One of our clients forwarded a study (with a comprehensive reference lsit) into the energy use of the information economy. It makes bold statements such as:
- "the ICT ecosystem now approaches 10% of world electricity generation" [sic - should be uses?] "and about 50% more energy than global aviation".
- Tablets, phones and TVs are much hungrier for energy than data centres (see page 4, link below).
- The amount of data being consumed is now measured in Zettabytes (get your head around that). And all of this is mostly powered by coal.
Any guesses as to which Tech company is most dependant on electricity from Coal? Then check out the graph on page 6. This is a hefty tome but a must read for anyone concerned about the energy efficiency of IT. You can find it here .
