There are some slight changes for big consumers. (e.g. public swimming pools reduced temperature) Also people are told to watch their consume (which happens automatically when gasprices increase, my gasprices per kWh are doubled) And last one is a big storage infrastructure (old salt caverns) and the hope that the winter won't be that hard. On the long term germany tries to convert the system more to renewables, especially in the heating sector (hydrogen or heat pumps, but this will take some time)
