How Cold Is It In Minnesota ?

Cold enough to freeze your wind turbines, and stop your electricity.

“Wind turbines placed in cities across Minnesota to generate power aren’t working because of the cold temperatures.

The Minnesota Municipal Power Association bought 11 turbines for $300,000 each from a company in Palm Springs, Calif.

Special hydraulic fluid designed for colder temperatures was used in the turbines, but it’s not working, so neither are the turbines.

There is a plan to heat the fluid, but officials must find a contractor to do the work.”
I wonder what the electricity costs from a stopped windmill? And what you do when the windmill stops, along with your electricity? Anybody spot another problem with windmill use for electricity generation?
