Fuel price seems to be the subject that always makes headlines on a regular basis. The United States is the biggest consumer of energy in the world. Lucas Davis, a Berkeley Professor conducted a study in 2013 on global oil consumption and found that the average American consumes more than 300 gallons of gasoline annually. The amount is at least 200 gallons more than other developed countries such as Germany, and France. (Davis, 2013) The high consumption forces Americans to rely on foreign fuel sources since domestic energy is simply not enough to satisfy the thirst. Rising fuel price coupled with fuel shortage scare are often a common concern for every American, thus there needs to be an invention to stretch the supply in case of disaster. …show more content…
As green as ethanol may seem to be, its production is very much opposite. In fact, it takes 70 percent more energy to make ethanol than the actual energy content of ethanol itself (Segelken, 2009).
One of the primary purposes of ethanol is to save money for American by stretching fuel supply while easing financial pain at the pump. Ethanol, however, is far from fulfilling that promise. According to the Department of Energy, vehicles that operate on E85 (a gasoline blend with 51% - 85% ethanol) gets 15% - 27% lower mileage than its pure gasoline counterpart. Not only that, E85 is also more expensive per mile than an unadulterated gasoline. (Ethanol, n.d.)
Perhaps one of the most overlook side effects of ethanol is water retention. There is as much as 0.5% of water by volume in E10 gasoline (Rand, 2003); water is the biggest enemy of internal combustion engine since it can corrode fuel line and engine components. The problem is often negligible initially in newer vehicles, however, a prolong use can result in degraded performance and equipment failure. Older vehicles and outdoor power equipment are even more susceptible to damage since they are not setup to use this type of blended

Ethanol did not become such a staple addition to gasoline until the 1970s due to fuel shortage scare. Its use became even more prevalent in the early 2000s with the increase in global warming awareness. The Renewable Fuels Association reports that the United States alone produced over 15 billion gallons of ethanol, a 14 billion gallons increase from its production in 1999 (Industry Statistics, 2017). While ethanol is a clean energy when use, however, its production is not quite as clean clean as it appears to be. Ethanol is considered renewable since the heartland of the United States grows so much corn annually to supply the plant. The corn growing process is quite damaging to the environment. Farming equipment runs on diesel fuel, which directly contributes to the greenhouse gas production. The use of fertilizer and insect repellent chemical is harmful to soil and atmosphere. The transportation of crops relies heavily on semi-tractors that still heavily rely on fossil fuel, thus exacerbate the problem. Not to mention that ethanol plants require electricity primarily generated by coal-fired power plants since it is much more efficient and a lot cheaper. All these factors contribute to the global warming problem, the very problem that ethanol is supposed to
Switching from the expensive oil to alternative fuels has moved from a dream to reality. Today, there are dozens of alternatives to oil that are currently available us to be used. One alternative to oil that is being used more today is ethanol. Derived from plant materials, ethanol can be a cheaper, cleaner alternative to the gasoline that our vehicles run off. When going to gas pumps, one will notice that much of the gasoline is up to 10 percent of ethanol. According to our text, most ethanol in the U.S. is made from corn, yet ethanol can be made from any biomes-- including garbage. (Turk & Bensel, 2011)
The higher price of ethanol in many areas is made worse by ethanol’s second disadvantage that it, regardless of the price you pay for it, contains less fuel efficient energy than gasoline. In short, this means cars won’t travel as far on a tank of gas, and most cars fuel economy will decrease by 20-30 percent. This is very
Ethanol is the fuel of the future. Really? How so? Ethanol will solve the energy crisis. That sounds a little far fetched. Ethanol stimulates time travel. Alright, that’s just a flat-out lie. It seems that these days everybody and their brother thinks that ethanol is the magic key to the future of powering automobiles and solving the problem of dependence on foreign oil. Well, that is not the case. Ethanol is not the energy source of the future; in fact ethanol only creates more energy problems.
Professor Don Hofstrand at Iowa State University says "…a 100 million gallon ethanol biorefinery will reduce [greenhouse gas] emissions by approximately 400,000 metric tons of carbon dioxide equivalents per year." Although ethanol requires greenhouse gases to be emitted for production, ethanol fuel's net emissions are fifty-four percent less than gasoline. Half of the emissions related to producing ethanol are related to growing crops, while the other half is contributed to refining the fuel (Hofstrand). The burning and production of ethanol combined has a smaller carbon footprint than petroleum fuels. This makes it a good fuel substitution while even greener forms of energy are developed to power automobiles and machinery. Reduced greenhouse gases can help slow climate change.
However, despite its many advantages biomass still has many disadvantages. Firstly it is not as efficient as fossil fuels, for example the ethanol produced for cars via biomass is not even close to the efficiency of petrol and does damage to engines over time. It also has the potential to harm the environment through increase of methane gases which are produced as a bi-product if animal and human waste is used. Biomass also requires a large distance away from residential areas in order to burn it and a large amount of fuel in comparison to other energy sources which can have dramatic effects if large portions of forests are cut down to provide lumber.1
One of our sources said that alcohol burns really good and produces little CO2 and no odor. According to our results, not only is it really efficient, but it had no odor nor did we notice the same amount of emissions as gas and diesel. The diesel performed the least, but research has shown that diesel performs greater with different engines. The engines are engineered to have better traction, thrust, etc. that makes the diesel better. So, gasoline was the only real competition for the alcohol. Gasoline lasted a little less than a minute and alcohol lasted a little more than a minute, and gas heated the water less than the alcohol. Gas is barely better per second, but long term alcohol performs better. The literature points to alcohol performing better and the next breakthrough in alternative
Ethanol is an alcohol fuel, and it is safer than gasoline because it is nontoxic and biodegradable, similar to biodiesel. Similar to gasoline though, it is highly flammable. It is even more safe because of the fact that if it is spilled, it can break down quickly into different harmless substances.
Well we all know that the energy system is very unstable because the total energy available on the earth is limited, and man has exploited all the conventional technologies to fulfill his needs. By the use of these conventional technologies, the world also has a disability, with problems such as global warming. Consumption of energy by man increased gradually as his wants also increase. The conventional energy resources mainly include fossil fuels, but research shows that this fuel source will be depleted completely in approximately 20-25 years. This could cause major setbacks around the world. As a result, we need an alternative source of fuel that could keep the world running on its wheel. One possibility is ethanol. Chemically extract
For me, Tulane University is a legendary institution. My father received his Bachelor of Science from Tulane in 1977, and graduated from Tulane Medical School in 1981. My brother currently attends Tulane Medical School, and my sister is an internal medicine resident there as well. My family has deep Tulane roots, and these roots have framed my life. From what I’ve seen, Tulane obviously provides an atmosphere, not only conducive to learning, but also to individual growth – an environment that fosters camaraderie and family.
Cultures across the world differ in just about everything. Why would leadership be any different? While listening to Sayaka Isoda, from Japan, and Ali Al-Tameemi, from Iraq, I saw just how different their countries were from the United States. These differences led to differences in leadership between the three countries.
As time progresses, the use of ethanol in fueling our planet is vastly increasing. The U.S. Department of Energy explained the strong presence of ethanol in saying, “The use of ethanol is widespread, and approximately 97% of gasoline in the U.S. contains some ethanol.” (U.S. Department of Energy, 2016) But the hang up in this is noticing that only 10% of the ethanol is actually utilized, while the other 90% is gasoline. So, the question begs, can we slowly increase this ratio in favor of ethanol? The U.S. Department of Energy suggests the use of Flex-Fuel as an option. Flex Fuel is a higher use of ethanol percentages that normally seen in fuel usage. The Economic pushback is that ethanol yields 27% less energy than full-on gasoline usage. In
People travel from many parts of the world to view the great architectural structures Greece has to offer. They are not only intrigued by the beauty of the buildings but also by their complex development. Greeks’ tradition of building structure came from the ideas of Philosophers such as Thales,Pythagoras, and Archimedes, who questioned their being and challenged their world to find meaning to certain practical applications. From their inquisitions, the Greek Philosophers developed basic but complex strategies that served the purpose of a foundation to many other technical advancements.
The chemical formula of ethanol is made up of 2 carbons, 6 hydrogens and 1 oxygen and is classed as an alcohol (Material safety data sheet, 2001). Ethanol has a boiling point of 78.5c, density of .789 and a molecular weight of 46.0684mol (Biofuels Association of Australia, 2015). Ethanol is now usually used as a fuel for vehicles in its pure form as a replacement for gasoline, where it is blended with gasoline to improve vehicle emissions and power (Biofuels Association of Australia, 2015).
This essay will first discuss the advantages of using corn ethanol as the main source of fuel in the future, such as the renewable features of corn itself, and the benefits of using corn ethanol as an additive of gasoline instead of using gasoline alone. However, everything has its strengths and weaknesses. Therefore, the second part of the essay will discuss some of the weaknesses in applying the fuel into practical usage. For example, corn ethanol currently encounters technical limitations serving itself as a standalone fuel, meaning that corn ethanol can only function by combining itself with a certain amount of gasoline, while gasoline is a kind of fossil fuel. Lastly, this essay will conduct a comparison with other renewable resources in the world, including solar power, other biofuels, and hydrogen fuel.
What environmental benefits do we receive form an influx in ethanol as an alternative fuel? First let’s look
