The combination of two different sets of data comprised the background for a very detailed analysis of the patterns of domestic electricity use. The first data set included over 50,000 households coupling individual electricity use with socio-economic data on household members, building size and type etc. The second data set comprised 100 households with electricity consumption for every 10 minutes during one month for each appliance and for most lamps. The detailed analysis of the use of appliances was coupled with socio-economic and building data from a questionnaire and with qualitative interviews on everyday life and electricity use in 10 households. We find that background variables such as income and age do explain some differences both of total electricity use and in the distribution on different types of end-uses. Background variables however only explain some of the variations. From the qualitative interviews we learned that the question of being a "saver" or a "spender" seemed to give some further explanation of variations, even though we found a limited correlation between the end-uses the families were most aware of from a saving perspective and the most electricity consuming appliances in the household
