Looking for a fun way to teach your kids about the merits of conserving electricity? Check out the cute Power Hog, a pint-size power monitor that introduces kids to energy efficiency by piggybacking upon the familiar format of the piggy bank. Simply plug the hog’s tail into an outlet and feed it a coin to meter out 30 minutes of energy for TV, video games, or other activities. A novel way to associate energy conservation with savings, the Power Hog is just one of fifty great finalists in this year’s Greener Gadgets Design Competition.

The Power Hog is an ingenious gadget that teaches kids about the cost of electricity while helping parents meter out time spent watching TV. Once a coin has been inserted, the Power Hog lights up and appliances plugged into its snout power up. The hog’s casing will be composed of an upcycled resin made from recycled PET bottles, and it will ship with eco-friendly packaging.
