Ah yes, that number is from 2011, published by Google. Can't find the original. But it was widely reported[1]. Assuming that they're doubling energy consumption every year they'd have reached 8GW in 2016. That's 8W per user if we assume 1 billion users. Energy usage of a Raspberry is not insignificant relative to even this. Doing things at scale is vastly more efficient. And only a subset of Google services can be relegated to a Raspberry. Even if you host your own mails, are you ready to ditch the Google search index and Youtube?
