David MacKay has written a fascinating, immensly readable book about the opportunities and realities of sustainable energy. Although it is written with reference to England, it is still extremely relevant to us here in the US. This book is being touted as seminal by just about everyone who studies energy issues and has excellent reviews from most every major news organization in the US and England.

In the true spirit of free information dissemination, MacKay has made his book available for free to read or download from the internet. If you go here:
