Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

... and it may also be the beginning of the repowering sector in Germany, where older, smaller windmills from the early-mid 90's are replaced by newer models.  (will also assist emerging and 3rd world markets, where the reconditioned older turbines will go.)

About the 3rd world, how do wind energy works in places that get quite a few hurricanes each year ?

Almost since the beginning of commercial development, wind turbines have been designed to work with limited to no repair up to 125/mph 200 kph winds.  Survivable (with testing and repair) to 150+mph 240+kph.  Plus, hurricanes are known in advance, and steps can be taken to batten the turbines down.  since most modern (utility-scale) turbines only produce power up to 60 mph 96 kph 26mps very little energy is actually lost by these design standards.

Smaller scale turbines specifically for tropical areas or with high storm likelihood can feature tilt-down towers so the turbine can be lowered as a storm approaches.

In fact, Vergnet    in France does just that, for such markets.

the beginning of the repowering sector in Germany

In 2009, 55 turbines with 136.2 MW replaced the majority of the 76 decommissioned turbines with 36.7 MW. Indeed a jump from 18 (23.94 MW) last year, but in 2007, it was 45 (103 MW).
