ProSuffizienz - Reduction of energy consumption of prosumers
Data collection, analysis and visualisation to support sufficiency in prosumer households taking into account sector coupling

With a PV system on the roof, homeowners become prosumers and can generate their own final energy from renewable sources. At the same time, heating (electric heat pump) and mobility (e-car) become new, significant electricity applications in the household. To avoid rebound effects, prosumers must also minimize their absolute energy consumption (sufficiency).
In the project, electricity consumption analyses will be carried out in approx. 100 such prosumer households in a one-year field test. From this, strategies, information and a new narrative for an efficient and sufficient use of energy for prosumer households will be derived and prepared for energy consultants, system planners, companies and prosumers in a target group-specific manner. A "Prosumer Stromspiegel" will be developed to enable prosumers to use energy efficiently and sufficiently.
Electricity usage check
The electricity usage check is an online tool that was developed and trialled as part of the project with the participating households in the field test. The check gives you more transparency about the most important electricity consumption in your household and compares it with statistical averages for households of your size. You will need about 10 minutes to complete the necessary entries. At the end of the check you will find out
- how your electricity consumption is rated in a nationwide comparison
- which appliances consume a significant amount of electricity
- which appliances have a comparatively low savings potential
No personal data is collected in the electricity usage check. Data that you enter will not be saved or processed after the check has been completed.
