Table 12 Preferences regarding sustainability principles

F21

Sustainability was mainly expressed as applying renewable energy conversion, using energy efficiently, and saving energy.

Hence, in general, all three strong sustainability principles were present.

F22

Optimization and saving were clearly present in the end-use sectors. However, they were only partially present in the mobility sector and the other energy system stages.

The strategy of setting limits and refraining from the use of energy without the advantage of saving something for other purposes could not be clearly identified. Energy consumption habits were in the process of adaption, but aiming at a radical change could not be observed.

F23

Regarding aspects of sufficiency aside from saving, only the consideration of rational energy use could clearly be observed in the context of using fossil fuels for power generation, energy consumption in buildings, public illumination, or individual motorized mobility.

F24

Aspects with a potentially stronger impact in terms of sufficiency than saving such as switching off, limiting or avoiding were weakly addressed.

Almost no S3/S4 for x1/3/4/6

F25

Although aspects of consistency referring to regeneration that are particularly associated with renewable energies were present in MCAPs, energy supply contracts based on renewable sources were weakly addressed and not clearly linked to the majority of societal subsystems.

Saving energy for the benefit of switching to renewable energy contracts did not appear to be the preferred strategy.

F26

Aspects of sufficiency and efficiency were considered for heating of buildings. This does not apply to aspects of consistency.

A full shift to renewable energies in the heating sector was not observed.
