Sustainable Energy

We are pleased to announce the launch of Sustainable Energy by David JC MacKay.

"This is a brilliant book that is both a racy read and hugely informative. It explains in ways that can be related to individual lifestyles, what needs to be done to save the planet and how it might be done. It shows quantitatively in ways that are easy to understand, why trains are potentially more energy efficient than cars, how cars might become far more efficient but why planes cannot, and how much land area that might be taken up by wind farms, among many other often surprising facts."

- Prof David Newbery FBA (Director, Electricity Policy Research Group, University of Cambridge)

"Sustainable Energy" is available to purchase now, or as a free download.
