In about half an hour we'll be participating in our second annual Earth Hour, which involves shutting off the lights (and the computers, and unplugging electronic devices) at 8:30 PM, regardless of time zone, for one hour. It is part of a global warming/climate change awareness campaign by WWF.
People argue that shutting down for one hour doesn't make much of a difference, but its goal is to raise awareness (rather than suddenly save a bunch of energy, which it also accomplishes.) Video footage from last year left me breathless and teary-eyed, especially seeing the whole-hearted participation of cities across the world. There are already some great photos up on the web page, and I'm sure folks will be putting plenty of videos on youtube as 8:30 PM marches across the world. Here is a video about the event, including lots of footage from last year. Australia, where the event began, has really proven to be a leader in this.
Now I just wish I had some like-minded neighbors with whom to share some wine and candlelight!
