January 10, 2013 (San Diego’s East County) -- How long can we expect wind turbines built in our region to last? It’s a key question, since early wear and tear can sharply reduce efficiency, sticking ratepayers with hefty electricity bills. Now, a new study of 3,000 wind turbines finds that they are wearing down faster than manufacturers expected. The study, which claims to be the largest of its kind, examined both onshore and offshore turbines operating between 2000 and 2001.
