Which distros are energy efficient? I have a capable desktop, and I mean to push it, but I don’t want to be using energy if it’s not necessary. I’m not looking to rescue an old laptop, for example.
I hear CachyOS is fast. Does that translate to energy efficient?
(Does the OS even matter that much for efficiency?)


I have Ubuntu running with a sound bar and monitor that only pulls 40 watts. My processor is one of those vanilla box mini computers…GMKTech. I’m able to run it off a 1 kwh solar power station and it lasts a laughably long time. How much more efficiency do you need? I have fans that use more power than my desktop.
I don’t know how your monitor is this efficient, mine consumes around that exact amount (40 watts) according to “displayspecifications.com”.
Anyways, with my laptop eDP panel instead (driven by sway), external keyboard, external mouse, I have running:
Let’s look at
upower -d:energy: 35,926 Wh energy-empty: 0 Wh energy-full: 35,926 Wh energy-full-design: 53,049 Wh (...) energy-rate: 5,64 W time to empty: 6,3 hours (...) capacity: 67,7223% technology: lithium-ionroflmao (no, I don’t know why my battery is already this dead, or at least is counted as such)
EDIT: before anyone mentions how a laptop is cheating, mini PCs all have laptop CPUs/APUs anyway
