Cologne ran its smart-city experiments on a single shopping street. From 2012 the city utility RheinEnergie turned a four-kilometre stretch of Neusser Straße in Nippes into the 'Klimastraße', swapping streetlights for LEDs that cut lighting energy by about half and wiring flats and shops with smart meters and EV chargers. Its ParkPilot parking-guidance pilot (2020–2024) cut the time drivers spent hunting for a space by up to 45% before wrapping up — a small, real-world test bed rather than a citywide overhaul.
