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 pioneered by WWF Australia and the Sydney Morning Herald in 2007,[1] and achieved worldwide participation in 2008.

Earth Hour will next take place on Saturday, March 28 2009 at 8:30 pm, local time.

Earth Hour isn't just to do with reducing the consumption of electricity for just one hour.It's about letting governments know it's time to take care of our Planet Earth. Earth Hour gives you a chance to have your say, by turning off your lights you are voting to save Earth or if you don't you support Global Warming.

2009 Earth Hour is hoping to get 1 billion votes, which will be presented to world leaders at the Global Climate Change Conference in Copenhagen 2009.

This meeting will determine official government policies to take action against global warming, which will replace the Kyoto Protocol.

It started here in Sydney 2 years ago in 2007 and now look at what has happened, a lot of people around the planet are talking about it and joining in to let Governments know it's time to save Earth. Earth hour was last night for me here in Sydney and I looked out my window and noticed a lot of people turned there nights off including me.
