It's as if trucking companies flooded the highways with so many trucks that people couldn't commute to work anymore.
So, we're talking 40GW. Lets see what China does:
https://energyandcleanair.org/china-energy-and-emissions-tre...
"In the first two months of 2026, China added:
32.5 gigawatts (GW) of solar power capacity, down 18% from last year. 11 GW of wind power capacity, up 19% from last year. 20 GW of thermal power capacity, up 414% from last year. 1.2 GW of hydro power capacity, down 36% from last year. 1.2 GW of nuclear power capacity. "
2.2-2.5 GWdc solar capacity which at 600W/panel amounts to 14-17sq mi plus additional 8-12GWh of storage to deal with nighttime, two-three days of cloud cover is not going to work with these numbers.
Ballpark 5-7BN$
Nuclear otoh, 1GW continuous - gives constant power, badly managed first of a kind (or first one after decades) build will be at around 10-15BN and that’ll cover two 500MW data centres.
There’s also the second/third degree order effects nuclear power stations have of creating jobs and industrial manufacturing demand. To run a nuclear power station you need to employ 1000 people (engineers plus support staff) - that’s a small town’s worth of adults. So you’ll need a town with a school, hospitals, stores - those need staffing as well.
Unfortunately building nuclear is not something that’s currently a feasible path as it requires patient capital and long term vision and planning.
So gas turbines it is at around ~1BN$
In Europe, we approach energy generation as a political, or climate problem. We are building solar and wind power sources, not to make energy cheaper, or to make grid more resilient, but to fulfill an ideological goal.
The results are, not great, to be honest. The energy prices have increased substantially, and are now driving our chemical industry bankrupt.
Edit: I do not dispute the climate change. I am only highlighting impacts of current policy.
yes, they don't seem to fall for the "solar is unstable" trap and recognize new reality - the solar + wind smoothed by nuclear/gas is the new baseline
Without enforcement it will happen continuously with snail pace
And grid battery works and is cheap enough now.
But I haven't looked into where these datacenter are being placed, I'm assuming that although solar is cheap now, the surface needed would make the purchase of nearby land probably not worth it. These new categories of datacenters are becoming very energy dense...
- battery storage
- and in the article
"However, AI labs and some hyperscalers have relaxed those requirements as there is now a lower uptime tolerance applied to both inference and training, not just training. Many of Meta’s self-built AI datacenters, for example, target just two nines of uptime and forgo backup generators entirely, as detailed in our Industrials Model."
There is money now for a huge investment boom, which is what is happening in the US and China. With EU failing completely.
Not in western Europe, because they spent almost all their excess economic output over the past few decades on welfare/transfer payments.
But fuck them, they are poor people so we don't care about them /s .
Additionally, people against data centers are accused of being paid by China [2]
