Traffic light stickers may save lab energy safely

Safe to shut down?

Green means Go ahead and turn it off after use. Yellow means Ask someone. Red means Don’t ever turn it off. Simple messages can save labs energy and prevent accidental damage to long-running experiments. Credit: Meggie Patton/Brown University

Labs exist for experimentation, but in a few labs of the Division of Biology and Medicine, the subjects are not only cells and tissues, but also the researchers themselves. A Brown is Green initiative is piloting a way for people to save energy in the lab without worrying that they’ll compromise their work.
