Earth Hour

In case you haven't heard, tonight at 8PM the World Wildlife Foundation says we should all turn off our lights.

From the FAQ:

Does this mean I have to turn of[sic] everything in my home and use absolutely no electricity?

Not at all. The main point of this campaign is to show people and companies how easy it is to take action to avoid global warming. This does not mean you have to turn off your fridge, but we do encourage you to join us by switching off your lights and make a statement, as well as changing your habits in the long term.
