When capital cities like Paris and Berlin resolved to switch off lighting for public buildings and landmarks in July 2022 in order to save energy in the context of the Russian invasion of Ukraine, the cities created a ripple effect throughout central Europe. Images of dark iconic landmarks swept through the media and allowed politicians a momentary act of environmental demonstration. However, designers have started to question the sustainability of this ad hoc step. Seen from a broader perspective the impression arises that this alleged radical action has been part of a rather media-savvy campaign with small effect in cities at night. Further steps are necessary to reassess urban lighting that may have a major impact on energy saving and sustainability.
