Your desktop PC uses almost 2kWh per day? Do you ever turn it off or put it to sleep?

Mine runs 24x7 except for the screens, they sleep after 10 minutes of idle time. CPU sleep is too much of a crapshoot, I'd rather spend a few dollars on power than have to spend time getting my work environment restarted and back into a productive state.

10 for the display, 20 minutes for deep hibernation. I reboot around once a week. Never had issues with it waking up.

Not turning off your pc is pretty bananas. How long is your cold boot?

Not long, maybe a minute including POST and all the pre-boot stuff. But sitting down and having everything exactly the way I left it gets me back into "flow" much quicker than having to start up all my applications and get them back to where I left off. Yes in theory hibernate/sleep does this and it usually does but sometimes there are weird quirks, in particular ssh sessions, remote filesystem mounts, and other types of stateful connections are usually borked, and I'd rather not worry about any of it.

It's absurd how broken sleep is on most machines. Macbooks are the only devices I've observed to correctly resume.

Mine does not correctly resume.

It forgets about any peripheral plugged into it. And the only way to fix it is to reboot.

Yeah...that's how I've usually done things, too. I'm starting to reconsider, and trying to flip off a power strip with PC/TV/etc before bed.

It is inconvenient to lose state. Web browsers can happily spring back up with previously-opened tabs, but you lose a sense of continuity with other apps, shell history, etc.

General question to the community, what's the state of window manager snapshotting these days? I've been able to snapshot/restore non-GUI process trees with CRIU, but I haven't been able to make it work with an X11|Wayland server. I don't think it snapshots GPU state.

Maybe it'd be a better idea to do everything in VMs, and save/load them across reboots?

6-7h a day when I'm sleeping.
