Understanding the spatial unevenness of regional renewable energy deployment: insights for policy design

Abstract

Background This paper suggests that renewable energy (RE) deployment processes and their spatial unevenness can be explained by analysing the socio-material dimensions of RE. It explains how particular regional RE paths come to be favoured or hampered, and identifies factors that have contributed to these different outcomes. The paper shows the merit of investigating regional agency in energy research. Methods Using a novel analytical framework, the research performs a comparative case study analysis of selected regions in Italy and the UK, drawing on data obtained via documentary analysis and extensive in-depth interviews. Results The factors that explain regional variation in RE deployment are highlighted, providing evidence of how the distinctive features of RE deployment in five different regions arose and could be identified. The paper shows that understanding the socio-material dimensions of RE offers opportunities to understand the spatial unevenness of RE deployment at the regional levels and how to address it. While some regions have managed to successfully align their strategies and governance in order to maximise their RE potential, others have been less effective. The key features that influence the pace and direction of RE deployment at the regional level are i) the ways in which targets and resource availability are seen as drivers for RE deployment, ii) the degree of political autonomy in planning and the capacity to facilitate consenting processes at sub-regional levels, iii) the political will for RE expansion, elite consensus and the presence of relevant industry actors, and iv) the participation and involvement of regional government, even in the absence of formal regulatory powers, in shaping essential energy infrastructure investment. Conclusion While institutional capacity, planning and governance, the variety of actors and interests, compelling visions and credible expectations are all necessary prerequisites for coherent policy outcomes, the effects and degree of success can vary. This variance is influenced by the peculiarities and specificities of the regional contexts in which RE projects emerge. By identifying which aspects tend to constrain or enable RE deployment at the regional level, the paper helps to reveal the policy challenges that emerge and how they might be addressed.
