- "emailing a 4.7-megabyte attachment — the equivalent of four large digital photos — can use as much energy as it takes to boil about 17 kettles of water."
- "The total amount of digital storage worldwide is approaching 1 zettabyte (10^21 bytes), or 1 million times the contents of the Earth’s largest library."
- "Currently, that information is archived on equipment with a mass equivalent to 20 percent of Manhattan."
- "Global data storage is expected to reach 35 zettabytes by 2020...."
- "The information industry already accounts for approximately 2 percent of global carbon dioxide emissions. That’s the same amount as the airline industry blasts into the atmosphere."
They don't say how much energy is used to route information versus to store information, but I would guess that the latter dominates. What will a 35x increase mean for energy consumption?
