At the April 29 Illini Lights Out event, 3,742 light bulbs were shut off, saving $542.86 in energy costs. This also prevented 4.58 metric tons of CO2 from entering the atmosphere, which is equivalent to the greenhouse gas emissions from the consumption of 515 gallons of gasoline. That's a big impact!
