“Analysts at Jefferies expect costs of 2 billion euros in their calculation, 1.75 billion for onshore and 250 million for offshore.”

Since this topic recently came up, I thought this was interesting

A small wind farm in Canada on Prince Edward Island (PEI) has a 60% failure rate. In the article, the turbine bearings are blamed, but that isn’t confirmed. The turbine manufacturer is Acciona, which I believe is a Spanish company.
