​19. Green Mountain

Green Mountain, based in Norway, has several energy-efficient data centers, but DC1-Stavanger, an underground data center built in a former NATO ammo bunker, is an efficiency king.

The subterranean data center is powered by 100% renewable energy from its own triple-redundant hydroelectric grid, which gives it nearly 100% uptime along with being green.

Stavanger is also passively cooled using nearby fjords.
