You can buy all the GPUs you can possibly find. If you want to deploy 10MW+, it just doesn't exist.
These things need redundant power/cooling, real data centers, and can't just be put into chicken farms. Anything less than 10MW isn't enough compute now either for large scale training and you can't spread it across data centers because all the data needs to be in one place.
So yea... good luck.
Texas has a lot of wind. At this scale, it is mostly grid power anyway. Grid is a mixture of everything. Oh and solar has this pesky issue of not working in the evening, so then you have another problem... storage. ;-)
I should add... you want backup generators for your UPS systems? Those are a 4.5 years backlog.
Right now in the US there's about as much proposed renewable production planned and awaiting permitting as their is currently installed. It's the grid connections that are the long pole in expanding renewable use right now. And since the voltage that a solar panel outputs is pretty close to the voltage a GPU consumes you've got some more savings there.
There are still a lot of challenges with that but in general I think people should be looking for ways to collocate intermittent production of various things with solar farms right now, from AI models to amonia.
