Quote of the day--from Server Farm wikipedia

According to some estimates, for every 100 watts spent on running the servers, roughly another 50 watts is needed to cool them.^[6] For this reason, the siting of a Server Farm can be as important as processor selection in achieving power efficiency. Iceland, which has a cold climate all year as well as cheap and carbon-neutral geothermal electricity supply, is building its first major server farm hosting site.^[6] Fibre optic cables are being laid from Iceland to North America and Europe to enable companies there to locate their servers in Iceland. Other countries with favorable conditions, such as Canada,^[7] Finland,^[8] Sweden^[9] and Switzerland,^[10] are trying to attract cloud computing data centers. In these countries, heat from the servers can be cheaply vented or used to help heat buildings, thus reducing the energy consumption of conventional heaters.^[7]
