In the small Midwestern town of Muscatine, Iowa—known as the "The Pearl Button Capital of the World" for the millions of pearl buttons produced there in the early 1900s—a lighting retrofit project will bring a new kind of shine to the town: LED streetlights. By replacing 300 high pressure sodium cobra head streetlights with LED fixtures
the town is projected to reduce energy and maintenance costs by up to 15,000 a year.

It's easy to measure the effects of a lighting retrofit project in a city like Altoona, Pa., where 169 new LED units are expected to save $4,078 in energy costs annually. But there are also other benefits to such energy efficiency initiatives, which can be seen in the local companies that make the projects possible...

Temperatures above 100 degrees mean that staying cool and being energy efficient is important to the small town of Oro Valley, Ariz. But finding the funds to do both can be a challenge. It was this heat – and the availability of a federal grant – that Bayer Vella, the town's conservation and sustainability manager, cited as a reason the city is forging ahead with energy retrofits and solar projects.
