Raleigh, North Carolina, aims to become an "LED City" through a wide deployment over the next 18 months of lights that use light-emitting diodes (LEDs). Raleigh first installed LED lighting in one floor of its municipal building's parking garage in December 2006, and has already quantified a 40 percent energy savings and a great improvement in lighting on that floor. The project used LEDs from Cree, Inc. that were incorporated into fixtures by the Lighting Science Group Corporation (LSGC) and installed by Amtech Lighting Services. Based on the results of that project, Raleigh now plans to deploy LED lighting in its garage and parking lot lights, street lights, architectural and accent lighting, portable lighting, and pedestrian and walkway lighting. See the Cree press release and photos of the garage on the LSGC Web site.

Raleigh's "LED City" initiative may provide a preview of the world two decades from now. A new report prepared for DOE by Navigant Consulting Inc. makes projections of the price and performance of LEDs and organic LEDs (OLEDs). The most positive assumptions find that LEDs and OLEDs could save 348 million kilowatt-hours of electricity by 2027.
