The big tree at Rockefeller Center in New York is getting a facelift this year with energy efficient LED lighting.

Tishman Speyer, the company that manages the landmark group of buildings, also installed 70 kilowatts of solar panels on the roof of 45 Rockefeller Plaza, which it said would generate more electricity in its first year than the tree lights will consume over the 42 days they will be illuminated.

"We have here the largest private solar roof in Manhattan, which will help conserve energy, eliminate carbon dioxide, and power the 30,000 LED lights on our iconic Christmas tree," said Jerry Speyer, chairman and CEO of Tishman Speyer.
