Energy Saving Search engines

Has anyone else seen/used this, or read about this?
It is a knockoff of google, and attempts to do the same thing, just with a black screen instead of a white one.
The concept behind it is that a black screen takes less energy to run off of then a white one, but according to wikipedia one critic found it actually used more power in LCD screens under 24 inches, however using your regular old style CRT monitors it did save power.
Ran into it and thought it was interesting, so I figured I would share, although I am not sure how effective it actually is in helping to reduce energy consumption, and I noticed through a quick use of it that the search engines although google-like in nature, weren't exact.

From Wikipedia,

The creators of Blackle have been criticised for lack of clarity regarding the type, size and manufacturer of monitor that the power usage claims refer to. One critic, a technology journalist who reviews computer hardware, tested 4 cathode ray tube (CRT) monitors and 23 liquid crystal display (LCD) monitors, and found that power was saved by the CRT monitors, but was less than that claimed by the blog post that inspired Blackle. The LCD monitors tested showed increased power use in the majority of cases, although most of the larger (24 inch) monitors did use less power displaying a black screen.

I think that is a bit nutty with not that much of a difference, something like encouraging people to walk more and using their car less is by far better approach.
