A very important contribution. One of the huge comparative advantages of this book is the seriousness and knowledge about energy and efficiency. It explains how critical resource efficiency, relating to energy, but also to other scarce resources such as food, water, minerals, and time will be to managing the enormous geopolitical, economic, and environmental challenges in front of all of us today.
