Forty years ago Sabana Grande, a small community in northern Nicaragua, was ravaged by war. Now you will find people sitting under solar-powered lights, eating solar-cooked chicken, and drinking smoothies made by a bicycle-powered blender. Sabana Grande (pop. 2,000), in the mountains of Totogalpa, about 20 miles from the Honduran border, has embraced a solar culture that has transformed the community.
