That is an interesting take. Can I save a lot of battery by choosing 1080 instead of 2/4k for laptops in general? You don't really need 2k for prose text or programming anyway.

Yes. What your link states is that running a 4k monitor at 1080p won’t save you power (it will, but via gpu, not monitor draw).
A 1080p monitor will require substantially less power than a 4k monitor, all other factors held equal.
