Anyone offering or believing that bumper sticker solutions exist for reconciling global energy and environmental concerns in the twenty-first century should be humbled after reading this book. Valentine, Brown, and Sovacool offer an erudite, sobering, and compelling analysis of the complicated challenges, tradeoffs, and opportunities involved in transitioning globally to a renewable energy future. Writing in prose accessible to experts and laypersons alike, the authors adroitly integrate a multidisciplinary body of research (pro and con) to make a full-throated case for shifting to a renewable energy future. Readers may or may not agree with their arguments for an energy reset, but they cannot ignore the data, realpolitik, and strategic analysis the authors provide to explain and address the often halting and mostly patchworked progress made so far.
