In 2007, Mark Ontkush, the brain behind ecoIron, wrote an interesting post suggesting that Google could save tens of thousands a year, along with hundreds of Megawatt-hours a year, if they changed their background color from white to black.

The theory, which has been hotly debated, is based on the fact that different colors consume different amounts of energy on computer monitors. However, this is only really true for CRTs, which run much hotter when a white screen is loaded, vis-à-vis a black screen. LCDs, not so much.
