Just built one of these myself. I went NVME M.2 instead of SD Card to avoid data corruption. I know SD Cards are fine if you don’t write to them a lot but if you wanna update or add your own stuff, scares me. Plus NVME is just so much faster.
You find a generator, or solar panels, or wind mill, or water turbine, or a bicycle hooked up to a generator.
If electricity permanently goes out then we’re in a scavenger situation and it is time to start taking apart things that are no longer necessary to build the things that are.

Hey finally a good use for all of those cars, grab the alternators out for small generators (since bicycles are the ultimate apocalypse vehicle: simple, small, easy to maintain and don’t require complex fuels)
Pretty much what Sinthesis said; USB power brick and/or solar panels. Both at the ready and tested. Also got a big ass battery backup that will charge off solar panels.
Eink displays are pretty awesome for this sort of thing, I repuposed a kobo ereader as a household info display and it worked nicely. Those PaPiRus screens look easier to interface with, but a little small for reading wikipedia articles. They’d do in a pinch, but the eyestrain would have me looking for a bigger solution.
Totally, if you want to read or read / sketch then a reMarkable or PineNote would be much better. They’d consume a lot more energy (relatively speaking) but it’s a different use case.

How would you access the info if electricity permanently goes out?

You only need 20 watts of power. One of those dinky fold up solar panels would work. Add a USB power brick for cloudy days.
2W for a RPi Zero with data on a microSD
You’re going to need a monitor as well.
I have a PaPiRus ePaper eInk e.g. https://media.digikey.com/pdf/Data Sheets/Pi Supply PDFs/PaPiRus_ePaper_Web.pdf and even though I don’t know the watts for a refresh but I assume it’s one of the lowest solution you can use.
PS: FWIW if you don’t refresh the display can keep the information on for months, if not years.
