Facebook Taps Hydroelectric Energy For Swedish Data Center
Facebook announced that its newest data center in Lulea, Sweden, on the edge of the Arctic Circle, which will handle live traffic from around the world, will be powered by hydroelectric energy so reliable that it has been able to reduce the number of backup generators required at the site by more than 70 percent and achieve a power usage effiicency (PUE) of 1.07.
Aside from tapping hydroelectric power, it’s also using the cold Nordic air to cool the thousands of servers that store its members’ photos, videos, comments and other information. Any excess heat that is produced is used to keep its office warm.
