In order to implement Energy Strategy 2050, the entire country must save electricity. It is not only companies who are called upon to take action here, but rather also families, couples, flat-sharing communities and those living alone. So-called smart meters that can precisely measure and display a household’s electricity consumption could help here. The assumption is that those who know more about their consumption also save more. However, the research conducted to date has shown that smart meters only lead to minor savings.
Could this have something to do with what information the users receive? Researchers from the University of Lausanne looked at this question. They wanted to know which consumption information is most likely to motivate people to save electricity. As part of an experiment, more than 1,000 private households in Germany were equipped with a smartphone app that provided occupants with feedback on their electricity consumption.
The households were assigned at random into five groups that received different information. There was also a control group comprising households that did not participate in the experiment but whose consumption was nevertheless measured using smart metres. Possible differences relative to this group should show what kind of feedback has what impact.
