However, contrary to what many assume or desire, it is not run by Google themselves.
Blackle.com is registered to:
Mikiboand was registered through and runs on GoDaddy servers, on GoDaddy's network [AS26496 or via whois].
PO Box 4078
Castlecrag, New South Wales 2068
And it wraps a Google Custom Search, so Mikibo make a small percentage of the ad-money involved.
Interestingly, Mikibo is "a free service providing tools and information to help you lose weight, get fit and stay healthy". So they want to increase the amount of energy that people burn! And decrease it simultaneously! Oh the paradox!
Is there a moral to all of this? Should we blindly ignore common sense and venture outside, leaving behind Google's energy-wasting white page, into the great outdoors? Or should we all just upgrade to LCDs (ironically returning a Google Answers - since "gone black" itself - result in the #1 spot)? Although the white backlight is constantly on, the overall power usage is much lower. I'd like one (note the energy-saving nature of the black background to the pic):
