which is somewhat out of date, we use about 45kW of electricity
continuously at our Florida colo. According to the 1999 figures here:
the South Atlantic region of the US generates CO2 at a rate of 1.342
lb/kWh, so that works out to about 20 tonnes of CO2 per month.
Some carbon offset prices:
If we assume a mid-range carbon offset price of $10 per tonne, then that
would be $200 per month. This is for the Florida colo alone, and it
doesn't include sq31-50 or the new 2x4 core apaches.
I believe the power itself costs quite a bit more than that, which is why
we carefully consider the energy efficiency of bulk server purchases.
