风能

(wind energy)

地球表面大量空气流动所产生的动能。由于地面各处受太阳辐照后气温变化不同和空气中水蒸气的含量不同，因而引起各地气压的差异，在水平方向高压空气向低压地区流动，即形成风。风能资源决定于风能密度和可利用的风能年累积小时数。风能密度是单位迎风面积可获得的风的功率，与风速的三次方和空气密度成正比关系。据估算，全世界的风能总量约1300亿千瓦，中国的风能总量约16亿千瓦。风能资源受地形的影响较大，世界风能资源多集中在沿海和开阔大陆的收缩地带，如美国的加利福尼亚州沿岸和北欧一些国家，中国的东南沿海、内蒙古、新疆和甘肃一带风能资源也很丰富。中国东南沿海及附近岛屿的风能密度可达300瓦／米2（W／m2）以上，3~20米／秒风速年累计超过6000小时 。内陆风能资源最好的区域 ，沿内蒙古至 新疆一带，风能密度也在200~300W／m2，3 ~20米／秒风速年累计5000~6000小时。这些地区适于发展风力发电和风力提水。新疆达坂城风力发电站1992年已装机5500千瓦，是中国最大的风力电站

在自然界中，风是一种可再生、无污染而且储量巨大的能源。随着全球气候变暖和能源危机，各国都在加紧对风力的开发和利用，尽量减少二氧化碳等温室气体的排放，保护我们赖以生存的地球。

风能的利用主要是以风能作动力和风力发电两种形式，其中又以风力发电为主，

以风能作动力，就是利用风来直接带动各种机械装置，如带动水泵提水等这种风力发动机的优点是：投资少、工效高、经济耐用。目前，世界上约有一白多万台风力提水机在运转。澳大利亚的许多牧场，都设有这种风力提水机。在很多风力资源丰富的国家，科学家们还利用风力发动机铡草、磨面和加工饲料等。

利用风力发电，以丹麦应用最早，而且使用较普遍。丹麦虽只有500多万人口，却是世界风能发电大国和发电风轮生产大国，世界10大风轮生产厂家有5家在丹麦，世界60%以上的风轮制造厂都在使用丹麦的技术，是名副其实的“风车大国”。

篇二：英语作文--翻译--风能

风是一种潜力很大的新能源。风能(wind energy)既清洁又可再生，所以越来越受到世界各国的重视。我国的风力资源极为丰富，绝大多数地区的平均风速都在每秒3米以上。早在20世纪70年代，中国就开始了发展风力发电(wing power)的努力。到2010年，中国风电装机容量(installed wind power capacity)超过美国，成为风力发电的第一大国。风力发电为保护环境做出了巨大的贡献。

The wind is a kind of new energy which possesses great

potential. Wind energy is clean and renewable, so more and more win the attention of the countries all over the world. Wind resource is very abundant in our country, the average wind

speed in most areas is more than three meters per second. In the early 1970 s, China commences efforts to exploit wind power. By 2010, since the installed wind power capacity more than the United States, China became the first power of wind power

generation. The wind power made a great contribution to protect the environment.

1. Fossil energy and nuclear energy are considered nonrenewable energy types. Nonrenewable

energy is obtained from sources at a rate that exceeds the rate at which the sources are replenished. For example, if the biogenic origin of fossil fuels is correct, we could consider fossil fuels renewable over a period of millions of years, but the existing store of fossil fuels is being

consumed over a period of centuries. Because we are consuming fossil fuels at a rate that exceeds the rate of replenishment, we consider fossil fuels nonrenewable. Similar comments apply to nuclear fuels such as uranium, as we observe in later chapters. Solar energy is considered a

renewable energy for the following reasons. Renewable energy is energy obtained from sources at a rate that is less than or equal to the rate at which the source is replenished. In the case of solar energy, we can use only the amount of energy provided by the sun. Because the remaining lifetime of the sun is measured in millions of years, many people consider solar energy an inexhaustible supply of energy. In fact, solar energy from the sun is finite, but should be available for use by many generations of people. Solar energy is therefore considered renewable. Energy sources that are associated with solar energy, such as wind and biomass, are also considered renewable. Solar radiation may be converted to other forms of energy by several conversion processes. Thermal conversion relies on the absorption of solar energy to heat a cool surface. Biological conversion of solar energy relies on photosynthesis. Photovoltaic conversion generates electrical power by the generation of an electrical current as a result of a quantum mechanical process. Wind power and ocean energy conversion rely on atmospheric pressure gradients and oceanic temperature

gradients to generate electrical power. In this chapter we focus on thermal conversion.We first discuss the source of available solar energy, and then consider solar energy technology in two of its three forms: passive solar, and active solar. The third form of solar energy, solar electric, is discussed in the next chapter. We end this chapter with a discussion of solar power plants.

2. There are many new energies for human beings nowadays. Such as nuclear energy, solar energy, wind power, ocean energy, etc. New forms of energy can greatly save traditional energies thus prevent our natural resources from being explored further. Solar energy, for example, is environment-friendly and has high efficiency. This feature is many traditional energies that unable to compare with. Moreover, new energies can be recycled for second uses, which is much better than traditional ones. Wind power is especially great because it could never be used up. So, we should take great advantage of new energies for our future development.

It has been known for some time now that a move towards sources of energy which are not carbon-based is urgently required to stop the effects of global warming. In my view, there are too few governments who seem to be promoting the use of other types of energy such as wind, wave, solar and nuclear sources of energy.

3. Governments at present are too reliant on coil, oil and gas. Although some governments are doing research into the use of alternative energy sources, many are not. Energy from the wind, the sea and the sun does not pollute the environment and is an everlasting source of power. Nuclear power is clean, and although it is not totally unproblematic, it would provide a large amount of energy and dramatically improve the environment. Countries such as France have made good use of nuclear power.

My feeling is that more use could be made of wind power. In some countries, there has been a reluctance to use wind turbines, even in areas which are not densely populated, as some people believe they are eyesores. Personally, I believe they are not only useful, but beautiful as well. Governments should spend more time and effort promoting the benefits of this source of energy and trying to make the public understand the reason for change.

In conclusion, I believe that, if governments forced everyone to have a wind turbine and solar panels on the building they live in, made more use of wave power and built more nuclear power stations, then they would manage to avert the dangers that are seriously threatening the Earth.

Wind Energy in China

Outlook for China’s Wind Power Development: Wind power will continue its rapid development in the coming decades, due to China’s commitment to energy efficiency and carbon dioxide emission reduction.

Chinese government promised to devote major resources to developing renewable and nuclear energy to ensure that by 2020, consumption of non–fossil fuel power will account for 15% of the country’s total primary energy consumption and the intensity of carbon dioxide emissions per unit of GDP will be reduced by 40–45% as compared with the emission level of 2005.

Preliminary analysis indicates that the contribution rate of wind power to the 15% goal is about 10%, which means wind power capacity must reach at least 150 GW by 2020.

This in turn means that in the years 2010–2020, the growth rate of wind power installed capacity will be kept at least at 14%, or 12 GW of annually added capacity. According to China’s 12th five-year plan, the generation of non–fossil fuel power will account for 11.4% of the country’s total primary energy consumption by 2015, instead of 8.2% as in 2005.

By 2015, there will be about 100 GW of wind power, which could displace the equivalent of 430 million tons of coal and reduce CO2 emissions by 1.2 billion tons annually, contributing 5% to achieving the emission reduction goal.

We believe that the experience and success of China in large-scale wind power development will be a valuable contribution to the development of global wind power utilization.

Wind and the environment

Wind energy is an economical power resource in many areas of the country. Wind is a clean fuel; wind farms produce no air or water pollution because no fuel is burned. The most serious environmental drawbacks to wind machines may be their negative effect on wild bird populations and the visual impact on the landscape.

篇五：风的描写,英文

Opening my eyes in the morning, I heard noise outside the window. After carefully listenin(转 载 于:wWW.smHAida.cOM 海达范文网:有关风能的英语作文)g, I found that it is the wind that screaming relentless and trying hard ceaselessly to crush into the warm room. I felt that I was to be blown away by the cold wind. It flapped me like a big fan and cut my face like a little knife. Because there were a mix of leaves and plastic bags circling in the air ahead of me, I had to care enough not to be stuck in that dirty eddy and went away as fast as I could. Though the sun had finally come out, the wind still refused to give in. It was determined to be the leading actor of that day, singing scrannel songs over and over again in falsetto. Looking around, you could notice that it was so powerful that it almost had kept everything under its control. Look! All the trees were swaying in its embrace. People’s clothes were flying higher and higher. The wind acted like a kid who was always entangling you in spite of your rejection. How naughty!
