Economics Minister Robert Habeck calls for energy saving: “80 million for energy change” is the name of the campaign. And that means all of us. As if turning out old lightbulbs and shutting down computers could do anywhere near as much as the right laws. To the speed limit, for example.

Especially in connoisseur circles, it is still considered good manners to smile smugly when someone calls for saving energy. Water reducing shower heads. Lights off when no one is in the room. Down with the room temperature. Lid on the saucepan. Or even speed limit. This is too piefig for many. “I need my bubble bath three times a week,” said an acquaintance the other day, as if about his heart pills.
