Our stars are living the green life! Check out the video below and hear from Kari Wuhrer from Syfy’s Sharknado 2, Martin Passocre and Stephanie Szostak from USA’s Discretion, Julie Benz and Grant Bowler from Syfy’s Defiance, David Walton from NBC’s About a Boy, Tim Love from CNBC’s Restaurant Kickstart and the cast of NBC’s The Night Shift. They’re sharing how they go green, year round—and, in keeping with this year’s “Lights Off. Screens On.” theme—what they do when the lights are off.

And don’t forget to pledge how many lights you’ll turn off for Earth Week and enter to win an energy efficient, smart TV!
