Better understand household consumption and the resulting direct / indirect energy consumption

Consider two constraints on consumption:

◦ Monetary budget

◦ Time budget

Take into account household heterogeneity

◦ Income

◦ Household composition

◦ Housing type

Household Expenditure Survey (INSEE, France, 2010-2011)

Time Use Survey (INSEE, France, 2009-2010)

National Housing Survey (INSEE, France, 2006)

National Travel survey (INSEE, France, 2008)

Electricity use survey (EDF R&D, France, 2013)

2 main data sets:

3 accessory data sets:

We estimated time use for each person of the household expenditure survey and then reconstructed time use for each household

We analysed time use and expenditure for 13 activities:

Energy expenditure, travel time and travel expenditure were distributed to the activities using the accessory data sets

Using both expenditure and time use data allows to describe household consumption in a more realistic way

This description, combined with a CGE model, will enable us to analyse possible changes in direct and indirect energy use resulting from changes in household behaviour.
