Millions of dollars have been spent on island nations to help them select, analyze, and finance cost-effective energy solutions. Millions more are earmarked to ensure these systems are compatible with combating climate change. The results of this process demonstrate that comprehensive planning combined with projects to capture the opportunity are a more powerful approach to helping islands transition their energy systems than projects alone. The approach can be scaled to many island nations with the support of the donor community and a willingness of those engaged in the process to create national energy strategies that will benefit these islands for years to come. Lastly, the process provides guidance to aid agencies, project developers, and efficiency companies, allowing them to put their efforts to best effect.
