At Friday's Illini Lights Out event, 4,145 light bulbs were shut off that otherwise would have been left on all weekend, saving $631 in energy costs. This also prevented 5.07 metric tons of CO2 equivalent from entering the atmosphere, which is equivalent to the greenhouse gas emissions from the consumption of 570 gallons of gasoline. That's a huge impact!

Friday's event was the last Illini Lights Out event of the semester. Stay up to date with other sustainability-related events and news by signing up for the Institute for Sustainability, Energy, and Environment (iSEE) newsletter here! You can also find iSEE on Instagram, Facebook, and Twitter.
