I think you may be correct. I multiplied when I should have divided. I’ve corrected the derivation.

Thanks!

I’ve been following the CO2 per SL Avatar debate with interest across the web and have come across many differing opinions on the topic, not least of which from Nicholas Carr’s original blog post on the subject.

It’s great to see you picking this up and applying some of the findings from within the Carr comments to come up with your new figures and findings.

I had one query on your figures though which I couldn’t understand. If you could help, that would be much appreciated. please forgive me if I have misunderstood/misinterpretted anything!

You say the power consumption of one SL server is 262.5 watts per hour. Also one SL server hosts 64 acres of land so you calculate that watts per acre is 262.5 watts x 64 (totalling 16.8kwh per acre per hour = 147,168kwh per acre per year). My query is that, if the 64 acres share a server using a total of 262.5watts per hour, shouldn’t the power per acre be the 262.5 watts divided by the 64 acres = 0.004kwh per acre per hour = 35.9kwh per acre per year?

As I say, please forgive me if I’ve misunderstood but i’d be grateful if you could explain / correct me.

Cheers!
Steve
