Via Nicholas Carr's Rough Type: view this blueprint for Google's massive facility at the Dalles together with commentary in March's Harper's Magazine. 

I was surprised to see in the commentary that Google is planning a data center in Lithuania and a little research suggested that indeed it is.

The commentary in the article, however, is mistaken in suggesting that if Google moves to Lithuania it will be tapping into a grid that is largely nuclear.

This is unlikely. The nuclear power plant at Ignalina is ceasing operations in 2009, a closure that was a condition of Lithuania's EU accession, notwithstanding that nuclear power was the country's single biggest export. New plants are being planned, but only in the broadest sense.
