Seriously though, for all google does regarding efficiency and being generally environmentally aware, they'd be doing that ethos a favour by taking the page down and saving man hours and processing time from it being a pointless distraction from anything constructive.
I doubt goog still concern about eco green, those instant search surely burn lots of cpu processing at their backend.
But one page serp surely green enough. ;)
