This unique collection brings together his most important and influential writings and forms an inspiring resource for anyone wishing to gain a deeper understanding of the issues which lie at the heart of sustainability and energy challenges. Featuring work from across his long career spanning energy, design, transport, climate, security, law, mountaineering, politics, proliferation, health, business, biotechnology, physics, and politics, the book explores the relevance of the ideas to the sustainability problems we face today - a relevance which is often [exasperatingly] evident.
