My thinking is that if indeed laptops with b/w displays do use less electricity, it's probably intrinsic to differences in the electronics between color and b/w displays. That is, a color screen is always running in color, even if it's not _displaying_ color.
Perhaps the time difference you feel like you're noticing is a speed difference. I seem to recall having read in Mac Secrets or somesuch that you can gain a perceptible speed increase by setting your screen to b/w. Makes sense, 'cause the machine only has to process 1/3 or less of the video data. If you're just typing, you don't care about color anyway! It occurs to me to wonder if there's a difference in power consumption between active matrix and passive matrix screens.
