AbstractIn this paper, we analyze the level of efficiency in the use of electricity in the European residential sector relying on a cross-sectional data set comprised of 1375 households located in Italy, the Netherlands, and Switzerland and observed in 2016. To do this, we estimate an electricity demand frontier function using a stochastic frontier approach. The empirical results show that the residential sector in these three European countries could save approximately 20% of its total electricity consumption on average if it improves the level of efficiency in the use of electricity. These figures are in line with recent studies for Switzerland and for the US residential sector. Moreover, we link energy efficiency to energy-related financial literacy. We find that while energy-relevant knowledge per se does not play a significant role, stronger cognitive abilities are associated with higher levels of energy efficiency.

We estimate the short- and long-run elasticities of electricity demand in Switzerland using a dynamic model of residential electricity consumption incorporating a correction introduced by Kiviet. We find that the short-run elasticity of residential demand for electricity in Switzerland is around −0.3 while the long-run elasticity is around −0.6. Our estimates indicate that pricing policy as a plan for energy strategy may have a moderate impact on residential customers in the short run but will have a stronger influence in the long-run. In view of the recent proposal in Switzerland to introduce a tax on electricity as part of its energy strategy plan, an increase in the price of electricity may result in a moderate decrease in electricity consumption.

Abstract Improving efficiency in the use of energy is an important goal for many nations since end-use energy efficiency can help to reduce CO 2 emissions. Furthermore, since the residential sector in industrialised countries requires around one third of the end-use electricity, it is important for policy makers to estimate the scope for electricity saving in households to reduce electricity consumption by using appropriate steering mechanisms. We estimate the level of technical efficiency in the use of electricity using data from a Swiss household survey. We find an average inefficiency in electricity use by Swiss households of around 20 to 25%. Bottom-up economic-engineering models estimate the potential in Switzerland to be around 15%. In this paper we use a sub-vector input distance frontier function based on economic foundations. Our estimates lie at the upper end of the electricity saving potential estimated by the afore-mentioned economic-engineering approach.
