There’s nothing quite like an excellent example. The village of Wildpoldsried, in Germany, is just that; a great eco-example that all communities should be looking into. This village produces 321% EXTRA energy and makes money by selling it back to the national grid.
This is not a new concept but this village has had the foresight to get it right. They have windmills and solar panels (on private & public buildings) which provide for all their needs AND produce 321% more energy. This energy is in turn sold back to the national grid, netting this village $5.7 million in annual revenue. For the full story and pictures, click the link below.
