Earth Hour began in Sydney, Australia in 2007 and in the space of three years has become a global sustainability movement. More than 50 million people across 35 countries participate as homes, skyscrapers, office blocks and landmarks turn off their lights. It's not a case of turning off the lights for 1 hour each year making a huge change but rather a reminder to take responsibility, to get involved and lead the way towards a sustainable future.

In British Columbia the electricity load dropped by 1.04 per cent during the hour. From 8:30 to 9:30 p.m. British Columbians saved 64.6 megawatt hours of electricity – the equivalent of turning off about 1.4 million lights. If the province implemented the same conservation measures for one hour every evening, the combined savings would be enough to power close to 2,200 homes for an entire year.

Boston.com has a number of great photographs from around the world, taken prior and during Earth Hour. You can see them here
