Do the i5 machines consume significantly more power than the c2d ones?

    Probably a bit, but in the grand scheme of things (screen, hard drives and so forth) not enough to worry.
    In a laptop it would have been an issue.
    Specifically it uses about 95w.

    Actually the chips are quite sophisticated and would only use 95W when under 100% load.

    When not busy the processors actually underclock themselves and consume far less power.

    I wouldn't be surprised to find that the new i5 iMac 27" doesn't use any more power when idling or doing light tasks than the 3.06 24" did.

    Tom's Hardware has a nice article on the consumption of the Core 2 vs. Core i5/7 platforms and taking into account performance.

    You might consume more power in the short run over a Core 2 Duo but you'll get more work done per watt regardless. Your task will finish faster and using less power over all.
