negative effects of ethanol in gasoline

Lead is still used in some aviation fuels. The EPA waiver authorizes, but does not require stations to offer E15. Additionally, Standard Oil was “reluctant … to encourage the manufacture and sale of a competitive fuel produced by an industry in no way related to petroleum.” The petroleum industry has controlled the fuels market ever since. The 200-page scientific roadmap cited recent advances in biotechnology that could aid use of cellulosic sources. One utility in São Paulo is buying more than 1% of its electricity from sugar mills, with a production capacity of 600 MW for self-use and 100 MW for sale. During these three decades the ethanol industry was awarded an estimated US$45 billion in subsidies and US$6 billion just in 2011. [25] As of June 2015[update], flex-fuel light-duty vehicle cumulative sales totaled 25.5 million units,[26] and production of flex motorcycles totaled 4 million in March 2015. The environmental effects of geothermal energy depend on how geothermal energy is used or how it is converted to useful energy. Found insideThey then consider the solutions the industry can adopt. The book reviews trends in more environmentally-friendly technologies such as the use of more sustainable fuel sources and new types of modular design with built-in recyclability. [103], Sucrose extracted from sugarcane accounts for little more than 30% of the chemical energy stored in the harvested parts of the mature plant; 35% is in the leaves and stem tips, which are left in the fields during harvest, and 35% are in the fibrous material (bagasse) left over from pressing. According to the Renewable Fuels Association the E15 waivers now cover 62% of vehicles on the road in the country. In the Midwest, ethanol was a more common component of RFG. Brazil is the world's second largest producer of ethanol fuel.Brazil and the United States have led the industrial production of ethanol fuel for several years, together accounting for 85 percent of the world's production in 2017. In March 2003 Volkswagen launched in the Brazilian market the Gol 1.6 Total Flex, the first commercial flexible fuel vehicle capable of running on any blend of gasoline and ethanol. The EPA also decided not to grant any waiver for E15 use in any motorcycles, heavy-duty vehicles, or non-road engines because current testing data does not support such a waiver. 1988: The Alternative Motor Fuels Act establishes incentives under CAFE for alternative fuel vehicles. It called for more open markets in biofuels and feedstocks to improve efficiency and lower costs. Ethanol produced using the biochemical process. The study found that higher oil prices and a weak dollar explain 25-30% of total price rise. [206] The use of ethanol-only vehicles has also reduced CO emissions drastically. In April 2008, Jean Ziegler, back then United Nations Special Rapporteur on the Right to Food, called biofuels a "crime against humanity",[228][229] a claim he had previously made in October 2007, when he called for a 5-year ban for the conversion of land for the production of biofuels. Following the lead phase-out in the United States, the oil refining industry chose to construct additional refining capacity to produce octane from other petroleum products, rather than from renewable sources such as ethanol. [91] As of 2008 researchers were attempting to breed new varieties adapted to U.S. soil and weather conditions, as well as to take advantage of cellulosic ethanol technologies to also convert sugarcane bagasse. This is because when you’re frequently refilling the gas tank with fuel, there’s less of a chance for water to … [19] Introduced in the market in 2003, flex vehicles became a commercial success,[20] dominating the passenger vehicle market with a 94% market share of all new cars and light vehicles sold in 2013. [123][124] As shown in the table, the United States remains the largest single importer of Brazilian ethanol exports, though collectively the European Union and the CBI countries now import a similar amount. A federal law was passed in October 1993 establishing a mandatory blend of 22% anhydrous ethanol (E22) in the entire country. [99][100][219], The impact assessment regarding future changes in land use, forest protection and risks on biodiversity conducted as part of the study commissioned by the Dutch government[104] concluded that "the direct impact of cane production on biodiversity is limited, because cane production replaces mainly pastures and/or food crop and sugar cane production takes place far from the major biomes in Brazil (Amazon Rain Forest, Cerrado, Atlantic Forest, Caatinga, Campos Sulinos and Pantanal)." It was not until the 1960s, following extensive health research, that the devastating health impacts of low-level lead exposure were established. The study also concluded that the neutralization of the carbon released due to land-use change was achieved in 1992. [65][66], In May 2011 the Open Fuel Standard Act (OFS) was introduced to Congress with bipartisan support. In terms of distribution, researchers calculates sugarcane ethanol's transport energy requirement to be .44 GJ per cubic-meter, thus one hectare of land would require 2.82 GJ of energy for successful transport and distribution. Final renewable fuel volumes for 2016 are 18.11 billion gallons, set at approximately 1 billion gallons higher than the 2013 proposal, and at just over 10 percent of the fuel supply. [95], During 2014 Brazil produced 23.4 billion liters (6.19 billion U.S. liquid gallons) of ethanol fuel, however, during that year Brazil imported ethanol from the United States, ranking as the second largest U.S. export market in 2014 after Canada, and representing about 13% of total American exports. [28][31] MTBE's use as an oxygenate additive was widespread due to mandates in the Clean Air Act amendments of 1992 to reduce carbon monoxide emissions. This open access book presents a comprehensive analysis of biofuel use strategies from an interdisciplinary perspective using sustainability science. Found insideThe book also considers other effects not quantified in dollar amounts, such as damages from climate change, effects of some air pollutants such as mercury, and risks to national security. [3] By December 2010 the U.S. ethanol production industry consisted of 204 plants operating in 29 states,[5][7] and 9 plants under construction or expansion, adding 560 million gallons of new capacity and bringing total U.S. installed capacity to 14.6 billion U.S. gallons (55.25 billion liters). CDM Potential in Brazil, by S. Meyers, J. Sathaye et al. As President Lula wrote for The Economist[184] regarding Brazil's global agenda: "Brazil’s ethanol and biodiesel programmes are a benchmark for alternative and renewable fuel sources. [citation needed], Fueling infrastructure has been a major restriction hampering E85 sales. Over 95 percent of gasoline sold in the United States is E10. The OECD study is also critical of the limited reduction of GHG emissions achieved from biofuels produced in Europe and North America, concluding that the current biofuel support policies would reduce greenhouse gas emissions from transport fuel by no more than 0.8% by 2015, while Brazilian ethanol from sugar cane reduces greenhouse gas emissions by at least 80% compared to fossil fuels. Brazil began exporting ethanol to the U.S. in 2004 and exported 188.8×10^6 US gal (715×10^3 m3) representing 44.3% of U.S. ethanol imports in 2007. [100], Until 2008, several full life cycle ("Well to Wheels" or WTW) studies had found that corn ethanol reduces greenhouse gas emissions as compared to gasoline. The negative about ethanol is that if you have investments in the oil industry, or you work for the oil industry, ethanol may impact your ability to make money. This plant was expected to go on line by 2010. [56] Registrations of flex-fuel cars and light trucks represented 87.0% of all passenger and light duty vehicles sold in the country in 2012. [146] The price ratio between gasoline and ethanol fuel has been well above 30 percent during this period for most states, except during low sugar cane supply between harvests and for states located far away from the ethanol production centers. This dissertation discusses the results from three different studies aimed at understanding the importance of fuel chemical structure during low temperature combustion (LTC) strategies, like homogeneous charge compression ignition (HCCI) ... [208] Sugarcane fields are traditionally burned just before harvest to avoid harm to the workers, by removing the sharp leaves and killing snakes and other harmful animals, and also to fertilize the fields with ash. The study found that higher oil prices and a weak dollar explain 25–30% of total price rise. The report also says that: "Rich countries spent up to $15 billion last year supporting biofuels while blocking cheaper Brazilian ethanol, which is far less damaging for global food security. In contrast, the report found that U.S. use of maize for biofuel is less efficient, as sugarcane can lead to emissions reductions of between 70% and well over 100% when substituted for gasoline. [99] Most future growth is expected to take place on abandoned pasture lands, as it has been the historical trend in São Paulo state. [54] In August 2012 the federal appeals court rejected the suit against the EPA ruling that the groups did not have legal standing to challenge EPA's decision to issue the waiver for E15. Found insideThe book shows also some aspects of the environmental impact of the production and biofuels using, and describes perspectives of biofuel production technology development. [citation needed], Once harvested, sugarcane is usually transported to the plant by semi-trailer trucks. Motorists drove less, gasoline prices dropped sharply, capacity rose and less financing was available. "[216] The analysis also showed that intensification of cattle ranching, combined with efforts to promote high-yielding oil crops are required to achieve effective carbon savings from biofuels in Brazil, "while still fulfilling all food and bioenergy demands. A key argument of E30 proponents is that higher-ethanol blends would reduce the need for alternative fuel additives that may have negative health effects. STA-BIL 360 Protection, America's #1 Ethanol Treatment, is engineered to combat the negative effects of ethanol-blended fuels. During the same period, the share of temporary or seasonal workers has fluctuated, first declining and then increasing in recent years to about one-half of the total jobs in the sector, but in absolute terms the number of temporary workers has declined also. Found insideThe book focuses on fuel consumption-the amount of fuel consumed in a given driving distance-because energy savings are directly related to the amount of fuel used. [104] Even though sufficiently strict labor laws are present in Brazil, enforcement is weak. [73] By December 2010 both Honda flexible-fuel motorcycles had reached cumulative sales of 515,726 units, representing an 18.1% market share of the Brazilian new motorcycle sales in 2010. [92][93], U.S. sugarcane production occurs in Florida, Louisiana, Hawaii, and Texas. [14][15] Since then, the government has set the percentage of the ethanol blend according to the results of the sugarcane harvest and the levels of ethanol production from sugarcane, resulting in blend variations even within the same year. [213] Mechanization will reduce pollution from burning fields and has higher productivity than people, but also will create unemployment for these seasonal workers, many of them coming from the poorest regions of Brazil. [46][47][48] By 2010 manufacturers that build flexible fuel vehicles include Chevrolet, Fiat, Ford, Peugeot, Renault, Volkswagen, Honda, Mitsubishi, Toyota, Citroën, Nissan, and Kia Motors. Today, there are two primary sources of octane used in the U.S. gasoline supply, the BTEX complex (a petroleum refining product commonly referred to as gasoline aromatics), and ethanol. 1992: The Energy Policy Act of 1992 defines alternative fuels and establishes programs at the federal level to increase the use and research of alternative fuels. In a similar way, and without considering potential indirect land use effects, the costs to taxpayers of reducing greenhouse gas emissions through tax credits were about $750 per metric ton of CO2-equivalent for ethanol and around $275 per metric ton for cellulosic ethanol. [105] This hydrous ethanol is the fuel used by ethanol-only and flex vehicles in the country. Since 1976 the government made it mandatory to blend anhydrous ethanol with gasoline, fluctuating between 10% to 22%. Automotive manufacturers are examining clean octane sources as a way to meet efficiency and greenhouse gas regulations. [179] Brazil also has bilateral cooperation agreements with several other countries in Europe and Asia.[183]. [104], Some environmentalists, such as George Monbiot, have expressed fears that the marketplace will convert crops to fuel for the rich, while the poor starve and biofuels cause environmental problems. [63][64] This preliminary report found that none of the vehicles displayed a malfunction indicator light; no fuel filter plugging symptoms were observed; no cold start problems were observed at 24 °C (75 °F) and 10 °C (50 °F) under laboratory conditions; and all test vehicles exhibited a loss in fuel economy proportional to ethanol's lower energy density. Found inside – Page 305The substitution effect is highly significant and reduces the gasoline price ... The West Coast and East Coast experience similar negative ethanol impacts ... The average number workers with 3 or less school years in Brazil is 58.8%, while in the Southeast this percentage is 46.2%, in the Northeast region is 76,4%. [85], Ethanol production is concentrated in the Central and Southeast regions of the country, led by São Paulo state, with around 60% of the country's total ethanol production, followed by Paraná (8%), Minas Gerais (8%) and Goiás (5%). The fuel is sold through a blender pump that allows customers to choose between E10, E15, E30 or E85, with the latter blends sold only to flexible-fuel vehicles. [85][104] The typical steps for large-scale production of sugar and ethanol include milling, electricity generation, fermentation, distillation of ethanol, and dehydration. In recent years however, later-generation biofuels have sprung up which don't use food crops that are explicitly grown for fuel production. [72], One rationale for ethanol production in the U.S. is increased energy security, from shifting supply from oil imports to domestic sources. [46][47] As of 2008, GM badged its vehicles with the text "Flexfuel/E85 Ethanol". The chemical compound ethanol, also known as ethyl alcohol or grain alcohol, is the bio-alcohol found in alcoholic beverages.When non-chemists refer to "alcohol", they almost always mean ethanol.It is also increasingly being used as a fuel (usually replacing or complementing gasoline). "[173], A July 2008 OECD economic assessment[174] agreed about the negative effects of subsidies and trade restrictions, but found that the impact of biofuels on food prices was much smaller. Today, the majority of ethanol in the United States is blended with gasoline to produce E10 (10 percent ethanol, 90 percent gasoline). By early 2013, about 11 million E85 flex-fuel cars and light trucks were in operation,[8][9] though actual use of E85 fuel was limited, because the ethanol fueling infrastructure was limited. The California plant was expected to produce 60×10^6 US gal (230×10^3 m3) a year and it was expected in 2011. Found insideThis section helps you understand the negative effects ethanol fuel can have and what you can do to defend your boat engine against them. [67][68][69], In November 2013, the Environmental Protection Agency opened for public comment its proposal to reduce the amount of ethanol required in the US gasoline supply as mandated by the Energy Independence and Security Act of 2007. [94] As a result of higher ethanol prices combined with government subsidies to keep gasoline price lower than the international market value, by November 2013 only 23% flex-fuel car owners were using ethanol regularly, down from 66% in 2009. STA-BIL 360 Protection is the ultimate ethanol treatment. The addition of ethanol blends instead of lead to gasoline lowered the total carbon monoxide (CO), hydrocarbons, sulfur emissions, and particulate matter significantly. [104][185], However, two studies published in 2008[159][164] are critical of previous assessments of greenhouse gas emissions reduction, as the authors considered that previous studies did not take into account the effect of land use changes.
