| Blackle saves energy because the screen is predominantly black. "Image displayed is primarily a function of the user's color settings and desktop graphics, as well as the color and size of open application windows; a given monitor requires more power to display a white (or light) screen than a black (or dark) screen." Roberson et al, 2002 In January 2007 a blog post titled Black Google Would Save 750 Megawatt-hours a Year proposed the theory that a black version of the Google search engine would save a fair bit of energy due to the popularity of the search engine. Since then there has been skepticism about the significance of the energy savings that can be achieved and the cost in terms of readability of black web pages. We believe that there is value in the concept because even if the energy savings are small, they all add up. Secondly we feel that seeing Blackle every time we load our web browser reminds us that we need to keep taking small steps to save energy. How can you help? We encourage you to set Blackle as your home page. 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. Help us spread the word about Blackle by telling your friends and family to set it as their home page. If you have a blog then give us a mention. Or put the following text in your email signature: "Blackle.com - Saving energy one search at a time". There are a lot of great web sites about saving energy and being more environmentally friendly. They are full of great tips covering the little things that we can all do to make a difference today.

| Maybe we should think about making an energy saving forum skin once we upgrade our Zetaboard forums (whenever that is)? :huh: |

| Surely that energy usage statistic only applies to CRT monitors, LCDs use the same amount no matter what colour it's displaying. |

| Now take into account that about 25 percent of the monitors in the world are CRTs, and at 10 cents a kilowatt-hour, that's $75,000, a goodly amount of energy and dollars for changing a few color codes. |

| The only major issue I have with my LCD is that the brightness can change based on viewing angle. So if I lean back it gets darker. Aside from that it's great. |

With my CRT however after 3 years the image flickers or just shrinks down to a single line every so often and it won't come back unless you turn it off for 10 minutes. I find this to be a major disadvantage to CRT monitors. |
