It's almost COP time, which means another website review! This year I'm focusing on the controversial Low Carbon Version of the COP28 website, and looking at how it has been implemented.
My most recent writing on sustainable web development, performance tips for websites and apps, as well as a few other musings.
How much power does loading a JPEG, WebP, and AVIF image consumer on a user's device? In this post, I've used the Firefox Profiler to run some unscientific tests in the hopes of finding out.

A conversation from the ClimateAction.Tech community about self-hosting a website on a solar powered Raspberry Pi.
A small Eleventy plugin I built at the end of February 2023.
