Black is not the new green, according to Google. Blackle is a website that uses a custom search engine provided by Google and displays all their results with a black background. This would have been a great idea except for the fact that users are moving towards flat screen technology in greater numbers. Displaying a black page on a flat screen actually uses slightly MORE power. If you have a big, old, power sucking monitor, and you want to reduce your plastic consumption by not upgrading, you could consider using sites like Blackle.com to reduce your power consumption slightly. Powering down completely when you are not using your computer will save more electricity. When the time comes to buy another computer monitor, look for EnergyStar 4.0 compliant units.
