I don't think this really has anything to do with the cloud. On-premise hardware still needs cooling, and is arguably harder to cool as there are fewer economies of scale on cooling infrastructure. Dedicated "bare-metal" machines are just in regular data centres so no difference to the cloud there. I think data centre locations will still be chosen on two factors: distance to customers, and cost of energy. It's just that operators will be looking for cheap energy. Iceland is good because they have a lot of geothermal energy, not because it's cold.
