佛得角是塞内加尔沿海的一个群岛小岛屿发展中国家（SIDS），其政府制定了一个目标，即到2025年实现100%的可再生能源电力。群岛中的几个岛屿拥有合适的风能和太阳能资源，占全国电力输出的25%左右。然而，并非所有岛屿都同样拥有这些资源，岛屿之间缺乏电网连接对整合额外的可变能源发电构成了挑战。将海水淡化和储存（抽水蓄能或蓄电池）结合起来，可以使风能和太阳能的渗透率更高。海洋热能转换是一项新兴技术，可能适合佛得角。微电网和自我发电可能比大城市以外的电网连接更具成本效益。实现100%可再生能源的目标需要10亿美元的投资。佛得角拥有各种资源，可以帮助实现其100%可再生电力的目标，但以可管理和具有成本效益的方式将它们结合起来仍然是一个挑战。佛得角遇到的选择、机遇和挑战适用于其他国家，特别是世界各地的小岛屿发展中国家和群岛。
The government of Cape Verde, an archipelagic Small Island Developing State (SIDS) off the coast of Senegal, has established a goal to achieve 100% of its electricity from renewable sources by 2025. Several islands in the archipelago have suitable wind and solar resources and nationally these compose about 25% of the electricity output. However, not all islands are equally endowed with these resources and the lack of grid connections among islands poses challenges for integrating additional variable energy generation. Integrating desalination and storage (pumped hydro or battery) could enable greater penetration of wind and solar energy. Ocean thermal energy conversion (OTEC) is an emerging technology that could be suitable for Cape Verde. Microgrids and self-generation could prove to be more cost effective than grid connections outside of the large cities. Achieving the 100% renewable energy goal would require a US$1 billion investment. Cape Verde has a variety of resources that can contribute to achieving its 100% renewable electricity goal but combining them in manageable and cost-effective way remains a challenge. The options, opportunities, and challenges encountered by Cape Verde are applicable to other countries, especially small island developing states and archipelagos around the world.
