2007年綠島鄉居民約3,026人，觀光客為335,380人次。在用電需求方面，2007年綠島鄉用電度數約12MWh，綠島發電廠預計在2009年更新2部柴油發電機，提供綠島地區足夠的電力，但也將加劇台電公司離島營運虧損，並且造成嚴重的環境污染。因此本研究規劃2010年，設置5.75%再生能源，包括微渦輪機組、太陽能、風力、風光互補。2020年擴大規模，達到再生能源比例32.93%的目標。
廢棄物處理方面，2007年綠島鄉清運2,462公噸廢棄物，送往衛生掩埋場處理，當地資源回收商收集524公噸資源回收物品，以船運至台東富岡漁港。觀光遊客是綠島地區垃圾主要產生源，因此鼓勵遊客減用一次即丟物品、落實垃圾分類資源回收，並且協助離島資源回收商積極收取資源物品，是綠島廢棄物處理最重要工作。

Abstract
Green Island is situated at the South-East side of Taiwan. It covers 15km2 of land with population of 3,026 habitants. With its multiform ecological environment, there are almost 340 thousand tourists. Residents and travelers consume 12MWh electricity in 2007. Under the huge pressure of power demand, the local power plant in Green Island proposes to add two diesel fuel generators. Burning diesel fuel could harm natural resource in Green Island and cause the local power plant’s pecuniary loss by the government electricity subsidy scheme. Therefore it is very important to reduce the reliance on fossil fuel and utilize renewable energy source in Green Island. This research shows two stage of practicable renewable energy plan. By 2010. It will ultimately result in 5.75% of installed capacity being delivered from renewable energy, including a combination of solor power system, wind turbine, wind-PV hybrid power, and micro turbine generator sets. About 32.93% of island electricity needs will be met with renewable energy on 2020.
In terms of waste treatment in Green Island, approximately 2,462 ton municipal solid waste is collected from habitants and tourists by local goverment in 2007. The municipal waste is disposed in sanitary landfill near Haisenping in Green Island. Besides, there are 524 ton recyclables collected by local recycling companies in Green Island and transpoted to Fugang Fishery Harbor in Taitung. The amount of waste and recyclables goes up quite substantially as a result of a large number of tourists staying in Green Island. For this reason, recycling operation to be put into effect by tourists and recyclables collection to be carried out by local recycling companies are significant works for local government in Green Island.
