Electric appliances are an indispensable part of a household, and through their sheer number contribute substantially to its electricity consumption. This paper explores potential reductions in residential appliance electricity consumption in the Netherlands with smart meters, combining two perspectives: a sociotechnical approach and a bottom up engineering approach. The first is used to shed light on particular factors that affect household electricity consumption, while with the second policy scenarios are explored regarding efficiency, smart meter diffusion and consumer behaviour. Simulation results indicate the extent of potential electricity consumption reductions.Keywords: households, electricity consumption, system dynamics
IntroductionHousehold energy consumption is important, whether it comes from heating, lighting, leisure activities, or cooking. In the Netherlands, the housing sector constitutes approximately 41% of the total national final energy consumption (Guerra Santin et al., 2009). Developing and implementing policies in order to reduce it in line with European guidelines for 2020, is a significant challenge (Klunder, 2005; Beerepoot, 2007). Previous work has shown that it is not easy to overcome the inertia of the housing stock and improve its energy efficiency through renovation, demolition of old houses and raising energy standards of new constructions (Yucel, 2013).The present paper presents work done as part of a project funded by the Netherlands Organisation for Scientific Research (NWO) that looks at the Dutch energy transition with a focus on the built environment. Numerous studies have looked at household heating and cooling energy consumption (for a review see Swan and Ugursal, 2009; Kavgic et al., 2010; Lee and Yao, 2013), but very few concern the Netherlands, or look at appliance electricity consumption which is a However, household electricity consumption is not just determined by appliance specifications.Consumption in identical homes, even in low-energy dwellings, can easily differ by a factor of two or more, depending on occupant behaviour (Darby, 2006). Hence, technical and physical improvements in household efficiency are not enough to warrant reduced electricity consumption. This is a sociotechnical issue (Grin et al., 2010), in the sense that innovation and technology policies, as well as electricity supply and consumer behaviour are all intricately connected. Therefore, policies aiming to reduce electricity consumption must have a demand side component aiming at reducing electricity demand, as well as a supply-technical component aiming at improving the energy efficiency of appliances (Harmsen and Graus, 2013; Antal and van den Bergh, 2014). Consequently, the analysis of electricity consumption in this paper is informed by drawing insights from a sociotechnical perspective.To the extent that changing consumer behaviour and energy consumption practices lead to real and persistent energy savings, they will contribute towards achieving emission policy goals as well...
