文献出处:Moriarty P, Honnery D. The prospects for global green car mobility[J]. Journal of Cleaner Production, 2008, 16(16): 1717-1726.原文The prospects for global green car mobilityPatrick Moriarty, Damon HonneryAbstractThe quest for green car mobility faces two major challenges: air pollution from exhaust emissions and global climate change from greenhouse gas emissions. Vehicle air pollution emissions are being successfully tackled in many countries by technical solutions such as low-sulphur fuels, unleaded petrol and three-way catalytic converters. Many researchers advocate a similar approach for overcoming transport's climate change impacts. This study argues that finding a technical solution for this problem is not possible. Instead, the world will have to move to an alternative surface transport system involving far lower levels of motorised travel.Keywords:Green mobility; Fuel efficiency; Alternative fuels; Global climate change; air pollution1. IntroductionProvision of environmentally sustainable (or green) private transport throughout the world faces two main challenges. The first is urban and even regional air pollution, particularly in the rapidly growing cities of the industrialising world. The second is global climate change, caused mainly by rising concentrations of greenhouse gases (GHGs) in the atmosphere. These two barriers to green car mobility differ in several important ways. First, road traffic air pollution problems are more localised, because of the short atmospheric lifetimes of most vehicle pollutants and . Thus regional solutions are often not only possible, but also essential – Australian cities, for example, can (and must) solve their air pollution problems themselves. Matters are very different for global climate change. Except possibly for geo-engineering measuressuch as placing large quantities of sulphate aerosols in the lower stratosphere or erecting huge reflecting mirrors in space, one country cannot solve this problem alone. Climate change is a global problem. Nevertheless, it is possible for some countries to ‘freeload’ if the majority of nations that are important GHG emitter。

发展电动汽车英语作文

发展电动汽车英语作文The development of electric cars has been gaining momentum in recent years, as the need for a more sustainable and environmentally friendly mode of transportation becomes increasingly urgent. With the growing concerns over climate change and air pollution, electric cars have emerged as a promising solution to reduce carbon emissions and improve air quality.Electric cars, also known as EVs, are powered by electricity instead of gasoline or diesel fuel. They use rechargeable batteries to store energy, which powers an electric motor to drive the vehicle. Unlike traditional cars, electric cars do not emit harmful pollutants such as carbon dioxide, nitrogen oxide, and particulate matter. This makes them a cleaner and greener alternative to gasoline-powered vehicles.One of the main advantages of electric cars is their lower operating cost. EVs are much more efficient than gasoline-powered vehicles, as they convert up to 80% of the energy stored in the battery to power the wheels, compared to only 20% for internal combustion engines. This meansthat electric cars require less energy to travel the same distance, resulting in lower fuel costs. Moreover, electric cars have fewer moving parts than gasoline-powered cars, which reduces the need for maintenance and repair, and prolongs their lifespan.Another advantage of electric cars is their quiet and smooth operation. Unlike traditional cars, electric cars do not have a noisy engine, which makes them much quieter and more comfortable to drive. Electric cars also have instant torque, which means that they can accelerate quickly and smoothly, without the need for shifting gears. This makes them a pleasure to drive, especially in stop-and-go traffic.Despite their many advantages, electric cars still face some challenges that need to be addressed to acceleratetheir adoption. One of the main challenges is their limited driving range and long charging time. Most electric carscan travel around 100-300 miles on a single charge, whichis much less than the range of gasoline-powered cars. Moreover, recharging an electric car can take several hours, depending on the charging speed and the battery capacity. This can be inconvenient for drivers who need to travellong distances or who do not have access to a charging station.To overcome these challenges, several initiatives have been launched to promote the development and adoption of electric cars. Governments around the world have introduced incentives and subsidies to encourage consumers to buy electric cars, such as tax credits, rebates, and free parking and charging. Car manufacturers have also invested heavily in research and development to improve the performance and affordability of electric cars, and to develop new charging technologies that can reduce the charging time and increase the driving range.In addition, the infrastructure for electric cars is also expanding rapidly, with more charging stations being installed in public places such as malls, hotels, and parking lots. This makes it easier for electric car owners to recharge their vehicles on the go, and to travel longer distances without worrying about running out of power. Furthermore, advances in battery technology are also expected to improve the driving range and reduce the charging time of electric cars in the near future.In conclusion, the development of electric cars is a promising trend that offers many benefits for the environment, the economy, and the consumers. Electric cars are cleaner, cheaper, and more enjoyable to drive than gasoline-powered cars, and they have the potential to transform the way we travel and live. With the support of governments, car manufacturers, and consumers, electric cars are poised to become the mainstream mode of transportation in the coming years, and to contribute to a more sustainable and prosperous world.。

电动车:正在进行的绿色交通革命?随着世界上持续的能源危机,战争和石油消费以及汽车数量的增加,能源日益减少,有一天它会消失得无影无踪。
石油并不是可再生资源。
在石油消耗枯竭之前必须找到一种能源与之替代。
随着科技的发展和社会进步,电动车的发明将会有效的缓解这一燃眉之急。
电动汽车将成为理想的交通工具。
面临能源成本居高不下、消费者和政府更加重视环境保护的情况下,世界汽车制造商正加大对可替代能源性混合动力汽车技术的开发投资。
该技术能极大削减燃料消费,减少温室气体排放。
许多人把目光投向了日本和美国的汽车制造商,关心他们开发混合动力和电池电动车的进展情况。
丰田普锐斯一跃成为世界上销量最好的混合动力车。
美国的新兴汽车制造商,Tesla Motors,推出了该公司首部电池电力车,名为Tesla Roadster。
截至2010年底,通用汽车公司计划推出备受赞誉的V olt混合动力汽车,而克莱斯勒公司最近已经宣布同样的计划正在进行之中。
目前,中国在新能源汽车的自主创新过程中,坚持了政府支持,以核心技术、关键部件和系统集成为重点的原则,确立了以混合电动汽车、纯电动汽车、燃料电池汽车为“三纵”,以整车控制系统、电机驱动系统、动力蓄电池/燃料电池为“三横”的研发布局,通过产学研紧密合作,中国混合动力汽车的自主创新取得了重大进展。
形成了具有完全自主知识产权的动力系统技术平台,建立了混合动力汽车技术开发体系。
混合动力汽车的核心是电池(包括电池管理系统)技术。
除此之外,还包括发动机技术、电机控制技术、整车控制技术等,发动机和电机之间动力的转换和衔接也是重点。
从目前情况来看,中国已经建立起了混合动力汽车动力系统技术平台和产学研合作研发体系,取得了一系列突破性成果,为整车开发奠定了坚实的基础。
截止到2009年1月31日,在混合动力车辆技术领域,中国知识产权局受理并公开的中国专利申请为1116件。
在1116件专利申请中,发明为782件(授权为107件)、实用新型为334件。
同美国、日本、中国以及和其他国家一样,欧洲的一部分国家也宣布了关于采用推广电动车的大胆的计划,包括财政激励、资助电池和电动车的研究、还有关于充电基础设施的调配分布计划。
像伦敦和巴黎这样的主要城市已经宣布了电动车共享系统,而拥有大型自有车队的公共管理部门和公司需要采购电动车。
与此同时,公用事业、汽车制造商、电池生产商和学者等共同参与发起了如欧盟电动汽车工作队和EpoSS——欧洲技术平台的智能系统一体化等项目。
协同欧洲投资银行一起,欧盟委员会已经推出了欧洲绿色汽车计划,这50亿欧元将部分地投入在电池和电动车的研究、开发、制造、以及示范项目上。
这一阵活动似乎表明,电动汽车最终将是一个重大突破。
但是这次,它会在这里停滞不前吗?历史告诉我们要谨慎。
电动汽车早在1883年就开始生产了——比内燃机汽车早52年。
然而,1913年以后,内燃机的大规模商业化导致电动汽车快速下降。
在过去几十年里,尝试重新引入电动汽车的努力大部分未获成功,它们仍然代表一个非常小的利基市场。
电动汽车未来发展的重大问题之一是电池性能的改良速度。
钗电池严重限制了电动汽车的性能,因为相比内燃机汽车,钗电池为整个汽车平添了220公斤的重量。
当今的大多数客用汽车都在城市行驶,因此在通常情况下路途较短、速度较慢,所以这一问题似乎并不像欧美等其他市场那样严峻,因为那里的平均行驶路程更长,最高速度也更快。
电动汽车技术的持续研发正大幅改善着汽车的性能。
美国A123Systems公司,世界最大的高能钗电池生产商之一,宣布汽车每次充电后,电池能够驱动汽车行驶200公里。
东芝公司最近也宣布正式推出超级充电电池,而这种电池在j分钟以内就可以充满90%的电量。
但是今天,未来看起来更加光明:电池技术已经取得许多重大进展,电动车有望在未来几年内大规模重新进入市场。
基于适度增长情况的假定,到2050年,电动车会在新销售额中占有超过60%的比例,并构成25%的全球汽车车队。
不过,由于现在还有一些相关技术开发和未来消费者行为的不确定性,对未来部署规模的估计会有很大变动。
电动汽车的一大好处是减少排放到大气中的温室气体。
当我们计算可替代能源动力汽车技术的碳减排总量时,不仅计算机车排放的CO2总量,而且还包括机车在整个生命周期的排放数量,从发电直到燃料运输时产生的CO2排放都包含在其中。
2008年8月,麦肯锡全球团队研究了北美、欧洲、中国和印度的乘用车行业。
团队基于现有技术和商业运行可行性选取并研究了四种可替代能源汽车技术。
他们通过与传统的消耗汽油或柴油的内燃机(ICE)汽车进行对比。
改良型汽油和朱油动力汽车:传统内燃机(ycE)汽车采用了减排技术,如采用有助于引擎高效燃油的可变换阀门控制、通过降低摩擦节约燃料的低滚动阻力轮胎。
改良型内燃机动力汽车在其生命周期中可能减少51%的碳排放量。
全混合动力汽车:全混合动力汽车主要消耗汽油,而在加速时以电池驱动。
汽车的动力来源主要依靠内燃机。
再加上上述内燃机改进技术,全混合动力汽车在其生命周期中可能减少50%的碳排放量。
压缩天然气(CNG)汽车:压缩天然气汽车一般被认为是采用清洁能源的车型,但在其生命周期中的碳减排空间完全取决于天然气来源——天然气运输距离越远,该车型“从油井到油箱”的排放量就越。
假设天然气来自当地气源,压缩天然气汽车在生命源大周期中碳减排量和混合动力汽车接近,为55%。
电动汽丰:电动汽车包括插电混合动力汽车(PHEV)和电池电动汽车(BEV)。
与全混合动力汽车相比,插电混合动力汽车装有更大的电池,因此使得汽车可以在没有内燃机的辅助下所行路程更远。
这种汽车可以用标准插座充电,只需内燃机提供少许动力。
电池电动汽车一直要电池提供动力,而不需要内燃机机制的帮助。
可虑到中国依赖谋电站发电,当今的电动汽车依靠现在的内燃机技术只能够有减少19%碳排放量的空间;然而,如果在电力供应方面使能源构成更加多元化,并向可替代能源转变的话,碳减排量会增加至49%。
虽然电动汽车具有零尾气排放的特点,但是,在电力生产过程中会有排放。
比如说,倘若没有采用新动力汽车技术的协同行动,中国乘用车的CO2排放水平到2030年可达12亿吨。
然而,我们的研究显示,中国可以通过采用各种可替代动力汽车技术实现高达45%的乘用车减排量。
对比其他的动力汽车技术,电动汽车的减排空间似乎较小。
全混合动力汽车的减排量可达56%,但是电动汽车只有19%的减排空间。
原因是中国仍然依靠火电站提供高达85%的电量供应。
但是,如果可替代能源到2030年占中国电力供应的50%,那么电动汽车的碳减排空间则可提高至49%,即大体上与其他技术的减排水平相当。
原因是,中国仍然依靠火电站提供高达85%的电量供应。
由此也可以衍生出电动汽车的一个另一个好处是将城市中有害的空气污染“位移”到农村地区,那里的人口暴露较低;噪音水平也较低,特别是在城市的驾驶条件。
电动车的另一个主要优势是能源效率。
拥有60%—80%的“油箱到车轮”效率,使得电动车优于传统汽车四倍。
总的来说,电动车在低速和频繁换挡的情况下显示出了强大的节能功效,这也是城市成为主要目标市场的另一个原因。
电动汽车也将为软件开发商带来机遇。
电力机车需要安装提示司机有关汽车重要数据状态的电子界面,包括燃料电池的使用情况、GPS导航系统的每秒更新等等。
由风险投资支持的新兴公司Better Place正在开发一种名为AutOS的综合信息管理系统,该系统可以告知司机最近的电池充电站的位置以及其他信息。
虽然燃料电池和其他相关技术在大幅降低CO2排放量方面前景广阔,但是其商业应用仍尚需时日。
然而,投资电动汽车并不意味着汽车制造商和供应商应该停止对其他技术的研究。
反而,他们应该保持一种平衡的技术组合,即将电动汽车作为近期的解决方案,而将其他技术,如燃料电池等,视为长期的解决方案。
因为一旦上述技术具有商业可行性时,将会带来可观的回报。
感谢其能源效率,如果发电在未来将更加环保,电动汽车将有助于温室气体的大幅减少。
鉴于对气候变化进行的考虑,这可能被证明是一个重要因素。
事实上,交通对欧盟的温室气体排放量需要负五分之一以上的责任,并且它是排放量不断增长的唯一部门。
虽然改善内燃机仍有可能减少每公里驾驶的排放量,但要使温室气体排放减少50%以上,就需要新的技术解决方案,如电动车。
相对于传统的汽车,并在目前欧洲平均电力供应的基础上,电动汽车有50%的更少的排放量。
如果随着更多的绿色和可再生能源的使用,发电的碳强度持续下降,则可以进一步获益。
电动车似乎终于到了发生重大突破的临界点,尤其是它能够在城市中提供巨大的环境效益。
创新的商业模式即将到来,这必将提升消费者的接受度。
然而,绿色电力供应仍存在一些障碍:昂贵的电池技术,有限的驾驶范围,和对于电动充电设施密集网络的需要。
为了克服这些障碍,创新的商业模式正在发展,以便助于转变汽车运输。

These include fiscal incentives, funding research on batteries and electric vehicles and plans for the deployment of a charging infrastructure. Major cities such as London and Paris have announced electric car-sharing systems, while public administrations and companies using large captive fleets are purchasing electric vehicles.At the same time, utilities, car manufacturers, battery producers and academics are joining forces on initiatives such as the EURELECTRIC Task Force on Electric Vehicles and EpoSS, the European TechnologyPlatform on Smart Systems Integration. Together with the European Investment Bank the European Commission has launched the European Green Cars Initiative, with EUR 5 billion partly dedicated to the research, development and manufacturing of batteries and electric cars and to demonstration projects.This flurry of activity seems to indicate that the electric car is heading for a major breakthrough at last - but is it here to stay this time? History calls for caution. The production of electric vehicles began as far back as 1838 – 52 years before combustion engine vehicles. However, after 1913 the mass commercialization of the combustion engine led to a rapid decline in electric vehicles. Attempts to reintroduce electric vehicles in past decades have for the most part been unsuccessful and they still represent a very small, niche market.One of the biggest issues facing the potential take-up of electric vehicles is the rate of improvement in the performance of electric vehicle batteries.The biggest drag on electric vehicle performance comes from the lithium-ion battery, which can add another 220 kilograms to the total weight of a car, versus an ICE-powered vehicle.Since most passenger vehicles in China today are driven in urban areas, where shorter distances and slower speeds are the norm, this may not prove to be as vexing an issue as it is in other markets such as the US or Europe, where the average driving distance and top speed are considerablylonger and higher. Continued research and development into electric battery technology is generating promising improvements in performance. US-based A123Systems,one of the world's largest producers of high-power lithium-ion batteries,Announced a battery capable of powering a car for 200 kilometers between charges. Toshiba recently announced the commercial launch of its Super Charge battery, which can be charged to 90 percent capacity in less than five minutes.Yet today the future looks brighter. A great deal of progress has been made in battery technology and electric vehicles are expected to re-enter the market on a large scale within the next couple of years. Based on a moderate growth scenario, by 2050, electric vehicles could represent more than 60%of new sales and constitute up to 25% of the global car fleet. However, estimates of the extent of future deployment vary greatly, as there is still some uncertainty in relation to the development of technology and future consumer behavior.One of the primary benefits of electric vehicles is, of course, the reduction of Green house gases emitted into the atmosphere. Our calculation of the total carbon abatement potential of alternative power train technologies counted not only the CO2 emissions that vehicles produce, but also emissions produced through out their entire life-cycle, from the CO2 emitted during the generation of electric power through to the transportation of fuel.Over a period of 8 months in 2008, a global McKinsey team studied the passenger vehicle industries in North America, Europe, China, and India. The team examined four power train technology alternatives, chosen on the basis of existing technologies and their near-term commercial feasibility. They contrasted them to conventional internal combustion engine (ICE) vehicles that run on gasoline or diesel.Full hybrid vehicles: Running primarily on gasoline, full hybrids are powered by a battery during acceleration of the vehicle, but draw most of their power from an internal combustion engine. Full hybrids, equipped with ICE improvement technologies mentioned above, have a life-cycle carbon abatement potential of 56 percent.Compressed natural gas (CNG) vehicles: CNG vehicles are normally perceived to be a source of clean energy, but their life cycle carbon abatement potential depends wholly on the source of the gas一the greater the distance the gas needs to be transported, the higher this power train's "well-to-tank" emissions. CNG cars rank close to hybrids in their life-cycle carbon abatement potential at 55 percent, assuming the gas comes from local sources.Electric vehicles: Electric vehicles include plug-in hybrid vehicles (PHEV) and battery electric vehicles (BEV). Compared with full hybrids, plug-in hybrid vehicles contain a much bigger battery that can power the vehicle for a longer distance without the aid of an internalcombustion engine, can be recharged by plugging them into standard electric sockets, and derive a smaller proportion of their propulsion from the internal combustion engine. Can be recharged by plugging them into standard electric sockets, and derive a smaller proportion of their propulsion from the internal combustion engine. Battery electric vehicles run solely on battery power without the aid of any internal combustion mechanism. Given reliance on coal-fired plants for electricity.electric vehicles today only have a 19 percent carbon abatement potential over current internal combustion engine technologies; however, this can be increased to as much as 49 percent if diversifies its energy mix towards alternative energy sources for its supply of electric power.Electric vehicles have zero tailpipe emissions, but there are, of course, emissions involved in the production of electricity. As an example,with no concerted action to adopt new power train technologies, the level ofCO2 emissions from passenger cars in China could reach nearly 1.2 billion tons in 2030. However, our research showed that by adopting a mix of various alternative power train technologies, China could cut emissions from passenger vehicles by up to 45 percent. Relative to other power train technologies, electric vehicles demonstrate a some what weaker carbon abatement potential. While full hybrid cars have an abatement potential of 56 percent, electric vehicles' potential stands at 19 percent. This can be explained by the factthat China still relies on coal-fired plants for as much as 85 percent of its electricity supply. This can be explained by the fact that China still relies on coal-fired plants for as much as 85 percent of its electricity supply.It also can blossom into another electric car benefits of electric vehicles is the “displacement “of harmful air pollutants from urban to rural areas, where population exposure is lower. Noise levels are also lower, particularly in urban driving conditions.Another major advantage of electric vehicles is their energy efficiency. With a tank-to-wheel efficiency in the range of 60 to 80 %, they outperform conventional cars four-fold. Generally, electric vehicles show greatest energy savings at low speeds and in situations involving frequently-changing driving dynamics, which is another reason why cities are a prime target market.Electric vehicles will also create opportunities for software developers. Electric vehicles require an electronic interface that informs the driver of the status of the car's vital statistics, from fuel and battery usage, to split-second updates in GPS navigation systems. Venture-backed start-up Better Place is developing a comprehensive information management system it calls AutOS.that will, among other things, inform the driver of the nearest battery-charging stations.While other technologies such as fuel cells hold great promise inreducing CO2 emissions, its commercial application remains years away. Investing in electric vehicles, however, does not mean Chinese OEMs and suppliers should stop their research into other technologies. Rather, they should maintain a balanced technology portfolio, with electric vehicles being a near-term solution, while viewing other technologies such as fuel cells as a potential long-term solution that could yield returns once the technology becomes commercially viable.Thanks to their energy efficiency, and assuming that electricity generation will be even greener in the future, electric vehicles could contribute to a considerable reduction in greenhouse gases. Given the ongoing debate on climate change, this could prove to be an important factor. Indeed, transport is responsible for more than a fifth of the EU’s greenhouse gas emissions and it is the only sector with growing emissions. While the improvement of internal combustion engines still offers considerable potential for reducing emissions per kilometer driven, reductions in greenhouse gas emissions over and above 50 % will require new technological solutions, such as the electric vehicle.Compared to conventional vehicles, and based on the current average European electricity supply, electric vehicles have 50 % less emissions. Further benefits can be achieved if the carbon intensity of power generation continues to decrease with further greener and renewable energy sources.The electric car finally seems to be on the verge of breaking through, offering significant environmental benefits, especially in urban areas. There are, however, still some obstacles related to green electricity supply, the as yet expensive battery technology, the limited driving range and the need for a dense network of electric charging facilities. To overcome these obstacles, innovative business models are being developed to help transform automotive transport.。
