简介 · · · · · · 　　The quest for safe, secure and sustainable energy poses one
　　of the most critical challenges of our age. But how much
　　energy do we need, and can we get it all from renewable
　　sources? DavidMacKay sets out to find the answer through
　　a forensic numerical analysis of what we use and what we
　　can produce. His conclusions starkly reveal the difficult
　　choices that must urgently be taken and readers interested in
　　how we will power our society in the future will find this an
　　illuminating read. For anyone with influence on energy policy,
　　whether in government, business or a campaign group,
　　this book should be compulsory reading. This is a technically
　　precise and readable account of the challenges ahead.
　　It will be a core reference on my shelf for many years to
　　come.
