The Brooklyn Bridge in New York will turn 125 years old next year and it’s time for a modern makeover. Within the year, the landmark bridge and many of the city’s other bridges will “go green.”

The famous necklace lights on the bridge will be switched from 100-watt mercury vapor lamps to 24-watt bulbs. The new light-emitting diodes (LEDs) will not make the 160 lights on the bridge appear any dimmer, according to New York Mayor Michael Bloomberg.

Other eco-friendly changes that will be taking place in the city including replacing 25,000 street lights, testing three hybrid garbage trucks, and phasing in hybrid police cars and fire engines.

This holiday season, the Rockefeller Center Christmas Tree is also using energy-saving lights. Plus, solar panels on top of 45 Rockefeller Plaza are helping power the tree.

The mayor’s goal is for the city to reduce its greenhouse gases by 30% by 2030. Over the next several years, many progams will go into place to improve the light and operations of municipal offices, the fire and police department and schools throughout New York.
