The single use of AI to generate that video of Trump licking Elon Musk's feet, used significantly more power than this change will cause to be used over the next decade.

It's great to be environmentally conscious, but if reducing carbon emissions is your goal, complaining about this is a lot like saying that people shouldn't run marathons, because physical activity causes humans to exhale more CO2.

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.

Also you not picking up on the Futurama quote is disappointing.

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?

		No, doing out the math I see I was being hyperbolic. That one AI video used about 100kWh, so about four days worth of HTTPS for the whole internet.

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.

When you generate a new cert you do not generate a new keypair every time.
