New York City Mayor Michael Bloomberg on Tuesday announced that Big Apple locals and tourists will enjoy the first-ever "green" Rockefeller Center Christmas tree this year.

The 84-foot tall Norway spruce will be officially lit during a ceremony on Nov. 28 with energy-efficient LEDs, or light-emitting diodes, instead of the usual incandescent bulbs.

About 30,000 multicolored LEDs in five miles of wire will cover the tree, reducing energy consumption from 3,510 kilowatt hours to 1,297 kilowatt hours per day. The savings is equivalent to what a family would use in a month in a 2,000-square-foot home.

Bloomberg together with Tishman Speyer, the owners of Rockefeller Center, also announced a new solar energy roof that will help power the Christmas tree. The solar energy roof is the largest in privately owned solar roof in Manhattan. It will reduce carbon dioxide emissions by 2,000,000 lbs. over its 30-year lifespan.

"The tree at Rockefeller Center is one of New York City's most beloved and iconic landmarks, and with the environmental steps that Tishman Speyer has implemented this year, the 500,000 New Yorkers and tourists that visit the tree each day can dream of a 'green' Christmas," said Mayor Bloomberg.

Also for the first time, the Rockefeller Center Christmas tree was cut with a handheld saw to reduce energy consumption. It will be made into lumber for homes by Habitat for Humanity after it spends 42 days on display.

The tradition of lighting a tree at the Rockefeller Center began in 1931, when workers put up a tree in what was then a muddy construction site.
