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?)


Stop services you don’t need. Doesn’t matter the distro.
You can also turn off devices right at the bus.
Powertop is a great tool.
