Abstract:

This paper presents a multiple discrete-continuous extreme value model (MDCEV) of energy savings. The model predicts household decisions where to reduce CO2 emissions if they were forced to do so. The model's approach is to include all sectors of energy consumption such as private transport, housing, meat consumption and air travel. The hypothesis is that if households view all energy consumption as part of one overall budget, trade-offs between energy sectors are possible and can be modeled. The data base for the model was established with a survey among Swiss homeowners who have at least one car. In the survey the Priority Evaluator method was implemented in a web application with which the participants interactively reduced their CO2 output to a predefined goal. The MDCEV chooses multiple alternatives a household considers to reduce CO2 output and allocates the percentage of the overall reduction of to the chosen alternative. Estimation results show that installing new heating systems are preferred over refurbishment of roof and façade, an effect that is even greater for higher income levels. Females and higher income households are more likely to buy a more efficient car. Households living in municipalities with better public transport accessibility are more likely to reduce annual mileage traveled. The paper also includes an assessment of the model performance analyzing the residuals. The conclusion of the paper is that the hypothesis of one overall energy budget could not be supported.
