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.
An Energy Efficiency and Conservation Block Grant paid for 143 of the lights through the American Recovery and Reinvestment Act of 2009 and a program administered through the U.S. Department of Energy and the California Energy Commission.
The federal ARRA stimulus also saw to the installation of 158 LED streetlights in Parlier, saving the city about 86,268 kilowatt-hours of energy per year and reducing its annual power bill by roughly $10,350.
Kingsburg got 226 new LED streetlights toward its goal of replacing 364 of the 436 city-owned streetlights. When complete, the city will save about 68,000 kilowatt-hours and roughly $8,400 in energy costs.
The City of Sanger also completed work on replacing 475 streetlights with LEDs with the federal stimulus grant and an interest-free loan from PG&E.
Chowchilla installed 159 LED streetlights, saving about 108,258 kilowatt-hours a year and $8,171 to its annual energy bill.
The City of Fowler had 51 new LED streetlights put in, saving 31,192 kilowatt-hours a year and shaving off roughly $3,791 from its energy bill.
In Selma, 200 new LED streetlights were intalled, cutting out about 95,300 kilowatt-hours a year and saving an estimated $11,584 in annual energy costs.
In all, about 20 cities throughout the San Joaquin Valley committed to using the Energy Efficiency and Conservation Block Grants to retrofit its streetlights with LEDs.
Madera County is saving about $535,000 kilowatt-hours a year and $64,000 on its annual energy bill through recent energy efficiency retrofits that included new LED bulbs and smaller T8 flourescent bulbs.
