I have written a detailed (thus long) book review at http://www.cypenv.info/books/files/mackay.aspx
The book in question is arguably the best one I’ve read on energy and its impact on the environment, if only because it is easy-to-read and sometimes downright funny. It has another outstanding merit, besides being technically sound: you can download it for nothing, yes, free-of-charge, gratis, zilch!
The last paragraph of my review reads:
In my view, it doesn't matter two hoots where you live; this book is relevant to where you are and who you are. I do not hesitate in recommending it to anyone with just, at the least, the very slightest interest in the world around him or her. It doesn't cost you a penny to download it from the Internet, especially if you don't mind reading it off the screen. I bought the cheaper hard copy version because printing it out would have cost more than purchasing it (my Scottish blood comes to the fore!). Finally, I emphasise that Prof MacKay has written it to be eminently readable and he has a great sense of humour, as well as being right with his reasoned arguments (at least, for 98% of the time, in my opinion!).
