9. The Rockefeller Center Christmas Tree Is the Greenest Tree Around
Setting up before the Tree Lighting Ceremony
As you can imagine, decorating the Rockefeller Center Christmas Tree is quite a costly endeavor — both financially and environmentally. That’s why incandescent bulbs were replaced with LED lights in 2007. They are now powered by solar panels, which are located on the rooftops of buildings in Rockefeller Center (see here). This upgrade ultimately helps to save 1200 kwH per day.
Mental Floss breaks that statistic down with the following comparison: “It’s estimated that a family in a 2000-square-foot home would use 1200 kwH to power their household for an entire month.”
