Free Stuff for Every Reader!

Here are Seventeen/ten there's two things we really like: Free stuff and good quality, no-nonsense information. That's why, when picking up on my too-long-abandoned theme of trying (probably unsuccessfully) to add clarity into the debate on solutions to the energy problems, I was pleased to find a new book.

The book in question is called Sustainable Energy - Without the Hot Air by David MacKay. This book is all about quantifying the scale of the different factors involved in our usage of energy and our options for generating it. The book is based on information for the UK and often relates the the authors own experiences, however all the figures are arrived at in a way that makes it easy for the reader to calculate their own values. Also really helpfully huge swathes at the end of each chapter are dedicated to the sources for the information, so if you need more detail you can easily find it. In my opinion the author occasionally errs on the generous side when calculating what renewable energy could be generated, but he is always honest about this in saying why and by how much.

The best part is the the book can be downloaded for free as a PDF from www.withouthotair.com (or a hard copy can be purchased). I think everybody should read it.
