World renewable at around 12% * in 2022 [1], Nuclear is 9%. "2x current renewable and nuclear" for reclamation involves tripling current installations, and then it's another nearly 5x increase on current installations just to "stop emitting carbon".

Agreed with you that 7x isn't "several orders of magnitude" but it's certainly not happening anytime soon either.

If you use the "split by metric" option you get a much more optimistic graph for solar and wind:

The rollout of PV and wind is a modern miracle success story that many are intentionally ignoring.

Right, so you agree with my math? They were talking about just the energy to capture, so I gave that number first, followed by the number to do both.

The hard part of that 7x is switching our current energy uses. It's not the extra power. And a reliable grid with that many renewables should make lots of extra power as a side effect.
