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 lights-out brigades that fan out across campus to record how many lights are left on and shut off as many as they can!

Launched in Spring 2016 as a one-off event, the program expanded during the 2016-17 academic year with the support of a grant from the Student Sustainability Committee (SSC). It now includes multiple events you can take part in each semester. Volunteering takes about an hour and a half, and snacks are provided afterward courtesy of SSC! Join us to help save energy, cut utility costs, and avert emissions!
