traffic signals use about one-tenth of the energy consumed by the traditional incandescent lights.
Knoxville is in the process of switching to more environmentally friendly traffic lights that officials say will reduce energy costs.
The new LED lights and other such projects will help create a more vibrant Knoxville, said Madeleine Weil, chair of the task force.
The city is investing $781,500 to complete the replacement project, which already has replaced 20 percent of traffic signals over the last few years. Although more expensive than incandescent bulbs, the LED signals will be more cost-efficient in the long run.
