Iceland Woos Data Centers As Power Costs Soar
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.)"
I would suggest locating data centers in a cool climate where farming is popular. Pump the waste heat from the data centers into greenhouses that can surround the data center. Now that waste is helping to grow food.
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.

You'd have to have a very cheap and very power inefficient server to come even remotely close to their claims of half of the cost of the server on power. An elbaso HP Dl360G5 costs $1600. It will use about 300W at typical load, but lets call it 250W to make the numbers easier. Double this for inefficient cooling and power conversion in the UPS (this is overly costly but makes up for underestimating power usage) so 500W. There are 8,760 hours in a year so 4,380 KwH, you'd have to pay $.20 per KwH to reach their figure, this is over twice the US national average. Prices where you'd want to put a datacenter are closer to $.06-$.08 per KwH. My average server cost closer to $7,000 with battery backed RAID card, dual fast drives, dual CPU's, 4GB memory, 3 year 6 hour repair contract, etc. Even powering that kind of servers off diesel generators fulltime it would have to draw ridiculous amounts of power to cost half it's purchase price in electricity every year.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
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 certainly don't think heat pollution will be a concern. Gigawatt size coal plants and nuclear reactors have to worry about heating nearby rivers, but in this case we are talking about the additional load to run datacenters heating the Atlantic Ocean. A 1 GW electric power plant will typically reject 2 GW thermally (which is a lot of local heat). But 3 GW is a lot of power to be generated in one spot. The renewable energy sources of Iceland certainly don't generate anywhere near that much power per unit area. And the heat rejected from datacenters will be trivial and widely distributed.
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.
