We haven’t been giving Ann Arbor, Michigan [2] enough attention and the city deserves it! Last year Ann Arbor joined forces with LED manufacturer Cree, Inc [3], on an ever-expanding citywide LED initiative to save energy and reduce greenhouse gas emissions. With a recent retrofit contract signed with Lumecon [4], Ann Arbor is on its way to being the first U.S. city to light up its downtown with 100% LED technology!

The city strung its holiday cheer with about 114,000 LED lights and plans to convert all of its downtown public lighting starting with more than 1,000 LED streetlights. The effort is aligned with other North American cities like Raleigh, N.C., and Toronto, which have both started similar energy-saving efforts.

When Ann Arbor reaches its ambitious goal, city officials expect to see energy use for public lighting cut in half and a reduction of 2,425 tons CO2 annually. The city also expects a short payback of 3.8 years on its investment, which was funded in part with a $630,000 grant from the Ann Arbor Downtown Development Authority [5].

A pilot program on one city block with 25 LED lights [6] helped bring the LED idea from theory to application with three years of research on how the technology saves the city about 50% on energy and maintenance costs. Based on their research, Ann Arbor city officials project an annual savings of over $100,000 on just the first 1,000 retrofits alone. The city plans to complete the conversion to LED over the next two years.
