I just wonder how much energy does it take to serve content over TLS/SSL. Maybe that's another factor to consider when building a "low tech" website.

This feels a bit like counting the amount of coffee you drink when calculating carbon footprint, or a bit like code golf aiming for 1KB of executable size.

Makes more sense to do the 80/20 approach, 20% of work to get 80% of results sustainability wise and the move on to the next.
