Scott Alf feels the heat from light bulbs at the Osram Sylvania booth at Energy Fest Sept. 21. Alf was chaperoning a group of school students from the Ann Arbor Open School. "I'm glad to see that a lot of the presentations are at a level that the students can understand," he said. Rob Cole, I/C sales representative for the mid-central area for Sylvania, displayed energy-efficient compact fluorescent lights at this exhibit. The ninth annual Energy Fest—an information fair that showcases energy conservation and sustainability efforts—was held on the Diag and on the North Campus Portico Plaza last week. Energy Fest is sponsored by Plant Operations—Utilities & Plant Engineering and the Center for Sustainable Systems.
