We can have the entire house lights turned off the whole night as a regular routine but on the 29th it's with a meaning. Hehe

And I hope people from the office would at least turn off their pc's when they logout on their rest days or the lcd screen when they logout at the of the shift.
there are studies that show it has an effect on global warming - and of course.. electric bills ; )
