Oh this is a political problem then, not physical. China adds as much capacity annually as the US totals. We will deploy more as the industry scales, I don’t expect it to be a bottleneck.

I agree 1kW is a lot for a humanoid, I can’t predict how much of that will be necessary. People run 1kW PCs at home though so not that bad.

This sounds like you misunderstood my point.

This isn't a China-renewables-vs-US-renewables problem, it's the total electrical supply worldwide from all sources that's only around 350 W/person.

With regard to renewables, the point is that *even though they're growing fast, even when baking in the assumption that we continue to deploy more at a sustained compounding genuinely exponential rate, then it's still a decade away from being relevant*. At which point, the effect of a combined efficiency boost to hardware and software also becomes relevant.

*Some* people run 1kW PCs. Even in the USA with relatively high energy supply per capita, were *everyone* to do this it would either cause brownouts, or increase energy prices by (best guess) something like 5x to reduce demand by the same degree elsewhere in the system.
