[Noisebridge-discuss] Carbon offset/energy usage calculators for computers and web traffic?

[Andreas]

Looking through my Internet statistics I was shocked to learn how much
traffic my Amazon server farm uses -- hundreds of GB per month.  That
brought me to calculate my energy usage to purchase carbon offset
packages, but I couldn't find an easy online calculator for

- determining my small/medium EC2 instances energy usage
- a calculator for determining how much energy x GB of Internet traffic consumes

Basically, I would like to have a green consciousness, but don't have
time to research and calculate this myself.  Surely there must be
others with the same problem.  Any ideas?
