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

    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)

    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%20Sheets/Pi%20Supply%20PDFs/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.

    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.
