This chapter explores the underpinning dimensions of energy-using practices among an affluent social group in Geneva, or households who self-identify as being part of the expatriate population. We demonstrate how people can be locked into certain consumption practices by their physical possessions, a form of material lock-in, but also by social status and power dynamics, what we term social lock-in. Much of this has to do with expectations around social norms, or how normality is constructed within this social group and across different consumption spaces, and the critical role of norms in holding practices together over time. Opportunities for destabilizing practices and challenging expectations around energy consumption are discussed, including the role of demonstration sites, the value of time and the significance of social networks.
