What kind of smaller use items are you talking about? And what did you optimise? I'm wanting to do the same and if I can get a 33% reduction that would be great!
a lot is specific to my household and stuff i happened to have but I'll list them.
- Turned off garage door opener, used to be on 24/7, use it once in a blue moon
- Turned off house alarm, was never given the code when i moved in
- Changed my CH pump to Proportional Pressure II from Constant Speed III
- Turned off a 4 channel aerial splitter in the loft, i don't use live TV and don't pay for a licence
- I removed a lightwave lightswitch and hub, used it once a day just to be lazy when going to bed
- My fridge is too big for us, it spends a lot of time empty so i've filled up several shelves with items (empty cooler box, 2L bottles filled with water) to stop it dumping loads of air out everytime and having to cool it down
- Removed a "sun rise" clock, stopped using it a while back and it was just there for time. I have a health band or phone i use for time anyway
- Moved my router to a diffrent location so i could get rid of a 8 port switch. Sacrificed some wifi reception for that but worst place in the house still gets 60mbps+
- We have a tv in the dining room thats never used, turned it fully off
- In my downstairs gym i turn off at the wall the tv/firestick/alexa. Gets used once a day when i exercise. I get ready to row while it boots so no lost time
- Similar in the garage i turn off the speakers/echo there when not doing work there
- I have a ton of amazon echos, maybe 10 in total. Unplugged several that were basiclly not used (eg conservatory, if you want music the kitchen one carrys through fine, 2 year old had an old echo for some reason in her room)
- Adjusted my home desk so i can turn off scanner/printer 1/printer 2/shredder on a single switch. Not used often
- Adjusted my work desk, work PC on 8 hours, and a second home PC on for 8 hours. The second home PC has been swapped out for a laptop which is saving power as it used to be a desktop with a GTX1060 and a old speaker system
- Changed the power supply on my server, its a 3800x, 64GB ram, 2TB nvme, 8x 4TB disks. It idles at around 60-70w but had a 850w PSU (used to have a gaming GPU and stuff in there). Its now got a old 360w PSU in there and is closer in the optimum efficiency band of the PSU. Both were gold rated.
- Living room has 2x 14w LED main lights. We don't use these much now while watching TV and switched over to a floor standing lamp we had which is 8w
- Made better use of house phone base stations which allowed me to remove one handset and charging station
Even though its a long list, most of it is 24/7 use things that have been removed so it doesn't impact our daily life really. I can't get much lower without really sacrificing my routines/wants. Most of the usage now i can attribute to my 2 servers and the fridge (large, cheap, inefficiency american style one), which is around 40%-50% current total usage.
