Would love to know what his KWH consumption is per month. His electricity bill is 1/2 mine. Is electricity generally cheap in North America?

I can tell you that in Europe, €0.20-0.25/kWh (about US$ 0.30-0.37, ZAR 2.20-2.80) is typical for residential customers.

Ok, that is fairly expensive. I pay 0.74 ZAR (~0.097 USD) per KWH.

Although, a recent proposal of a 135% increase over the next three years is under discussion.

I pay $0.085 per Kw/H. That's lower than most of the US though. I can power my 1400 sqft house with a macbook pro running 24x6 for about $90/month.

You live in a wonderful country!

Where is the wasted energy lost to? If it is lost to heat and you have electric heating in your house, would that lead to a correspondingly lowered heating bill?

On the other hand, if you are running air conditioning, you'll have to pay once to generate the heat (the computer), and pay again to extract the heat from the house (air conditioning).

I'm not sure, but NPower in the UK appears to be 8 pence (about 12 cents). That does seem low!

My figures include taxes and average amortization of any fixed costs. That said, UK energy prices do seem to be lower than in central Europe; I'm not sure why.

Side benefit of low power: low noise. That's actually the first thing I check when buying a new computer. How silent is it?

The Mac Mini is almost completely silent unless the CPU is being maxed for long enough (a few minutes), causing the fan to kick in.

It is not unreasonable to expect CPU be maxed out while computer is switched on. If you don't use it why do you keep it on anyway?

It was a big disappointment for me to find out that my new Unibody MacBook Pro whines like a rack server even with a slight load of way below 100% on one core. Meanwhile my old MBP was barely noticeable with 100% on one core until the fans got a bit worn out.

auto sleep your computer after x minutes of idle. done.

There are many things beside auto-sleep that can save you power, in fact an LCD monitor consumes as much power as an idling Mac Mini (roughly 20W each). Simply setting your monitor to auto-off when not in use can save you vast amounts of energy, your typical LCD monitor consumes no energy while turned off by the computer. A CRT (for those who still use them) save phenominally when turned off, dropping from ~70W-80W d…

So I'm still not sold on Mac Mini's as environmentally friendly desktops, as there are better solutions out there, namely my old laptop still beats the Mini in efficiency terms.

That and the lack of built-in UPS is why I never found Mac Mini a reasonable buy.

Oh come on...

Computers get more efficient all the time. My last power hungry desktop was replaced with a mobile ultra low voltage CPU notebook. Guess it paid for itself, too. But it wasn't from Apple, so I didn't make a fuss about it.

You know what, since you are so good at maths, I could sell you my old car for 10000 bucks. That way you would save 20000 bucks because you would not have to buy a more expensive car instead.

No it isn't. I tried to use my PowerPC Mini as a homeserver, but my gf complained about the constant noise, so I had to switch it off. The fan is spinning continuously.

That is the max. it actually slurps about 35W under load edit: and then you need a display of some kind ;)

Your energy-star rated 20"+ screen (with an LCD backlight) typically consumes 20W when on and 0W when powered off by the computer. So I believe the Mini would consume, on average under use, about 55W, which is a rather commendable figure for an official desktop and not a nettop. Adding peripherals will obviously effect this, a portable hard drive can pull up to 18W (maxing out the USB power supply). I'd definitely sa…

I was wondering if the Mini 1TB with OS X Server is as usable and accessible to a new user as any standard OS X

Yes, but:

- Mini has 2.5" drives, so 1TB is not possible yet - Why would you use OS X Server? There's nothing in it that you need
