Nashtifan, a village in northern Iran, is still using an ancient energy source: windmills. The region is subject to strong winds, and windmills have been in use there for 1000 years. And amazingly, those ancient windmills are still working. The structures, made of clay, straw, and wood, also protect the village from the destructive elements of those powerful winds.
