That would be

A serious crane accident in Northern Germany involving the dropping of a large turbine rotor has been reported.
The accident involved a 1,200 tonne Liebherr LTM11200-9.1 erecting a large wind turbine in Hennickendorf in Brandenburg at the end of last week.
Reports are sketchy and the photos we have received do not show a great deal of detail. However local news stations say that a violent and unexpected gust of wind caused the rotor to take- off pulling the crane's boom and Jib with it, causing it to collapse. The boom, jib and rotor with its blades came crashing to the ground....
...The men working on the ground were able to scramble to safety and were unhurt, however there are reports that the crane operator may have been injured while jumping from his cab, and photographs suggest that part of the crane's boom fell onto the cab almost destroying it.

According to the
http://www.wind-energie.de/en/news/article/more-wind-power-capacity-installed-last-year-in-the-eu-than-any-other-power-technology/166/">German Wind Energy Association in 2009 the EU produced 163 TWh (0.59 exajoules) of electricity in 2009 from 74,767 Mega"watts" of capacity, not that there is a single wind plant on earth that actually reaches peak capacity for more than 10 minutes in a given year.
From this it is possible to calculate directly - assuming that one hasn't joined Greenpeace and thus has a fifth grade mathematical level, and can calculate how many seconds are in a year, and are familiar with what the meaning of the unit "watt" actually is - that the capacity utilization of wind power in the EU is 24.9%.
For comparison purposes, the three nuclear units at Palo Verde in Arizona, all of which can be contained in a single photograph, produce 0.105 exajoules of energy, or about 18% of the energy that the entire EU is able to produce across an entire continent from wind.
In real terms, using 2005 figures from the EU Energy Agency the EU consumed

of pure electricity.
It is useful to note that this is the consumption of
electricity and not
thermal energy.
I have experienced here that many posters, usually the ones with the biggest "renewables will save us" rhetoric are entirely unfamiliar with the second law of thermodynamics, which is why it is necessary to make the last point.
