Another POV is, if datacenters are really constrained by power, by all means, offer users a discount when their queries utilize solar. Millions of Americans drive further to save cents to fill up their tanks - you can’t say there isn’t precedent among normal people to deal with this. The better question is, is it really a constraint?
The customers time is not flexible like that.
And every second GPU is not working, it's not making money
Doesnt really work, as the biggest cost is buying GPUs etc which has to be paid for, and leaving them idle when the sun isnt shining doesnt pay the purchase costs. Their are industries where this does work though.
