LED Streetlights Save Baltimore More Than $2 Million Per Year

The largest city in Maryland is replacing 70,000 sodium vapor streetlights over the next three years with energy saving LEDs (aka light emitting diodes), reports The Baltimore Sun.
The project will help Baltimore save $1.9 million on its annual electricity bill plus $275,000 per year in maintenance costs because they don't have to be replaced as often as the old bulbs. From an environmental standpoint, the conversion will also help cut down on light pollution, reports the Sun.
So far, the first phase of the project is about 80% complete, with 8,000 new lights in place. The next phase will involve swapping out lights owned by the local utility, Baltimore Gas and Electric Co.
Despite these rather typical growing pains, however, many other Maryland municipalities and agencies are making the switch. That's because estimates from the Clinton Climate Initiative says streetlights can account for as much as 60% of a municipality's electric bill. They also last about twice as long.
That's a lot of money to be saved.
A recent analysis by the Department of Energy found that LED have the smallest environmental footprint among lighting technologies.
For that reason, they are often at the center of corporate and government energy efficiency projects, such as a major office retrofit completed in New York by Ernst & Young earlier this summer as well as a remodeling at the iconic Empire State Building.
