How much energy do my household appliances use?

The annual consumption of an average family in Brussels – who cooks with gas and therefore does not heat water using electricity – is estimated at 2,812 kWh. Per category of type of appliance, this means:

  • 25.5 % is used in the kitchen
  • 27.8 % for cleaning and maintaining the home
  • 28.9 % for leisure activities
  • 17.8 % for lighting and other appliances not included in the above categories.

The table provides an overview of consumption per appliance and below you will find a complete full answer with the parameters used to estimate this consumption.

The energy used by household appliances is calculated on the basis of their capacity (expressed in watts) and the length or frequency of use.
