> We are effectively talking about the entire world wide web generating multiple highly secure cryptograph key pairs every 47 days. That is a lot of CPU cycles.

We aren't cracking highly secure key pairs. We're making them.

On my computer, to create a new 4096-bit key takes about a second, in a single thread. For something I now have to do fewer than 8 times per year. On a 16-core CPU with a TDP of 65 watts, we can estimate that this took 0.0011 watt-hours.

Yes, there are a lot of websites, close to a billion of them. No, this still is not some onerous use of electricity. For the whole world, this is an additional usage of a bit over 9000 kWh annually. Toss up a few solar panels and you've offset the whole planet.

but you think think it would take a decade for the entire internet to use as much power as a single AI video?

renewing a certificate does not involve making a new keypair either... It's merely a pair of signatures, one for the CSR and one by the CA.
