Those utilities are fairly easy to track in a way that digital services aren’t. Lights in my home consume energy at a consistent rate. Ditto for water coming out of the faucet; if I open it more, I can see it moving more water and costing more.

On the web, it’s not clear that one website is being massively more wasteful than another. From your perspective you’re engaging in the same behaviour (opening a website) but for reasons outside your control you may be spending more than intended.

I remember not having unlimited internet traffic at home and always having to worry. These days, I pay a flat monthly fee for internet access.
