No worries about the AI energy load ~ 40% increase in USA energy output by 2050.
Small modular nuclear reactors are coming to the rescue.
We will have a live speaker on this topic on Feb 12.
George W Griffith PhD from the Idaho National Laboratory, part of the Dept of Energy, will present this topic.
We are all saved.

How Running AI Computations Backwards Can Save Energy

Fascinating discussion, and makes the concepts much clearer.
BTW, reverse-time computation has nothing to do with time as in space-time. It's a technique of doing some calculations back-to-front, as well as front-to-back. It can be much more efficient in terms of CPU and NPU loads, as well as making the computations happen faster.
Pruning of irrelevant background details has an even greater effect on computational efficiency.
Given the huge energy demands of AI, as well as AI's tendency to use up a lot of GPU and other hardware resources, this is an important area of concern.

I have been getting this very interesting magazine for a couple of months. It is mostly short stories on a VERY wide swath of technical issues. Seems to be UK based. It is a weekly of about 40 pages, and the 12/29 article had this article on the cost of AI computing and the way in which computers use so much money erasing data. I only partially understand it but it appears to be well worth reading. Then someone with more knowledge that I can explain it at a meeting.
