Spanish Solar Energy
西班牙太陽能


The sun-drenched swaths of land in southwestern Spain seem custom-made for large solar
projects. Add generous government subsidies to this hospitable climate, and the solar
opportunity in regions like Andalusia and Extremadura would seem almost too good to be
true.
在陽光普照的西班牙南部使用大型的太陽能計畫，當地政府投以大量的資金，
而在安達魯西亞和埃斯特雷馬杜拉有這樣的機會真是再好不過了！

In fact, it was too good to last.
事實上，這真是好極了。

In the wake of an overheated solar market and the global financial crisis, Spain has slashed
its renewable energy subsidies.And the solar boom under the Mediterranean sun has gone
bust a stunning reversal of fortune: In 2008, 40 percent of the world's solar installations
were in Spain.
在過熱的太陽能能源市場以及全球金融危機，西班牙政府已經削減了可再生能
源的補貼，在地中海的陽光照耀之下，太陽能能源的熱潮已經產生一個驚人的
逆轉，在2008年，全球40%的太陽能裝置已集中在西班牙。

But it's hardly the end of the road for the technologies nurtured on the Iberian peninsula.
Spanish companies are working to export their know-how to the United States, Latin
America and even to other European Union nations.
但是在伊比利亞半島，這個技術是比較難達成的。西班牙的企業家們正在努力
推廣其效用到美國、南美洲 、甚至歐盟國家。

Although the United States developed experimental solar power towers in the Mojave
Desert in the wake of the 1970s energy crisis, it was nearly three decades later that Spain
put the world's first commercial solar tower online in March 2007, 15 miles west of
Seville in southern Spain's Sanlúcar la Mayor. The Planta Solar 10 solar tower plant, seen
above with sunlight glinting at the top of its 377-foot (115-meter) tower, can provide
electricity for as many as 5,500 homes and store energy for up to 30 minutes.

雖然美國在20世紀的70年代的能源危機之後就在莫哈韋沙漠建立了一座實驗性
的太陽能發電塔，在將近三十年之後，2007年3月，西班牙才建立了全球第一座
商業性太陽能塔，從西賽維利亞蔓延25公里至西班牙南部的聖路卡馬。
在The Planta Solar 10的太陽能計畫中，在其115公尺高的塔頂可看到太陽光閃閃發
亮，可為5,500多個家庭提供電力，並可儲存約30分鐘的電量。

Like all concentrating solar plants, power towers use steam turbines to drive a generator to
produce electricity.But developers long believed using circular rows of mirrors to focus the
sun's rays on a central  "power tower"would be more efficient than other types of reflector
arrays, and would make it easier to integrate technology to store energy.
像所有的聚光太陽能廠，電力鐵塔使用汽輪機驅動發電產生電力。但使用環形
的鏡子排列在太陽能塔周圍，讓太陽光集中在中央的太陽能電力塔，會比其他
方式的排列反射鏡更有效率，也更容易整合電量。

From a distance, the result is an otherworldly scene akin to a high-tech crop circle or an
alien amphitheater. Up close, the projects resemble fields of giant mechanical sunflowers
craning their shiny faces toward a glowing tower.
從遠處看，太陽能塔周圍看起來就像是一個高科技麥田圈，也像是一個新型的
露天劇場。太陽能塔周圍也種植了一些向日葵，向日葵因為向光性所以都向著
太陽能塔生長。

Towering Technology for Solar
高聳的太陽能技術


Planta Solar 20, or PS20, is a 20-megawatt solar power tower plant built alongside PS10
in Sanlúcar la Mayor.Completed in April 2009 and supported by 1.9 million euros
($2.5 million) in incentives from the Andalusian Regional Government, PS20 has capacity
to generate more than 40 gigawatt-hours of energy annually—enough to supply power for
10,000 homes.
Planta Solar 20 或 PS20 是一個在聖路卡馬的一個20兆瓦的太陽能發電塔，從
2009年的四月開始，當地地區政府鼓勵完成太陽能能源裝置之後，PS20每
年可生產40千兆瓦的能源，足以供電給10,000個家庭。


The plant uses 1,255 mirrors positioned across 210 acres to concentrate sunlight on a
receiver mounted on the central tower. Water pumped up the 160-meter (541-foot)
structure and through the receiver boils into steam. This steam is used to turn a turbine
to produce electricity.
此太陽能源廠使用了1,255片鏡子，橫跨了210英畝，再將能源塔安裝在中央
接收太陽光。塔中的渦輪可將水抽到160米，並將水沸騰使之變為蒸汽，這
種蒸汽用來使渦輪機產生電力。

And Abengoa is exporting its technology. Late last year, the Spanish company secured
a $1.2 billion loan guarantee  from the U.S. Department of Energy for a solar plant in
southern California using  its parabolic trough technology.
阿文戈亞集團目前出口這項太陽能能源，去年年底，這家西班牙公司利用
拋物線槽技術在南美洲太陽能廠獲得美國能源署12億的貸款擔保。
