Denmark earned more foreign currency from sales of wind turbines in 1993 than at any time since the California wind rush of 1985. Exports doubled last year compared with 1992 and turnover reached DKK 1501 million ($220 million). In 1985, when generous California tax credits created a market for thousands of wind turbines, turnover was DKK 2275 million. Statistics from the Association of Danish Windmill Manufacturers further reveal that a total of 572 turbines, some 180 MW in nameplate rating, were sold to 13 countries in 1993, with Germany, Britain and the US leading the field (see table). Since 1980, Danish wind turbine manufacturers have sold a grand total of 12,898 wind turbines, now installed in 38 countries. The world total of installed wind plant made in Denmark is 1,628 MW, according to the association.
