How is the European Union's biggest and most powerful economy making a clean break with coal, oil and nuclear energy? It is something most Americans would say is impossible, but already 25 percent of Germany's energy comes from renewable sources. It is on track to reach 80 percent by 2050, and some experts say it could reach 100 percent by then.Germany's energiewende, or energy transformation, is really a very American story that revolves around self-reliant individuals, a responsive democracy, and a national can-do vision. The book tells this remarkable and important story in a narrative directed to ordinary readers.
