PUECO的可持續發展概論部落格

〔編譯管淑平／綜合報導〕風力發電向來被視為提供可再生能源，有助對抗全球暖化，不過，美國伊利諾大學一個研究團隊提出的一份新研究卻指出，風力發電其實會影響緊鄰電廠的周邊地區氣溫，白天較外圍地區冷、夜晚較暖，若規模夠大就足以造成區域性的氣候改變。

英國「每日郵報」5日報導，伊利諾大學大氣科學助理教授羅伊率領的團隊，針對加州聖戈岡尼奧風力發電廠做研究，發現風力發電機組後方區域，白天地表溫度比發電機組前方低，差距可達攝氏4度，夜間情況正好相反。
另一份由愛荷華州立大學進行的研究，支持羅伊的論點。該份研究發現，一塊有100台風力發電機的區域，當地地表溫度在夜裡較高，正好促進植物釋放二氧化碳的呼吸作用。羅伊研究團隊指出，目前這種效應只侷限於風力發電機組所在地區周邊。

在好奇心驅使下，找到一篇貼文（New findings about wind farms could lead to expanding their use）：http://news.illinois.edu/news/10/1005wind_farms.html

內容會比台灣版的完整許多.... 而且也點出作者本身在乎的結論：「We want to identify the best way to sustain an explosive growth in wind energy over the long term. Wind energy is likely to be a part of the solution to the atmospheric carbon dioxide and the global warming problem. By indentifying impacts and potential mitigation strategies, this study will contribute to the long-term sustainability of wind power」

台灣的媒體，摘錄新聞還真是會讓人捏把冷汗...

在好奇心驅使下，又找到一篇貼文（Could Windmills Alter the Weather?）：http://www.meteorologynews.com/2009/01/03/could-windmills-alter-the-weather/

讀者回文的部份還頗有趣的：「... The “weather” is a result of the earth’s atmosphere trying to correct energy imbalances (kinetic and latent) built up by differences in solar insolation over the earth’s surface. The sun and moisture are the drivers. The amount of energy in the atmosphere (again latent and kinetic) involved is huge (atomic bomb level of energy for a single supercell thunderstorm) compared to what is taken out by the wind turbines. And most of the energy in summer thunderstorms is driven by the release of latent heat from condensation in the storm, not the wind itself. So “stealing” some energy from the wind will have negligeable impact on the creation or sustainment of thunderstorms. Most changes would only noticeable on the micro-scale and will not impact the larger scale weather systems with any significance...」
