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 ethanol (ethyl alcohol) an alternative fuel, fermented from corn, grains, or agricultural waste, or it is also from ethylene (hydration). Currently, Ethanol can only be used primarily as a supplement to gasoline. The use of this energy can make for a much cleaner fuel than other fossil fuels (Seidel, Stephen, Dale Keyes 214-222 para3). There have been many different studies which have suggested that this corn-based ethanol will have a very negative energy balance. With this however, there’s a preponderance of some of these recent studies that have are using some updated data about corn production methods which demonstrates a positive energy balance for corn ethanol (Cothran 102-210 para 2)
When it comes to this pure ethanol, it is not a stand-alone fuel; well at least not yet. Ethanol commonly is now mixed with gasoline in varying percentages. Most of the pump gasoline has ethanol in lower percentages. Within the United States, they add this ethanol fuel into gasoline in varying quantities (mos...

... by volume than gasoline (Lim Yun Seng). With the whole demand of ethanol, it is particularly high in countries where the population is very high and therefore the amount of waste generated is large. Ethanol is just one of the sustainable energy resources that is intended to provide a more environmentally and economically friendly alternative to fossil fuels such as diesel and gasoline.
With the heating of the earth at such a very high rate, it is hard not to see the signs that the earth is polluting itself, and making the effects of global warming hard to hide. So cutting back on a high use of these fossil fuels like, coal, oil and other natural gases and turning to ethanol fuel we just might be able to slow down the damage being done to the earth now. Does ethanol solve our fuel problem in all aspects that are economically, environmentally, and its efficiency?

Ethanol as a Motor Vehicle Fuel Essay

- Ethanol as a Motor Vehicle Fuel Human society has been utilizing the limited inventory of fossil fuel for approximately 100 years. Due to its limited stock and availability a continuous search for alternative sources of fuel has proposed several alternatives to consider. Some of the alternative method includes rechargeable battery, fuel cell, alcohol based fuel, etc. There are two major types of alcohol that has been used as fuel. These are Methanol and Ethanol. Five to ten percent of methanol has been blended previously with the gasoline in the United States....   [tags: fossil fuel, south america, brazil]

Corn Ethanol: The Future Fuel? Essay

- In the world of global warming, all kinds of pollution and fuel shortages going on, renewable and clean/ green energy is increasingly the ideal solution of energy related problems we have to solve one way or another. Biofuel is one of the mainstream and highly supported solutions nowadays, an idea to make renewable fuel by living organisms such as fiber, corn, vegetable oil or sugar cane. Unlike nonrenewable fossil fuels over extracted by people causing various environmental problems like generating a considerable amount greenhouse gas, current technology already lets renewable fuel like biofuels to shrink a certain amount of greenhouse gas production, making it a more ‘clean’ source of ener...   [tags: global warming, renewable energy, brazil]

Essay on Ethanol: A Sustainable Fuel

- Sustainability refers to something that is used and can be replenished in time to use it again. The United States is known for being innovative and moving forward in its development. What keeps the United States mobile and moving. We use fuel, more specifically gasoline. The United states has become more aware of the environment and have found out that gasoline is a precious resource and is not unlimited. Many people fear changing fuel, because they have gotten used to gasoline. One way for the United States to become more sustainable is to fix its fuel source problem....   [tags: biofuel, gasoline, natural gas]

Essay Ethanol: Alternative Fuel

- Ethanol is an alcohol-based fuel made by fermenting and distilling starch crops, such as corn. It can also be made from “cellulosic biomass” such as trees and grasses. The use of ethanol can reduce our dependence upon foreign oil and reduce greenhouse gas emissions. As ethanol is available as E85, a high-level ethanol blend, as its a alternative fuel that can be used in flexible fuel vehicles that is a vehicle type that has an internal combustion engine and runs on either E85 or gasoline. With a 113 octane rating, ethanol is the highest performance fuel on the market and keeps today’s high-compression engines running smoothly....   [tags: Starch Crops, Waste Byproducts]

Ethanol Fuel Essay

- Missing Figures Ethanol Abstract: As of now we drive cars almost everywhere from home to the local store or different states. According to www.wikipedia.com there is “an estimated 243,023,485 registered passenger vehicles in the United States according to a 2004 DOT study!” 1That is a lot of cars. In a year the US alone consumes around 146 billion gallons of gasoline that is a huge amount. 2 According to figure 1 about 86% of all world energy comes from oil, gasoline, and coal; this leaves a tiny 14% to be divided among the other natural resources we could harness....   [tags: Energy Vehicle Automobile E85]

The unsuccesful use of ethanol Essay

- The Unsuccessful Use of Ethanol Current interest in ethanol fuel in the United States mainly lies in bio-ethanol, produced from corn, but there has been considerable debate about how useful bio-ethanol will be in replacing fossil fuels in vehicles. Concerns relate to the large amount of arable land required for crops, as well as the energy and pollution balance of the whole cycle of ethanol production. I don't think the US could implement the use of ethanol or other alternate fuels successfully as Brazil has done for many reasons: firstly, ethanol production in the United States does not benefit the nation's energy security, its agriculture, economy or the environment because ethanol produc...   [tags: Alternative fuel bio-ethanol]

Potential for Large Scale Ethanol Production Essay

- Potential for Large Scale Ethanol Production Recent legislation by the Congress of the United States has created a mandate for 5 billion gallons of renewable fuel (notably ethanol) to be consumed annually by 2015. In light of this recent push for alternative fuels, many different biomass solutions have been considered to meet the energy need for the 200 million cars on the road. While the most efficient bio-fuels are derived from palm oil and sugarcane, the Unites States has begun to focus on the more regional corn crops to produce new renewable fuels....   [tags: Renewable Fuel Ethanol Essays Papers]

The Advantages of Biobutanol Over Ethanol Essay

- Ethanol has recently come under fire for a variety of reasons. Ethanol uses more energy to be produced that it can yield, it drives up the cost of food crops, and it cannot be shipped efficiently (Hargreaves.) So what can be done about the problems with ethanol. Is there a better option for alternative fuel. Yes, biobutanol is the answer. Biobutanol is butanol that has been created by a biomass fermentation process that is similar to ethanol, but the resulting fuel has a few key advantages. Biobutanol is more feasible fuel source then ethanol, it can make use of existing infrastructure, and biobutanol has been proven to replace gasoline gallon for gallon....   [tags: Fuel, Gasoline, Alternative Fuel]
