Not a lot really. I've arranged so machines I left running 24/7 previously are off a lot of the time and that I can power them on remotely if needed. One of those boxes used to host backups, those have moved to a single SSD (lower power) in the low-power box that acts as my router and the external copies are still on RAIDed drives. One of the things powered off is the media array (its RAIDed volume is where those backups lived, they still do but are only updated when it is on obviously). I've toyed with the idea of moving more out external hosts, but with their prices going up too and announcements that for the next while UK residential fuel prices will be capped I need to find a little time to run some calculations to see if that would save anything and if that anything is enough to be worth the hassle. I might have the heating on less (mainly by setting the thermostat defaults lower, partly by hitting the boost button less) over winter.

Maybe I'll finally replace the old oven. Partly because a new one might be more efficient, though mainly because I've been thinking of doing that for ages as it is ancient and possibly on its last legs.

Might get the gas fire that hasn't been turned on for years serviced, so I can heat just the living room at times instead of the whole flat via central heating, though without taking time to work out the maths I don't know if that is likely to make much difference to a small place like mine.

Though I do really have to do much, having the luxury of being comfortable enough that the extra cost is only an irritation, not a life changing problem that it might be for people who are struggling financially already, and my place is pretty well insulated.

I looked into things like that before, but you really need to look at your overall consumption first. For me, it would be like removing a crumb (PC) while the loaf of bread (heating) is still there. The PC is a rounding error compared to the heating, so I would be better off focusing on insulation and preventing heat loss.

I am 100% electric, though.
