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。
求一篇“新能源汽車”的英語作文
Environmental protection everybody has a responsibility
Now, the pollution already has become the globalization question. The air, Haihe river, the soil pollution extremely is all harmful to the humanity and the zoology and botany
For example, because present automobile more and more many, therefore the waste gas discharges also day by day increases, as the matter stands our air is polluted extremely seriously, this is extremely harmful to our health. Also, the water source under ours destruction, the pollution extremely is also serious, again like this gets down our humanity to be able to perish.
For our humanity, therefore we must adopt the effective action antipollution, the purification environment, protects the ecological equilibrium. For example, we may the afforestation prevent soil erosion. We may develop the new energy and so on. Environmental protection everybody has a responsibility.

Advantages and Disadvantages of EVs
The most obvious advantage of electric car batteries is that they don't produce the pollution associated with internal combustion engines. However, they still have environmental costs. The electricity used to recharge EV batteries has to come from somewhere, and right now, most electricity is generated by burning fossil fuels. Of course, this produces pollution. But how does the pollution produced by burning fossil fuels to recharge electric car batteries compare to the pollution produced by internal combustion engines? According to the Electric Vehicle Association of Canada, or EVAC, even EVs recharged from coal-powered electric generators cut carbon emission roughly in half. EVs recharged from cleaner forms of electrical power generation, such as hydropower and nuclear plants, can reduce carbon emissions to less than one percent of those currently produced by internal combustion engines. So, even in the worst case scenario, cars operated by EV batteries are cleaner than gas-powered cars.
Another important advantage of battery-powered motors over gas-powered engines is the lower cost of the fuel -- that is, electricity for EVs and gas for the internal combustion engines. The United States Department of Energy has calculated that a typical EV can run for 43 miles on a dollar's worth of electricity. Only a substantial drop in the cost of gasoline could give gas-powered cars anywhere near such a low cost per mile.
Yet another advantage of these rechargeable batteries is that they recycle well. Almost 100 percent of these batteries can be recycled, which keeps old batteries from becoming a disposal problem.
The major disadvantage of battery-powered cars, as we mentioned in the last section, is the time required to recharge the batteries. With lithium-ion battery technology, a fully charged EV can travel a distance comparable to an internal combustion engine vehicle with a full tank of gas, but it still needs to be placed on a recharger at the end of that time. At present, this means a drained EV will be out of service for several hours before it's fully recharged. Of course, this is a serious disadvantage. In the future, faster recharging technology may become available, but in the near term, electric cars won't be the vehicles of choice for long trips. Even so, most driving is done relatively close to home and for this reason, battery power will serve as well as gasoline power. A possible solution to the recharging situation may be battery-replacement stations, where instead of recharging your EV you can simply swap your drained battery for a fully charged one. This system would allow batteries to be recharged outside of vehicles and would greatly reduce the amount of time required to get an EV up and running again after its battery is fully discharged.
Another disadvantage of electric car batteries is their weight. Because they need to do more than traditional car batteries, electric car batteries need to be linked together into arrays, or battery packs, to provide additional power. These collections of batteries are heavy. The lithium-ion battery pack in a Tesla Roadster weighs about 1,000 pounds (453.6 kg). That's a lot of weight to carry and it can greatly reduce the car's range. However, the designers of the Roadster have offset this battery weight with a light frame and body panels. The entire car only weighs 2,690 pounds (1220.2 kg) -- not terribly heavy when you consider that more than a third of that weight is battery.
Given the importance of the battery to an electric car, you might wonder what will happen as that battery grows older. How long will it be able to power the car? And when it finally dies, can it be replaced or is it simply more economical to buy a new car? Read on to find out.
