The Internet's (Surprising) Carbon Footprint

There's a great piece in the Guardian today about the internet's carbon footprint. It's something most of us simply don't think about and the impact of it is profound. Here are the highlight graphs:

With more than 1.5 billion people online around the world, scientists estimate that the energy footprint of the net is growing by more than 10% each year. ...
And while the demand for electricity is a primary concern, a secondary result of the explosion of internet use is that the computer industry's carbon debt is increasing drastically. From having a relatively small impact just a few years ago, it is now leapfrogging other sectors like the airline industry that are more widely known for their negative environmental impact.
