Development of new energy should be established as an important strategy for China to address energy shortage and environmental woes, Zhang Guobao, head of the National Energy Administration, said Saturday.

To develop new sources of energy has become an important strategy for many countries to fight for a dominance in the combat against climate change, and China should closely follow global developments in this area, beef up RD of new energy technologies, and invest more in the industry, said Zhang.

"If we fail to address the development of new energy from a higher horizon, we will regret to find ourselves falling behind others within 10 years," said Zhang, a member of the National Committee of the Chinese Peoples Political Consultative Conference (CPPCC).

Zhangs advocation is echoed by Ouyang Minggao, who underlined the use of new-energy vehicles at the same plenary meeting of the top political advisory body.

"The promotion of energy-efficient and new-energy vehicles is a necessary step in the countrys energy development and in the revival of the auto industry," said Ouyang, a Tsinghua University professor.

In China, coal makes up about 70 percent of its total energy consumption, 40 percentage points higher than the world average.

The country is seeking the development of other energy sources than coal to shift its heavy reliance on coal and reduce pollution.

Premier Wen Jiabao said in the government work report delivered to lawmakers Thursday that the country will "energetically develop a circular economy and clean energy."

The country would promote RD on technologies in new energy sources and develop clean energy such as nuclear, wind, and solar power this year, according to Wens report.

Yang Qi, honorary president of the Nuclear Power Institute of China and a CPPCC National Committee member, urged the country to develop new technologies to conserve energy and reduce emissions.

He said the country is stressed by targets to improve energy efficiency and reduce emissions, as the country is expected to initiate more projects under the huge 4-trillion-yuan stimulus plan.

Premier Wen said Thursday the countrys energy consumption per unit of GDP fell by 4.59 percent from the previous year, chemical oxygen demand down by 4.42 percent, and sulfur dioxide emissions down by 5.95 percent.

Over the past three years, total energy consumption per unit of GDP dropped by 10.08 percent, chemical oxygen demand down by 6.61 percent, and sulfur dioxide emissions down by 8.95 percent, according to the Premier.

China aims to cut energy consumption for every 10,000 yuan (1,298 U.S. dollars) of GDP by 20 percent from 2006 to 2010, with emissions to drop 10 percent.

Various forms of new energy is the heat energy directly or indirectly from inside the sun or the earth out of the generated. Solar energy, wind energy, biomass energy, including hydropower,geothermal energy and ocean energy, as well as derived from renewable energy, bio fuels and hydrogen generated energy.

Characteristics of two, new energy:

New energy including a variety of renewable energy and nuclear energy. Compared to conventional energy sources, new energy generally has the characteristics of less pollution,large reserves, to solve the serious problem of environmental pollution and resources(especially fossil energy) depletion problem has important significance. At the same time,because the new energy distribution, to solve the energy caused by the war has important significance.

According to the world the assertion, oil, coal and other resources will accelerate the reduction. Nuclear energy, solar energy will become the main energy.

Three, you mentioned two kinds of new energy introduction:

1, solar energy

Generally refers to solar radiation energy of the sun light. The main use of solar energy in the form of a poelectric conversion of solar energy pothermal conversion, and conversion of three kinds of main ways of pochemistry

Generalized on solar energy on earth is a lot of energy sources, such as wind energy,chemical energy, potential energy of water causes or transformed into by solar energy form.

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.

新能源优点英语作文3

新能源汽车的优点一:环保

纯电动汽车在运行过程中可以做到零污染,完全不排放污染大气的有害气体。即使按所耗电量换算为发电厂的排放,造成的污染也少于传统汽车,因为发电厂的能量转换率更高,而且集中排放可以更方便地假装减排治污设备。

新能源汽车的优点 二:省钱

2014年,国家和地方政府给予电动汽车最高11.4万元的补贴,这一举措使电池成本居高不下的电动汽车的售价能够下降到与传统汽车相当的水平。而在油价高企的今天,电动汽车的运行费用是要远小于传统汽车的。

新能源汽车的优点 三:噪音小

电动机在运行中的噪音和振动水平都要远远小于传统内燃机。在怠速和低速情况下,电动汽车的舒适性要远高于传统汽车,随着速度的提升,胎噪和风噪成为噪音的主要来源,两者才回到同一水平上。电动汽车的这一特点对于提升汽车的NVH性能无疑会有很大的帮助。

新能源汽车的优点 四:节能

电动汽车的百公里耗电量为15-20kwh,算上发电厂和电动机的损耗之后,百公里的能耗约为7公斤标准煤。传统汽车按百公里耗油量10L计,能耗约为10公斤标准煤。并且在城市的拥堵环境里,电动汽车的节能优势会进一步放大。

新能源汽车的缺点 一:充电难

在国内充电设施建设滞后的情况下,充电是电动汽车所面临的的一大难题。公共场所充电桩的缺乏严重影响了电动汽车的出行。

新能源汽车的缺点 二:续航里程短

受限于电池的容量,目前大多数的纯电动汽车续航里程都在100-200公里。虽然一再有专家说90%的人每日行驶距离不超过50公里,但是中国消费者对续航的要求比美国人更高,因为很少有中国家庭拥有超过1辆汽车,而美国人可以做到一辆纯电动汽车通勤,一辆传统汽车旅行。纯电动汽车可以满足老百姓平时上下班,但是周末外出,节假日出游的需求,又该如何解决呢?

新能源汽车的缺点 三:充电慢

目前大多数充电桩都是慢充桩,一辆车充满需要5-8小时。虽然可以利用夜间休息时间充电,但是如果遇到什么突发情况,纯电动汽车的充电慢的缺点就会凸显无疑。

新能源汽车的缺点 四:售后服务有待加强

电动汽车结构虽然简单,但是由于动力部分和传统汽车相去甚远,在维修起来还是会遇到一些麻烦。第一个问题就是维修技师的缺乏,现在绝大部分的技师能够修传统汽车,但是缺少电器方面的知识,贸然维修电动汽车不但可能造成车辆的损坏,还有一定的危险性。第二个问题是零部件的稀缺,电动汽车生产量和保有量都少,因此零部件少,价格还高。

以上就是由电动邦我给您分析得关于新能源电动汽车的四大优缺点 。 不知道是否对你们有所帮助,不过时代在更新,相信新能源电动汽车以后的发展肯定会越来越好,并且完善功能。
