Our mission

On behalf of the Energy Agency for Electrical Appliances (eae), an initiative of the electrical industry associations, Prognos annually examines the development of the efficiency of newly sold electrical appliances and the appliance stock in Switzerland. The efficiency analysis is intended to shed light on the impact of changes in purchasing behaviours and supply on the energy consumption of electrical appliances in Switzerland.

The analysis includes both “white goods” such as refrigerators, freezers, and washing machines, as well as various information and communication equipment items, including computers, monitors, and routers. In addition to efficiency development and appliance sales, the team also considers the development of equipment size (e. g., diagonal screen measurement, cooling volume).

Prognos’ evaluations serve as the basis for the annual eae report for the Swiss Federal Office of Energy (BFE) and are incorporated into the EnergieSchweiz programme’s planning of measures.

How we proceed

For the purpose of the annual analysis, the project team uses data collected by the FEA and SWICO industry associations as well as eae data. On the basis of these annual surveys of appliances sold by category and energy efficiency class, as well as assumptions about the lifetime of the appliances, the team uses cohort models to calculate the energy consumption of the device and appliance stock. The development of energy consumption can thus be determined continuously to a high level of detail. Comparisons with previous years – both in terms of new devices and appliances sold and the energy consumption of the equipment stock – make it possible to assess efficiency progress.

Ex-post analysis of Swiss energy consumption in 2024

2025
| Project update

The analysis for the Federal Office of Energy shows that final energy consumption has fallen significantly since 2000, mainly thanks to savings in space and process heating. At the same time, demand has risen in areas such as electrical appliances and building services. Consumption has not changed significantly since 2020.
