This book is a call to action on climate change, filled with clear and detailed information on the strategies we need to adopt to ensure a sustainable future for the planet. Unlike other books on the subject, it brings together both the technology and policy issues to provide a truly interdisciplinary approach. Mark Diesendorf provides a guide to our future energy options, outlining the enormous recent changes in the energy sector in Australia and internationally. Diesendorf argues that we now have the technologies needed to transform our fossil - fuel based energy systems into an ecologically sustainable one, based on the efficient use of renewable energy. All we need is the political will to do so.
