I would be nice to have a quantitative grip on how much energy is lost.
EarthTrends: Data Tables - Energy and Resources
Energy and Resources DATA TABLES Select a data table from the list. Energy Consumption by Sector 2005
The "residential" category should give some clues. Though the tables are in total energy/country and then divided in percentage of that total. So to compare one would need to get the absolute number for residential and divide by population to get residential/capita. And it is getting late in Sweden so I will not get the spreadsheet out now.
