Turn out the lights, join Earth Hour on March 29

On March 29, you can join an estimated 21.5 million people around the world who will turn off all lights in their homes and businesses between 8 p.m. and 9 p.m. to raise global awareness of climate change.

Earth Hour is a project started in 2007 in Sydney, Australia. In that first ever event, more than 1,900 businesses and government departments, and 60,000 households, participated. As a result, demand for electricity fell 10.2 per cent. Since most of Australia’s electricity is generated by coal-fired hydro plants, the reduction in greenhouse gas emissions was the equivalent of taking 48,000 cars off the road for one hour.

World Wildlife Fund has become a major organizer of this year’s global event.
