Analyses of Swiss energy use

The Swiss Federal Office of Energy (SFOE) has been conducting regular analyses of the changes in energy consumption since the beginning of the 1990s. For several years now, Prognos has taken the lead on this analysis.
The primary task of the ex-post analysis is to break down the different sets of causes for the development in energy consumption, according to energy source and sector. Determining factors such as weather conditions, economic growth, population development, production volumes, energy reference areas, energy prices, technical advances and political measures are all taken into consideration.
A further task is to examine energy consumption according to use. Here, which applications use which energy sources and the quantities employed are outlined, as well as how this energy use has changed over time. Heating, hot water, process heating, mobility, drives and processes, lighting, and ICT are all differentiated as end uses, among others.
In the context of the sectoral ex-post analysis, the household, services, industry, and transport sectors are examined using bottom-up models, with varying levels of disaggregation, which structure energy consumption in terms of energy source and application.
The bottom-up models in question are continuous annual models. This means that the total annual consumption changes result directly from the models. The effects of the individual sets of causes are fundamentally calculated in terms of a linear approximation. An influencing factor between the years tn and tn+1 is changed while keeping all other parameters constant. The resulting change in consumption, En+1–En, quantifies the effect. For each factor, the team specifies the influence in each respective year.

Latest update: 30.11.2023
Final energy consumption in Switzerland for the year 2022 was around 4 percent less than in the year 2021. Mobility (32 percent) accounted for the largest share.
Swiss energy consumption in the last 15 years has been slightly reduced. Technological progress and policy intervention played a central role, as shown by the analysis conducted by Prognos, TEP and Infras.

The energy transition is still lagging behind its goals – such are the findings of our 12th Monitoring Report. In two of the four areas, the lights remain on red.
What is the status of the energy transition in Germany? Since 2012, Prognos has been monitoring the energy transition in Bavaria and Germany on behalf of the vbw.
Environmental organisations have tasked Prognos with adapting selected assumptions from the Federal Ministry of Transport and Digital Infrastructure transport forecasts to facilitate climate-friendly transport development.
What will Switzerland look like in the future? A welfare state in a fair world or an energy guzzler in fortress Europe? We examine the potential impacts of different scenarios on greenhouse gas emissions.
Our study for the vbw compares electricity and gas prices for industry worldwide and provides a price development outlook up to the year 2030.
How much LNG can it be? Prognos prepared two studies for the German government's Science Platform for Climate Protection (WPKS) to address this question.
A study for the Bertelsmann Stiftung shows which climate policy measures can best support the switch to low-emission production processes.
One potential building block: the Federal Network Agency commissioned Prognos to conduct a study that can support the necessary assessment in the case of gas shortages.
How can existing buildings become climate-neutral by 2045? On behalf of the BMWK, we developed scenarios and measures.
Prognos is one of the oldest economic research centres in Europe. Founded at the University of Basel, Prognos experts have been conducting research for a wide range of clients from the public and private sectors since 1959 – politically independent, scientifically sound.
