Alternatively the crisis can be used to accelerate right development - quickly build up solar farms and transmission lines. Both of these can be done quickly if there were a political will. Yet, that will is missing.

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. "

Edit: to the proponents of nuclear - i think nuclear is very damaging to society as it promotes corrupt crony-government capitalism instead of market forces.

Right off the top of my head, to power a 500MW Datacenter we need:

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$

I like how balanced their energy mix is. It is very obvious that China is optimizing for capacity and availability. There isn't really a push for clean energy sources for political, or climate, reasons. They are deployed when it makes sense, backed up by robust coal and nuclear sources.

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.

If we build a terawatt of green energy capacity then turn around and immediately use it for datacenters rather than to replace fossil fuel generation, we haven’t gained anything. If anything we’ve lost out.

Yeah and the richest person on the planet with full vertical integration (with partner) Elon musk and Tesla aka solar roof and power wall wants to sell DC in space and hasn't fixed any use of gas turbine for Colossus 1&2.

Without enforcement it will happen continuously with snail pace

solar farms are worst kind of power source for constant loads like datacenters running AI training
