Biofuels Essay

Biodiesel fuel has many advantages over diesel fuel that allows it to be a better fuel than diesel fuel such as improving the environment, decrease the U.S. dependency on foreign petroleum, and reducing the amount of hurtful contaminants. On the other hand, occasionally people think that biodiesel has more disadvantages than advantages. For example, biodiesel is “currently more expensive” than petroleum based fuels, and biodiesel is “not suitable for use in low temperatures” (“Biodiesel”). People also perceive biodiesel as a disadvantage since, there is a “concern of biodiesel’s influence on engine durability” (“Biodiesel”). In spite of, some people thinking that biodiesel have further disadvantages than advantages others respectably disagree.

How can alternative sources of energy be harnessed effectively? Biogas has been found to be a sustainable source of energy which is creates less emissions compared to coal and oil (1). Due to everyday needs and wants of the growing populations of the world, natural resources have been used and over used to a point where they are no more as available, such as fossil fuels in Kristianstad(2). This unfortunately creates concern for the future however, an alternative source of energy has been found and is being implemented in the Swedish city so that the strain on the over use of natural resources can be relieved(3). Biogas is produced from biomass and it is the best sustainable plan as a source of energy and a way to be more environmentally conscious(4).

Whereas fossil fuels are limited since they come from specific materials years ago, biofuels are renewable (since you can always produce more if it runs out) and can be manufactured from a variety of materials such as: crop waste, manure and other byproducts. This takes recycling to a new constructive level. Likewise, the amount of carbon emissions will also decrease drastically since when biofuels are used, they produce significantly less carbon and fewer toxins. This also makes them a safer alternative in order to preserve atmospheric quality and lower air pollution. In terms of economic stimulation, the economy will find stability as when using biofuels you can disregard afore mentioned fluctuating oil prices due to change in demand.

Even when using a conventional fuel options, weight reduction is an important factor to the improvement of fuel efficiency. “The demand for weight reduction in automotive vehicles has been increasing in recent years because of global environmental issues.” (Saito, Iwatsuki, Yasunaga, & Ando, 2000, p. 515) Various types... ... middle of paper ... ... on foreign oil. As of now hybrids do not have the popularity in the world that is needed. If the world continues to pollute at the rate it is going at now, the implications will be serious. More effort is needed from everyone to make this world a better place, and while hybrid vehicles are going to be extremely important, that is not the only thing that can be done.

Despite the minor setbacks of biofuels in the beginning, with some time and dedication biofuels will be worth converting over to from oil. Converting over to biofuels will eventually change life as Americans know it. It will transform society into a much more energy efficient, green, and healthy place to grow as humans. Unfortunately, many people argue that converting from oils over to biofuels is a waste of time, and will later have no effect on the planet. However, research shows that if the people in general society start working together and changing the way they live their lives one by one, those individuals will eventually create a positive change for the world.

6). Most cars and trucks on the road today are powered by gasoline or diesel engines, which are expensive to operate, bad for the environment, and use resources that are non renewable. To achieve better fuel economy, lower operation cost, reduce the pollution on the environment, and operate vehicles with renewable resources, this world needs to take a better look at using alternative fuels to power vehicles. Alternative fuels for motor vehicles are better for the environment, are renewable resource, and are cheaper for consumers. The first reason alternative fuels should be used is to better the environment.

Aside from the dependence on foreign nations, bio-fuels pose environmental advantages to producers and consumers. They are a relatively clean burning source of energy unlike oil, which accounts for more than 32 percent of... ... middle of paper ... ...ncreasing day by day7. The third factor, relating and supporting industries explains that when local industries compete against one another, this spurs the emergence of cost effective and innovative inputs. This very well indicates that in the future biofuel demand will lead to more innovative, cheaper production. The last factor, firm strategy, structure, and rivalry states that over the long run more local rivalry is better since it puts pressure on firms to innovate and improve.

More farmers are now planting crops for biofuel, resulting to an intense drop in food production. According to experts this promising alternative energy source is seemingly causing a global decrease of food supply. As the demand for biofuels increases, more industrialized countries are offering encouragements and subsidizing farmers to grow crops for fuel rather than for food. The biofuel production method was also anticipated to be carbon neutral, as the crops would absorb the carbon dioxide released when the biofuel was burned. However crops for fuel are now grown at such a rate that they need more energy to cultivate, grow and harvest.

Its main advantages over fossil fuels are that bio fuels are better for the environment and can be produced right here in the United States. Although some experts complain that bio fuels release carbon dioxide into the atmosphere, which is a greenhouse gas that causes global warming, they are actually carbon dioxide neutral. This is because the growing of the plants used in biomass production take in as much carbon dioxide as the bio fuels let out. Some experts as well as lobbyist for the farming industry are pushing ethanol from corn as the replacement for gasoline. While we believe every alternative to gasoline should be explored, using corn to produce ethanol is not a good idea.

 Secondly, whereas oil is a limited resource that comes from specific materials, biofuels can be manufactured from a wide range of materials including crop waste, manure, and other byproducts. This makes it an efficient step in recycling.  Thirdly, it takes a long time for fossil fuels to be produced, but biofuels can be easily renewable as new crops are grown and waste material is collected.  Fourthly, biofuels can be produced locally, which decreases the nation's dependence upon foreign energy. By reducing dependence on foreign fuel sources, countries can protect the integrity of their energy resources and make them safe from outside
