Not in use? Turn off the juice!

iSEE’s Illini Lights Out (ILO) program demonstrates the immense energy-saving impact of simply turning off the lights when you leave a classroom, lab, or study space. On a few Friday nights each month, volunteers gather to form mini lights-out brigades and tour campus buildings recording how many lights are left on (and shutting off as many as they can, of course). Volunteering takes about an hour and a half, and there are always snacks afterward! Thanks to a grant from the Student Sustainability Committee (SSC), ILO has multiple events you can take part in each semester!

About ILO

Illini Lights Out began as a one-off event organized by iSEE’s Energy Conservation and Building Standards SWATeam in Spring 2016 — at which students managed to turn out 1,500 lights in just 40 minutes — and expanded to a monthly happening during 2016-17 with the support of a grant from the Student Sustainability Committee (SSC).
