Germany is proving that a rapid transition to renewable energy is possible.
Within four decades, one of the world's leading economies will be powered almost entirely by wind, solar, biomass, hydro and geothermal power.
As Germany is showing, it is very possible to get large penetrations of renewable energy while phasing out nuclear energy. With bold political and social support, a consistent incentive framework for clean energy investment, and creative thinking about how to deploy geographically-dispersed resources, Germany is undergoing a major transition in its energy sector.
Two experts on the German experience — Wilson Rickerson of Meister Consultants and Arne Jungjohann of the Heinrich Boll Foundation — describe how the country will "reduce carbon emissions 40% below 1990 levels by 2020 (and 80% by 2050)" without nukes.
