    it depends on how much your electricity costs you, and how heavy you use it.....

    No idea, but its different for every iMac and how you use it.
    No one can answer that precisely unless you state, which iMac with what specs from what year, what you will be doing with it (under full load any computer will use a lot more electricity than when running 99% idle), and for how long it will be running every day.

    Well to give you an idea on the power savings i'm experiencing with my 2011 imac i was using a dell xps 400 with 19" lcd as my main pc before purchasing the imac. My old machine was using 250w while the monitor was off when idling (sleep) and about 300w-325w when running normally. My imac uses about 1-2w when in sleep mode and upto 125w when running. So thats quite a difference. I also notice my laser printer uses less electricity now as my machine doesn't wake it up on its own at random times. When my laser printer is woken up it uses nearly 1000w of electricity for about a minute at a time. My old machine used to wake it up every 30-45 for no apparent reason. So all in all i'm saving a lot of money by switching over to the imac.

    Wow, so does the iMac use a lot less energy than Window computers? Or just certain Windows computers?

    In general it uses less than windows machines. Check apple.com they have quite alot of information on how they are the only pc company with the epeat gold certification.

    It doesn't have anything to do with "Windows" or "OSX", it has to do with hardware. The operating system isn't the determining factor here.

    Are they rationing electricty where you live or are you planning on running multiple iMacs?

    No, I'm just wondering how much money would be spent if I didn't sleep the iMac before sleeping everynight.

    ----------

    Is there a list of computer companies by their energy efficiency?

    It's going to differ for every computer based on hardware. The company isn't really significant because every computer company carries a wide line of computer types. A Mac Pro is going to use significantly more energy than a Mini, a fully-spec'd Dell is going to use more than a nettop, etc.

    How could I find out how much electricity an HP Touchsmart all-in-one might use?

    We've got two iMacs and three Mac minis in the house. We did notice a decrease in the electric bill when we replaced (Dell) PCs with the Macs. All of the Macs except the mini server are configured to sleep when not in use. This is where the major power savings comes from. The server runs 24/7, of course, but consumes roughly 1/4 the power of the Dell computer it replaced.

    These days the displays are the major power consumer. The 21.5" iMac is much more power efficient than the 27". Modern, large flat screen TVs consume as much power as the vacuum tube color TV sets of the 1950's and 1960's. So always sleep or turn off displays when not using them.

    It doesn't work that way.

    Each component has different energy use, and all companies, without exception, are building computers from the same list of hardware. Apple doesn't make anything that's inside its computers, any more than Dell or Toshiba does. Intel and ATI and Crucial and a hundred other companies make the stuff, Apple and Dell (etc.) make the pretty boxes.

    Generally speaking, the newer gear is more efficient, and the more expensive gear is more efficient - versus performance. And of course, weaker gear is mostly lower draw.

    So people often erroneously associate Apple with power efficiency because they're using mostly medium-high end components and weak GPUs (GPUs being one of the biggest power hogs in the machine).

    It's cut about $10 a month from the electric bill when we went from three Dell desktops (which were admittedly power hogs) to the 2 iMacs and 3 minis.
