Materials changing the performance of the household energy consumption practices

Abstract

Materials are an essential part of social practices, their performance and sustainability. However, there are different views on the role of materials in practices and the agency they induce in relation to humans. The purpose of this research is to examine the agency of material in the household energy consumption practices. To this end, we analyse consumer narratives (n = 25) and interviews (n = 30) on daily home practices. Based on practice-theoretical analysis, we demonstrate that materials can change the performance of a practice in three main ways: by delaying the performance of the practice, shaping its performance, or creating a new practice. Furthermore, by comparing the material agency from human-centric and posthumanist practice theoretical approaches, we pinpoint the variability on the views on material contribution to practices and their sustainability. We show how sustainability is determined by the materiality of the practice, its connection to other practices, and people’s reactions to the disruption caused by the material.
