Energy is a commodity so the price will be very similar for the same goods. What they tack on as taxes might be different.
Afaik electricity is around 7c/kWh in China. I got 8c/kWh 2y contract a couple weeks ago here in Finland. Though have to add 4c/kWh for transfer to that (no clue if the Chinese prices I could find include that). Commercial prices are less then that (no VAT and possibly lower power tax bracket. The 8c includes all taxes/fees)

No. There is no argument being made regarding "legacy hardware’s power inefficiency isn’t as big of a deal when electricity prices are lower".
That's just complaining that Western Europe has high energy prices compared to China without taking into consideration how different these economies are.
Which is why I suspect most nominal "data centers" are fronts for crypto mining, an activity that seeks out the cheapest energy.
