英语70词风力发电作文
【篇一：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
风能汽车 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 cap
acity 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.
【篇二：关于风能的英语作文】
wind energy
  kinetic energy produced by earth surface large amount of air flow. the steam contents are different in diversity and air since the floor accepts sun irradiation queen air
temperature change everywhere, difference arousing everywhere pressure as a result, area flows to low pressure , is to form wind in high-handed air of level directio
n. wind energy source resource decides the yu feng neng density sum but the wind energy
source year making use of accumulates hour number. wind energy source density is
that the unit faces the wind covering an area of the groundless power gaining , the cube and air density direct proportion with wind speed concern. evidence is estimated, the whole world wind energy source all quantity about 130 billion kilowatt , chinese wind energy source all quantity about 1,600,000,000 kilowatt. wind energy source resource accepts the landform effect more, world wind energy source resource is many contraction zone focusing on littoral and open continent, inner mongolia , xinjiang and gansu province area wind energy source resource eich chinese southeast along the coast, also very much if american california composes in reply along the bank a few northern europe countries. littoral and neighbouring chinese southeast island and islet wind energy
source density may amount to 300 watts of/ rice 3 ~ 20 meters of/ second of wind speed year accumulative totals exceed 6000 hours above 2 (w／m2). best inner lu feng neng resource area, one takes along inner mongolia to xinjiang, wind energy source density also is in 6000 hours of 200 ~ 300 w／m2 , 3 ~ 20 meters of/ second of wind speed year accumulated 5000 ~. these area is suitable for developing wind pow
er generating
electricity preparing wind power carrying water. that xinjiang reaches the hill slope city wind power power station already packing machine in 1992 is a maximal chinese wind power power station 5,500,000 watts.
  the sources of energy the middle, wind in nature to be that one kind of regenerate , the nothing contaminate and reserves are gigantic. with the fact that the global climate is changed into the warm energy crisis,stepping up to the wind power exploitation and making use of in every country , cut down a carbon dioxide to the full waiting for
green-house gas emission , protect the earth on which we rely for existing. the wind
energy source making use of is two kinds forms mainly assume driving force with the wind energy source preparing wind power generating electricity , generate electricity among them with wind power give first place to,
  assume driving force with the wind energy source , be to make use of wind to come to set various mechanism in motion directly, waiting for this wind power engine merit if drive a water pump to carry water is: investment is few , work efficiency is tall , economy is
durable. at present, make an appointment with in the world having one baiduowan stage manner to mention water machine strenuously in turn over. many grazing land of aussie, set up have this wind power to mention water machine. in many countries of wind power
abound in natural resources, scientists making use of the wind power engine to chop fodder , grinding face and processing feed and so on.
  the application making use of wind power to generate electricity, with denmark is the earliest , usage is more common and. be that world wind energy source electric power generation great power and electric power generation wind wheel produce great power but though denmark only having more than 5,000,000 population,the ma
nufacturer world 10 gales wheels are produced has 5 being in denmark , the world 60% the above wind wheel manufactory technology all in using danish, is pinwheel great power  true to selfs name.
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500
0~6000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
