Germany increased its wind power production by 1,668 megawatts last year, maintaining its big lead as the top wind power powerhouse in the world. Germany now has the capacity to put out 6,113 MW of wind power, compared to about 2,500 MW by the U.S., the world’s second largest wind producer. Germany’s wind units now cover 2.5 percent of domestic demand for electricity. The European Wind Energy Association hopes that Germany will have a 22,000 MW capacity by 2010. Peter Ahmels of Germany’s Federal Wind Energy Association attributes the rapid growth of wind power to last year’s Renewable Energy Law, which has stimulated investment in the industry.
