- Many people install photovoltaics even without an obligation.
- Heat pumps as well. Pellets, wood, gas are rather unusual here, also in many construction service descriptions.
- The energy saving ordinance is also becoming increasingly unusual.

When was the last energy saving ordinance house with gas discussed here?
Minimum wage affects everything, not just the house. Food, services, crafts, industry. Almost all sectors will have wage increases.
