On March 29, 2008 people and cities around the world will be switching off their lights for one hour to reduce energy consumption and draw attention to climate change.
Last year 2.2 million people and 2100 businesses in Sydney Australia turned off their lights for the first Earth Hour. This massive collective effort reduced Sydney’s energy consumption by 10.2% for one hour, which is the equivalent effect of taking 48,000 cars off the road for a year (wow, just think of the difference people could make if we switched off lights more than one hour one day –and switched off our cars as well!). The action drew attention from the world. This year, millions of people in some of the world’s major capital cities, including Copenhagen, Toronto, Vancouver, Chicago, Melbourne, Brisbane and Tel Aviv, will unite and switch off for Earth Hour, 8pm March 29.
If everyone switches off at 8pm, viewed from space, spots of light will be going dark in a wave moving across the globe as the Earth turns. It would be great if all the lights in Vanouver were turned off, and we could actually see the stars!
