Hi everybody. I thought that I would share an observation. I drive by a large wind turbine every day on my way to work and have noticed that it is actually spinning faster on average now that it has gotten colder. I found this to be surprising. I am certainly no expert on the topic but common sense would suggest that a wind turbine would spin slower during the winter right? (due to the relationship of wind and radiation of energy from the earth) Anyway, I realize this observation is far from scientifically valid, based entirely on my observation of one wind turbine, at one location. I am sure there have been valid studies on this issue, but I thought that I would share some raw observations for what it is worth. Can anyone shed some light on this?
