Streetlight Networks, strategic but expensive assets
Streetlight networks are strategic assets for cities. Streetlights illuminate the roads we drive on, the pedestrian paths we walk along and the public areas where we gather. It provides us with safe roads, inviting public areas and enhanced security in our homes, businesses and city centers. But the number of streetlights in a city and their wide geographic distribution make them difficult and expensive to operate: more than 40% of the city's electricity cost, manpower and service trucks for lamp replacements and other onsite operations and the resulting 218 kg of carbon dioxyde emissions per year per light point (average for a 150W SON lamp).
