New Delhi: As the clock strikes 8.30 p.m. Saturday, lights across India will be switched off to mark Earth Hour, which is observed March 29 every year.
Organised by the World Wide Fund for Nature (WWF), the Earth Hour is a global environmental campaign observed March 29 from 8.30 p.m. to 9.30 p.m.
People are asked to switch off lights for an hour - as part of their commitment to the planet.
In India, various events have been planned for the day, with hotels and corporate houses pledging their support by switching off non-essential lights.
"The campaign has been very successful since it was started in 2009. From the participation of five million people in 2009, it became 10-12 million last year. Also, we saw participation from 58 cities in 2009, which grew to 150 cities in 2013," Rituparna Sengupta of WWF-India told IANS.
WWF is also organising a concert "Jam for the Hour" featuring performances by bands like Faridkot at Dilli Haat.
