The facts as mentioned by bryantn3 can be found on here on Wall Street Journal based on a quick test (not a rigorous study) disputing the effectiveness of Blackle with LCD screens. The test was conducted by a consulting firm specializing in energy and environment.

“The changes were so slight as to be within the margin of error for the power meter. Tweaking brightness and contrast and settings had a bigger effect. The bulkier CRT screen did see savings with Blackle of between 5% and 20%.”

Ignore last comment. An error was made in it.
People, if you don’t know what you’re talking about, then don’t act like you do. Blackle does work because LCD screens are the same as CRT screens except that there are more pixels on the screen, and instead of a tube there is a lot of fluorescent lights, and there are seperate lights for separate colors, red, green, and blue. There is also a backing light. The backing light does use up energy, but much less than a standard bulb. What uses so much energy are the smaller bulbs, because there are so many, and there is one red, one green, and one yellow for each pixel, and only the backing bulbs are lit when it is a black picture, because to make the black, the red, green, and yellow lights are unlit. The backing bulb only makes the screen give off light rather than drawing it from things around it, and the smaller bulbs collectively use much more energy. Stop being stubborn. Don’t lie to people so that they’ll lie and everyone will believe what you say. Don’t make yourself look good. Give the real facts. Please.

Yes you can set Blackle instead of Google on the search bar just set. On bottom of firefox toolbar go to manage search engines then you can enter your own and Blackle will come up….
But I am curious about this black, white color thing…does it or does it not save energy. I’d think the folks who are encouraging Blackle use would know, but perhaps not…Also, when I set Blackle it seems to search for environmental type sites unless I click web search vs. blackle…is that a setting or other glitch…thanks, rick

You cannot place Blackle instead of Google on searchbar. Alternatively, you can place it on your bookmarks toolbar if you use Mozilla or I would recommend make it your homepage.

Blackle is just a copy of the first page of http://www.searchincolor.com, which has offered web search in color since a much longer time.
I dont know much about energy saving, but I do find green on white as the best color combination for search. That is available on searchincolor.

This is a complete joke and I can’t believe anybody is taking this seriously! If you understand how a monitor (LCD or CRT) is built, you would know that it makes absolutely no difference what color is on the screen.

Both types use a power supply which is constantly converting AC current into DC, as long as the monitor is on. If your monitor is on, it’s going to use the same amount of power.

Furthermore, LCD panels use small fluorescent tubes inside as the light source (usually two sets, two at the top and two at the bottom). They are called cold-cathode fluorescent’s or CCFL’s). They are always on and illuminate the thin space behind the LCD panel. The LCD screen itself does not generate the light, it merely filters it.

So, set your screen to whatever color you want. It doesn’t matter one bit.

No sorry that’s only with CRT’s (i think), because LCD has 4 or 5 layers and 3 of them are RED, GREEN, and BLUE, so one must think it as if it were cellophane, you put the each colour on top of each other and you would get black. It’s like when you mix paint if you mix red, green and blue you dont get white (LCD) but when you mix red green and blue lights you do get white (CRT).

White light (from the sun) is additive, using colours from the spectrum (added together) to create ‘white’. Monitors, CRTs and LCDs, use the same additive effective. When Red Green and Blue are mixed together, they create white. When RGB are at zero value, you get black pixels.
