There is an organization, the Caithness Windfarm Information Forum, that keeps data on wind power-elated accidents and/or design problems. Caithness is based in Great Britain, where homeowners have already grown tired of the noise and other wind turbine generated problems. Their "Summary of Wind Turbine Accident Data to 31 December 2008" reports 41 worker fatalities. Most, not unexpectedly, were from falling as they are typically working on turbines some thirty stories above the ground. In addition, Caithness attributed the deaths of 16 members of the public to wind-turbine accidents.
A summary of accidents includes:
• 139 incidents of blade failure. Failed blades have been known to travel over a quarter mile, and that is from turbines much smaller than those being manufactured today. This type of accident has caused some European countries to require a minimum distance of about one mile (2 km) between occupied housing and wind turbines.
•110 incidents of fire. When a wind turbine fire occurs, the local fire departments (without 30-story ladder trucks) can do little but watch. This isn't a problem unless the wind is blowing sufficiently to scatter the debris into dry fields or woodlands — or maybe onto your roof.
• 60 incidents of structural failure. This includes turbine failure and tower collapse failures. While not now a problem for the public — except having to gaze upon at a bent-over wind turbine — it may well become one as governments, under pressure from environmental activists, encourage marginal- and hastily-sited wind projects in urban areas where such an accident could kill and maim.
• 24 incidents of "ice throw" with human injury. These data may be a small fraction of actual incidences, with 880 icing events reported in a 13-year period for Germany alone.
