Where's the power coming from to scale like that? If Facebook is relying on power from the Columbia River for their data centers, they better talk to the tribes and the salmon. Those dams are failing and many parties in the Northwest want to see them removed.
A better bet might be for them to scale up in Utah and harvest methane from waste to generate power.
Because Utah has a lot of methane? I'm not quite following. I'd think methane production would be greater in a cow state like Iowa or Ohio than in a desert state like Utah? joke
Utah's power grid is primarily coal fired, but they use a fair bit of natural (methane) gas as well. [1] Utah has a couple of major hydroelectric dams (glen canyon, flaming gorge), and the use of solar and wind are on the rise.
NSA is building a major data warehouse in Utah; one of the considerations would have to have been cheap power. I'm guessing the Columbia river produces cheaper electricity than pretty much anywhere else, but Utah has very diverse (and affordable) power production overall.
