The brief
For Wipro EcoEnergy’s Earth Hour 2015, we turned a simple employee challenge into something everyone could see building in real time.
Wipro would switch off non-essential electricity across its locations worldwide for Earth Hour, 8:30 to 9:30pm on Saturday, 28 March 2015. The question was how to make employees part of it, rather than an audience to it.
The idea: every employee action would add to a shared, visible outcome.

A live challenge
In the week leading up to Earth Hour, employees took the challenge every day: a question on energy and sustainability, with yesterday’s answer revealed the next morning.
Every correct answer added one minute to the time Wipro’s lights would stay off. Instead of individual scores, those contributions appeared as a growing cloud of +1s flowing into a collective counter, so everyone could watch the total rise as colleagues across Wipro took part.

Real-world impact
The counter wasn’t just a visualisation. It set how long Wipro’s offices would observe the shutdown beyond the hour itself.
Correct answers added 1,858 minutes of darkness across Wipro’s locations.
Offices in India and in Shanghai, Johannesburg, Reading, Mississauga, Chicago and Edmonton took part.


From the CEO's desk
The results went to the top. Wipro’s CEO featured the challenge in his “Let’s Talk” column, “When the lights go out: towards a brighter future”, describing how employees extended the shutdown:
“In addition to this hour, we decided to add a minute every time someone correctly answered a question about Energy Saving and the Environment on an online portal.”
The official thank-you mailer that followed was titled “The Earth Hour Challenge, and how Wipro successfully stood up to it!”


The idea
The most interesting part of the project wasn’t the quiz. It was making collective participation visible.
Instead of telling employees their actions mattered, the platform showed them exactly how those actions accumulated into something much larger, and then turned that total into real minutes of lights off.
