For a long time economic literature focused on the negative environmental effects from production processes. Countering this is the focus of this investigation, namely research into the demand by private households for climate relevant energy. In order to be fair to the complexity of the energy demands of private households, time series data as well as cross sectional data will be used. Furthermore specific data sets will be developed to establish consistent parameters of reaction for the most important factors. The energy demand of private households will also be represented in a model for total consumer demand, in order to capture the feedback effect on demand. The results bring into doubt whether policies which are aimed at reducing the energy demand of private households can solely be based on improvements in technological efficiency.
