I can talk only about Berlin but many furniture stores have started to switch all lights off at night. Even the Ikea sign isn't lit anymore.

I guess the take on that is, that there is no good regulation for it. If it can be one way in one city, for some of the shops, and different for other cities or other shops, then the measures/policies are not really reaching the target. Apparently one cannot rely on people doing the right thing, especially not, when they are in some kind of loosely associated group like a business, where no one feels responsible at the end. It might be a topic which needs intervention by the state to get the desired effect.

In the US industrial & large electric consumers often pay a cheaper $/Kwh price. But they also have additional peak demand surcharges.

While I'm sure there's a ton of possible places for commercial use to optimize that aren't being done yet, stores leaving signs on all night was banned by the EnSikuMaV back in August.

They should come to my city then and start fining businesses for violating that.

Covid taught us that Germany loves to pass laws that it does not enforce at all. Germans are astonishingly compliant, but it still sucks to follow the law only to enable those who don't.

Half of Germany has asthma, I guess, which is why they do not need to wear masks properly in public transport. Who would have guessed, that the pandemic brings so many health problems? The amount of asthma patients must be what they are talking about when they say "long covid". How else can we explain people's behavior?

It is really ridiculously selfish how people act here. As if one couldn't see, that they did not properly fit their mask to the back of their noses in so many cases, if they wear a mask at all. Or those people, who continuously lift their mask when breathing out ... How much must one not understand?

In absolute terms I wouldn't say that Germany is very compliant. Maybe 50% compliant in public transport, if I count the people who really wear FFP2 masks properly, as is the rule. There are even signs there and frequent announcements, that you must wear an FFP2 mask in public transport.

Compared with other countries I see, that people in Japan and South Korea have more insight and behave less selfish, more caring about the person next to them than they do in Germany. But that is merely a media impression I got from some news reports and interviews of people on the streets, which might have been highly selective. So comparatively Germany might be above average of compliance with the law, but I don't think Germany is on a very high level in that regard.

We also ask businesses to save energy: https://www.bmwk.de/Redaktion/DE/Downloads/E/ensikumav.pdf

But unfortunately, this is not really enforceable because non-compliance is not illegal afaik.
