REMAKING CITIES INSTITUTE
The City of Pittsburgh intends to replace its entire inventory of 40,000 street lights with light-emitting diode (LED) fixtures over the next five to ten years. When fully implemented the project is expected to save annually an estimated $1.7 million (70% savings) in energy and maintenance costs. In addition the conversion will reduce carbon dioxide emissions by almost 7 million metric tons annually.
