The third annual "Earth Hour" took place this year on March 29th. The first Earth Hour took place in Sydney, Australia in 2007, when 2.2 million homes and businesses turned off their lights for one hour to raise awareness of climate change and greenhouse emissions. In 2008, the numbers rose as 50 million people turned off their lights worldwide, and in 2009 hundreds of millions of people "turned out the lights" for one hour starting at 8:30 PM. One thousand cities in over eighty countries participated in the World Wildlife Fund-sponsored 2009 Earth Hour by dimming nonessential lights between 8:30 and 9:30 PM in each respective time zone.
