The concluding chapter first summarizes some of the volume’s main results along the four evaluative themes. In terms of coherence and management, the three policy fields under scrutiny – renewable energy, fossil fuel subsidy reform and carbon pricing – are roughly marked by coordination, rather than competition or outright harmony. Regarding legitimacy, the specializations and work backgrounds of stakeholders lead to considerable variations in their perceptions of institutions. For effectiveness, institutional complexity plays both a supportive and a hindering role across all three cases. Following the summary, a series of policy recommendations are developed, including: improving awareness of each other’s activities to avoid duplication of efforts and conflicting messages; aligning interpretations of central concepts, i.e. what constitutes renewable sources of energy, fossil fuel subsidies and carbon pricing; building stronger connections to counterparts in other areas of the climate-energy nexus and beyond; and entrusting one institution with an orchestrator role. Finally, the chapter suggests a future research agenda on the governance of the climate-energy nexus, e.g. to learn more about the causes of institutional complexity, to identify conditions for successful management efforts, and to examine further sub-fields and even other domains outside the climate-energy nexus.
