The technological development in the last 50 years has been rapid, and it is getting faster and faster.
On the contrary, since the beginning of space travel, people have tried to increase the efficiency of photovoltaics and ultimately failed. The e-car hype happened decades ago with exactly the same problem, only today the batteries are better.
Our heating systems have never had such a short lifespan; poor technology like air heat pumps is completely excluded, as it only pays off politically motivated, because the primary energy factor was shifted without a physical reason.
Energy-plus houses / KfW40+ is pure politics; nothing pays off for the end consumer, only the industry benefits.
75% of the heat protection verifications are still not calculated according to DIN 18599, so progress is very, very slow.
