Good stuff, I think everyone needs to take such action.
Another good one is putting your PC to hibernate/sleep when not used, and making sure Balanced power mode is on. This should allow it to lower power to CPU when not needing extra horse power.
I used to always set mine to max performance, and just leave it running for hours on end when not using it!
I switch my PC off when not in use anyway, so not really much to save there unless I decide to do a major downgrade (which isn't happening ).
One thing I do need to start is turning my work laptop off at the end of the day. Been putting that off as I often have several VS and SSMS windows open with work in progress, and it doesn't seem to like hibernating for some reason
My idle usage overnight when everything* is switched off is still at ~140w though, and the laptop is probably close to half of that. 70w doesn't sound like a lot - 2.5p/hour at 35p/kWh, but do the maths and it's ~40p/day (for the 16 hours I'm not working) or ~£12/month!
Looking at electric blankets for us and our 10 year old, but we have a 2 year old as well who can't really have one, so there's a limit to how low we can drop the temperature :s
* overnight we still have actively powered:
Router
Alarm
Boiler
Smart thermostat & bridge
A couple of nightlights for the kids (LED bulbs)
Security lights (LED bulbs)
Fridge Freezer
Work laptop
Phone chargers
Along with a load of stuff left on standby - I really need to take a wander around the house at night and start turning things off, even if I can get that down to say 50w that would still save ~£10/month
