General Electric and Vestas Wind Systems were tied as the biggest suppliers of wind turbines in 2012, with each accounting for about 5.7 gigawatts of turbines, ending Vestas' 12-year run as sole market leader, according to a report by Bloomberg New Energy Finance. Siemens came in third, followed by Enercon and Suzlon Energy, the report showed. The wind-energy Production Tax Credit resulted in a record 13.6 gigawatts of new capacity last year in the U.S., where GE and Vestas sold 96% and 40% of their turbines, respectively, BNEF said.
