That is true and addressed as an issue in the blog (to be transparent). It's a problem low-tech magazine also faces and wants to improve.
I'm in an apartment and my solar is in a terrible spot. The solar array is crazy over-sized to provide enough power to sustain the Pi and charge the battery.
I think it's easily doable for a person with good solar to put the entire chain Pi-switch-modem on solar.
I did not mean the blog owner’s equipment which the author covered in the post. I meant the ISPs and transit providers in between the server and any user wanting to see the blog. There is not much we can do to control the power sources in that .
While undersea cables and ISP network switches etc perhaps are efficient on a per packet level, they consume substantial power I would imagine .
