Americans do not need to be told how frequently "things don't work." Few of them, however, can realize how vulnerable the national energy system has become not just to foreign control of supplies but to nature, accidents, deliberate disruption, selfish interest and mischief. This book explains that, vividly. Even so, its most interesting parts concern the principles of resiliency that might be built into the system. When it comes to actual measures-smallness, decentralization, alternative sources and the like-the case again becomes highly controversial, as is to be expected from the pioneers of Soft Energy Paths.
