My NAS/home server takes about 180 kWH/year, or 20W on average (costs me about 5 Euro/month). This feels like a lot to me and makes up a good chunk of my total energy usage.
What I did to optimize it is mostly select a “low-power” x86 platform, and limit the number of disks. I also decided not to use TrueNAS because it couldn’t let the disks from going to sleep.
The machine hosts 10 TB of usable storage (+RAID 1), syncthing, immich, file server, Influx DB, Grafana, and a few other services.

That’s the one thing I don’t like about Truenas. It technically can spin down disks, but there’s no way to force them. You can set the idle timer to 5 minutes, but then it constantly spins them back up again. Now I just power the entire system down with home assistant outside of the usage hours and I can power it up again with home assistant using wake on Lan. A bit goofy, but it works for me
