As part of the Ragged Library, Dr Neil Robertson, at the University of Edinburgh’s School of Chemistry suggested “Sustainable energy – without the hot air” by David J. C. MacKay
Sustainable energy is set to be the defining challenge of the 21st century, hence everyone needs to read a clear and accurate book on the subject. This book systematically examines the main options for renewable energy and sets out to realistically estimate how much energy we could obtain and what steps we would have to take to get there. The key to the book is its approach of “Numbers, not adjectives” combined with its accessible, non-technical style.
This book is also available as a free ebook (in multiple formats) from the authors website at
