Thank you for reading! The prices in the iea chart seem to be a few years old.
This list (https://www.globalpetrolprices.com/electricity_prices/) has US prices at 14.9 US cents/kwh and China at 10.8 US cents/kwh as of Q2 2026.
Tbh hard to tell how accurate those are either.
The larger issue is that (apparently) new US data center bills aren't getting connected to the grid because of lack of capacity (and the lack of planned growth in that capacity) compared to the very high growth in Chinese installed capacity.
