Book excerpt: This book analyses the trilemma between growth, energy security and climate change mitigation and, breaking from scholarly orthodoxy, challenges the imperative that growth must always come first. It sets forth the argument that a steady-state approach is a more appropriate conceptual mindset to enable energy transition, sets out a steady-state energy policy, and assesses the projected outcomes of its implementation in the realms of energy security, geopolitics and development. By exploring in depth the implications of such a shift, the book aims to demonstrate its positive effects on sustainability, supply security and affordability; to showcase the more favorable geopolitics of renewable energy; and to unpack new pathways towards development. By bringing together ecological economics and mainstream energy politics, fresh insight to energy and climate policy is provided, alongside their broader geopolitical and developmental ramifications.
