Not sure I understand that comparison, what does comparing a base load while being away from home for 24 hours have to do with work from home? Unless when you go to work it means you always stay out the home for 24 hours? Surely you can't count power to run hot water for showers, lighting in the morning/evening, power for breakfasts, first brews, charging phones, power used by opening fridges etc in the morning/evening, TV, gaming, DIY <insert whatever you do in the evenings> against your WFH usage as it happens regardless of your work destination?
I do either work from home or I'm away for 3 days generally a week. However the above I didn't take cooking or showering and a day I go into office I have my first and last coffee there, I don't drink them first thing in morning or after I finish work.
Charging phones, tablets is 100% at work so don't charge any of that at home. But the point was you suggested that WFH is only 0.6kWh. It's not because I'd only do 3hrs work a day at that.
To note that even if I had a laptop with say a 3080 to do my work the power drawer is more like 150watt. That is a much larger amount to the claimed 30watt. A laptop ideals around that or for basic office or Web browsing.
I ignored anything with regard to cooking and showering as that would be same if I came back from work or just WFH.
But yes I also have two days home, one day after work for about 3hrs before I'm asleep after I get back from office and the other is the Sunday evening after saying bye toy boys for the weekend till I see the again Tuesday. So those two days I am home otherwise only on the Monday night am I generally cooking at home anyways compared to any other day I'm somewhere else eating.
But even if all the other stuff is the base amount the WFH is still an additional 2kWh and then everything else whatever that adds up is on average 2kWh. So days I am out completely is about 1.56kWh. Then I use about 0.5kWh for the odd things like boiler on for hot water or the odd use of a microwave or whatever.
This week:
Monday 2.6kWh as was home evening
Tuesday 2kWh as out 24hrs
Wednesday 4.2kWh WFH (short day as went to gig that evening)
Thursday 4.6kWh WFH
Friday, don't know as will tell me tomorrow on account. But I did WFH in say but left for dad's 65th bday for evening and not back till Sunday evening now.
Ad example so yeah WFH doubles my general usage otherwise.
