Earth Hour is back on March 26 at 8:30PM. The World Wildlife Fund is asking everyone to shut off their lights for one hour to show support for energy conservation. Will you participate? And if so, what will you do for an hour without electricity? If you are stumped for ideas, the WWF Canada website has information on various activities in your neighbourhood or you can read the comment section where people are posting ideas of their own. There is also a ton of information on renewable energy and the how its usage will reduce global warming.
