Structural Failure
Wind farm technicians and officials with EDF Renewable Energy believe one wind tower, just northeast of Dexter, was struck by lightning on April 24, which mangled one of the structure's 37-meter, 14,000-pound blades.
The mystery behind a fallen turbine blade at the Ocotillo Wind power plant east of San Diego has led the manufacturer to curtail operations at select wind farms around the world. ...The fallen blade ignited new safety concerns among critics of the plant, who posted photos and videos to the internet of the crumpled white tube.

A Siemens spokeswoman explained that "when a turbine is curtailed, it means the load on the blade is significantly reduced compared to normal operation." The company said there were about 700 such turbines deployed around the world, with most - around 600 - in the United States, and all those turbines were being examined.

These turbines will remain curtailed until it can be determined they are not at risk of a similar malfunction.
The Iowa incident took place in April at MidAmerican Holdings' 200-megawatt Eclipse wind farm.

This wholly avoidable public health and safety hazard occurred just one day after San Diego County Board of Supervisors approved the revised Wind Energy Ordinance & Boulevard Community Plan to remove community protections to allow 500 foot tall industrial wind turbines on private land in previously protected areas near homes, recreation areas, and sensitive wildlife.
The 1.5-megawatt turbine was commissioned in March 2009 but was shut down June 18, 2012, after the gearbox showed significant wear. The faulty gearbox was no longer covered by warranty, and the manufacturer of the turbine, AAER Wind Energy of Quebec, is no longer in business. Three of five turbines of the same make and model erected in California and Templeton, Mass., also suffered gearbox failure.

Turbine fires have been known to start forest fires, according to the Confederation of Fire Protection Associations in Europe, which in September 2012 released a document of best practices and guidelines of how to handle fires at wind farms.
The European document warns that these type of forest fires can be difficult to extinguish.
A 90ft turbine in Aberdeenshire has fallen after being battered by 70mph gales.
"It's worrying because there are so many turbines in this area. If someone had been walking by when this came down it could have been very serious."
A blade on a wind turbine broke loose and landed in a field in Adair, Iowa. KCCI reports officials said they are still trying to figure out what went wrong. The turbine manufacturer is leading an investigation into the accident.
Dan Morgan “saw an orange fireball a couple of miles from the front yard, so I thought I better investigate this,” before driving over to get a closer look.
The Goderich Fire Department was called to the scene, but with the blaze 100 metres in the air, there was little that could be done.
A technical examination is being carried out to try to establish how a large wind turbine near Maas, close to the Ardara area of Co Donegal, came crashing down on Thursday. While winds were heavy at the time it was nonetheless understood that these turbines were engineered to withstand such conditions.
