Denmark, the world’s wind-power powerhouse, has embarked on a 10-year government project to run an entire community, the island of Samso, solely on renewable energy. The country already gets 7 percent of its electricity from wind, and by 2030 that percentage should rise to 50, according to the Danish Ministry of Environment and Energy. Denmark’s eco-conscious populace is supportive of the shift to clean energy: Eighty percent of the country’s windmills are owned by individuals or cooperatives. Wind power has also become big business for Denmark, which manufactures more than 50 percent of the world’s wind turbines and exports them to 35 countries.
