call-me-kenneth writes "Business Week covers the soaring demand for power and cooling capacity in data centers. Electricity consumption for US data centers more than doubled between 2000 and 2006. Among the other stats: for every dollar spent on computing equipment in data centers, an additional half dollar is spent each year to power and cool them; and half the electricity used goes for cooling. Iceland, with its cool climate and abundant cheap power, is courting big users like Google and Microsoft as a future data center location. (Can't help thinking they're gonna need a bigger cable first, though.)"

Five considerations:
1) they like to go whaling; not necessarily a friendly thing in by some opinions
2) latency; not as a bad as a sat, but not as good as Chicago for US; geo centric for North America and EU
3) earthquakes and unsettled geography
4) too many thermal pools to screw off in

If that's Homer as in Homer Simpson, the server name would be margedottir. In Iceland, the daughters are named after their mothers.
Iceland is probably cool enough that a well designed data center could forgo air-conditioning, unlike the eastern Oregon or eastern Washington sites popular for data centers.

No, they aren't, at least not as a general rule. The general rule is that all children are "named" after their father (and I'm putting that in quotes since it's not really a name as much as a *description* of who you are); it's possible to use the mother's name instead of the father's, too, but it's neither restricted to nor standard for either sex.
(Also, to pick some nits, you've misspelt "dóttir" (and don't tell me about English dropping accents - it's a different letter, not an accent), and the father's/mother's name is put into the genitive case. For example, the son/daughter of Anna could be Önnudóttir, not Annadóttir or Annadottir - that is, assuming their patronymic name wouldn't be, well, patronymic (deriving from their father's name), of course.)
Hope that clears it up! :)

Make use of the waste heat (Score:5, Insightful)
Alaska is actually a good place to implement such a solution. There is a huge amount of sunlight in the summer which, assuming you can avoid frosts, can grow amazing produce. All you need are greenhouses and a heat source. In the winter, when sunlight is no longer plentiful and farming shuts down, the heat can be pumped into local housing. Such a solution would also provide local produce in Alaska - produce that is fresh and doesn't require expensive shipping. One last point about Alaska, it's very central. It might not appear to be when looking at a map, but if you look at a globe you will see that it sits nicely between Asia and North America. I don't know where the current internet pipes are located but if they pass close to Alaska then this idea would be worth some consideration.

As for Alaska, it has some advantages, but if the energy problem is as bad as TFer_Atvar says, that would be hugely prohibitive. Iceland not only has a cold climate, but has abundant geothermal energy. Unfortunately, it seems a lit

Cold climates have several real challenges for data centers. From an HVAC standpoint, there are two general ways to cool a data center in a cold climate-- outside air only and air/water cooling. Air/water systems have drycoolers with glycol kept around 30-40F, and circulate the cold water throughout the building to fan coil units. Minimal outside air is brought in for "fresh air," and must be humidified which generally requires a lot of energy.
The air-only systems bring in 100% outside air, but must first temper (heat-- to avoid condensation) it and increase the humidity to control static inside the space. Very little pump energy, but the humidification and pre-heat are expensive.
While it seems trivial to filter out dust, the better air filtration systems increase the pressure drop of the air handling unit, and force you to use a bigger fan. Heat wheels and enthalpy wheels are also an option, but have similar challenges in most real-world situations.
The biggest challenge with cold climates is making sure the diesel generators start when needed. This alone makes most data center managers skeptical at the prospects of cold-climate data centers.
For a truly efficient solution, the best approach is likely to be heat removal at the chip level and recovery for other purposes. 100F air isn't very useful, but if you can get 150F water off the chip then that heat can often be reclaimed for some other purpose more effectively. If all else fails, 150F water is pretty easy to cool off in a closed circuit dry cooler no matter what the outside temperature.
There is also a lot of work going into direct-evaporative cooling solutions (swamp coolers) for data centers, as well as some other non-compressor based cooling systems. Unfortunately, most of these can work very efficiently for 9-10 months a year, and need a separate system to cool for the remainder of the year. Having two systems makes the payback equation often favor the less efficient solution...

I'm not saying your typical data center is going to put out the same heat as a nuclear reactor. They actually take steps to cool the water, but it's still warmer than it went in.
I think two things will stop these datacenters from going to Iceland: restrictive immigration laws and submarine data cable capacity. Iceland has a total population of about 300,000. They simply can't have a diverse enough IT industry to support setting up these data centers without expats. And without the bandwidth, there simply isn't a point.
