An anonymous reader writes "The US Federal Energy Regulatory Commission (FERC) on Thursday granted Google the authority to buy and sell energy on a wholesale basis. Google applied for the authorization last December through a wholly owned subsidiary called Google Energy. 'We made this filing so we can have more flexibility in procuring power for Google's own operations, including our data centers,' Google spokeswoman Niki Fenwick said via e-mail. But the authorization also raises the prospect that Google may start to buy and sell energy as a business." Reader angry_tapir supplies a link to the approval document itself (PDF).
