Earth Hour

Can you stay without any electricity for 1 hour?

Earth Hour is an annual international event created by the WWF (World Wide Fund for Nature/World Wildlife Fund), held on the last Saturday of March, that asks households and businesses to turn off their non-essential lights and electrical appliances for one hour to raise awareness towards the need to take action on climate change.

It was first introduced in Sydney 2 years ago. Sydney was the only participant at that time.

This year, you are invited to do so. When? This Saturday 28 March 2009, 8:30PM local time, wherever you live on planet earth.
