Setsudener is an app that converts your twitter icon to a dimmer version only during peak electricity consumption hours, said to be between 5:00 AM – 8:00 PM. It’s a subtle reminder that there are small changes and adjustments we can make in our day-to-day lives that, collectively, can have a significant impact on electricity usage.
Setsuden (節電) in Japanese means “conserve electricity.” Therefore, setsudener can be translated as, one who conserves electricity. The app was developed by interactive director Qanta Shimizu.
(Take note that some users initially reported that their icons don’t return to normal. Per the developer, this bug has been fixed. It’s also worth noting that the app functions in Japan’s time zone.)
