Green isn't just the color of Christmas trees.
Being green is also how actress Brenda Song and her family celebrate the holidays.
"Something that my dad does every Christmas, which I love, is all of our Christmas lights are solar powered," Song told us at the OP Winter Wonderland party in Hollywood. "During the day they soak up all the sun and at night they roll over to the solar power, which is really cool."
"Every year, my dad and I—I'm 23 years old—and we still get in the car and drive around and look at Christmas lights," she laughed. "In our same neighborhood."
