Rival Siemens Gamesa last month unveiled a plan to cut 2,900 jobs, mostly in Europe, after issuing a string of profit warnings this year. Profit at Danish wind turbine maker Vestas has also taken a hit. The troubles at GE's onshore wind unit, which accounted for 15 percent of the company's industrial sales last year, are also affecting the performance of its overall renewable energy business. In July, the company blamed its North American onshore wind business for two-thirds of the decline in its second quarter renewable revenue. GE has made turning around its onshore business a priority as it prepares to spin off its energy businesses, including renewables, into a separate company in 2024.
