A new study for Pittsburgh says that the city could save $1 million a year in energy costs and $700,000 in maintenance if they make the switch to LEDs.
The study was conducted by Pitt's Mascaro Center for Sustainable Innovation, and is titled, "Life Cycle Assessment of Streetlight Technologies." While there is still more environmental impact from the manufacture of LEDs than sodium lamps, the report says that the energy savings far outweigh the damage.
Reporter David Templeton writes, "Currently 90 percent of the nation's lighting is high-pressure sodium, including most of Pittsburgh's streetlights. Only 1 percent of the nation's streetlights are LED lighting, the study says."
