A new University of Pittsburgh
study recommends Pittsburgh should replace its 40,000 streetlights with LED lighting, reports the Pittsburgh Post-Gazette
The study, by Pitt's Mascaro Center for Sustainable Innovation, says Pittsburgh--which spends $4.2 million annually on electricity and streetlight maintenance--could save $1 million each year in energy costs and $700,000 in maintenance costs with LED (light-emitting-diode) lighting.
The 131 million streetlights in the United States produce 128 million metric tons of carbon dioxide pollution. With LED lighting, Pittsburgh would reduce CO2 emissions by 6,818 metric tons per year, the study says.
"The University of Pittsburgh looked at what is the best product from cradle to grave approach on the environmental impact, and one of the first studies done on urban lighting," city Councilman Bill Peduto said. "The report clearly demonstrates with all the technology out there that LED has the best impact from an environmental point of view."
Last February, City Council formed six subcommittees to lead a Pittsburgh Streetlight Conversion Task Force in evaluating streetlight replacement citywide. Councilman Peduto and Lindsay Baxter, sustainability coordinator in Mayor Luke Ravenstahl's office, say the task force studies will serve as a standard tool for municipalities worldwide to evaluate streetlight technologies.
With completion of the Pitt study, Baxter says she and the mayor's office now are leaning toward LED lighting. But a final decision will await completion of all the task-force studies.
The hope is to seek bids in June and begin streetlight construction in late summer. The project will progress in phases to allow the technology to mature and costs to decline.
