I think the reason is precisely this: people will not pay utility companies if they have eco houses. but it is not profitable for them. therefore, there are many laws that limit this. Alas!!!! I am glad that you live in a country where there is no such problem. How wonderful it is that you have stained glass windows and a massage chair (I really hope that you will never tell me that it broke and that you are stuck there :))))) It’s so great to go back to a cozy home in the evening, sit in that chair and have a nice relaxing massage, taking off all your daytime fatigue.
