Tio the Energy-Conscious Lightswitch
Even in your child’s most mundane moments, like turning on the play room light, make sure they’re aware of their energy use. Designer Tim Holley designed the clever and cute Tio ghost as a way to inform kids, in a fun way, of how much electricity they use. The Tio shines green when he is happy (when lights have only been on for an hour or less), and slowly turns to yellow when he’s "medium," and red when he’s angry (when the lights have been on for over eight hours). It’s a fun take on a serious subject, but probably incredibly effective at bringing energy conservation "to light" for the younger generation.
