Ex-Post Analysis of Energy Demand in the Swiss Service Sector
Together with Prognos and Infras, we regularly carry out an ex-post analysis of energy demand in the Swiss service sector on behalf of the Swiss Federal Office of Energy (SFOE).
Energy consumption by use
The ex-post analysis examines the purposes for which domestic end energy was consumed between 2000 and 2023 and how energy consumption in the private household sector developed with changed determining factors. We ascertain the various uses with the help of a bottom-up model. This enables us to record specific consumption components and their interaction individually.
Energy consumption by determining factor
The determining factors for the measurement of end energy consumption are constantly changing. The following determining factors are taken into account: the growth of the average resident population, energy reference area and gross domestic product, the development of energy prices and climatic warming over the period 2000 to 2023. The differently changing sectors are compared with each other.
As a continuation of this ex-post analysis, Prognos, Infras and TEP Energy examined the uses of domestic energy for the years 2000 – 2022 in the 2022 ex-post analysis, as well as for the years 2000 - 2023 in the 2023 ex-post analysis.
