The attached detailed table includes all documented cases of wind turbine related accidents and incidents which could be found and confirmed through press reports or official information releases up to 31 March 2016. CWIF believe that this compendium of accident information may be the most comprehensive available anywhere.
Data in the detailed table attached is by no means fully comprehensive – CWIF believe that what is attached may only be the “tip of the iceberg” in terms of numbers of accidents and their frequency. Indeed on 11 December 2011 the Daily Telegraph reported that RenewableUK confirmed that there had been 1500 wind turbine accidents and incidents in the UK alone in the previous 5 years. Data here reports only 142 UK accidents from 2006-2010 and so the figures here may only represent 9% of actual accidents.
The data does however give an excellent cross-section of the types of accidents which can and do occur, and their consequences. With few exceptions, before about 1997 only data on fatal accidents has been found.
The trend is as expected – as more turbines are built, more accidents occur. Numbers of recorded accidents reflect this, with an average of 21 accidents per year from 1996-2000 inclusive; 57 accidents per year from 2001-2005 inclusive; 118 accidents per year from 2006-10 inclusive, and 164 accidents per year from 2011-15 inclusive.
