Watch out North Residential Village and Upperclass Experience: The South Side just took the lead in the Campus Energy Challenge. Don’t fret, it’s not too late to reduce your energy consumption and win free T-shirts. The contest ends Nov. 15 and T-shirts will be distributed at Thwing Study Over.

To help your team win, take the stairs instead of the elevator, turn off lights, unplug chargers and other devices, turn down your thermostat, wash your clothes in cold water—anything you can do to unplug and conserve.

Learn more about how to reduce energy at Case Western Reserve University’s Big Green Event Nov. 15 at 5 p.m. in the Tinkham Veale University Center ballroom. Attend the event to find out who won the Campus Energy Challenge and learn more about sustainable initiatives around Cleveland.
