Interesting that the monitor and TV were both guilty - the 0.5W figure is pertinent. There's an EC directive that requires TVs to use <0.5 watts in standby, I expect it applies to the monitor too. But it seems that can be undermined by smart features or, probably, quick-start type features.Simple job for me today, been using energy monitoring plugs around the house to see what's using the most electricity and where I can save any.
Had two in my bedroom for the last week, one monitoring my bedroom TV (Sony KD-49XH9505), AP and Air Purifier and the other monitoring my computer, monitor (Alienware AW3418DW), Alexa and cordless phone.
Power usage for my computer, monitor, Alexa and phone was around 24w when my computer and monitor were turned off. After playing with a load of sleep state and USB settings in my BIOS, I realised my monitor was using 20w in standby and 19w when it was switched off. Turning the Power Saving settings on in the menu do nothing when it's switched on, or in standby, but drop the usage to 0.5w when switched off.
The power usage for my TV, AP and Air Purifier was 30w when the TV was in standby. The Air Purifier uses 1w and the AP 4w so the TV was eating 25w of electricity. Read up about it and it was the built in Google Assistant which after disabling, also dropped the standby usage to 0.5w.
Probably saved me north of 300kWh's a year for equipment that's turned off/in standby.
