Thanks to EU Referendum I found myself perusing the "Summary of Wind Turbine Accident data to 31 December 2010". It is fascinating. Did you know that there were 18 incidents of blade failure last year? Or that pieces of failed blades have been known to travel over 1300 metres (6.5 furlongs or 0.8 mile)? However, for me the most remarkable fact is that there were 5 fatal accidents last year, clearly it is a dangerous business.
