Earlier this week, wiremen unscrewed the last remaining incandescent bulbs in iconic Grand Central and replaced them with compact flourescent bulbs.
The effort started in the mid-1980s, when tube-shaped flourescents were installed on the train platforms. As technology and aesthetics improved so that flourescents emitted light indistinguishable from incandescent bulbs and could be dimmed, the flourescent bulbs were added throughout the station. Now, the entire station is lit by a green lighting system, saving the city a significant amount of energy and money.
Replacing the roughly 4,000 bulbs that light the public areas of the terminal 24 hours a day will save an estimated $200,000 a year. That doesn't even include the lights on the platforms, train yards of office space.
