I don't know, but I hope the efforts to drive application-level power management somehow lead to power management improvements when using gnome on a laptop as well.
For reference, macOS introduced some APIs intended to improve power management around 2016 when the fanless usb-c MacBook Air came out.
On the software side of things, for something like decade now macOS has also surfaced which programs are egregiously power hungry to the user. The most visible way is in the battery menubar item, and in the most extreme cases it'll even show a notification. Similarly Safari tells users when sites are being too voracious.
I think this sort of thing is probably more effective than many believe at helping curb lackadaisical attitudes towards resource consumption among devs, with how it turns users into squeaky wheels.
