Energy security on islands is a challenging issue due to their isolation from energy markets and fossil fuel dependence. In addition, islands’ average energy intensity has increased in recent years due to economic development. This research explores the environmental performance of two alternative non-variable bioelectricity feedstocks to increase energy resilience on islands. The study was developed for the Galápagos islands to address the environmental impacts from the direct use of waste cooking oil (WCO) and refined palm oil (RPO) to produce 1 MWh using the life cycle assessment methodological framework. A combination of primary and secondary data sources was used. The results show better performance for the electricity derived from WCO in all the impact categories considered when compared to RPO.

岛屿上的生物能源：大陆棕榈油与当地发电用废食用油的环境比较

由于岛屿与能源市场隔离和对化石燃料的依赖，岛屿上的能源安全是一个具有挑战性的问题。此外，由于经济发展，近年来岛屿的平均能源强度有所增加。这项研究探索了两种替代性不变式生物电原料的环境性能，以提高岛屿的能源弹性。该研究是针对加拉帕戈斯群岛开发的，旨在解决使用生命周期评估方法框架直接使用废烹饪油（WCO）和精炼棕榈油（RPO）产生1 MWh的环境影响。使用了主要和辅助数据源的组合。结果显示，与RPO相比，在所有考虑的影响类别中，来自WCO的电力的性能都更好。
