A proven framework is vital to governing energy at the regional level, so as to ensure abundant modern energy access while achieving a net-zero economy. This book explains the governance of regional energy systems from a unique and distinctive international political economy perspective. The book conducts a comparative institutional analysis of the ECOWAS and EU energy regions, and highlights shifts from monocentric to polycentric energy governance. It charts a way of developing a robust regional energy governance regime based on the ‘design principles’ of Nobel laureate Elinor Ostrom. Aimed at political scientists and political economists with an interest in energy studies and comparative regionalism with a focus on the Global South and North, this book will appeal to students, academics and policymakers.
