A recent trip around Europe via high-speed rail revealed a landscape dotted with enormous wind turbines and solar installations. But no country on the continent has made a greater push towards renewable energy than Germany. In Germany there are residential rooftop solar installations all across the country thanks to feed-in tariffs from the German Renewable Energy Act of 2000. Besides Germany, I also saw lots of wind farms in the United Kingdom, France, Spain and other European Union nations.
Here are solar and wind photos from Germany and Spain.
