Barry, i put up every thing I found yesterday. I suspect an annual teacking of wind output for the United States would be a real eye opener. A couple of years ago, David Roberts of Grist let slip that as much as 12 hours of electrical storage would be required to make American wind reliable over 11% of the time, and 10 more hours of storage would add another 2% if time. Roberts did not reveal how much storage would be needed to get the last 2%. I take that to suggest that about 15% of the time, American wind resources would be absent for prolonged periods of time from a few minutes to one or more days.

Thanks for tracking this down, Charles. I find this graph endless fascinating to watch on a day to day basis (in a morbid sort of way).
Have you come across any similar data streams for other countries?
