I only have anekdata, unfortunately. My observations: * I tried to find a contractor for some work on my house. Very few were available, none were available short-term. Most told me this is due to extreme demand for isolation measures. * Lead times on heat pumps rose to half a year, presumably also due to demand. * People dressed warmer. * The most common thermostat temperature for people around me temperature dropped from 20c to 19c. * "How to isolate" was a very common topic in most Dutch media, far more than in previous winters.
