On December 16th, Google formed a new subsidiary in Delaware known as Google Energy. They then requested permission from federal authorities to buy and sell wholesale electricity. What could Google want to do with this?
In all likelihood, according to Cnet, Google doesn't want to give us free power, but rather they want their operations to be carbon neutral, maybe they want to do some research on the side. In the past, Google has helped to develop power monitoring software, looked at using electric car batteries to stabilize power grids and hinted at getting involved in renewable energy.
In any case, it will be interesting to see where the Silicon Valley giant goes with this one. [Cnet]
