Policy feedback and institutional context in energy transitions

Interest in policy feedback processes in energy transitions has grown rapidly in recent years. However, while it has provided interesting accounts of the mechanisms of stability or change, the policy feedback framework begs the question of why policy feedback dynamics vary so widely across cases. Existing accounts have tended to focus on the influence of ideas on policy design and on the role of interest groups. By contrast, the role of background institutional context in shaping policy feedback processes has been understudied. In this article, I develop a framework for identifying relevant types of institution that potentially shape policy feedback across different analytical stages of the feedback cycle. This approach is illustrated through the example of support policies for solar PV, where it is argued that a relatively small set of political, political economy and social institutions are likely to be important. The argument is then applied through a comparison of the evolution of solar PV policy in the UK and Germany, and the role of institutional context in explaining divergent policy pathways
