If you need to find information and opinion on sustainability, this book comes highly recommended: Sustainable Energy – without the hot air, by Prof David JC MacKay of Cambridge University. It’s free to download online.
Tony Jupiter, former Executive Director of Friends of the Earth, and Vice-chair of Friends of the Earth International, sums up the book as follows:
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? David MacKay 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.
It will certainly be on my reading list!
