Thanks Louise for doing this. Nathan said I would enjoy this and it really was excellent.

You are preaching to the recently converted here, but made so many great points in a short time.

I now really like having the environmental angle to boast client conversations about UX and SEO. It also helps justify spending a little more on building a cleaner site in the first place... and with eliminating who I should not work with.

I had not hear of this before:

My old (not so efficient) WP sites did fine (Digital Ocean servers). I got a fail on a much lighter static site on Netlify (running on AWS).

As you indicated, there are not great tools out there for this and there really should be.
