> Apparently the average American residential electricity use is 10,791 kwh/year, which is ~1,231 watts, whereas the average British home is only 2,700 kwh/year which is ~308 watts. I had no idea that the difference was so large. They main reason is that US has a higher percentage of all-electric homes. The average medium sized UK home uses 2700 kWh/year of electricity and 11500 kWh/year of gas. See that table in your second link. What you want to compare is average household energy use excluding transportation. For the UK the numbers in your link give 9400 kWh/year for 1-2 people in a flat or 1-bedroom house, 14200 kWh/year for 2-3 people in a 3-bedroom house, and 21100 kWh/year for 4-5 people in a 5-bedroom house. I'll leave it to someone else to find out how those are distributed to work out the average for the UK as a whole. For the US, in 2011 [1], annual usage was 108 MBTU for single family detached houses, 89 MBTU for single family attached houses, and 54 MBTU for multi-family housing. In kWh that's 31700 kWh, 26100 kWh, and 15800 kWh. I'll leave it for someone else to find the distribution so those can be combined, and to find later data. Almost all searches for household energy US of US households just return electricity usage and the 2011 document was the only thing I found that gave what I was looking for.
