Seattle is one of several U.S. cities planning to use federal stimulus funds to retrofit streetlights with energy- and cost-efficient LEDs. Seattle will use its funds from the Energy Efficiency and Conservation Block Grant (EECBG) program to replace all 40,000 residential streetlights with light-emitting diode (LED) technology. The conversion is expected to take four to six years.
Other cities and small towns are launching similar plans. Arlington Heights, Illinois will spend part of its federal stimulus money to retrofit decorative lighting in downtown Arlington Heights with LEDs, a move expected to slash the city's annual electricity bill by $6,100--more than half the annual amount from previous years. Meanwhile, the Boise, Idaho city council has recommended that Boise use stimulus money to retrofit five city parks and convert about 725 historic, 150-watt high-pressure sodium streetlights to LED technology, which--like Arlington Heights--will result in an estimated 50 to 60 percent savings in electricity costs.
