I have Blackle and I did open a thread about it but
Seems as tho there is only a (marginal) savings if you are have a CRT. It makes no difference on a LCD display (the majority of screens now). In fact according to http://en.wikipedia.org/wiki/Liquid_crystal_display, black takes more pixels than white on an LCD screen.

As a reminder to conserve electricity, having a black screen is probably fine, but hardly a significant contribution according to what I have researched, and being the cynic I am, I am wondering if it is more of a market ploy (every one who clicks on blackle generates advertising revenue).
If you want to save power, turn off the screen saver and turn down your screen brightness instead. some other good ideas here:

Regardless of your monitor type... if you instruct your PC to put the monitor to "sleep" after some inactivity, it's power draw goes from whatever the tag on the back says (40W, or whatever) down to about a watt.
The average LCD draws about 40W, so thats 3.3 kw/hr per month and at NJ rates of 11 cents per kilowatt/hour that would be about $40 if the thing was left on 24/7 all year.
If the computer and PC are left on the same 24/7, all year, that would be about $157 a year.
Forget the environment, think with your wallet :)
