It's coming on the 29th of this month; it's called "Earth Hour". Kind of an interesting idea although not original or unique. We need to be reminded to take some time and put thought into how much energy we waste on an hourly basis, ie. walk when we can, reuse, recycle, turn off unnecessary lights, remind the kids to take a picture of the open fridge as they complain that there's nothing to eat, (remind them of the "garbage dump" kids in the 3rd world.)
