Account for the cost of cooling #416

Closed roarin-roran closed 11 months ago

roarin-roran commented 1 year ago

Description

it seems that the costs estimated are based on the direct energy usage of hardware but in data centers a significant fraction of the energy usage comes from cooling requirements.

are approaches to this mentioned anywhere I'm missing?

if not, this should probably be discussed and estimated

Hello, We just added in version 2.2.3 an option to set the datacenter PUE for that purpose : https://github.com/mlco2/codecarbon/blob/master/examples/pue.py

roarin-roran commented 1 year ago

fantastic!

should this be documented here: https://mlco2.github.io/codecarbon/parameters.html

seems to cover @track_emissions, but not the variables in the example.

also, how is this cooling cost estimated/measured? we're considering using code carbon for scientific purposes where we'll need to detail that.

Hello, the PUE is a multiplication factor provided by the user, so it is up to the user to get it from his cloud provider.

Old data-centers have a PUE up to 2.2, where new green one coud be as low as 1.1.

I will update the documentation.
