Grand Central Terminal – New York City, originally uploaded by Chalky Lives

Illustrating just how easy it is for organizations to save both money and reduce carbon footprint, MetroNorth switched a majority of their lamps to CFL’s:

In time for Earth Day, MTA Metro-North Railroad has completed the conversion from bare, incandescent light bulbs to environmentally sustainable compact fluorescent light bulbs.
With more than 1,700 CFLs installed throughout the public areas of the terminal, the railroad expects to save more than $100,000 a year on utility bills and more than 100,000 kilowatt hours in electricity. And because these bulbs last up to 10 times longer than incandescent bulbs, the railroad will save thousands of dollars on replacement costs.
Because of the need to maintain the aesthetic standards of the landmarked terminal, the switch to CFLs in public areas of the terminal was not possible until the introduction of bulbs that closely mimicked the shape of incandescent bulbs.

So not only are the bridges of New York becoming more energy efficient but also major historical buildings as well. Golf clap.
