Green Cars绿色环保车
代写留学生论文环境问题,特别是如果我们谈论全球变暖,所造成的石油和天然气的使用在运输领域和行业,生长于每年。总之,这些问题让世界充满活力的危机。在过去的100年里,人们已经制造出大量的二氧化碳,甲烷的氧化亚氮,并且由于它平均气温转暖了超过半度。燃烧化石燃料,如石油、煤与瓦斯突出的影响我们的大气层,并负责全球变暖方面20th世纪。谎言气温已成为当今更暖和,因为热不能回到太空。额外的温室气体增加的温室效应。使用石油运输产业造成严重损害环境与这个问题不容忽视。
Gasoline-burning汽车是全球变暖的来源的污染。这一步解决这个问题的办法是使用混合型、新技术和所谓的“绿色”汽车。“到2050年,燃料电池技术可以提高效率和其他进步到54英里每加仑”(Koffer,2005)。政府可以做它的帮助efficient-energy技术和可再生能源,它可以是一个步骤来解决温室效应和精力充沛的危机问题。它也是更好地照顾你的汽车,因为well-tuned车汽油消耗量低于少的二氧化碳,所以生产。
大多数现代运输系统是基于石油。统计显示,三分之二的美国石油用于用于功率运输。“目前,运输燃料的大约占全世界半数的石油消耗量。运输的份额上升到60%,如果我们包括沥青道路沥青,随着润滑剂和炼油厂生产中使用的能源的柴油和汽油。石油使用在运输领域,从而保持一个司机的总全球石油需求”(芒迪,3)。运输部门的增长会自然地导致能源日益增长的需要为运输车辆。什么是值得注意的,尽管有极其重要的作用,它的能量对经济、能源价格上涨不会导致大石油和天然气的供应。只要生产石油的供给将会达到峰值逐渐减少一半,油价将会成长。这肯定会有负面影响,运输领域,特别是在世界经济中一般。解决这些问题的办法之一可以使用“绿色”的汽车。这将会导致现有引擎的进步切换汽油柴油,使用混合动力汽车、燃料电池车、技术,减少燃油效率的不足。
所谓的“绿色”汽车不能独自解决全球变暖问题和充满活力的危机。解决全球问题需要联合运行的国家的政府、公司和所有的人。这是基本不可能的减少全球温室污染的政府参与积极、主动。当然,它是不可能成功没有政府的帮助和支持。全球变暖问题,所以在所有人触及1997年12月,联合国通过了《京都议定书》,旨在加强国际社会应对全球变暖,气候变化。
然而,使用“绿色”的汽车可以减少汽油的消费,进而可以帮助阻止精力充沛的危机。它只能在这个问题的第一步解决方案和进一步协调力和有效措施将带来成功。
Environmental problems, especially if we speak about global warming, which are caused by the use of gas and oil in transport sector and industry, grow with each year. All in all, these problems let to the world energetic crisis. During the last 100 years people have produced a lot of carbon dioxide, methane and nitrous oxide and as a result of it the average temperature has warmed up by over half a degree. Burning fossil fuels, such as oil, coal and gas influences our atmosphere and so the responsibility for the global warming in the 20th century lies on people. Nowadays the air temperature has become much warmer because the heat cannot go back into space. Extra greenhouse gases increase the greenhouse effect. The use of oil in transport industry causes serious damage to the environment and this problem cannot be neglected any more.
Gasoline-burning cars are one of the source of the global warming pollution. The step towards the solution of this problem is the usage of hybrid engines and new technologies and the so-called “green” cars. “By 2050, fuel-cell technologies and other advancements could boost efficiency to 54 miles per gallon” (Koffer, 2005). The government can do it with the help of renewable energy and efficient-energy technologies and it can be one of steps towards the solution of the greenhouse effect and energetic crisis problem. It is also better to take care of your car, because a well-tuned car consumes less gasoline and so produces less carbon dioxide.
Most modern transport systems are based on oil. Statistics show that two thirds of all petroleum used in the US is used for power transportation. “At present, transportation fuels account for roughly half of the world’s oil consumption. Transportation’s share increases to 60% if we include bitumen for road asphalt, along with lubricants and the energy used in refinery production of diesel and gasoline. Oil use in the transport sector will thus remain a driver of total global oil demand” (Mandil, 3). The growth of transport sector will naturally lead to the growing needs in energy for transport vehicles. What is notable, despite extremely important role, which energy plays for economy, the rise of prices for energy will not result in bigger supplies of gas and oil. As soon as the production of oil reaches its half-way peak supplies will gradually decrease while the prices for oil will grow. This will definitely have negative effect on transport sector in particular and on the world economy in general. One of the ways out can be the usage of “green” cars. It will lead to the improvements in existing engines switching from gasoline to diesel, use of hybrid vehicles, fuel cell vehicles, technologies that reduce the fuel efficiency shortfall.
留学生论文代写The so-called “green” cars alone will not resolve the problem of global warming and energetic crisis. The solution of the global problem requires joint operation of the government of the country, companies and all people. It is practically impossible to cut global warming pollution without active governmental participation. Of course, it is impossible to reach success without governmental help and support. The problem of global warming touches all people and so in December 1997, the United Nations passed the Kyoto Protocol, which aimed to strengthen the international response to the global warming and climate changes.
However, the usage of “green” cars can reduce the consumption of gasoline which, in its turn, can help to stop energetic crisis. It can be only the first step in this problem solution and further coordinated forces and effective measures will bring success.
