Many wind turbines are now 20 or even 25 years old. This increases the risk of serious accidents, of which some failures have already been reported. TÜV therefore demands the introduction of a mandatory inspection program in Germany.
The damaged turbine at the Alpha Ventus offshore wind farm is set to be repaired with a replacement nacelle.
The damage at the offshore wind farm, "Alpha Ventus", located about 45 kilometers from Borkum, is considerably more serious than initially known. At the beginning of April not only did the plastic covering crash 90 meters into the sea, but half of the nacelle fell off as well. Experts are now investigating whether it is a single incident or possibly serial damage. More than 120 turbines of this type are installed in the North Sea.
The cause of the accident is currently under investigation. Mayor calls for construction freeze
In the past four weeks, four giant power-generating wind turbines in Germany have either toppled over or experienced broken rotary blades. Now the question is: How safe are wind turbines really?
So far the investigation has found that one of three blades failed catastrophically, thus creating a huge imbalance that caused the tower to buckle 15 meters above the ground and led to the structure crashing down. ...The incident comes weeks after a similar turbine collapse in the Mecklenburg Pommeria town of Süderholz.
Three days after the disaster of a wind turbine near Leisnig in Central Saxony, a technical defect has been found as the cause of the accident. After completion of the investigation it was clear that one of three rotor blades was broken.

On Thursday, a wind turbine burned in Lathen (Emsland). The total loss, according to police was about 500,000 euros. The fire was believed to have been caused by a defective gearbox casing. Firefighters were at the site in the morning but the situation was not under control until afternoon. By the time they arrived the nacelle and the rotor blades were already in flames.
Early morning, last Saturday a windmill near Brandenburg an der Havel lost a blade. The failure occurred after having operated for just 14 years. The life expectancy was at least double that number of years. The citizens' group "Save Brandenburg" warns of the dangers of wind turbines.
Clouds of thick black smoke filled the air over Oederquart district Stade. The huge turbine standing around 70 meters kept attending fire departments from working to put the fire out.

RWE Innogy has temporarily shut down its 295MW Nordsee Ost wind farm in the German North Sea last Friday after a blade broke on one of the project’s 48 Senvion 6.2M126 turbines. ...Nordsee Ost blades are 61.5 metres long and weigh around 22 tonnes.
A wind turbine in Aurich-Pfalzdorf caught fire Sunday night. Because the flames roared at a great height, the fire department could not put it out.
A large part wind turbine collapsed to the ground on Saturday. The turbine was part of a facility located at Koßdorf (Elbe-Elster) in the south Brandenburgs.
In January 2013, the four turbines were erected and placed in operation on the reclaimed mining area behind the 540 freeway. But after 16 months it is noticeable that the ground on which they were built, which was not reinforced prior to construction, but artificially piled up is sagging under the weight of the towers.
A Vestas 67-meter-high wind turbine burst into flames late Friday night causing a loss of around 1.2 million euros. The cause of fire is still unknown. The Vestas 1.65 megawatt turbine located between Echtrop and Bergede drew 20 firefighters to the scene. Personal safety was a priority so the task force could only wait at some distance from the turbine to see how things would develop.
Turbine manufacturer Enercon is looking into why a blade recently crashed to the ground at a German wind farm owned by juwi. According to Enercon, the incident involved a E-126/6 MW wind turbine.
