Cities Save Through LED Streetlights

March 19, 2012

A number of cities across Fresno County have discovered the cost savings and efficiency of installing light emitting diode (LED) lights in the past year.

Illuminated by the movement of electrons through a semiconductor material, LED lights are known to last as long as 50,000 hours compared to 8,000 hours with compact fluorescent bulbs and up to 24,000 hours with high-pressure sodium bulbs used in most streetlights.

In Kerman, Pacific Gas & Electric Co. installed 604 new LED streetlights, saving the city about 204,200 kilowatt-hours of energy per year and cutting roughly $26,000 from its annual power bill.

The reduction in greenhouse gas emissions, meanwhile, is roughly equivalent to removing 27 vehicles from the road.  Read more about this story in the March 19 edition of The Business Journal.
