CSS { In Real Life } | Web Sustainability and the Ethical Dilemma

But is it always the case that faster websites are greener websites? We reluctantly have to consider another facet: if making a website for a car manufacturer faster leads to an increase in the number of cars sold, can we really say that our website is greener?

This is very timely for me, given that Clearleft is currently engaged on a project that’s making me decidedly queasy for this exact reason—the success metrics of the project would be net negative for the world.

How creating a Progressive Web App has made our website better for people and planet

Creating a PWA has saved a lot of kilobytes after the initial load by storing files on the device to reuse on subsequent requests – this in turn lowers the load time and carbon footprint on subsequent page views, making the website better for both people and planet. We’ve also enabled offline access, which significantly improves user experience for people in areas with patchy connections, such as mobile users on their commute.

5G Will Definitely Make the Web Slower, Maybe | Filament Group, Inc.

The Jevons Paradox in action:

Faster networks should fix our performance problems, but so far, they have had an interesting if unintentional impact on the web. This is because historically, faster network speed has enabled developers to deliver more code to users—in particular, more JavaScript code.

And because it’s JavaScript we’re talking about:

Even if folks are on a new fast network, they’re very likely choking on the code we’re sending, rendering the potential speed improvements of 5G moot.

The longer I spend in this field, the more convinced I am that web performance is not a technical problem; it’s a people problem.
