Rockefeller Center Christmas tree goes LED

It looks like the Rockefeller Center Christmas tree will be a considerably smaller energy hog this holiday season than it has been in years past, as New York City Mayor Michael Bloomberg announced yesterday that the tree will be lit up with LED lights for the first time - 30,000 of 'em, to be specific. That'll apparently reduce the tree's energy consumption from 3,510 kilowatt hours per day to just 1,297 -- a savings that, as the AP points out, is roughly equivalent to the amount of electricity consumed by a typical 2,000-square-foot house in a month. While it's not clear if it'll be used for the tree or not, the owners of Rockefeller Center also took the opportunity to show off a new 365-panel solar array on the roof of one of the complex's buildings, which is apparently big enough to lay claim to the title of the largest privately owned solar roof in Manhattan.
