About Earth Hour

Earth Hour began in 2007 in Sydney, Australia. More than 2.2 million people across the world switched off their lights to show symbolic support for the planet and raise awareness of the environmental issues affecting it. 

Edmonton has participated in Earth Hour since 2007. Earth Hour gives us all a chance to reflect on our energy consumption. It is important to make energy efficiency part of your everyday lifestyle and show you care about the planet.
