Someone was to climb that damn thing and change the weight of the oil in the reduction gears every winter, or it sludges up, you can heat your oil too, that is how we pump oil in the north during winter.

With the installation of “cold weather packages” which provide heating to turbine components such as the gearbox, yaw and pitch motors and battery, some turbines can operate in temperatures down to -30C.

Sounds like a lot of these wind turbine failure stories boil down to poor engineering, not a problem with wind turbines per se. Bearings that can't handle the torque, systems that don't have heaters to handle cold weather, etc. This is all stuff that heavy equipment manufacturers figured out decades ago. If you can build a semi that can drive to the north slope of Alaska, you can build a wind turbine that will run in Texas in the winter.
