Earth hour had some really great designs. They had the classic 60 on black paper with a cutaway of the earth in the 60. This whole event was to stop global warming by turning off your light and everything electrical in your house for 1 hour or in this case 60 minutes. As you went on websites, TV and magazines they all promoted it, especially Google with the black background on the day of.
The Aftermath
At about 9:30pm on the day of we all saw that our entire neighborhood turned off their lights and its was really amazing to see not one light on in the distance and that we were really making a difference. In the news the next day I read that overall Ontario reduced its energy consumption of 4% and they plan to do this earth hour event every year and it will upgrade to hours then 3 then 4 and so on.
