New study finds wind farms last only 50% of claimed lifetime

The Hockey Schtick
"A peer-reviewed study finds from actual performance data of wind farms in the UK and Denmark that the life of wind turbines is only about 50% of that claimed by the wind industry. The report finds the performance "of wind farms declines substantially as they get older, probably due to wear and tear" and that "This decline in performance means that it is rarely economic to operate wind farms for more than 12 to 15 years. After this period they must be replaced with new machines, a finding that has profound consequences for investors and government alike."
