Abstrakt

Artiklen analyserer effekten af at give on-line feedback om husholdningers samlede elforbrug. Feedback gives med SMS, e-mail og en web-side. I forsøget indgik 1452 husholdninger med nye "elektroniske" elmålere. Det blev gennemført hos Syd Energi. Husholdningerne blev tilfældigt fordelt på tre eksperimentgrupper og to kontrolgrupper, hvoraf den ene kontrolgruppe var blind i den forstand, at den ikke vidste (og aldrig vil få et vide) at den deltog i et forsøg. Der blev givet feedback i hele 2007 til medlemmer af forsøgsgrupperne. Udviklingen i elforbruget i de tre forsøgsgrupper og de to kontrolgrupper blev registreret for 2006 og 2007 og analyseret i 2008. Analysen viser en elbesparelse på op til 3%. Man skal her erindre, at der i forsøget blev anvendt eksisterende teknologi, hvorfor forsøgets driftsomkostninger var meget små.

An experiment was conducted in which 1,452 households were randomly allocated to three experimental groups and two control groups. Feedback was supplied throughout 2007 to members of the experiment groups who accepted the invitation, and data on consumption of electricity for 2006 and 2007 collected for all participants and control group members. 30{\%} of the households invited to receive feedback accepted the invitation. Results suggest that the type of feedback provided in this experiment can reduce consumption by up to 3{\%}. The feedback technology is cheap to implement and therefore likely to be cost-effective.",
