... So, no, you WISH upon a star the numbers are different.
Typical.
Heat source was not listed. That is an average for ALL homes in their respective countries, be they straight electric, HVAC, or Natural gas heated.
If you use straight electric heat, without a heat pump, there is no way in this world you will heat an average sized home on 24kWh/day. Try Several times higher.
I used to have one of those homes using straight electric in a VERY mild climate region of the USA(Western Washington State) where the Temperatures barely went below freezing during the winter--> Average is around 5-->10C. We were running hundreds of kWh/day. Knew the house had problems and instantly went to work.
#1 Instantly threw 1/3 of a meter of insulation into the attic+old compacted insulation for ~1/2m thick, drilled holes into the walls(15cm) and refilled the walls with insulation as the old insulation had compacted down.
#2 Sealed all light fixtures, plumbing holes and assorted openings into the attic. Ripped open the roof peak to vent for summer
#2, ripped off the aluminum old single pane windows(couldn't even open the windows anyways) and installed double paned Wood Anderson windows and resealed everything. Even did a bag test on several of them and seals were perfect when new anyways.
#3 Ripped off the sliding door which was broken anyways(I did mention I got a screaming deal on the house yes?) and replaced with a non sliding swing door which actually had seals and less glass. Front door I added new seals in grooves I cut into the door making it air tight. Got to the Garage doors later.
#4 Added a valve block to exhaust fans as well(later though)
#5 Fireplace Chimney was blocked initially just to get a reading.
Still had Electric Heat(hot water included). kWh/day dropped down to around 40-->50kWh/day(winter) in a NON Freezing climate in a ~1200 sqft(120m^2) home using electric only. 1 refrigerator only and that was back when everyone was using incandescent lights. There is no way in this world an average household residence would be lower than this unless you share common walls with your neighbors.
To achieve lower numbers than this with ONLY electric heat, you would have to double the thickness of the walls for double insulation at minimum or build a South facing Greenhouse on front of your home and live in a VERY cold home or NEVER go home, warm yourself on your companies $$$, or resteraunts(pay big $$$ for food while pretending you are "helping the environment") and do not have a Family...
I was not going to do that.
Sold the home, now doing roughly the same on the home I am in.
