12. Half of the units are stopped because they're either broken, or the wind isn't blowing.

They aren't stopped - ever - to balance load (occasionally they're locked down in extreme wind conditions to prevent damage).

Your fanciful idea that they'll all fill in for each other is not backed up by real world experience:

"A single wind turbine is highly intermittent. Theoretical arguments often claim that wind farms spread over a geographically diverse area will as a whole rarely stop producing power altogether, however this is in contradiction to the observed variability in total power output of wind turbines installed in Ireland and Denmark."

Thanks for having a civil discussion on this but I can see your mind is made up. I don't believe it's made up on the best information, and you don't believe that adding nuclear (especially safer Gen IV nuclear) will make the "whole country radioactive". There's much more practical experience with nuclear than the renewables gamble, and in my opinion we don't have the time or resources to accept that gamble.
