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!

Upcoming Dates


NOTE: With the COVID-19 pandemic still limiting large groups on campus, iSEE will wait until the danger has passed before resuming Illini Lights Out activities. We can’t wait to get our students involved in saving energy and money again for the Urbana-Champaign campus!


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).
