Energy efficiency and clean, renewable energy will mean a stronger economy, cleaner environment, and greater energy independence for America. Working with a wide array of state, community, industry, and university partners, the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy invests in a diverse portfolio of energy technologies.LED traffic signals provide “one of the most sustainable solutions to the energy crisis,” the report said. “Participants expect to continue using LED traffic signal modules, and perhaps other technologies as well.
In the City of Pasadena, principal engineer Jim Valentine admits that that if a municipality fails to plan properly, LED lamp replacement costs could be surprising. “At least some of the money we’re saving on energy should be set aside for new modules,” he said. Pasadena secured a state a loan of $76,024 and at the same time obtained a grant for the same amount. The funds paid for 762 green LED lamps, of which 8 to 12 were installed per intersection. “At first, a few people said that they were too bright, especially at night,” said Valentine. The complaints quickly subsided. “I don’t know if the lights got dimmer, or people just got used to them,” he says. Pasadena is saving approximately $40,000 per year in electricity costs.

LED traffic signals provide dramatic energy savings
Red LED traffic signals are far more cost-effective than signals using incandescent lamps. A red LED traffic signal costs about $75, compared to $3 for an incandescent signal. The LED signal, however, consumes approximately 88 percent less energy than a comparable incandescent signal in the same application. Over an estimated seven-year life, LED traffic signals cost 70 percent less ($290) than signals that use incandescent lamps (based on 10 cents/kWh). These economics are becoming even more attractive as LED traffic signal prices decline.
