This still works for Apple Silicon based Macs: [Wayback/Archive] How can I tell what wattage my MacBook Pr… – Apple Community
TL;DR:
Note that “System Report…” starts the “System Information.app” (how cool would naming consistency be…)

The last one does not work on my Apple Silicon machine, the first two work fine.
For Preview, you have to Force Quit it then start it (so it re-opens all the previous files) to take effect.
I needed this, because I

With the permission of Adobe Systems Inc., the Computer History Museum is pleased to make available, for non-commercial use, the source code to the 1990 version 1.0.1 of Photoshop. All the code is here with the exception of the MacApp applications library that was licensed from Apple. There are 179 files in the zipped folder, comprising about 128,000 lines of mostly uncommented but well-structured code. By line count, about 75% of the code is in Pascal, about 15% is in 68000 assembler language, and the rest is data of various sorts.

When I have an external monitor connected to my 2015 era Retina MacBook Pro machines, I wanted some apps to appear on the laptop screen and others on the external one.
That was harder than I hoped for as no single solution works in all cases.
What I do now is to make sure the icon bar is on the monitor where I want applications to open. Not perfect, but works for most cases.
Here are some links that helped me:

TL;DR: it is impossible on a Mac to accurately measure power usage by attached USB devices. Only a general indication is possible, but it is unreliable.
