At the northern end of Denmark’s Jutland peninsula, the wind blows so hard that rows of trees grow in one direction. The relentless weather — and the real-world laboratory it provides — has given the country a leading role in transforming #windpower into a viable source of clean energy. After energy prices spiked during the 1973 oil crisis, Danish entrepreneurs began building small turbines to sell. “It started out as an interest in providing power for my parents’ farm,” said Henrik Stiesdal, who designed and built early prototypes. The initial #windmills had quality problems. Now, though, they’re giants. The industry has grown to be dominated by companies like Siemens Gamesa Renewable Energy. Here, @rasmusdegnbol captured prototype Siemens wind turbines whirling at a testing site in Osterild. The biggest turbines here stretch more than 600 feet high. The largest rotor blades can reach 270 feet in length. And the price tag? Up to 10 million euros (more than $12 million). Wind is now a major power source in parts of northern Europe. Andreas Nauen, the chief executive of Siemens Gamesa’s offshore wind division, is optimistic that new markets will emerge in Asia and the U.S. “This is real,” he said.
