Going Beyond Tradition: Estimating Residential Electricity Demand Using an Appliance Index and Energy Services

In this paper we estimate the long- and short-run price elasticities of residential electricity consumption in Switzerland from a household survey by constructing an index of the stock of household appliances as well as by using energy services. We create the index by aggregating the information on the major household appliances. The index is used to estimate the impact of appliances on residential electricity demand. Furthermore, we also use energy services to estimate the electricity demand. We adopt an instrumental variables approach to obtain consistent estimates of the price elasticity to account for potential endogeneity concerns with the average price as well as the appliance index. Our results suggest that the price elasticity is around -0.6. We conclude that Swiss households are price inelastic in electricity prices. This can be used for policy makers as well as by utility companies to design pricing instruments to modify electricity consumption. We also find that estimates of the electricity demand when we substitute the usual residential characteristics with energy services are quite comparable.

The role of energy and investment literacy for residential electricity demand and end-use efficiency

This paper estimates the level of transient and persistent efficiency in the use of electricity in Swiss households using the generalized true random effects model (GTREM). A panel dataset of 1,994 Swiss households from 2010 to 2014 collected via a household survey is used to estimate an electricity demand frontier function. We further investigate whether energy and investment literacy have an influence on the household electricity consumption. The results show significant inefficiencies in the use of electricity among Swiss households, both transient (11%) and persistent (22%). We note that the high persistent inefficiency is indicative of structural problems faced by households and systematic behavioral shortcomings in residential electricity consumption. These results indicate a considerable potential for electricity savings and thus reaching the reduction targets defined by the Swiss federal council as part of the Energy Strategy 2050, wherein end-use efficiency improvement is one of the main pillars. The results support a positive role of energy and, in particular, investment literacy in reducing household electricity consumption. Policies targeting an improvement of these attributes could help to improve efficiency in the use of energy within households.
