is easily manufactured and can come from numerous sources. Ethanol is a clear liquid made from feedstock, which is organic material such as sugar beets and sugar cane, corn, and trees and grass (How Is Ethanol Made?, 2005, para. 1). To produce ethanol, feedstock is ground up, and the sugar from it is dissolved (How Is Ethanol Made?). If corn or trees and grass are ground up, the cellulose from them must first be converted into sugar (How Is Ethanol Made?). The sugar from the feedstock is fed to microbes, producing ethanol and CO2 (How Is Ethanol Made?). Then, the ethanol is purified to make it ready for consumption (How Is Ethanol Made?).

Henry Ford first pioneered ethanol use in automobiles in 1896 in his horseless carriage (Energy Kids Page, 2007). When he developed the Model A in 1908, Ford engineered it to be a flex-fuel vehicle, able to run on both gas and ethanol (Energy Kids, 2007). Ethanol was then used in both World War I and World War II to increase capabilities. As World War II ended, production of ethanol dropped until the 1980’s when lead was banned as an octane booster (Energy Kids, 2007). In 1978, gasohol was used in some applications, consisting of ten percent alcohol (Energy Kids, 2007). In 1997, automotive manufacturers Ford Motor Company and General Motors began to mass-produce flex-fuel vehicles, or FFVs, able to run on E85, a fuel mix that is 85 percent ethanol and 15 percent gasoline or to just run on unleaded gasoline only (Energy Kids, 2007).

Antarctic’s ice melt and accelerating sea level rise, the growing number of large wildfires, intense heat wave shocks, severe drought and blizzards, disrupted and decreased food supply, and extreme storm events are increasing to happen in many areas world wide and these are just some of the consequences of global warming. The fossil fuel we burn for energy coal, natural gas, and oil plus the loss of forests due to disforestation, in the southern hemisphere are all contributors for climate change. In the past three decades, every single year was warmer then the previous year and the warmest 12 years were recorded since 1998. We are overloading our atmosphere with carbon dioxide and trapping the heat and recently, the carbon dioxide level in the atmosphere reached 400 pmm. Not just environmental issues are rising due to carbon dioxide increase but more and miscellaneous issues are appearing as climate change becomes more severe. For example, regional models and local analyses agree that Mongolia has become noticeably warmer and the climate change effect is damaging their millennial of historic nomadic lifestyle and even came to the peek of extinction. The Mongolian nomadic pastoralists became highly vulnerable to many an unusual climate impacts and extreme temperature fluctuation that have led to inadequate pasture land and loss of enormous number of livestock, often faces hostile environmental conditions that led o entrenched pastoral poverty. This essay focuses on how the climate change impacts the qualitative and quantitative value of indigenous culture and nomadic life style, and how the economy struggles in the magnitudes of massive migration of nomads to urban area while it fails to value t...
With the fuel crisis that is happening in the world today it is now more important than ever to begin the look towards alternative fuel sources. One smart step for the US would be to wean the country slowly off of the gasoline fix and to look into alternative fuels to replace the “never coming back” fossil fuels. It turns out that Ethanol as a hybrid fuel proves to be a notable candidate for this gasoline intervention, per say. Now the United States is currently looking to subsidize fossil fuel alternatives. However, before considering ethanol production as a governmental subsidy, using large amounts of hard earned tax payer money, there has to be many alternative factors that come into play such as making sure the pros out weight the cons as far as environmental benefits and performance output and not to mention looking at the entire matter from an economic or investment perspective. First we need to consider what the ethanol we are talking about actually is and how can we obtain it.
Look out your apartment/house window, a car window and what do you see? You see components of our planet, i.e., clouds, paved streets, buildings, patches of grass, rows of corn or soy beans, and business districts as well as temperate forests. And while what you do see is material and simultaneously simple and complex, it still represents a very limited picture of our planet. Unfortunately, there is strong reason to believe that what we don't see warrants our immediate and concerted attention.
Research has proven that there are serious concerns with E15 gasoline and its effect on motor vehicles. Unfortunately, a majority of car owners have never heard of E15 gasoline and are unaware of the damage it can cause to their vehicles. Changing the quality of gasoline available to consumers without their knowledge is irresponsible and unscrupulous. The fact that the government has chosen to ignore industry concerns pertaining to this new blend of gasoline demonstrates they are not following the accepted rules of morally right behavior and therefore they are guilty of unethical behavior.
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.
For over 100 years, the automobile industry has relied on gasoline as its main source of fuel. Gasoline is a colorless, highly flammable substance used in internal combustion engines. It is a fossil fuel made from crude oil, a natural gas formed from the remains of ancient plants and animals (Webster‘s Dictionary). Gasoline has positively influenced our way of life by providing convenient, on demand transportation. It has created a global economy that moves people and goods faster and more easily than ever imagined (Povey 12). Although a seemingly perfect substance, it has unprecedented flaws. The tremendous political, environmental, and economic problems resultant from the excessive use of gasoline leads to the conclusion that the automobile industry should not continue to rely on this source of fuel.

Introduction:The idea of biofuels is a old concept, reaching as far as the ending of the 19th century. Solid in its idea but flawed in its presentation. Biofuels are a alternative energy to fossil fuels that are made from natural methods such as plants and crops and are key in solving the apparent flaws of fossil fuels. While fossil fuels have been in use for over a century, Biofuels have now risen to the popularity and been exposed to the press. At one point of time biofuel were being considered by some of the most brilliant minds ever in human history such as Henry Ford and Rudolph Diesel who believed that biofuels had the potential to be the new evolution s on only to reappear a century later. Now the world faces the struggles of global warming and the depletion of fossil fuels slowly dimming by day. Throughout the last century biofuels have proven to have a place in our society as a new alternative fuel source. Specializing in Being Natural and healthier than fossil fuels, biofuels have had a rough beginning against its competitor due to key situations such as pricing, Side effects, to fuel power. However the idea was passed on a to the later generations, and continued to pasand prolong usage. However through the last decade they have been highly advertised by politicians and Government officials claiming it to be the future of a powerful working society, and to help in making a new energy free world. Through belief Some even claiming that “By 2050, a new generation of sustainable biofuels could provide over a quarter of the world’s total transport fuel, according to a recent report by the International Energy Agency” (last name). With such improvement biofuels should be the obvious answer to providing a better future to th...
Based on the impacts on a coastal location near point Barrow, Alaska which impacts to the ecological, heath, fresh water and societal life. Increasing temperatures in the next 25 years sea thawing permafrost coastal erosion flooding other climate change. Scientist predict that over the next century the temperature increase will be twice as much over the long term norm as it is now. Statewide average annual temperatures could rise from current levels by as 5 to 13 degrees, an average winter temperature could rise by as much as 22 degrees F in certain locations. Climate change is unavoidable, it’s already under way, and the observable effects are likely to increase with time. In the next century, predict changes of 3 to 10 degrees F. small changes in temperature will cause big changes to life on earth. With planning we can minimize the potential harm from coming changes and in some cases even find opportunities. Most planning for future climate change adaption is simply a matter of addressing current effects of weather extremes. The impacts of climate change are diverse, and vulnerabilities differ across regions and sectors.
Global warming has become on of the most controversial issues in the media today. While most of the Western world countries have generally accepted the premise that man's chemical emissions in the atmosphere can and are affected by the world’s climate patterns, in the United States, the issue has become so politicized with many republicans challenging the science behind the theory. Global warming is a greenhouse effect whereby gases are trapped on the earth’s surface causing it to heat up (Maslin 14). It is based on the worldwide temperature records that have been maintained by human beings through their activities since the 1880,s. In addition, global warming is not only caused by human activities only but also through climate changes in solar radiance. The problem is that, humans continue to contribute to the global warming phenomenon. All citizens should work in reducing human activities that cause global warming and also support the development of nuclear power. Scientists deem that, global warming is mainly caused by human activities which accelerate the natural process by creating greenhouse gases in the atmosphere. Human activities have become a great contribution to the greenhouse effect and this means that climate changes are inevitable. They further argue that, if these activities continue and are not reduced, it will lead to more trapping of energy radiated from the earth and this will likely lead to extreme weather and global warming. Global warming should be at reduced levels or else, it will be catastrophic.
all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that
Global Warming One of the most substantial problems in the world today is global warming. This gradual warming of the earth is in occurrence at an extremely slow rate but it is happening. Many scientists believe that as human’s work and release greenhouse gases into the earth’s atmosphere, it can become dangerous for the long lasting life of humans and our environment. “Unless we take immediate action, the impacts of global warming will continue to intensify, grow ever more costly and damaging, and increasingly affect the entire planet - including you, your community, and your family” (“Global Warming Impacts”).
Global warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. This results in an increased evacuation of greenhouse gases. “Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface while long-wave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases.” (2)
Global warming is one of the most serious issues that the human species face today, yet the majority of the population does not pay attention to it. People are not aware of the dangers and do not care about it much because the main effects will affect the next generation and not themselves. Global warming is happening and it is the reason for changing weather and weather extremes such as earthquakes, floods and wildfires. Global warming is caused by societies lifestyle and these lifestyles destroy the environment and affect the whole world. The use of cars, trains, planes, as well as wasting energy for people’s entertainment has a price; this price is that society is in danger.
