Turn out your lights tonight!

In 11 hours people around the world will turn out their lights and any other electronic devices between 8 and 9 p.m. local time in an effort to make a statement about global climate change. The movement, called Earth Hour, started in Sydney last year as a way to inspire people to take action on climate change. 2.2 million people in Sydney turned out their lights for one hour last year making a 10.2% reduction in energy usage—the equivilent of taking 48,616 cars off the road for a year. Now that the movement has gone worldwide, let's see what a difference we can make this year.

Information and marketing about Earth Hour has been popping up all over the place this year between Facebook and Hollywood stars jumping on board. Even Google's homepage is black today in support of Earth Hour, so turn out your lights tonight at 8pm!
