This paper seeks to explore a comprehensive set of policy tools to promote the deployment of renewable energy capacity. Previous papers have mainly considered one or a handful of policy tools at a time, hence the literature lacks a clear taxonomy of available options to policymakers and the latest findings regarding their effectiveness. The main method of research has been secondary, in other words, literature review, with which I have designed a framework for the different available policies. Based on the findings of numerous studies, I recommend feed-in tariffs as the most effective policy tool in promoting renewable capacity additions at manageable costs. I also highlight the importance of combining investment based, operating support and consumer facing policies in a multi-faceted approach to renewable promotion.
