Time to Switch off the Lights - Earth Hour

Global warming is a pain in the *** and needs to be addressed. WWF is having an Earth Hour, at 8:30 PM on 28th March 2009, i.e Today, the date of the posting. Though it is not possible to do this globally, it's being done per country. A question that comes to my mind, with India where electricity supply is irregular, more than half of our population not having access to Electricity, will something like the Earth Hour really make a difference. I propose to shut off my car, lights, and other electronic items (No not my data center equipment) tonight at 8:30, will you .. What do you think, taking an hour off of our Electronic devices (Plugging them off), our Carbon Devices (Cars, Generators etc) will help ?
