Now you are being just as intentionally over simplistic the other way. Electricity production and storage from rebuildable sources is not without losses. Round trip electrolytic Hydrogen production is 30% for example. And you are ignoring the fact that the recent examples I gave have already stated total energy requirements that were cut to 1/2 of the current levels. Which is what the studies have shown would be real world feasible with a complete and ideal electrification of everything.
And you are repeating the same mistake that the media has taught you by saying that "we need only 900-GW worth of CAPACITY for our requirements".
When in fact the capacity factor for the best solar farm in the USA is 31%. And onshore wind in ideal locations will be similar. Solar farms in my area average 13.7% capacity factor. Onshore wind barely more.
So we would need 3-TW CAPACITY of rebuildable energy capacity using your number. 5-TW using mine. Plus storage. We are not that far apart. Either one is immense in real world scale as I have shown repeatedly.
I wish we could stop these back and forths. It is a waste of time.
I'm not anti rebuildable energy. I'm pro math.
