This is a really interesting, yet logical move for Google. This would really help them to further leverage their (smart) PowerMeter tool and it makes their partnership with GE that much more strategic. I also think that they could start to lay dark fiber that they would eventually use to build their own network (that is supposed to be 20 times faster than the current), which would essentially become a new Internet.
"In a unanimous vote, the Federal Energy Regulatory Commission has approved a request from Google, Inc. to buy and sell electricity, granting Google “market based rate authority.” But like many new ventures the Mountain View, California-based tech giant embarks on, they’re not quite sure where they’re going with it yet, or what they’ll do with their new authority. Google has no immediate plans to buy or sell electricity, but reportedly made the move to better position itself to manage its own energy and to have more access to renewable energy."
