/write Rewrite the article in Chinese (Traditional). Add a paragraph that mentions that while putting solar panels on rooftop (residential, warehouse, commercial) is nice, they are much more expensive than solar farms on land and not necessarily suitable for all properties due to various reasons like orientation, structural support, planning permission etc.
英國太陽能電站擴展辯論中存在一個具有誤導性的關切:可用土地短缺的假想。關注糧食安全和鄉村保護的批評人士經常描繪大片太陽能陣列吞噬農業用地的景象,但實際數字講述了截然不同的故事。當與畜牧業、高爾夫球場和其他土地用途的實際占地面積進行對比時,太陽能發電所需的土地比例微乎其微。理解這種土地利用格局揭示了太陽能發展的限制主要源於政治和規劃因素,而非地理空間不足。[1]
目前,太陽能電站僅佔英國總土地面積的0.1%。儘管太陽能發電對國家電網的貢獻不斷增長,這個數字仍然非常微小。[1] 為達成英國政府的雄心勃勃目標——在2035年前安裝70吉瓦的太陽能容量——預測表明,太陽能基礎設施將佔據英國總土地面積的0.3%至0.6%,具體比例取決於所部署面板的效率和裝置密度。[1] [2] 為了讓這個數字更具說服力,即使英國將目前的太陽能存在量增加四倍,其占地面積仍將小於許多單個郡目前專用於高爾夫球場的土地。這種擴展絕不構成英國景觀的根本性轉變。
對比太陽能與畜牧業的土地需求時,差異變得尤為明顯。牛羊放牧地目前在英國占據超過1000萬公頃,代表所有土地的大約43%。[2] 這個龐大的占地面積遠遠超過任何合理的太陽能部署預估。在英國氣候條件下,單隻肉牛每年需要大約兩公頃的草地;羊群養殖雖然每隻動物對土地的需求相對較少,但仍然在高地和低地地區消耗大量土地。這種對比清楚地表明,對太陽能土地使用的擔憂在很大程度上被誇大了。
屋頂太陽能裝置——包括住宅、倉庫和商業物業上的安裝——在理論上是一個吸引人的替代方案。然而,屋頂太陽能裝置面臨許多實際困難,使其在實施上遠不如地面型太陽能電站可行。首先,成本因素至關重要:屋頂太陽能系統的安裝和維護成本遠高於大型地面太陽能電站,後者受益於規模經濟。其次,建築物的方位、屋頂傾斜角度和陰影等因素經常使許多房產不適合安裝太陽能面板。[1] 此外,屋頂結構承載力存在限制,不是所有建築都能支撐太陽能陣列的重量,改造其結構需要額外的投資和工程評估。最後,獲得規劃許可、建築條例批准和可能的列級房屋保護限制涉及複雜的行政程序,會延長項目時間表和增加成本。這些技術和官僚障礙使屋頂太陽能作為大規模能源轉型的主要解決方案不切實際,儘管它可以在特定情況下補充地面型太陽能部署。
地面型太陽能電站提供了顯著的成本優勢和規模經濟效益。這些大型裝置能夠以更低的每瓦成本生成電力,並且可以更有效地連接到電力傳輸網絡。農民和地主可以獲得長期租賃收入,同時在電站使用期間繼續對土地進行某些形式的管理。許多太陽能電站甚至支持野花通道和蜜蜂棲息地的創建,為環境保護做出貢獻。因此,英國太陽能發展的主要障礙並非來自於地理限制或土地稀缺性,而是來自於複雜的規劃程序、當地反對和政策不確定性。要加快英國邁向可再生能源的過渡,必須簡化審批程序,而不是無謂地擔憂不存在的土地危機。這種務實的方法將確保英國能夠有效地利用其豐富的太陽能資源,實現脫碳目標。
