Energy-saving app turns off PC monitor when users walk away

GreenCam is a PC app that automatically turns off the user's monitor when he or she walks away from the computer.

It’s become increasingly clear that new technology can help eco-minded consumers save energy, but few examples achieve that goal as effortlessly as GreenCam. The brainchild of Brazilian Ecobenefícios, GreenCam is a PC app that automatically turns off the user’s monitor when he or she walks away from the computer. Now available as a free download from the Ecobenefícios site, GreenCam turns the user’s webcam into a motion sensor. Every time the user moves away from the front of the machine, GreenCam detects this, and turns off the screen to save energy. The video below explains the premise in more detail: Whether it’s home energy metering or reducing auto emissions, there’s no end in sight to the many ways apps can help minimize users’ carbon footprint.
