It's very difficult for countries to simultaneously transition away from coal and increase electricity per capita consumption
Arguably only a few countries have pulled it off at the same time:

We use the GIS tool to develop a notional framework for prioritization of cobalt reserves in the 13-state region considered, to help inform land use prioritiation and potentially develop programmatic EIS in the future for new mines

But LBNL expects further improvements in PUE across the industry
(I'm guessing this is weighted by the fact that the majority of growth in overall data centers in the coming years is from hyperefficient large-scale colo/hyperscalers)

data centers are not exactly base loads part 2!
(note operational time of server is correlated but not exactly the same as facility level power draw due to idle power draw, cooling, etc)
