You can't always make modern tech as energy efficient as 'regressive' technology. There isn't always a magical solution that addresses all problems. In my opinion, low-tech solutions are often just simpler, while maybe lacking a bit of convenience. Here's an example, the open source community has spent thousands of man hours developing various note-taking apps. And they're pretty good, usually. I could use something like Foam to manage my notes, learn to use the keyboard shortcuts, figure out how to sync it between my devices, learn every other little thing about it... Or I could just use pen and paper. Which requires no electricity, no computer, is durable and does not have a learning curve to use.
