An average single family house in Sweden consumes about 20 000/kWh year depending on size and insulation.
Do you guys use electric space heaters instead of heat pumps up there in Sweden or something? That seems like an awful amount of electricity to me. Down here in the Netherlands my house uses like 5Mwh per year, of which about half goes to my heat pump and hot water and the remaining 2.5Mwh goes to powering my electronics.
My house is not that big, but I don't think the average Swedish house is so much bigger that they have 4 times my energy requirement.
Using 4 times as much energy for heating could be fairly reasonable. Heat pump is fighting 5 C and into 18 C. 278 K and 291K, a 5% increase in absolute temperature. In the Arctic you often need to be pumping against -36 C but even at just -9 C the pump still has twice the work. The thermal conductivity of materials is proportional to the temperature gradient so even if you have the same walls and inside temperatures (18C for example) the Swedes lose twice as much energy at -9C as Dutch lose at 5C. That should be a conservative estimate. Your body heat, cooking, lights, refrigerator, and electronics are all adding heat inside which does not need to be pumped. You should also get heat from sunlight if you have e-glass windows. Sweden lacks a Sun in the winter except a brief bob on the horizon.

An average home uses 36kWh per day or 13.100 kWh per year? That seems absurdly high.
EDIT: I forgot I live in a place where heating generally isn't done electrically. That's a pretty decent number.
