No. This is disingenuous. Something that consumes electricity doesn't care where the electricity comes from. Fix the power source, and you automatically fix every single consumer in existence at once.
narrowing the topic, that is exactly the quality that energy transition theorists are leaning on. The electrical grid is uniquely able to maintain a stable engineered and market place while inputs and loads change quite a bit.
I think your comment is the disingenuous one. We have no time left and "Fix the power source" is happening way too slowly in the real non-theoretical world. But what can happen in zero time is to not build another data center for something that nobody really needs.
