Ballen, Denmark, is one of 18 small villages on Samsø, an island of 4,000 residents. The new Energy Academy with its 11 new jobs is located here, doubling as a meeting house and visitor center for those who come here from the world over to learn how to become 100 percent energy-independent. The island has 21 huge wind turbines generating over 104 million kW h/year, enough to power 26,000 homes. Sixty percent of the island’s buildings are heated by 4 solar district heating systems, with straw-burning back-up boilers; the rest use electric heat pumps. Cars run on electricity.
