Google has decided to have the background of all black today (instead of the usual white background) to raise awareness for a worldwide energy conservation effort called Earth Hour.

Earth Hour will be held today between 8:00pm and 9:00pm in your local time zone. I’ll be participating in the effort although I usually don’t have more than one light on at a time but maybe today my family and I will play card games by candle light (that’s an average night for me, well, except for the candle light).

I hope you all join in as well and you can go here to learn more about Earth Hour.
