New Delhi, March 10 (IANS) Actor Abhishek Bachchan has urged Indians to switch off lights for one hour on March 27 as part of WWF's Earth Hour 2010 campaign to support action on climate change. He says he will also request the film fraternity to stop shooting schedules during that period.

"People really need to be educated about about power conservation. I pledge my and my family's support to this initiative. I will, in my power, do whatever to save electricity and will request my friends in the film industry to shut down shootings in studios during the Earth Hour," Abhishek told reporters here Wednesday.

The Earth Hour, which is a concept that originated through WWF in Sydney in 2007, will be observed worldwide March 27 from 8.30 p.m. to 9.30 p.m. The actor has been appointed the Indian brand ambassador for this year's Earth Hour campaign.

Abhishek also suggested ways to save electricity on a daily basis.

"When you finish charging your phone, don't just unplug your phone, switch off the charger from the main switch as well. Switch off your TV from the main plug when it's not in use. Keep your car engine off while on a red light. These are just little ways in which we can do a lot to conserve energy," he said.

In India, 15 cities including Delhi, Mumbai and Bangalore, have pledged their support for the campaign, which led to conservation of 700 MW of electricity in Delhi last year, said Chief Minister Shiela Dikshit, who was also present at the event
