Good question.

I have seen presentations on internet power consumption and its pretty frightening.
All the spam, porn and twitter-echos add up to the same daily power usage as Germany or similar (IRCC the internet would be the sixth largest 'national' consumer if you classed it as a country).

But most here are strident climate change deniers, so it becomes a moot point.
