太陽能發(fā)電很大程度上取決于補貼。面對緊縮時代，國家的政府表示將縮減補貼拯救歐元區(qū)成員國。西班牙太陽能產(chǎn)業(yè)危機重重。
   西班牙的問題不只四面楚歌德政府將減少對新項目的補貼。更嚴重的恐慌在于，政府將削減已商定建設項目或正在建設項目的補貼。補貼削減的不確定性已在陽光普照的西班牙景觀投下陰影。
   發(fā)生危機時，太陽能發(fā)電的補貼是在容易下手的目標。西班牙的光伏部門的支出激增是另一驅(qū)動，2002年以來投資230億?。為所有可再生能源的補貼年費用去年高達50億??衲暝蚩紗鋃3億?＜BR>  太陽能電池板價格下降，而一些新興工廠利潤飆升，這不利于整個行業(yè)的發(fā)展。調(diào)查人員表示，風能，太陽能發(fā)電機生產(chǎn)商注冊要求更高的補貼。 西班牙應該避免拋出骯臟的洗澡水與襁褓中的可再生能源。 Thermosolar能源被視為比散裝的光伏電池陣列發(fā)電更具有競爭力。風能推廣已經(jīng)取得成功，減少了西班牙的能源進口費用，削減了二氧化碳排放量，并鼓勵了具有國際競爭力的能源公司的增長。
  通過補貼支持可再生能源不一定不好。但西班牙的經(jīng)驗表明，它需要更多的遠見和更好的成本和效益進行評估。
  The problem is not just that the embattled Spanish government will reduce subsidies for new projects. More serious is the fear that the government will cut agreed subsidies for projects built or under construction.

  Unfortunately for the industry, solar power subsidies are an easy target in times of crisis. There was a surge of subsidy-driven spending in Spain’s photovoltaic sector, with ?3bn invested since 2002 ? a quarter of that in 2008 alone. The annual cost of subsidies for all renewables reached ?bn last year and could hit ?.3bn this year.

  Still, Spain should avoid throwing out the renewable energy baby with the dirty bathwater. Thermosolar energy is regarded as a more competitive source of bulk electricity than arrays of photovoltaic cells. And the promotion of wind energy, in spite of occasional abuses, has been a success, reducing Spain’s energy import bill, cutting its carbon dioxide emissions and encouraging the growth of internationally competitive energy companies.

  Supporting renewable energy through subsidies is not necessarily foolish. But Spain’s experience shows that it needs to be done with more forethought and a better assessment of costs and benefits.
