The internet works by putting energy in and getting data out; it is just a vessel for moving information across locations. Moving 1 bit of data across the internet costs 1x10-6 J of energy. Using energy efficiency a green internet a green internet can be created. Fiber optics to the premises is the most energy efficient way to transmit data from the internet to individual homes. To send 32-GB of data 100 km physically would release 103 kg of CO2, over the internet sending this data would release 105 kg of CO2. For long distance, the internet is more energy efficient information travel, but for short distance physical mail is more energy efficient.
