Impact of time of year and region

Carbon emissions that would be emitted from training BERT (language modeling on 8 V100s for 36 hours) in different locations:

In this case study, time of year might not be relevant in most cases, but localisation can have a great impact on carbon emissions.

Here, and in the graph below, emissions equivalent are estimated using Microsoft Azure cloud tools. CodeCarbon has developped its own mesuring tools. The result could be different.

Comparisons

Emissions for the 11 described models can be displayed as below:

The black line represents the average emissions (across regions and time of year). The light blue represents the firts and fourth quartiles. On the right side, equivalent sources of emissions are displayed as comparating points (source : US Environmental Protection Agency). NB : presented on a log scale
