Former President Bill Clinton joined Mayor Antonio Villaraigosa in unveiling what is billed as the largest effort by a U.S. city to reduce pollution by retrofitting incandescent street lights with more efficient LEDs or light emitting diodes. Over a five-year period starting in July, Los Angeles will retrofit 140,000 of its residential street lights with LEDs, officials said during City Hall news conference. The project is expected to reduce carbon emissions by 40,500 tons and save $10 million annually.
With this city’s energy usage would fall from 197 million kilowatt-hours to 132 million kilowatt-hours over the next 10 years.
