How Cold Is It In Minnesota ?

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

From KSTP-TV:

“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?
