It depends. At my electricity cost, 1 hour of 3090 or 1 hour of Rtx 6000 would cost the same 0.45

Just checked vast.ai. I will be losing money with 3090 at my electricity cost and making a tiny bit with rtx 6000.

Like with boats it’s probably better to rent GPUs then buy them

(you should also be compensated for the noise and inconvenience from it, not only electricity.) It sounds like you might rent it out if the rental price were higher.

Would a solar panel setup be an option for fixing that? :)
