This book provides a comprehensive overview of the emerging interplay that runs between energy – seen as a basic need and a providential material service from the viewpoint of welfare studies – and eco-welfare, seen as an emerging analytical and policy paradigm that hold together the social crisis on the one hand, and the ecological crisis, on the other hand. At a time of energy transition, the interplay between the theoretical framework of eco-welfare and the topic of energy supply is little explored, and therefore, this book fills a need in the literature by providing a comprehensive framework to navigate this emerging relationship. Such a framework is strengthened by insights on energy poverty and renewable energy communities, identified as cornerstones of the analysis between energy transition and eco-welfare.
