The trouble you mention over refridgerator electricity consumption sounds about right.
I tested a neighbors fridge with a Kill-A-Watt meter after he complained about his bill being to high and got about 1.1KWH/day. His is medium sized and had the door seals replaced by the landlord before he moved in.
The US govt estimates 1.35kwh/day use for a modern fridge. If Seimens claims theirs uses .75kwh/day, they are either lying or never open the door. To get .75/day you would have to have a cool well ventilated location (no real kitchen does, you cook in that room and the fridge is usually shoved up against a wall) and the food would have to be sealed so no dehydration occurs. Removing water from food costs energy.
In the US we drink our tea with sugar over ice. The English drink tea hot with milk like we drink coffee. If I make tea, I make it super strong (little water and lots of tea) and then let it cool to room temp before putting it in the fridge. When I want a cup, I dilute the concentrate with cold water from the fridge and add sugar. That saves time and energy.
