The harmful effects of biofuels
Biofuels: Mandating Harmful Consequences Energy is the common currency of all living things; something all species need. While plants rely directly on the sun for energy, humans rely on an array of sources like wind, fossil-fuel, water, solar, and more recently biofuels. Of these biofuels, which are fuels obtained directly from living plant matter, ethanol and biodiesel are the most commonly used. These two sources are typically used to fuel cars, trucks, aircraft, and small-engine machines. Biofuels have garnered much attention because they are derived from renewable resources like corn and soybeans rather than non-renewable fossil fuels. The main advantage to biofuels has always been that they give off fewer green-house gasses (GHG), particularly carbon,that petroleum-based fuels are notorious for emitting. Analyzing biofuels from an environmental prospective, they seem to be a positive alternative to replacing society’s addiction to fossil-fuels. However, the amount of fuel need to produce these crops and the amount of cropland needed to supply a nation with biofuel is often ignored in the comparison. Besides requiring high input of energy, space, fertilizer, and pesticides, switching our economy to a biofuel reliant one will lead to deforestation—additional emission of GHGs—and higher priced food. For these reason, among others, the production of biofuels is harmful to consumers, producers, and the environment. Past studies have concluded that replacing traditional gasoline with biofuels, such as ethanol and biodiesel, would cause a reduction in the amount of greenhouse gasses emitted into the air. This aspect is especially important to humanity because many climate and ecosystem experts preach that dangerous climate change is bound to happen when our atmosphere is over 350 ppm (parts per million) carbon. We are currently at 397 ppm. Biofuels appear to be better than petroleum-based fuels because the idea was that the additional plants that would be

    Fossil fuels are currently the most widely used source of nonrenewable energy in today’s society. These sources of energy are used to generate power for both commercial and personal use in a number of different ways. “In 2005, more than 3/4 of total world energy consumption was through the use of fossil fuels.” (Environmental Literacy Council, 2008) Oil, the leading energy resource depended upon to fuel everyday functions produces 43.4 % of our world’s energy. Natural Gas, the second most relied upon resource produces 15.6 % of the world’s energy followed by coal, which produces 8.3 % of the world’s energy. Unsurprisingly, North America is the number one consumer of nonrenewable energy resources, consuming approximately 25 % of the fossil fuels extracted from the earth.

    Throughout the past few decades sources of renewable energy have been widely discussed due to the harmful impacts fossil fuels have on the environment combined with fluctuating petroleum prices and our growing demand for an ever depleting resource (Fletcher et al. 2011). Over the coming decades it is predicted that there will be an increase in the use of bioenergy systems (McBride et al. 2011). Bioenergy is commonly believed by both policy makers and environmentalists to be one of the…

    Why do we do this? Because our policy makers have come to believe that the air-born plant food carbon dioxide is a “pollutant” (3) that must be reduced or severe damage will be done to the biosphere. Acting on this belief the US government is planning on turning enough food into fuel by 2022 that could feed half the population of the United States! Even if carbon dioxide were a “pollutant” the use of biofuels produces little or no net reduction in carbon emissions since by some estimates it takes more energy to produce a gallon of ethanol than what one gets back from it when it is burned. "Adding up the energy costs of corn production and its conversion to ethanol, 131,000 BTUs are needed to make 1 gallon of ethanol. One gallon of ethanol has an energy value of only 77,000 BTU." (4)…

    Years ago farmers were encouraged to grow more and were given government grants to do so. “Most of this comes from the Bush administration wanting to have ethanol to replace twelve percent of oil consumption by 2014” (Collapse movie). This would take all of the arable land and therefore this did not work for the simple fact that net energy would not allow it to be a viable fuel source. So now if one where to go to Iowa or Nebraska all they would see for miles and miles are would fields of corn. In 1979 a comity was formed to see just how efficient ethanol really was David Pimentel, professor emeritus of entomology at Cornell University concluded from this study that it would take more energy to produce ethanol than one could get out of it.”Department of Energy invited Pimentel to chair an advisory committee to look at ethanol as a gasoline…

    According to America's energy department, ethanol results in fewer greenhouse gas and carbon emissions compared to unleaded gasoline, and is fully biodegradable (Biofuels). The national average reduction in emissions for corn ethanol is roughly twenty percent. The reason emissions fluctuate is because not every batch of e85 is eighty-five percent ethanol. The maximum number of reduction from pump e85 is fifty-two percent. In addition, ethanol produced from corn cellulose can have numbers very close to a seventy-eight percent reduction. Additionally in the future, ethanol made from biomass cellulose can reduce emissions by eighty-six percent compared to gasoline. Furthermore, according to the Alternative Fuel Data Center, e85 decreases emissions of carbon dioxide, carbon monoxide, and other harmful toxics (Ethanol). The United States is the second greatest carbon polluter right after China. With cars running on e85 carbon emissions in the United States can reduce drastically. Brazil, a country in which relies heavily on the use of ethanol fuel, produces roughly one-tenth the amount of carbon emissions that the United States does. Many people believe that milling ethanol is more harmful to the environment than drilling for gasoline. However, ethanol is made from things that are grown, ethanol’s waste can be recycled into food for livestock, and many other countries have been using it with positive results. On the other hand, gasoline is being produced by big machines which drill oil from the bottom of the ocean. Using ethanol-based fuels rather than petroleum fuels doesn't only reduce the amount of carbon toxins, greenhouse gasses, and is made from natural resources, but it also can help save consumers money at the…

    This renewable source of energy has acted as an advantage over the past years by providing an alternative to foreign oil. However, this renewable energy resource has also created numerous drawbacks including an extensive amount of environmental damage as well as an inflation in the food market costs (Brush, 2014). This extensive amount of damage has caused the Obama Administration to propose the reduction of ethanol usage. This proposal has caused a sudden outrage by farmers who make a living off of corn-based ethanol (Brush, 2014). Many are concerned that this sudden proposition could be a tremendous drawback in the alternative energy industry. However, with current technological advances the world of ethanol could significantly change and impact in the near future.…

    Although ethanol has provided our world with many benefits, there are also many drawbacks as well. Because ethanol is manufactured from corn crops, the value of most corn is higher in costs. This drawback plays a role not only in the world of energy but also in the food industry, thus overall impacting our economy. In addition, the corn also requires a large quantity of land in order to produce enough material for the ethanol. Farm land is very scarce and difficult to come by, because of the constant increase in population. However, the need for land involves more drawbacks within itself. The act of farming includes the possibility of harming the environment in ways such as: fertilizer, pesticides, soil erosion, salinity, or deforestation.…

    Ethanol Green Myth

    In actuality it takes one-point-seven times more energy to produce and process the corn for ethanol, and then have to distill it than we save from actually using it as a fuel for our vehicles (Potera A18). It is also a myth that we as a country will somehow or someday ever be one-hundred percent free from foreign oil use or importation. Professor David Pimentel of Cornell University in Ithaca, New York states that "The myth is that ethanol frees us from dependence on oil, yet we actually import oil to run ethanol plants and grow the corn," (qtd. in Potera A18). Ethanol may initially be cheaper when you are filling your vehicle up at the gas-pump, about thirty-cents less per gallon, but when you factor in ethanol blended fuels poorer gas-mileage, the overall cost is slightly higher for most drivers (Newman 2012). It is also more harmful for car engines then regular non-ethanol fuels are, reducing the engines longevity and hitting our pocket books when it comes to repairs. Scott Faber, the Vice President of Government Affairs for The Environmental Working Group (EWG) whose mission is to “empower people to live healthier lives in a healthier environment.” stated is a 2013 press release that "Ethanol is more corrosive and burns hotter than gasoline, properties that could cause some engines to stall, misfire and overheat.” He further stated that fuel with higher ethanol blends emits more pollutants like nitrous oxide and formaldehyde than gasoline does, and it also lowers gas-mileage and damages the vehicles fuel tanks and pumps (Faber 2013). Not only is ethanol not as green as once thought, lowers gas mileage, and is harmful for engines, it is also taking a toll on food prices and availability around the…

    Ethanol has been sold to the American people by politicians as a reliable, relatively clean, sustainable source of energy to replace gasoline. This seems to be far from the truth. Even if all of America’s corn was used for food production it would still only help to replace 6% of the total amount of oil consumed by the U.S. The grain required to fill just one 25-gallon gas tank would feed a person for an entire year.…

    Energy is the foundation of industrialized world; without energy, life as we know it would cease to exist. The yearly energy and fuel consumption rates have risen dramatically within the last years. This phenomenon is a direct result of globalization pressures, the international information network we call the Internet, and a population that seems to be hitting the dangerous upswing of the Malthusian curve. Although there is not yet a current shortage of conventional fuels, such as reserves of coal, oil and other fossil fuels are limited and non-renewable. In addition, the common practice of burning oil, coal, and other assorted hydrocarbons has resulted in hazardous environmental conditions such as global warming, acid rain and dangerously high air pollution levels. This and other environmental disasters have brought about a demand for alternative fuel and energy sources that are convenient, environmentally friendly, and economically viable. The U.S. Department of Energy defines alternative fuel as fuel that is essentially non-petroleum and yields energy security and environmental benefits. Following are some of the fuels the Department of Energy currently recognizes as alternative fuels methanol, hydrogen, liquid and compressed natural gas, and electric fuel. Alternative sources of energy are classified as energy provided from sources other than fossil fuels. This includes but is not limited to nuclear power, solar power, hydropower and biomass. Currently, many of these alternate sources are in use, but unfortunately they are underused or underdeveloped because of perceived shortcomings or drawbacks. While some of these fuel and energy sources may indeed lack the efficiency or cost effectiveness of the conventional fuel and energy, having a clean living planet far outweighs the cost of clean energy.…
