Environmental Science - Research Paper ExampleAccording to all peer-reviewed scientific studies, if the quantity of greenhouse gasses being spewed into the pipeline by automobiles, power plants and factories is not greatly put downd and quickly, the earth and its inhabitants lead experience catastrophic consequences in the not too distant future. This paper leave discuss the viability of various alternative fuels such as hydrogen, bio- fuels, solar, geothermal and nuclear sources which if put into practice on a wide scale would significantly reduce air pollution and perhaps circumvent the predicted effects. One solution to reducing automobile emissions may be found in vegetable fields. The conversion of give or beets into ethanol is promoted by scientists as an environmentally and economically sound solution to global climate change concerns. However, this is hardly a new revelation. Rudolf Diesel, in 1897, fifteen years after the inventing the engine named after him said The u se of vegetable oils for engine fuels may seem insignificant today. But such oils may become, in the course of time, as aftermathant as petroleum and the coal products of the present time (Boles, 2005). ... Bio-fuels are derived from a readily accessible source and blow over no pollutants. The most familiar kind, Ethanol, is a vegetable oil which is most often be mixed with gasoline and bio-diesel. It can be burned by diesel engines without altering the engine. Ethanol, a green fuel, could be used as a bridge to the future of consumption and slide fastener fruit because it can be used in existing engines unlike hydrogen. Another by-product of the bio-fuels industry is tit will fuel the growth of agricultural businesses. Regrettably, it takes significantly more energy (from high-grade gasoline) to create ethanol than it build ups. It takes approximately70 percent more energy to produce a gallon of ethanol than is contained in a gallon of ethanol. In addition, fossil fuel is use d in the production of corn or any crop used for ethanol and by increasing ethanol production will increase degradation of vital agricultural and water resources and will seriously contribute to the pollution of the environment (Pimentel, 1998, p. 5). European countrys both produce and consume close to 90 percent of the worlds bio-fuel. Brazil makes up most of the remaining 10 percent. Brazil produces more bio-fuel than it consumes and does not import crude oil. The South American nation is energy independent and among the lowest producers, by capita, of greenhouse gasses. The quantity of bio-fuels produced and consumed is predicted to grow significantly over the next decade. It is come-at-able that (bio-fuels) could represent as much as 20 percent of all on-road diesel used in Brazil, Europe, China and India by the year 2020 (Biodiesel, 2006). In the U.S., the production of bio-fuels grew six-times during a two year period
