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

Can't seem to find this info anywhere.

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.

Someone posted the following link regarding CPU power consumption in another post:
i7 & i5 Power Consumption

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.
