Lights on? Hit the switch. Cornell will celebrate “Earth Hour” March 24, from 8:30 to 9:30 p.m., when community members are encouraged to turn off any nonessential light in your living space or common area for 60 minutes.

“This could be Earth’s finest hour,” said Sarah Brylinsky, the university’s sustainability communications and integration manager. “Each Cornellian can easily help make a positive impact on our energy use and the university’s carbon footprint.”

Cornell can save thousands of kilowatts of electricity during Earth Hour, and the Campus Sustainability Office will be monitoring the overall power dip during the event to see how much energy was saved.

“Earth Hour is a reminder that, together, many small actions make a difference,” Brylinsky said.

Earth Hour is promoted by the World Wildlife Fund.
