Go Ann Arbor!!

A recurring theme of this blog is being green. Today's news wires are carrying a story that is very exciting!! It seems that the city of Ann Arbor, Michigan is going to replace all of its street lights with LEDs. As we've discussed previously in this blog, the LED saves a significant amount of electricity (which equals $$$$$) and lasts approximately 10 years to a 2 year life for a regular incandescent bulb.

According to the story, the city expects to recover its costs of installation through energy savings in just 2 years!! This means that the next 8 years of operation (the expected life of the LED) will be money in the taxpayers' pockets. In addition, it will reduce greenhouse gas production in an amount equivalent to taking 400 cars of the road! Where is the downside on this? Why aren't all towns and cities looking at doing this?

Thoughts anyone?
