Blackle - Saving energy one search at a time

Google is unarguably number one search engine today. Millions of people uses it to find any thing and everything.
Google's home page uses black coloured font over white back ground. White colour is produced on screen when all three (fundamental) colours combines together. All three cathode ray tubes have to be active, have to be on, have to be consuming power. To produce black colour, none of the cathode ray tube is required to be active. All three CRT can be switched-off. All three CRT consumes near to zero power. Think. How much energy can be saved if only Google changes its home page to black background?
Interesting research is done by a blogger. This blogger has done some analysis and based on some realistic assumptions, he has came to a conclusion that changing Google's home page background from white to black only will save 750 Mega watts of energy per year !! (This only proves google's wide spread usage and its popularity. Hats-off to great Google.).
This black Google is now no more a dream or on-paper thing. This 'black Google' concept has came into existence. (Not by Google Inc but by some private company called Heapmedia.).

Visit to use this black Google. It is as good as Google search. Except some missing features. Like 'Cached' and 'Similar Pages' options. It does not have as many of the corresponding links that can be found on the Google homepage. It also does not have items like preferences, advanced search, language tools, images, groups, news and scholar.
Below is some of the lines pasted from wikipedia or web about blackle.
- It is is a custom version of the Google search engine. Developed by Heap Media Australia and not owned by Google Inc.
- The principle behind Blackle is based on the fact that the display of different colours consumes different amounts of energy on monitors.
- Blackle was created to remind the need to take small steps in our everyday lives to save energy
- Blackle saves energy because the screen is predominantly black which is opposite to Google.
- Messgae from Blackle team : We encourage you to set Blackle as your home page ( set ). This way every time you load your Internet browser you will save a little bit of energy. Remember every bit counts! You will also be reminded about the need to save energy each time you see the Blackle page load
- It it estimated that a black Google would save 750 Megawatt-hours a year[1]. On the Blackle homepage, the creators of Blackle provide a count of the number of watt-hours that they claim the users of Blackle have collectively saved

My this blog is kind of suggestion to Google to start same thing officially. Instead of having this energy saving Google search getting owned by another company, Google should step forward and lauch (Or acquire) black Google.

I wants to see Google like this :

At last , A search in Blackle does not necessarily return the same results as a Google search. Means Google is "Synonymous of find" while Blackle is Blackle only.
