At last Friday's Illini Lights Out event, 4,204 light bulbs were shut off that otherwise would have been left on all weekend, saving $639.62 in energy costs. This also prevented 5.14 metric tons of CO2 equivalent from entering the atmosphere, which is equivalent to the greenhouse gas emissions from the average car driving 12,757 miles. That's a huge impact!

Friday was the semester's last Illini Lights Out event, but there will be five more events in the spring. Stay up to date with the dates of these events and other sustainability-related events and news by signing up for the Institute of Sustainability, Energy, and Environment (iSEE) newsletter here.

Illini Lights Out addresses objectives 2.2 and 2.2.2 of the iCAP, or Illinois Climate Action Plan, to increase energy efficiency and reduce building-level energy. Find out about other iCAP objectives here and read the entire iCAP here.
