The city of Seattle will help other cities move forward with environmentally friendly streetlights. Seattle was recently lauded as the leader of a national consortium of cities that want more energy-efficient streetlights, according to the Seattle Times.

In 2007, the city began replacing streetlights with more “green,” longer lasting, brighter LED streetlights.

According to the Times article, the U.S. Department of Energy chose Seattle and Seattle City Light for their work in seeking more environmentally friendly technology and carbon neutrality. The city plans to replace 40,000 streetlights in the next five years at a cost of nearly $23 million.

Seattle claims that millions of dollars will be saved on energy and maintenance.
