Sweden's Largest Energy Saving Experiment for E.ON has won several awards including Gold in One Show and London International Awards as well as a Grand Prix in Eurobest 2013. 10 000 people participated in the experiment and cut up to 15% of their home electricity consumption.

Now it's time for the next step. E.ON is giving away 120 000 electricity meters that show how much electricity you're using through an app. Customers can choose different types of electricity visualizations: 

Cute little Bongo works like a tamagotchi and becomes sad when you use to much electricity. Swedish legendary fashion designer Gunilla Pontén is the drummer who's drum-kit grows if you're saving electricity.And Swedish comedian Kristoffer Appelquist is your coach who becomes very angry if you're not doing well.
