The National Zoo is touting the use of environmentally-friendly LED lights in its holiday displays. “Zoolights,” which runs through Dec. 30, has “larger-than-life displays” of many of the Zoo’s popular critters.

And (wee!) sponsor Pepco “will educate visitors about simple practices they can adopt in their households to save energy.”

Have you used these LED lights on your home or Christmas tree? How do they look?

National Geographic says that if everyone replaced their conventional holiday light strings with LEDs, at least two billion kilowatt-hours of electricity could be saved in a month – enough to power 200,000 homes for a year.
