Abstract

EURECO project allowed to measure during one month, the electricity consumption of the main end-uses in 400 households of four European countries.

This study gathers the most relevant information available today in Europe, concerning electricity consumption in the residential sector. The consumption and load curves of each domestic appliance types are depicted. This study brings two major contributions to the knowledge of electricity consumption in the residential sector, thanks to:

  • the use of a new type of measuring device that monitors the consumption of any light source,
  • a new approach which determine the total household standby characteristics by a global measurement.

This study enabled to quantify the potential electricity saving that could be reached by substituting efficient appliances for existing ones. We shall remember that:

  • 1 000 to 1 200 kWh/year could be saved depending on the country, that is 150 to 180 TWh/year at the EC scale, standby-powers represent the first source of potential electricity saving, neck to neck with cold production,
  • the replacement of 7 to 10% of the most consuming cold appliances would allow to reach 30% of the potential energy saving of this end-use,
  • the replacement of the five most electricity consuming light bulbs in each household would allow to reach 80% of the total potential saving for lighting.

This study is first and foremost a significant information source for all the parties involved in DSM in the residential sector, but it also includes many elements that could inspire the national and European DSM policies.
