My posting below about the lack of wind power during extreme cold drew several comments, some of which disagreed. Anthony Watts cross-posted it at WattUpWithThat and his commenters were even more vocal in disputing my contention that wind power is unreliable in cold weather. Thanks for the comments, I appreciate them.
Let me illustrate my point about cold weather here in Kansas. Below is a photograph of the Beaumont, KS wind farm, halfway between Wichita and Chanute:
Chanute set a cold weather record this morning of -16°F!
Wichita reached -6°F:
What were the winds? Every weather station in the region was below the minimum 7 mph threshold needed to turn the blades thoughout the night. These were the 8am readings.There have been multiple studies in Europe and at least two previous instances (Minnesota and, in 2008, Texas) where wind power failed during extreme cold.The fact that wind power is not reliable in extreme cold is indisputable.
