新能源優點英語作文1
一、新能源汽車的優點:
1、環保,新能源汽車不采用燃油動力裝置,不需要柴油,汽油,而是清潔能源,比如電,太陽能,等,減少二氧化碳的排放。
2、不限號,在大城市新能源汽車是不限號的,更方便出行。
省燃油錢,如果使用燃油費大概6角到8角每公里,然而新能源只需要電費而已。
4、傳動效率高,新能源一般采用電機傳動效率高。
5、政策補貼,現在的新能源汽車享受政策補貼一輛車還能省不少錢。
二、新能源汽車的缺點:
1、汽車續航里程短,新能源汽車一般都是電動的,電池的蓄電量有限,持續行駛的里程也會受限
2、汽車售后服目前好不成熟,新能源汽車各方面都還在摸索、改善中,對于新能源汽車的售后維修,基本沒有很多熟練的維修人員,不能及時維修
3、汽車成本較高,電動車為了能反復充電和續航,必然需要好的電池,好的電機,成本相當高
4、汽車充電難、充電慢,新能源汽車應為受限于各方面的條件,還沒有完全普及,充電樁有限。
新能源優點英語作文2
新能源汽車的優點:
1、節約燃油能源。一般是用天然氣、石油氣、氫氣、電力作為動力。2、減少廢氣排放,有效的保護環境。電動汽車不產生尾氣,沒有污染。氫能源汽車尾氣是水,對環境沒有污染。因為基本屬于零排放,所以也在限號范圍外。3、效率高。一般新能源汽車采用新技術,新結構,使它的效率更高。4、噪聲低。新能源汽車缺點:1、因為新能源汽車處于起步階段,技術還不是很成熟。所以充電比較慢,需要數小時。2、車輛保有量低,充電、加氣、維修等不太方便。而且新能源汽車充電難,因為普及面小。3、續航里程短。一般車輛排量較小,動力不足,不適合長距離行駛。4、價格不低?,F在價格在5-10萬的新能源汽車,只有純電動汽車有批量生產,選擇性不是太大。
擴展資料:新能源汽車是指采用非常規的車用燃料作為動力來源(或使用常規的車用燃料、采用新型車載動力裝置),綜合車輛的動力控制和驅動方面的先進技術,形成的技術原理先進、具有新技術、新結構的汽車。新能源汽車包括純電動汽車、增程式電動汽車、混合動力汽車、燃料電池電動汽車、氫發動機汽車、其他新能源汽車等。
新能源汽車兩大階段:第一階段是以混合動力汽車為主,燃料電池車等新能源汽車為輔的發展方向,開拓新能源汽車市場。第二階段是在純電動汽車技術成熟的'基礎上,純電動汽車逐步替代混合動力及燃料電池汽車以至于完全占據新能源汽車市場,實現零排放的階段。中國新能源汽車產業始于21世紀初。2001年,新能源汽車研究項目被列入國家“十五”期間的“863”重大科技課題,并規劃了以汽油車為起點,向氫動力車目標挺進的戰略?!笆晃濉币詠?,我國提出“節能和新能源汽車”戰略,政府高度關注新能源汽車的研發和產業化。
新能源優點英語作文3
新能源汽車的優點一:環保
純電動汽車在運行過程中可以做到零污染,完全不排放污染大氣的有害氣體。即使按所耗電量換算為發電廠的排放,造成的污染也少于傳統汽車,因為發電廠的能量轉換率更高,而且集中排放可以更方便地假裝減排治污設備。
新能源汽車的優點 二:省錢
2014年,國家和地方政府給予電動汽車最高11.4萬元的補貼,這一舉措使電池成本居高不下的電動汽車的售價能夠下降到與傳統汽車相當的水平。而在油價高企的今天,電動汽車的運行費用是要遠小于傳統汽車的。
新能源汽車的優點 三:噪音小
電動機在運行中的噪音和振動水平都要遠遠小于傳統內燃機。在怠速和低速情況下,電動汽車的舒適性要遠高于傳統汽車,隨著速度的提升,胎噪和風噪成為噪音的主要來源,兩者才回到同一水平上。電動汽車的這一特點對于提升汽車的NVH性能無疑會有很大的幫助。
新能源汽車的優點 四:節能
電動汽車的百公里耗電量為15-20kwh,算上發電廠和電動機的損耗之后,百公里的能耗約為7公斤標準煤。傳統汽車按百公里耗油量10L計,能耗約為10公斤標準煤。并且在城市的擁堵環境里,電動汽車的節能優勢會進一步放大。
新能源汽車的缺點 一:充電難
在國內充電設施建設滯后的情況下,充電是電動汽車所面臨的的一大難題。公共場所充電樁的缺乏嚴重影響了電動汽車的出行。
新能源汽車的缺點 二:續航里程短
受限于電池的容量,目前大多數的純電動汽車續航里程都在100-200公里。雖然一再有專家說90%的人每日行駛距離不超過50公里,但是中國消費者對續航的要求比美國人更高,因為很少有中國家庭擁有超過1輛汽車,而美國人可以做到一輛純電動汽車通勤,一輛傳統汽車旅行。純電動汽車可以滿足老百姓平時上下班,但是周末外出,節假日出游的需求,又該如何解決呢?
新能源汽車的缺點 三:充電慢
目前大多數充電樁都是慢充樁,一輛車充滿需要5-8小時。雖然可以利用夜間休息時間充電,但是如果遇到什么突發情況,純電動汽車的充電慢的缺點就會凸顯無疑。
新能源汽車的缺點 四:售后服務有待加強
電動汽車結構雖然簡單,但是由于動力部分和傳統汽車相去甚遠,在維修起來還是會遇到一些麻煩。第一個問題就是維修技師的缺乏,現在絕大部分的技師能夠修傳統汽車,但是缺少電器方面的知識,貿然維修電動汽車不但可能造成車輛的損壞,還有一定的危險性。第二個問題是零部件的稀缺,電動汽車生產量和保有量都少,因此零部件少,價格還高。
以上就是由電動邦我給您分析得關于新能源電動汽車的四大優缺點 。 不知道是否對你們有所幫助,不過時代在更新,相信新能源電動汽車以后的發展肯定會越來越好,并且完善功能。

按以下要求寫一篇120詞的英語作文,1,電動汽車的開發受到政府重視 2,分析原因 3,
Developing Electric Cars
The electric car is an inspiring invention. Currently, the government is attaching more and more importance to the development of electric cars.
It is not hard for us to find the reasons why priority is given to electric cars. The primary reason, I think, lies in the fact that electric cars can save nonrenewable gasoline, which will somewhat lessen the pressure of energy crisis.
The second reason is that electric cars also contribute to environmental protection if we take into consideration the fact that they release no fumes.
Given that consumers are still in favor of cars powered by gasoline, the government should take measures to promote the development and use of electric cars.
The government can invest more money in the development of electric cars.
In addition, the publicity and education of environmental protection should be strengthened to enhance people's awareness of environmental protection.
重點詞匯:
more and more: 越來越...。
primary reason: 首要原因。
energy crisis: 能源危機。
contribute to: 捐助?;?給…投稿?;?捐給?;?投寄給。
environmental protection: 環境保護。
take into consideration:把…考慮進去?;?考慮到;顧及。
in favor of:有利于,交付給,以…為受益人?;?贊同,支持。

In this there is also some of the carbon trading mechanisms, such as emission reductions for developed countries to bear when the emission reduction targets by developing countries to reduce subsidies in developing countries to achieve the objective of reducing emissions. The emissions of six greenhouse gas emissions which, we believe that this which can make a reduction in the amount of calculation, the total of the plate in the inside, the United States decreased by 30 million tonnes of emissions, then how such emission reductions it ? An energy efficient way, such as building energy accounted for 40% to 50%, the cost is relatively low, transportation accounted for 20% to 30% more money another way
Such as investment in new energy vehicles, this car is more expensive, the cheapest way is to segment solar, we have the economic effect of speaking, solar energy is the most economical, then the amount of building is the largest.
Low-carbon economic revolution fourth birth, the first economic revolution was the steam engine, the second industrial revolution is the power, the third is the information revolution, this time in a new energy revolution, to prevent the depletion of renewable energy to prevent global warming, action to save the planet.
Now countries are increasing the proportion of new energy sources, this is the year 2020 20% of transportation energy, is in change, energy consumption is also changing. New energy revolution, the top place is a power aspects, such as the United States standards, the United States in 2020 is 25%, Britain 30%, China's target is very ambitious, we feel that in the traditional economy which has reached a limit, the urban population is now an average of 200 million tons per steel, when the largest output in the United States is so great,
So from now we look at iron and steel production capacity is already a surplus, but in its development of new energy, the speed is very large, such as solar, we basically from scratch, wind energy's growth is very fast, these industries We believe that high growth companies, you save up the economy beyond the traditional to the inventory of another problem, but the new energy economy, then it is a very great demand.
Current solar energy market is from Spain and Germany, led the two small countries, with the United States, China, Japan to subsidize solar energy after the beginning, we believe that the largest solar market after should be in there among the three countries, solar energy is scratch, we feel that its space is very huge.
Wind power, then China's generating capacity is 800 million million, the current wind power is the closest to the cost of thermal power reached 0.4 to 0.6 yuan, we have now is the world's fourth largest wind power installed capacity of the country, the pace of growth is very fast , is expected to soon be able to surpass the U.S. as the world's first wind-power generators States.
If nuclear power, France, Korea, Japan, the very fast development in this industry, our development of space will be very great. Network connection, because the load during the day and night is not the same load, so there is a process of division-type online, interactive generation, then electricity before you, but since you installed solar panels at home, you to generate electricity, you can also sell power grid, which is an interactive situation.
New energy power generation of the most important change is the new energy vehicles, because the automotive industry worldwide 800 million, this year we China has surpassed the U.S. as the automotive consumer, that rate continues, this energy are not enough, so the faster development of this industry, then, so we need new energy vehicles to solve this problem, you have to buy a car, car and resource constraints of the conflict, it is necessary to solve the new energy vehicles. For the old economy, the status of a recession, but if the new economy, its development and space are very large.
Now the new energy vehicle is divided into three growth levels, a car, battery, battery materials there, this regard, we believe that a revolution will happen, now the core of the new energy industry is the battery, wind power to energy storage, nucleus is unstable, this network also need batteries, battery energy storage is the new tool is called the fourth meeting of the Industrial Revolution.中文翻譯是在這個里面還有一些碳交易的機制,比如發達國家在承擔減排量的時候,可以通過發展中國家的減排指標來達到減少資助發展中國家的減少排放的目的。這個排放里面六種溫室氣體的排放,我們認為這個里面可以做出一個減排的量的測算,在這個總的盤子里面,美國減少30億噸的排放量的話,這種減排怎么減排呢?一種節能的方式,比如建筑物節能占了40%~50%,成本是比較低的,交通運輸占了20%~30%,另外一個比較花錢的方式,比如投資新能源汽車,這種汽車是比較貴的,最便宜的方式是分部式太陽能,我們從經濟效果來講,太陽能是最經濟的,那么建筑物的量是最大的。低碳催生第四次經濟革命,第一次經濟革命是蒸汽機,第二次產業革命是電力,第三次是信息革命,那么這一次又是新能源革命,防止再生能源的枯竭,防止地球變暖,拯救地球的行動?,F在各個國家正在提高新能源的比例,這個都是在2020年之前達到20%左右,能源的運輸方式也是在發生變化,能源消費方式也是發生變化。新能源革命發生最上面的是一個電源方面的情況,比如美國的標準,到2020年美國是25%,英國是30%,中國的目標也是非常宏大的,大家覺得在傳統的經濟里面已經達到了一個極限,現在城市人口平均每個人平均兩億噸的鋼,在美國產量最大的時候也就是這么大,所以從現在來看我們鋼鐵的產能已經是過剩的了,但是在新能源方面它的發展速度是非常大的,比如太陽能我們基本上是從零起步,風能的增速也是非??斓?,這些行業我們認為是高成長的企業,你就傳統的經濟救起來以后還有一個去庫存化的問題,但是新能源經濟的話,它的需求是非常大的。目前太陽能的市場是由西班牙和德國這兩個小國家在主導,隨著美國、中國、日本對太陽能開始補貼以后,我們認為太陽能以后的最大的市場應該會在這三個國家當中出現,太陽能是零起步,我們覺得它的空間是非常巨大的。風電的話,中國的發電容量是8億千萬,目前風電是最接近火電成本的,達到0.4到0.6元,我們現在已經是全球第四大的風電裝機國,成長的速度也是非??斓?,預計很快可以超過美國,成為世界第一大風電裝機國。核電的話,法國、韓國、日本發展的非???,在這個行業,我們的發展空間也會非常的巨大。電網方面,因為現在白天的負荷和晚上的負荷是不一樣的,這樣就有一個分部式上網的過程,交互式發電的話,以前你是用電的,但是以后你家里裝了太陽能面板,你可以發電,還可以賣給電網,這就是一個交互式的情況。新能源發電最重要的變革就是新能源汽車,因為汽車行業在全球有8億部,今年我們中國已經超過美國,成為汽車消費大國,如果按照這個速度發展下去,這個能源是不夠用的了,所以這個行業發展越快的話,所以就需要新能源的汽車來解決這個問題,你要買車、用車和資源約束的矛盾,所以必須要解決新能源汽車。對于舊經濟而言,是一個衰退的狀況,但是對于新經濟的話,它的發展和空間都是非常大的?,F在的新能源汽車分為三個增長層次,有汽車、動力電池,還有動力電池材料,這個方面我們認為會發生一場革命,現在新能源產業的核心就是這個電池,風電必須儲能,核點不穩定,電網也是這樣需要電池,電池是各種新能源儲能的工具,所以被稱為第四次工業革命。
