I’ve let this distributed grid go on long enough, you need to pick your battle here, are you going to generate only in good locales or are you truly going to distribute and generate everywhere including some really crappy sites. See links for graphic example of my next point.
Wind Energy Resource Atlas of the United States
Now take those wind speeds from the calculations in post 78 and find your 42% sites and your 33% sites (8.4 and 5.8 m/s wind). Are they not geographically clustered? Does the bulk of the power fall in one time zone? Are there not great areas of the eastern portion of the country that are completely unsuitable?
Check out the seasonal variations:

This was the same thing that I was trying to reflect in the Danish data, that was not a fluke. |
What you need to look at are the certainty ratings of class
three/
four wind resources, and then show that it's impossible to generate enough for baseload via high certainty class 3/4 wind resources. The unsuitability of a particular potion of the states doesn't matter if we have a
distributed renewable grid. If you want to talk about
local renewable grids then the lack of available wind resources matters, but again, that's
not a
distributed renewable grid.

Again, if you're looking at
local renewable energy, having piss-poor generating potential in the NE is a problem, but that's
not a
distributed renewable grid. The time zone issues are only a problem for the western states, and they would only be insurmountable if there weren't any suitable resources available to pick up the slack at that time.

And yes Hydro-Quebec does have a HVDC line in its system.
Again more to follow.

Um, d00d, I'm pretty sure the T&D failures were the result of the ice storms, unless those hosers let their superscientists loose.
That said, don't cut corners on T&D. Build it properly and foreseeable natural disasters won't be a problem.
