Use LCD or Google’s Blackle for Saving Electricity (Energy)

Monday, July 02, 2007
In an attempt to save global energy, Google has launched Blackle some times back. The idea behind this is to save energy. The black background color of Google search is believed to save 750 mega watts annually.

Blackle powered by Google has come into being in response to a post by TreeHugger Mark Ontkush EcoIron. The post has unfolded some startling facts that an all white web page uses about 74 watts to display, while an all black page uses only 59 watts.” Please, download Roberson et al, 2002.
Google, which has a white background and gets about “200 million queries a day” could reduce global energy use by 750 Megawatt-hours a year by simply changing the color of its homepage to black.
Blackle encourages us to set the black background as the home page. This way every time you load your Internet browser, you will save a little bit of energy.

My Observation: This is a good attempt of Google towards energy saving. But this is applicable for those who are using CRT (cathode ray tube) monitors. People using LCD monitors can never use Blackle for obvious reason. Black pixels actually take more energy to display on LCD screens than white pixels do.

The global consumption of CRT monitors is declining. Despite this, CRT consumption is still high in developing countries like India, and China. The consumption of CRT monitors in China is nearly 50% and 75% in Latin America. Even the use of CRT monitor in India is very high, although many companies have started replacing CRT by LCDs.

If it’s possible for you to replace CRT monitor by LCD, you please do this not only for your personal cause but also for global cause. However, if it’s not possible for you to do this right now, at least use Blackle until you use LCD monitor.
