"Don't use LLMs" is just another variant of "don't use electricity".
Reframe the problem like that and then realize that no one's going to do it: global electricity use is constantly increasing. Fortunately, global renewable energy use is also growing incredibly rapidly.
Which problem seems more tractable? Because reality has already proven it: people will happily switch to clean electricity and keep using electricity. They won't voluntarily use less electricity unless they get some benefit from that - i.e. reduced expenditure, or just plain more stuff (i.e. my LED lights consume a fraction of the power of my previous halogens, but are brighter and I have more of them and also can change light color on a schedule).
