alt Hacker NewsNo you didn't; you pointed out why it is not, in itself, a significant issue in the first place (which rgmerk tacitly seems to recognize in his first response, through pivoting away from the 2% claim.) My position on this has been that if the issue really is over ~2%, there is a simple solution.
You even admitted it was a poor argument.
I'll state it plainly: to get to the same level of reliability as the existing grid with just wind, solar, and batteries requires unacceptable amounts of overprovisioning of these at high latitude (or unacceptably high transmission cost).
Fortunately, use of different long duration storage (not batteries) can solve the problem more economically.
