Germany is leading the way in developing "green" technologies and has the most ambitious energy-saving program in Europe, aiming for a 30 percent reduction in energy usage by 2020, and a 30-percent renewable energy share, consisting mainly of biomass, wind, and solar. Germany's experience - its success and lessons learned - provide a solid evidence base from which nations like the United States can "leapfrog" Europe, and tackle even more pressing energy and climate change demands through deliberate public and private action.
