"For decades, Hermann Scheer was one of the world's leading proponents of renewable energy. In this, his last book before his death in 2010, he lays out his vision for a planet 100 per cent powered by renewables and examines the fundamental ethical and economic imperatives for such a shift. And most importantly, he demonstrates why the time for this transition is now. In Scheer's view, talk of "bridging technologies" such as carbon capture and storage or nuclear energy - even (and perhaps especially) by environmentalists - is actively damaging the more pressing agenda of the move to 100 per cent renewable energy. Instead, he offers up examples of the technologies which are working (economically) today and details the policy and market conditions that would allow them to flourish. In 1993, Scheer's A Solar Manifesto laid the foundations for the road which has led to annual newly installed renewable capacity today rivalling that of conventional power sources. The Energy Imperative provides a practical, inspirational map for the next stage of the journey"-- Provided by publisher.
