Book excerpt: In this timely book, former Secretary of Energy Spencer Abraham debunks the myths that warp our current debate over energy, and offers new solutions to the real problems we face in America. Drawing on the very latest thinking from experts in industry and academia, and his own experiences running America's Energy Department, he proposes a fresh approach to meeting our daunting energy threats. This book effectively answers how America and the world can overcome the challenges of rising global energy demand, geopolitical disruptions of the energy marketplace, and the environmental impact of producing and using energy. What emerges is a pragmatic energy strategy that calls for blending a variety of energy sources including nuclear, clean coal, solar, wind, and natural gas with a more determined effort at improving energy efficiency through the deployment of smart energy grids and buildings, to help meet our challenges while preserving our economy and environment. Coming in the midst of a national debate about global warming, energy dependence and rising energy prices and rich with anecdotes from the author's service in the Senate and cabinet, this book is a clarion call that will help shape our energy future.
