Towards a bright future? Household use of electric light: A microlevel study

Abstract

This paper addresses the problem of energy saving in the residential sector and its relation to behavior. However, we know little about the mechanisms explaining consumption and use. The aim is to explore the behavioral elements behind patterns of use, so that consumption can be explained and saving possibilities identified. The study is based on detailed, metered data from an ongoing monitoring study. A larger sample from that study made testing of two hypotheses possible. Yet, many factors remain hidden and must be traced among the habits of households. The major part of the article is devoted to an exploration into what other variables are at work. This was done by studying the electricity consumption of seven households closely. Here, different sources of information from each household were combined: detailed, metered data for each lamp or fixture; data from interviews regarding habits; and observations of natural light and lighting equipment at visits. This information from combined sources was used to detect meanings of use and relationships with consumption. What has been found here must be translated to measurable variables and tested on representative samples of populations. This study offers information on these variables identified and how to interpret them. © 2008 Elsevier Ltd. All rights reserved.
