So not surprising, a white screen takes more power to display than a black screen, so when Google came up with a black version it was calculated that the energy savings could be 750 Megawatts per year if everyone switched over.
I’ll switch over….if I remember the name blackle. Kind of hard to remember though. Why can’t Google just step up to the plate and switch their main search site to black? Or maybe add black borders to begin with. That should save something, right?
