Genuinely most "AI" DCs are spending less than 9KW on cooling for every 100KW of servers. If you were that bothered about getting that to zero, you could literally sink them into the ocean, build a heat network so the town can take the heat for free or use any of a dozen more established and practical ways to do that.
It's a bit demoralizing how many suggestions in this thread would have significant environmental effects beyond what large scale AI training already has.
I'm talking about the above proposals (albiet hypothetical) to either cover a pole of our planet in solar and other ocean based proposals--not solar in general.
It's a bit demoralizing people talk about AI training as if it were even 1/100th the environmental impact of the personal automobile or frequent airplane trips
