We created stickers that perfectly fit the light switches of every home. We distributed the stickers to the elementary school children through a public organisation.We have also sent the stickers to families who have expressed their interest in saving electricity.

As a result, Osaka was able to cut power consumption by 8.4% from the previous year.
