推动新能源产业发展的作文

推动新能源产业发展的作文英文回答:As an advocate for the development of new energy industries, I firmly believe that the promotion of new energy industries is not only an urgent need for sustainable development, but also a strategic choice for economic transformation. The development of new energy industries is of great significance for promoting energy conservation, emission reduction, and environmental protection, and it is also an important measure to promote energy revolution and industrial transformation. In recent years, with the continuous improvement of new energy technologies and the continuous decline in costs, new energy industries have shown great potential and broad prospects for development.First of all, the promotion of new energy industries can effectively alleviate the pressure of resource and environmental constraints. Traditional energy sources suchas coal, oil, and natural gas are non-renewable resources, and their excessive exploitation has caused serious environmental pollution and ecological damage. In contrast, new energy sources such as solar energy, wind energy, and biomass energy are clean and renewable, and their development and utilization can effectively reduce the emission of greenhouse gases and pollutants, and alleviate the pressure of resource and environmental constraints.Secondly, the development of new energy industries can drive the transformation and upgrading of traditional industries. As new energy technologies continue to mature and costs continue to decrease, new energy industries such as photovoltaic power generation, wind power generation, and electric vehicles have shown strong market competitiveness. The development of new energy industries has driven the transformation and upgrading of traditional energy industries, promoted the integration and innovation of energy technologies, and injected new vitality into the development of related industries.Furthermore, the promotion of new energy industries cancreate new economic growth points and enhance the international competitiveness of the economy. The development of new energy industries has a strong driving effect on the development of related industries such as equipment manufacturing, construction, and finance, and has created a large number of new jobs. At the same time, the development of new energy industries can reduce the dependence on traditional energy imports, enhance energy security, and enhance the international competitiveness of the economy.中文回答:作为新能源产业发展的倡导者,我坚信推动新能源产业发展不仅是可持续发展的迫切需要,也是经济转型的战略选择。

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。

关于新能源的英语作文英文回答:New Energy: A Promise for the Future。

In the face of the global climate crisis and dwindling fossil fuel reserves, the development and adoption of new energy sources have become imperative. These energy sources offer a sustainable and environmentally friendlyalternative to traditional fossil fuels, reducing our dependence on finite resources and mitigating the adverse effects of climate change.One of the most promising new energy sources is solar energy. Solar panels harness the power of sunlight to generate electricity, providing a clean and renewable source of energy. Solar energy is abundant, widely available, and has minimal environmental impact. As the technology continues to advance and costs decline, solar energy is becoming increasingly cost-effective andaccessible.Another important new energy source is wind energy.Wind turbines convert the kinetic energy of wind into electrical energy. Wind energy is also renewable, abundant, and has low operating costs. However, wind turbines canhave a visual impact on landscapes and may pose risks to wildlife.Hydropower is another widely used renewable energy source. Dams capture the energy of moving water to generate electricity. Hydropower is a reliable and cost-effective source of energy, but it can have significant environmental and social impacts, including the displacement of communities and disruption of ecosystems.Geothermal energy harnesses the heat from the Earth's core to generate electricity or provide heating and cooling. Geothermal energy is a reliable and baseload source of energy, but it is only available in certain regions with suitable geological conditions.Nuclear energy is a low-carbon energy source that can provide a reliable and continuous supply of electricity. However, nuclear energy raises concerns about safety, waste disposal, and proliferation. The development of new nuclear technologies, such as small modular reactors, could potentially address some of these concerns.In addition to these established new energy sources, researchers and scientists are continually exploring and developing new and innovative energy technologies. These technologies include energy storage systems, such as batteries and flywheels, which can store excess energy for later use; tidal and wave energy, which harness the power of the ocean; and hydrogen fuel cells, which produce electricity through a chemical reaction between hydrogen and oxygen.The transition to new energy sources is not without challenges. These challenges include the need for significant investment in infrastructure, potential job losses in the fossil fuel industry, and the need to address public concerns and perceptions. However, the benefits ofnew energy far outweigh the challenges. By embracing new energy sources, we can secure a sustainable and prosperous future for generations to come.中文回答:新能源,未来的希望。

新能源经济【外文翻译】

(2011届)本科毕业设计(论文)外文翻译原文:THE NEW ENERGY ECONOMYEveryone agrees it's time, but the obstacles go well beyond matters of technology. Why real change will take nothing less than a new American revolutionTo describe what's needed to wean the country off fossil fuels, people often use the word transition. But transition is too smooth. It suggests steadiness, even inevitability, as if the endpoint is predetermined.The outcome of the tremendous push that's now underway to change how the United States and other countries obtain and consume energy is anything but predetermined. There are no definite answers to questions about the role one source of energy or another will play 15 or 20 years from now, no clear sense about the type of fuel (if any) people will put in their cars, no consensus on how quickly any of this can happen or at what cost.Nor is the change likely to be smooth and quiet. Instead, it will probably be disruptive, breaking down existing ways of thinking and acting. Not that disruption is bad: Joseph Schumpeter, the famous Austro-Hungarian economist, once spoke of "creative destruction," whereby new technologies and ideas replace old ones, which themselves are overthrown by newer, more progressive ones.Already, 2009 has been a year of visions, of prophecies. President Barack Obama's inaugural address offered one such vision: doubling alternative energy production in the next three years, updating and expanding the nation's energy infrastructure, saving billions of dollars in energy costs through improved energy efficiency. Think tanks, businesses, industry groups, and environmentalists have laid out their own plans, some more aggressive and some less so.The sheer number of these plans, not to mention the interest percolating up from nearly all corners of American life, suggests, as Energy Secretary Steven Chu puts it, that "the landscape is changing."Clean energy is, of course, a narrative that has been slowly developing in the UnitedStates over the past four decades or so, at least since President Jimmy Carter's administration. In the past, its visibility and its urgency have ebbed and flowed with the price of oil. Today, however, it's not just the wild fluctuation in oil prices that is driving the discussion. There is the economic crisis. There is the burgeoning climate crisis, with its implicit call for global cooperation. And there are fresh concerns about national security in an age of emboldened oil cartels and nuclear ambitions. Addressing each of these priorities raises its own set of questions. At the moment, there is no consensus on how aggressively the United States should reduce greenhouse gas emissions over the few next decades or, more broadly still, the proper role of fossil fuels and renewable energy.Meanw hile, almost every potential contributor to a “green energy economy"--wind and solar power, befouls, nuclear power, energy efficiency--faces hurdles well beyond the technology of each system. Regulatory policies or economic issues stand in the way of massive, quick deployment of any of these.And so, today, a new mentality is emerging among almost all the major energy players, from wind developers in the Dakotas to coal-plant operators in North Carolina: Energy issues can no longer be treated as piecemeal policy items left up to states and hodgepodge federal legislation to decide but instead must be addressed nationally, in a sweeping manner.Want the country running on flex-fuel vehicles? "It's just a few hundred dollars more per vehicles," says retired Gen. Wesley Clark, the 2004 presidential candidate and now cochairman of Growth Energy, a group representing several of the nation's largest ethanol producers. "What would encourage an automobile manufacturer to believe he should do it would be a government policy that says we are moving in that direction."Want more wind power? "The critical thing we are talking about here is national policy and the signals it sends to people," says Denise Bode, CEO of the American Wind Energy Association. "There is tremendous demand for wind power, but there is not enough transmission."The idea that a nation should have a clear-cut national energy policy sounds obvious enough. In the United States, however, the truth is that energy has not always beenconsidered a national issue, and in some ways it still isn't.Nowhere is this more obvious than with the transmission grid, a sprawling jumble of wires and mechanical connections dating back 50, 80, even 100 years in some places. Today, the grid is divided into more than 140 "balancing areas" to help manage the distribution of power. But some are so localized that they can't communicate with their next-door neighbors. As a result, extra power in one region is often wasted rather than being sent to a place that needs it.So if wind power, solar power, and plug-in electric vehicles are to be big players in the country's energy future, as many hope, this antiquated system for delivering electricity will have to change. The grid must be retooled, and new high-capacity power lines are needed to carry wind-generated electricity from the Midwest to the East and West coasts. To get those high-power lines approved, Bode and other advocates say, the federal government needs more authority to override nasty squabbles between states, environmentalists, and other interest groups that have typically stalled such efforts. The federal government, the thinking goes, already has the authority to build natural gas pipelines across state lines, and electricity should be no different. That sentiment seems to be gaining ground even among regulators who once opposed it, although there are many issues still to be worked out. As Chu says, "If we just take the view that we are going to cram something down someone's throat, this is not a constructive way of doing business" (interview, Page 32). Infrastructure is only one part of the battle to make national energy problems a national issue. Another is technology. Even though wind power technology is relatively mature--it was the country's largest provider of clean electricity last year--most other renewable sources still need work. Improvements to photovoltaic cells could reduce solar power costs significantly. New drilling technologies could help geothermal spread across a larger geographic range. Advancements in befouls, in particular to the enzymes needed to break down grasses and woods to produce ethanol, would have a major impact. Meanwhile, fossil fuels face their own technological challenges. If coal is to stay around for a while, it'll most likely be because of still-developing methods to capture carbon dioxide emissions before they enter the atmosphere.Scientific breakthroughs don't come cheap. The economic stimulus package set aside $21.5 billion for scientific research, signaling that Washington is taking a much more active role in basic energy issues after years of declining budgets at national labs. But this is just the groundwork. The most powerful force to remake the energy America uses could be government policies: climate change legislation, which would set a price on carbon dioxide emissions, and a national renewable-electricity standard, which would require the United States to get a certain portion of its electricity from renewable energy. Both rules could have far-reaching impacts, forcing industries to massively reconsider their operations, giving financial investor’s confidence to pump money into wind farms, solar fields, and other industries, and convincing the coal industry that it's worth investing billions in technology to reduce emissions.The consequences of climate change legislation, in fact, are expected to be so great that companies typically opposed to government regulation are asking Congress to go ahead and act just so that they can have some certainty about where to put their money.What Washington won't do--not in theory, anyway--is pick specific winners. "The market will decide what the mix will be," says Matt Rogers, a former director at McKinsey & Co. and now one of Chu's top advisers. "It will be interesting to see what the market brings forward." Of course, in reality, Congress's record is one of subsidizing some industries but not others. Even within the befoul world, corn-based ethanol is heavily supported, but some others, such as befoul made from algae, receive almost no backing.In this new era of national energy, one of the primary questions facing the country is that of timing. When should things happen? And how soon can they occur? "Broadly, what scares me is that we want to do this in an incremental fashion. We want this to come across as painlessly as possible," say Rich Wells, vice president of energy at Dow Chemical. "We need a breakthrough mentality."It has become a cliché to say that there is no "silver bullet" for the nation's energy and climate problems. Most experts prefer to think about energy solutions as a collection of options to be deployed in tandem. Perhaps the most widely quoted example is the "wedge model," developed by Princeton University professors Stephen Pocola andRobert Soochow in 2004. It outlined 15 wedges, each one representing a way to significantly reduce greenhouse gas emissions over the next 50 years. Among them: raising the fuel economy of 2 billion cars from 30 mpg to 60 mpg and doubling nuclear capacity worldwide.Only some of these, of course, are realistic in the shorter term. "If you're only going to do one, the top one is always energy efficiency," says Dow's Wells. "It is for the most part the easiest, cheapest fuel out there." Amory Loins, chief scientist at the nonprofit Rocky Mountain Institute, agrees, saying that energy savings from highly fuel-efficient cars would be equivalent to "finding a Saudi Arabia under Detroit." Perhaps the biggest barrier for buildings has been the upfront cost of doing retrofits, with the need to convince people that the costs can be quickly recouped by lower energy bills. The stimulus package is taking a stab at this, setting aside $5 billion for home weatherization.Meanwhile, everyone else is jockeying for position. The befoul industry wants Congress to lift the cap on how much ethanol can be blended into gasoline. The nuclear industry is asking Congress to cough up billions to insure new nuclear power plants; wind and solar industries are asking for transmission superhighways. Detroit wants more in government bailout money. And coal wants money to research carbon capture technology. The great energy nationalization is here.译文:新能源经济每个国家都希望开发新能晕,但局限于开发的障碍以及技术问题。

(节选)新能源材料外文翻译--存储锂离子的层状硅中锂的吸收和扩散

(节选)新能源材料外文翻译--存储锂离子的层状硅中锂的吸收和扩散
我们在GPAW代码的基础上计算总能量,一个根据突出增强波措施的基于网格的方法。对于交换和相关的描述,我们使用Perdew−Burke−Ernzerhof泛函数。我们还进行计算局部范围内的密度近似值,我们发现,在计算出的原子结构的相对稳定性没有差别。一个6×6×1特殊点的Monkhorst-Pack网格是用于倒易空间的整合。对于结构的最优化,原子的力的大小被最小化,以低于0.04电子伏特/ 埃的限制。为了得到扩散途径和相应的能量壁垒,我们进行标准微应通路与NEB路径,由8个中间配置。NEB路径第一次构建出来是通过原子坐标的线性插值,直到附在每个原子上的力小于0.04eV/埃的大小。通过优化配置之间的多项式插值得到连续的扩散路径。
我们首次讨论单层硅酮吸附的情况(图2)。对于一个单一的在单元格(SL-Li0.11Si0.89)的锂吸附原子,最稳定的吸附部位是中空部位,其中,Li存在于六方硅烯环的中心,它具有三个最邻近硅原子。相应的吸附能为2.08电子伏特(2.13和2.21伏特这个能量值在前面的理论研究中已报道)。
为了评估作为用于锂的主体材料的硅烯的适用性,我们在这项工作中使用基于密度泛函理论的第一原理计算,在模型中研究锂和硅的局部相互作用,以及无依附的单层和双层硅烯结构的相互作用。理论计算可以提供原子级的观察大量锂的扩散运动和硅二维结构,这是难以通过实验手段来获得的。具体来说,我们确定锂的结合位点,我们计算出扩散能垒。我们发现,作为锂容量和硅层的数量(一个或两个)的函数,结合能(2.2 eV /每个锂原子)表示微小的变化,并且锂的扩散能垒相比较于在体积硅中的扩散和薄的硅纳米线往往更小(<0.6eV)。
关键词:锂离子电池,储能,二维硅,原子吸附,表面扩散,初始计算
锂离子二次电池构成一个有前途的适合于便携式和网格应用的能量储存技术。其能量密度极大程度上取决于构成电极的具体充电容量。因为高的理论比容量,对硅基阳极进行了研究,以代替现有的石墨阳极(4200毫安每克),虽然硅的伴随电池操作和随后降低的充电速率的降解限制了这种电池技术的商业化。在与流行的单层和少数层二维层状材料的制备中,被称为“硅烯”的硅的石墨烯状结构最近普遍有报道。硅烯合成的控制随着迄今对各种金属基材样品的制备得到持续不断地改进,例如,银,铱,和ZrB2。此外,还有一个正在进行的尝试,以便通过理论和模拟的属性更好地了解低维硅。由于其比表面积大,硅烯可以作为锂离子二次电池的高容量宿主。在这个大背景下,锂和单层及多层硅烯的相互作用在很大程度上仍然未涉及。

China’s Biomass EnergyChina leads the world in its energy reservation and is the second largest energy producer and consumer in the world. It is estimated that China has 4000 billion tons of potential primary energy reservation. However, per capita energy resource quantity and consuming quantity is far smaller than the world average level. The main characteristics of China’s energy exploration and utilization are as follows.1. Coal is the primary energy; exploration and utilization of renewable resources is supplementary. China’s explored reserves of coal resource accounts for over 90% of the primary energy total, such as coal, oil, natural gas, water energy and nuclear energy. Coal is dominant id China’s energy production and consumption.on.2. Energy consumption volume is increasing while energy utilization efficiency is comparatively low. As the economic scale expands, China’s energy consumption is on the constant increase. Under the influences of capital, technology, energy price, etc, China’s energy utilization efficiency is far lower than that of the developed countries. Energy comprehensive utilization efficiency is 32% and the overall energy systematic efficiency 9.3%. These numbers are only half of the developed country level.3. With the sustained increase of energy consumption, the coal-dominant energy structure has caused urban air pollution while with the excessive consumption of bio-mass energy giving rise to ecological destruction, the pressure on ecological environment is more and more severe. According to the World Bank, the economic loss caused by air and water pollution in China, approximately accounts for 3%--8% of GNP.4. The energy structure is getting more and more pluralized. By the middle of the 1990’s, energy self-sufficiency rate was 98%, while at present China is the second largest crude oil importer only after USA.The rapid development of China’s economy is based on the sufficient supply of energy, however, the higher-than-normal oil price on the international market together wit h China’s ever-increasing energy demand will be a serious subject faced withChina’s development road.More than 3200 places of terrestrial heat have been discovered in China, 225 of them could be used for power generation. It is estimated that the exploitable reserve of terrestrial heat in China is equal to the power of 462.65 billion tons of standard coal. In recent years, the use of terrestrial heat in our country has increased by 7%. We have usedChina will adopt the sustainable energy development str ategy of an “energy saving prioritized, plural structured, and environment friendly” nature in the coming 20 years. We will adopt the international energy strategy and strive to quadruple GDP with double energy consumption with the help of mechanism innovation and technological advancement. The following specific goals are expected to reach under the sustained energy development strategy: energy consumption of per unit GNP will be reduced by 20% on the level of the end of the 10th five-year plan; primary energy demand will be less than 2.5 billion tons of standard coal by 2020, saving 0.8 billion tons; coal consumption ratio is controlled under 60%, renewable energy utilization reaches 525 million standard coal (power generation by renewable energy stands at 100 million kilowatt); oil importing reliance is controlled under around 60%; the reduction rate of main pollutants is 45%--60%.The Development of New Energy in ChinaNew energy and renewable energy only started to develop in China. As pointed out in the Annual Report of China’s New Energy Industry released in January, 2007, China will largely increase the rate of new energy such as wind power, solar power, and biomass power in the overall energy consumption. The report says, our first step is; the new energy installed capacity will be 120 million kw by 2020, that is 12% of China’s total installed power capacity. We will have a boost of power generation by using wind, bio-energy and solar energy. The second step is; the percentage of new energy consumption will increased dramatically comparing to other kind of energies. By 2050, the new energy will account for 30%--40% of the total energy demand of China. Now l would like to give you a brief introduction on wind power, biomass energy, solar energy and terrestrial energy in China.Wind PowerThere are abundant wind power within our huge territory and along our long coastline. According to the survey of China meteorological Academy, based on the results of 900 weather stations, there is 253 million kw of wind power reserve 10 m below our earth. There is a great potential of wind power in the coastal area of eastern China 2---15 meters below sea level. Therefor ,we have a promising future in wind power generation there.Compiled by China Energy Comprehensive Use Association and European Wind Power Society, in a Report named Wind Force 12 in China, it is expected that China will have 40 million kw of wind power capacity in 2020, if is could develop fully. Then, the wind power will go beyond nuclear power and become the third largest power source in China. If that is true, China’s annual wind power generation would go up to 80 billion kwh, it could be enough for 80 million people. Meantime, it would reduce 48 million tons of CO2 emission.The report also says that China will need over 25 thousand of large wind generators by the year 2020, wind power sale will increase to morethan 300 billion yuan, that will create at least 150 thousand of job opportunities. It indicates that in the past 5 years, the cost of wind power will reduce by 20%, its technology cost is one of the lowest which can be decreased among the renewable energies.Biomass energyAccording to the Outline for Mid-- long Term Development of Renewable Energy in China, the goal of renewable energy development in the next 15 years is; by 2020, the renewable energy will occupy 16% in the energy structure of China. Among them, the production of ethanol is going up to 10 million tons; bio-diesel fuel 2 million tons; and the major part of the biomass energy development target are bio-energy power generation, Firedamp projects biomass liquid fuel and Biomass solid fuel. The biomass project in China has made great progress now, but it is still in an initial stages.According to the Supporting Policy of Bio-energy and Bio-chemistrydevelopment jointly promulgated by several ministries, China will give favorable treatments to support biomass energy development in the following aspects: setting up risk fund system, providing flexible loss subsidy; subsidies for raw material bases and demonstration projects; tax reduction is included. We can predict that the biomass energy in China will be developed rapidly in years to come.Terrestrial Energy12604.6 GWH of terrestrial heat till 2005 with an installed capacity of 3687 MWT, which rank number 1 and number 3 in the world respectively.We use the high heat to generate power and low middle heat to daily purposes. three thermo-power plants have been build in Tibet now, the total installed capacity in China is 29 mw. Terrestrial heat Floors have seen both economical and environmental benefit in the northern part of China as well as in big or medium cities such as: Beijing, Tianjin, Xi’an and Anshan. It is growing fast in agricultural areas like green house (terrestrial),breed aquatics, irrigation, in health care, recreation and tourism ,too China tops the world in utilization of terrestrial heat, but it is only 0.5% of our total energy. Terrestrial power is only 0.35% of the world total generation. We still have a long way to go in developing and utilizing the terrestrial heat.Ocean EnergyExperts have pointed out, while we are exploring petroleum, natural gas, coal and petrification energy, China ought to focus on the future, exploring the promising ocean energy. The clean, renewable ocean energy is the key source of solving the global energy problem, exploiting of ocean energy has been aroused much attention in USA, UK and Australia, some of the experiments have entered a phase of trial operation and evaluation. However, China, Japan and other eastern Asian counties have not realized the true meaning of ocean energy exploration.China’s Energy StrategyIn order to achieve the goal of building a well-off society and face the severe challenge of the long-term energy development, it is of overriding significance for China to adopt the right energy development strategy. Drawing upon the successful experiences of the developed countries and also proceeding from its nationalcondition, China will establish a long and middle term sustainable energy strategy that is in accordance with increasing energy efficiency and protecting the environment.中国的生物质能源中国的能源蕴藏量位居世界前列,同时也是世界第二大能源生产国与消费国。

(节选)新能源材料外文翻译----Ti3C2  MXene作为金属(Li、Na、K、Ca)离子电池的高容量电极
二维材料作为金属离子电池的主要材料具有特殊性,归因于它们独特的形态学特点,表面完整的暴露可以加快离子扩散和提供更多的离子插入通道。最近,二维早期过度金属碳化物和碳氮化物的一个族系通过MAX相的原子在室温下使用氢氟酸(HF)选择性刻蚀的方法被合成,称为“MXenes”。MAX相是三元金属碳化物的一个很大的族系(超过60个相),成分为Mn+1AXn,其中M是一个早期过度金属,A是A组基础元素之一,X是指碳或者氮,n可以是1或2或3。目前,下列MXenes已用试验方法合成:Ti3C2,Ti2C,(Ti0.5Nb0.5)2C,Ta4C3,(V0.5Cr0.5)3C2,Ti3CN,V2C和Nb2C。由于这些发现,MXenes赢得了很大的关注并且呈现出有趣的性能。例如,多层MXenes的导电性可与多层石墨烯相比拟。在MXenes系统的实验发现之后不久关于不同性能的理论研究也开始了。Shein和Ivanovskii曾研究其结构特点和MXene Tin+1Cn与Tin+1Nn(n=1,2,3)之间的稳定性关系。密度泛函理论(DFT)的计算显示MXenes在可调带隙作用下能够成为半导体,可调带隙可以通过改变表面终端来控制,但是没有终端的MXenes是金属的并且有希望拥有最高的导电性。Ivanovskiiet al.利用密度泛函理论估计出MXenes的内面弹性常数,超过了500GPa,这意味着MXenes有希望拥有比结构钢(400GPa)更高的刚性。
MXenes有希望成为锂离子电池和锂离子电容器的电极材料。尽管MXenes对于Li的容量与商业的石墨电极锂离子电池(372,mAh/g)相近,MXenes表现出杰出的处理高循环率的能力。例如,对于无添加剂终止的Ti3C2,在36℃的循环效率下,可获得110mAh/g的可逆容。注意,石墨不能处理这样的高循环速率。这是因为Ti3C2对锂原子C2(0.07eV)上的扩散势垒区比锐钛矿TiO2(0.35—0.65eV)和石墨的小。然而,电子性能的研究和MXenes的应用需要利用其它金属离子电池。目前还没有使用MXenes电极的钠离子电池或其它金属离子电池的数据被报道。在这篇文章中,我们选择Ti3C2作为例子和最佳研究MXene并且利用第一性原理密度泛函理论计算,就它作为不同金属(Li、Na、K和Ca)离子电池的电极材料表现的性能作报告。

发展新能源的英文作文

发展新能源的英文作文英文回答:Developing new energy sources is a critical imperative in today's world, as we face the increasing challenges of climate change and energy security. The transition to a low-carbon future requires us to move away from fossil fuels and invest heavily in renewable energy sources.There are numerous benefits to developing new energy sources.

作文范文之新型能源英语作文新型能源英语作文【篇一:新能源发电英语演讲比赛稿件】good morning. welcome to the lecture here today.i believe everybody may know or hear about nuclear power. regarded as a source of power, nuclear power is an important element of a diverse, clean energy and an important source of low-carbon electricity. increasing the amount of electricity generated by nuclear power is critical to move toward a more sustainable and securer energy in the future.according to statistics, nuclear power is the second largest source of domestic electricity in america, and the country is expanding nuclear power as a key energy source for long-term energy security. regardless of what the u.s. does, the world is increasingly turning to nuclear power as a low-carbon electricity source. all in all, nuclear power plays a significant role in cutting air pollution, and protecting national security.although nuclear power plays a growing role in meeting the world’s energy n eeds, nuclear power dangers will remain. the disastrous earthquake and tsunami in japan, which led to the nuclear accidents at the fukushima reactor, have brought safety to the forefront of the discussion on nuclear power. at the same time, terrorism is another threat to the development of nuclear power. once the nuclear power plant encounters terrorist attacks, the consequences would be disastrous. we have known for years that a nuclear accident anywhere is a nuclear accident everywhere, which leave us many inspirations and questions worthy of consideration: what is the trend for the development of nuclear power in the future, and how rational to carry on theutilization of nuclear power?we know that the nuclear accident in japan has raised questions about the development of nuclear power plant in countries around the world. some eu countries have announced the suspension of nuclear power facilities projects, particularly in germany, chancellor angela merkel intimated that germany would not prepare to establish nuclear power plants. it should be said, however, that every choice is both narrow and wide, so in nuclear power. we must recognize that there is no major energy source that can be exploited withoutrisk. as long as we prohibit the abuse of nuclear power, and improve security to make use of its favorable factors, nuclear power will take more active part in improving living conditions and the ecological environment rather than destroying our home.in my view, given the worlds fast-growing energy needs, nuclear power should be properly developed due to its specialty in energy shortage supplement and environmental pollution reduction. under the safe and security premise, site selection of nuclear power plant should be places away from the population centre and where there are few or no natural geological hazards, such as earthquakes. in the transition of energy utilization, nuclear power can assume a major role to supply the power generation, and its development can be constrained after the technology maturity of wind power, solar power and other new energy power generation.while working to encourage the peaceful use of nuclear power, we must seek the security of a world without nuclear weapons and a peaceful expansion of nuclear power. working cooperatively and with a shared sense of commitment and obligation, we can succeed in building a clean and safer energyfuture, and without this support, nuclear power will not be able to play the right kind of role which it can and should play in the global energy future. i look forward to working with all of you gathered here today to turn this vision into a reality, and ultimately leave our children with a stronger, bettercountry than when we found it.thank you and i’m happy to take some questions.【篇二:机械英语作文】mechanical engineeringmechanical engineering is the science of natural science and technology as the theoretical basis of technical production practice experience, research and address the development, design, manufacture, installation, use and repair of all machinery in the application of theoretical and practical issues disciplines. machinery of modern society, the five elements of production and services (people, capital, energy, materials and machinery) of, and participation in energy and materials production. any modern industrial and mechanical engineeringapplications are required, such as agriculture, forestry, mining and other necessary agricultural machinery, forestry machinery, mining equipment;

(2011届)本科毕业设计(论文)外文翻译原文:THE NEW ENERGY ECONOMYEveryone agrees it's time, but the obstacles go well beyond matters of technology. Why real change will take nothing less than a new American revolutionTo describe what's needed to wean the country off fossil fuels, people often use the word transition. But transition is too smooth. It suggests steadiness, even inevitability, as if the endpoint is predetermined.The outcome of the tremendous push that's now underway to change how the United States and other countries obtain and consume energy is anything but predetermined. There are no definite answers to questions about the role one source of energy or another will play 15 or 20 years from now, no clear sense about the type of fuel (if any) people will put in their cars, no consensus on how quickly any of this can happen or at what cost.Nor is the change likely to be smooth and quiet. Instead, it will probably be disruptive, breaking down existing ways of thinking and acting. Not that disruption is bad: Joseph Schumpeter, the famous Austro-Hungarian economist, once spoke of "creative destruction," whereby new technologies and ideas replace old ones, which themselves are overthrown by newer, more progressive ones.Already, 2009 has been a year of visions, of prophecies. President Barack Obama's inaugural address offered one such vision: doubling alternative energy production in the next three years, updating and expanding the nation's energy infrastructure, saving billions of dollars in energy costs through improved energy efficiency. Think tanks, businesses, industry groups, and environmentalists have laid out their own plans, some more aggressive and some less so.The sheer number of these plans, not to mention the interest percolating up from nearly all corners of American life, suggests, as Energy Secretary Steven Chu puts it, that "the landscape is changing."Clean energy is, of course, a narrative that has been slowly developing in the UnitedStates over the past four decades or so, at least since President Jimmy Carter's administration. In the past, its visibility and its urgency have ebbed and flowed with the price of oil. Today, however, it's not just the wild fluctuation in oil prices that is driving the discussion. There is the economic crisis. There is the burgeoning climate crisis, with its implicit call for global cooperation. And there are fresh concerns about national security in an age of emboldened oil cartels and nuclear ambitions. Addressing each of these priorities raises its own set of questions. At the moment, there is no consensus on how aggressively the United States should reduce greenhouse gas emissions over the few next decades or, more broadly still, the proper role of fossil fuels and renewable energy.Meanw hile, almost every potential contributor to a “green energy economy"--wind and solar power, befouls, nuclear power, energy efficiency--faces hurdles well beyond the technology of each system. Regulatory policies or economic issues stand in the way of massive, quick deployment of any of these.And so, today, a new mentality is emerging among almost all the major energy players, from wind developers in the Dakotas to coal-plant operators in North Carolina: Energy issues can no longer be treated as piecemeal policy items left up to states and hodgepodge federal legislation to decide but instead must be addressed nationally, in a sweeping manner.Want the country running on flex-fuel vehicles? "It's just a few hundred dollars more per vehicles," says retired Gen. Wesley Clark, the 2004 presidential candidate and now cochairman of Growth Energy, a group representing several of the nation's largest ethanol producers. "What would encourage an automobile manufacturer to believe he should do it would be a government policy that says we are moving in that direction."Want more wind power? "The critical thing we are talking about here is national policy and the signals it sends to people," says Denise Bode, CEO of the American Wind Energy Association. "There is tremendous demand for wind power, but there is not enough transmission."The idea that a nation should have a clear-cut national energy policy sounds obvious enough. In the United States, however, the truth is that energy has not always beenconsidered a national issue, and in some ways it still isn't.Nowhere is this more obvious than with the transmission grid, a sprawling jumble of wires and mechanical connections dating back 50, 80, even 100 years in some places. Today, the grid is divided into more than 140 "balancing areas" to help manage the distribution of power. But some are so localized that they can't communicate with their next-door neighbors. As a result, extra power in one region is often wasted rather than being sent to a place that needs it.So if wind power, solar power, and plug-in electric vehicles are to be big players in the country's energy future, as many hope, this antiquated system for delivering electricity will have to change. The grid must be retooled, and new high-capacity power lines are needed to carry wind-generated electricity from the Midwest to the East and West coasts. To get those high-power lines approved, Bode and other advocates say, the federal government needs more authority to override nasty squabbles between states, environmentalists, and other interest groups that have typically stalled such efforts. The federal government, the thinking goes, already has the authority to build natural gas pipelines across state lines, and electricity should be no different. That sentiment seems to be gaining ground even among regulators who once opposed it, although there are many issues still to be worked out. As Chu says, "If we just take the view that we are going to cram something down someone's throat, this is not a constructive way of doing business" (interview, Page 32). Infrastructure is only one part of the battle to make national energy problems a national issue. Another is technology. Even though wind power technology is relatively mature--it was the country's largest provider of clean electricity last year--most other renewable sources still need work. Improvements to photovoltaic cells could reduce solar power costs significantly. New drilling technologies could help geothermal spread across a larger geographic range. Advancements in befouls, in particular to the enzymes needed to break down grasses and woods to produce ethanol, would have a major impact. Meanwhile, fossil fuels face their own technological challenges. If coal is to stay around for a while, it'll most likely be because of still-developing methods to capture carbon dioxide emissions before they enter the atmosphere.Scientific breakthroughs don't come cheap. The economic stimulus package set aside $21.5 billion for scientific research, signaling that Washington is taking a much more active role in basic energy issues after years of declining budgets at national labs. But this is just the groundwork. The most powerful force to remake the energy America uses could be government policies: climate change legislation, which would set a price on carbon dioxide emissions, and a national renewable-electricity standard, which would require the United States to get a certain portion of its electricity from renewable energy. Both rules could have far-reaching impacts, forcing industries to massively reconsider their operations, giving financial investor’s confidence to pump money into wind farms, solar fields, and other industries, and convincing the coal industry that it's worth investing billions in technology to reduce emissions.The consequences of climate change legislation, in fact, are expected to be so great that companies typically opposed to government regulation are asking Congress to go ahead and act just so that they can have some certainty about where to put their money.What Washington won't do--not in theory, anyway--is pick specific winners. "The market will decide what the mix will be," says Matt Rogers, a former director at McKinsey & Co. and now one of Chu's top advisers. "It will be interesting to see what the market brings forward." Of course, in reality, Congress's record is one of subsidizing some industries but not others. Even within the befoul world, corn-based ethanol is heavily supported, but some others, such as befoul made from algae, receive almost no backing.In this new era of national energy, one of the primary questions facing the country is that of timing. When should things happen? And how soon can they occur? "Broadly, what scares me is that we want to do this in an incremental fashion. We want this to come across as painlessly as possible," say Rich Wells, vice president of energy at Dow Chemical. "We need a breakthrough mentality."It has become a cliché to say that there is no "silver bullet" for the nation's energy and climate problems. Most experts prefer to think about energy solutions as a collection of options to be deployed in tandem. Perhaps the most widely quoted example is the "wedge model," developed by Princeton University professors Stephen Pocola andRobert Soochow in 2004. It outlined 15 wedges, each one representing a way to significantly reduce greenhouse gas emissions over the next 50 years. Among them: raising the fuel economy of 2 billion cars from 30 mpg to 60 mpg and doubling nuclear capacity worldwide.Only some of these, of course, are realistic in the shorter term. "If you're only going to do one, the top one is always energy efficiency," says Dow's Wells. "It is for the most part the easiest, cheapest fuel out there." Amory Loins, chief scientist at the nonprofit Rocky Mountain Institute, agrees, saying that energy savings from highly fuel-efficient cars would be equivalent to "finding a Saudi Arabia under Detroit." Perhaps the biggest barrier for buildings has been the upfront cost of doing retrofits, with the need to convince people that the costs can be quickly recouped by lower energy bills. The stimulus package is taking a stab at this, setting aside $5 billion for home weatherization.Meanwhile, everyone else is jockeying for position. The befoul industry wants Congress to lift the cap on how much ethanol can be blended into gasoline. The nuclear industry is asking Congress to cough up billions to insure new nuclear power plants; wind and solar industries are asking for transmission superhighways. Detroit wants more in government bailout money. And coal wants money to research carbon capture technology. The great energy nationalization is here.译文:新能源经济每个国家都希望开发新能晕,但局限于开发的障碍以及技术问题。
