風能
(wind energy)
地球表面大量空氣流動所產生的動能。由於地面各處受太陽輻照後氣溫變化不同和空氣中水蒸氣的含量不同,因而引起各地氣壓的差異,在水平方向高壓空氣向低壓地區流動,即形成風。風能資源決定於風能密度和可利用的風能年累積小時數。風能密度是單位迎風面積可獲得的風的功率,與風速的三次方和空氣密度成正比關系。據估算,全世界的風能總量約1300億千瓦,中國的風能總量約16億千瓦。風能資源受地形的影響較大,世界風能資源多集中在沿海和開闊大陸的收縮地帶,如美國的加利福尼亞州沿岸和北歐一些國家,中國的東南沿海、內蒙古、新疆和甘肅一帶風能資源也很豐富。中國東南沿海及附近島嶼的風能密度可達300瓦/米2(W/m2)以上,3~20米/秒風速年累計超過6000小時 。內陸風能資源最好的區域 ,沿內蒙古至 新疆一帶,風能密度也在200~300W/m2,3 ~20米/秒風速年累計5000~6000小時。這些地區適於發展風力發電和風力提水。新疆達坂城風力發電站1992年已裝機5500千瓦,是中國最大的風力電站
在自然界中,風是一種可再生、無污染而且儲量巨大的能源。隨著全球氣候變暖和能源危機,各國都在加緊對風力的開發和利用,盡量減少二氧化碳等溫室氣體的排放,保護我們賴以生存的地球。
風能的利用主要是以風能作動力和風力發電兩種形式,其中又以風力發電為主,
以風能作動力,就是利用風來直接帶動各種機械裝置,如帶動水泵提水等這種風力發動機的優點是:投資少、工效高、經濟耐用。目前,世界上約有一白多萬台風力提水機在運轉。澳大利亞的許多牧場,都設有這種風力提水機。在很多風力資源豐富的國家,科學家們還利用風力發動機鍘草、磨面和加工飼料等。
利用風力發電,以丹麥應用最早,而且使用較普遍。丹麥雖只有500多萬人口,卻是世界風能發電大國和發電風輪生產大國,世界10大風輪生產廠家有5家在丹麥,世界60%以上的風輪製造廠都在使用丹麥的技術,是名副其實的「風車大國」。
wind energy
Kinetic energy proced 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 direction. 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 enrich 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 power 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 rable. At present, make an appointment with in the world having one Baiowan 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 proce Great Power but though Denmark only having more than 5,000,000 population,the manufacturer world 10 gales wheels are proced has 5 being in Denmark , the world 60% the above wind wheel manufactory technology all in using Danish, is "pinwheel Great Power " true to self's name.
② 有關風力發電或太陽能發電文章的英文
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.1
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.
③ 風能發電的歷史英語作文
風很早就被人們利用--主要是通過風車來抽水、磨面……。人們感興趣的,首先是如何利用風來發電。風是一種潛力很大的新能源,人們也許還記得,十八世紀初,橫掃英法兩國的一次狂暴大風,吹毀了四百座風力磨坊、八百座房屋、一百座教堂、四百多條帆船,並有數千人受到傷害,二十五萬株大樹連根拔起。僅就拔樹一事而論,風在數秒鍾內就發出了一千萬馬力(即750萬千瓦;一馬力等於0.75千瓦)的功率!有人估計過,地球上可用來發電的風力資源約有100億千瓦,幾乎是全世界水力發電量的10倍。全世界每年燃燒煤所獲得的能量,只有風力在一年內所提供能量的三分之一。因此,國內外都很重視利用風力來發電,開發新能源。
The wind was used by people for a long time-mainly through windmills to pump water and grind the surface... People are interested in how to use wind to generate electricity.
Wind is a new energy source with great potential. People may still remember that in the early eighteenth century, a violent wind swept across Britain and France destroyed 400 wind mills, 800 houses, 100 churches, and 4 More than a hundred sailing ships, thousands of people were injured, 250,000 big trees were uprooted. As far as pulling trees is concerned, the wind can emit 10 million horsepower (that is, 7.5 million kilowatts; one horsepower is equal to 0.75 kilowatts) in a few seconds! Someone has estimated that the amount of wind resources available for power generation on the earth is about There are 10 billion kilowatts, almost 10 times the world's hydroelectric power generation. The energy obtained by burning coal every year in the world is only one third of the energy provided by wind power in a year. Theref
