More than a billion people turned their lights off on Saturday night in celebration of Earth Hour. The green blogosphere and Twitterverse was a buzz with excited greenies soaking up the darkness between 8:30 and 9:30pm as they sought to raise awareness of climate change and our need to do something about it. Just like New Years Eve, Earth Hour swept across the world as time zones ticked over to the 8:30pm mark.

Here are a few photographs from the festivities.
