Denmark has among the most successful renewable energy programs in the world, with 40 percent of its electricity coming from renewables, mostly wind. But it’s significant that the program was rolled out in the 1980s, before the free trade era began, when there was no one to argue with the Danish government’s generous subsidies to the community-controlled energy projects putting up wind turbines (in 1980, new installations were subsidized by up to 30 percent).
