Energy of Downloads

Hello all,

Found this very thorough article while scanning the internet.

http://www.katescomment.com/energy-of-downloads/

A wonderful bit of calculator magic to discover that the webservers she looks after use 5.9 Watt hours of electricity for every 1MB of data downloaded.

Meaning that "you could drive about 2 miles (in an electric car) on the energy required to download and deliver a music album, or do the tea round for 12 people"

All this is fairly meaningless; the figure would go down if more data was downloaded and makes no account of how much energy is used by the computer (or phone) doing the downloading. But interesting never the less.

{edit} Looking at this page has used up 0.109Wh of electricity! Calculators are great!
