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 production requires large fossil energy input to produce these fuels than you get out from the combustion of these products. Therefore, it is contributing to oil and natural gas imports and U.S. deficits. The country should instead focus its efforts on producing electrical energy from photovoltaic cells, wind power and burning biomass and producing fuel from hydrogen conversion.
Secondly, in Brazil reducing the rate of deforestation seemed likely to be more effective for taking carbon dioxide out of the atmosphere. In the United States, reliance on ethanol to fuel the automobile fleet would require enormous, unachievable areas of corn agriculture, and the environmental impacts would outweigh its benefits, destroying bio-diversity. Ethanol would be mainly made from bio organic material that will be especially grown for this purpose. It also uses a lot of fuel to grow these plants. The same goes for various kinds of vegetable oils that are said to be environmental friendly. Ethanol cannot alleviate the United States? dependence on petroleum, may, however, still be useful in regions or cities with critical pollution problems, and to make use of agricultural wastes. Basically, an increased demand for ethanol would cause land use changes - destroying forests and grasslands to grow corn or other ethanol crops - ethanol and other bio-fuels actually add to global warming.
Thirdly, as demand for ethanol fuel increases, food crops are replaced by fuel crops, driving food supply down and food prices up. Growing demand for ethanol in the United States has increased corn prices by 50% in Mexico. Average barley prices in the United States rose 17% from January to June 2007 to the highest in 11 years. Prices for all grain crops trend upward, reflecting a progressive increase in farm land devoted to corn for the production of produce ethanol fuel.

- Water, over half the planet is covered in this miraculous molecular compound. Water provides us with necessary hydration for our bodies, gives us means to grow crops and raise animals, it acts as a highway for boats and barges, and through water, humanity has thrived. The recipe for water is a relatively simple one, all you need is to combine one-part oxygen and two-part hydrogen and suddenly you have the key to life on earth. Water is arguably the most valuable resource that exists on planet earth and yet, it is quickly slipping out of our reach.... [tags: environmental issues, water-to-ethanol payoff]

- 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....

- Enzymes are like tools; you always get back what you started with after the reaction is complete. They speed up reactions by providing an alternative reaction pathway that requires lower activation energy. They are substrate specific. In order for an enzyme to work an enzyme and substrate must fit together like a lock and key. It has a region on its surface called the active site where the substrate binds. Once the substrate and enzyme have bounded, they form an enzyme-substrate complex. The enzyme-substrate complex reacts to form a product(s) and the resulting enzyme....

- ... When evolved in reactions, ethanol can produce different kinds of chemical compounds. Known as grain alcohol, ethanol is produced by crops, especially corn, since there is an abundant amount of corn in the United States. With this resource, the U.S. can become less dependent on foreign source of energy. Ethanol is also known as the most common biofuel. A biofuel is fuel made from renewable resources; in this case ethanol is made from the renewable resource of corn. Grain alcohol can be blended with gasoline and be used to power automobiles....

- 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.... [tags: Energy ]

- Since the invention of the internal combustion engine, car makers and consumers have been filling the gas tank with just that, gasoline. Starting out with leaded gasoline then slowly switching to unleaded gas in the late 1960s until catalytic converters, a new auto part which can only run on unleaded, were made mandatory in 1975. However over the past couple decades there have been a new contender in the fuel marketplace to power consumers’ cars. Ethanol is defined in World Book Student as “a type of alcohol found in alcoholic beverages and used as an automobile fuel” (Sheehan 1).... [tags: Energy ]

- 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....

Finally, the government spends more than $3 billion a year to subsidize ethanol production when it does not provide a net energy balance or gain, is not a renewable energy source or an economical fuel. Further, its production and use contribute to air, water and soil pollution and global warming, and the vast majority of the subsidies do not go to farmers but to large ethanol-producing corporations. Studies said that after taking into account expected worldwide land-use changes, corn-based ethanol, instead of reducing greenhouse gases by 20 percent, will increases it by 93 percent compared to using gasoline over a 30-year period. Biofuels from switch grass, if they replace croplands and other carbon-absorbing lands, would result in 50 percent more greenhouse gas emissions, the researchers concluded. Since ethanol is so corrosive, it cannot be piped to any location without causing the pipes to corrode very quickly, so therefore it must be trucked in, usually by diesel trucks, trains, or barges, which are more expensive and complicated than sending it down a pipeline. As refiners switched to ethanol this spring, the change in transport needs has likely contributed to the rise in gas prices. Some experts argue that the U. S. doesn't have adequate infrastructure for wide ethanol use. Also, ethanol contains less energy than gas. That means drivers have to make more frequent trips to the pump. Technologically, the process of producing ethanol from sugar is simpler than converting corn into ethanol, but the problem is that United States does not have enough corn fields. Converting corn into ethanol requires additional cooking and the application of enzymes, whereas the conversion of sugar requires only a yeast fermentation process. The energy requirement for converting sugar into ethanol is about half that for corn.
The United State desperately needs a liquid fuel replacement for oil in the near future," says Pimentel, a researcher of Environmental Economics & Sustainable Development, ?but producing ethanol or biodiesel from plant biomass is going down the wrong road, because you use more energy to produce these fuels than you get out from the combustion of these products."
