Eugene I think it makes sense that there are no tangible energy savings on LCDs. LCDs work by filtering out polarized backlight. So I would expect black pixels to consume roughly the same amount of energy as white pixels. I think it makes far more sense to sleep or turn off computers to save energy. Also, those 1700 lumens GE light bulbs consume 26W of power compared to a comparable 100W incandescent light bulb. andrewb Things like blackle just prove that PT Barnum was right. < Eric's Blog Home |
