    Does it really consume less energy to leave the computer on the whole
    day than to repeatedly turn it off and on (maybe 3-4 times)?

    Sometimes I do overnight downloads. Any idea how costly that would
    be? The monitor shuts off after a few minutes of inactivity.

    Your computer is on a switch mode power supply (I;m assuming it isn't a
    laptop), to get that started takes fair amount of power, but once up
    consumption is basedd on consumption of your motherboard/peripherals.

    While your download is in progress it will be consuming, but when finished
    your cpu and drives can go into idle mode. Consumption at that point is

    Coming out of sleep mode is not as great a surge as a full power up, because
    your switch mode psu is already up.

    If your downloads might have periods on inactivity, then ensure you have set
    your PC to wake on lan (assuming that is your means of communication).

    Heh. I accidentally set one for just that, and it kind of scared the pants
    off of me when this idle computer suddenly sprang to life on its own. ;-)
