臺灣各縣市的再生能源產生效率

近幾年溫室效應日漸嚴重，核能裝置安全等問題，使得再生能源的重要性越來越受到關注。本研究探討2013年至2017年，研究對象為臺灣本島各縣市及澎湖等18個縣市，再生能源產生效率之研究。採用資料包絡分析法 (DEA)的動態差額變數模型(DSBM)，模型中有四個投入項，分別為日照時數、總降雨量、風速和土地面積，三個產出項為太陽能發電量、風力發電量和水力及其他再生能源發電量和存在期間活動：再生能源裝置容量。研究結果顯示臺灣許多縣市的再生能源產生效率值極低，需要改善以提升效率；並採用分項效率算出太陽能、風力、水力和其他再生能源的發電效率，結果顯示：臺灣各縣市太陽發電效率皆表現良好，有設置風力發電地區除了新竹縣市皆表現良好，而水力和其他再生能源需改善效率的地區為高雄、屏東和臺東。最後將臺灣分為都市和非都市地區，並曼－惠特尼檢定，結果顯示：研究期間臺灣都市和非都市地區整體效率並無顯著的差異。在本論文的研究期間，臺灣各縣市的再生能源產生效率值逐年下滑。

In recent years, the greenhouse effect has been becoming increasingly serious, such that the importance of renewable energy more concerned. This study explores the research on the efficiency of renewable energy in 18 counties and cities of Taiwan's from 2013 to 2017. Using the Dynamic Slacks-Based Measure (DSBM) of Data Envelopment Analysis (DEA) and use disaggregated efficiency method. There are four inputs: Sunshine hours, total rainfall, wind speed, and land area. Three outputs include solar power, wind power, and hydropower as well as other renewable energy generations. The carry-over variable is the installed capacity of renewable energy. The results of the study show： The renewable energy generation efficiency scores in some Taiwan’s counties and cities are extremely low and need to be improved. The solar power generation efficiency of all counties and cities in Taiwan is generally high. The wind power generation efficiency is generally high except for Hsinchu City. The water power generation efficiency is generally high except for Kaohsiung, Pingtung, and Taitung. Regions in Taiwan are then divided into urban and non-urban areas. The Mann-Whitney test shows that there was no significant difference between urban and rural areas in the overall renewable energy efficiency of Taiwanese during the study period.
