what are you doing march 29?

How about turning off the lights for an hour?

It began in Sydney with the question, "How can we inspire people to take action on climate change?"

On 31 March 2007, 2.2 million people and 2100 Sydney businesses turned off their lights for one hour - Earth Hour. This massive collective effort reduced Sydney's energy consumption by 10.2% for one hour, which is the equivalent of taking 48,000 cars off the road for one hour.

With icons like the Harbour Bridge and Opera House turning their lights off, the world took notice. Inspired by the collective effort of millions of Sydneysiders, at 8pm on March 29, 2008 millions of people in some of the world’s major cities will unite and switch off for Earth Hour.
