The Windmills of Spain

Don Quixote has made the old windmills of Spain famous for the past four hundred years, but new Spanish windmills are now achieving a prominence of their own. Spain's national newspaper, El País, reported this week that on March 5 windmills generated enough energy to meet 29% of the demand for electricity at 11:10 in the morning, and more than 40% of the demand during several of the early morning hours.

Windmill farms with a hundred or more mills are a common site when driving across the plains, though usually only a small portion of the mills are operating. Indeed, the country's windmill network was only functioning at 74.5% capacity when the March 5 record was established.

The bigger news that El País reported, however, was that in the months of January and February, Spain exceeded the goal of generating 30% of its electricity with the renewable sources of wind and water. In 2001 the European Union established a target for its member countries to satisfy 29.4% of their electrical needs with renewable sources by 2010. Though Spain experienced favorable conditions of wind and rain in the first two months of this year--as well as diminished electricity demand due to the economic crisis--it appears to be well on its way to maintaining its place as one of the leaders of renewable energy production and management. According to El País, only 10% of electricity in the U.S. is generated by renewable sources, and in the UK, it's less than 5%.
