LEDs use very little power, with the cabin in the woods idea I would think its fairly safe to say a log fire is used for cooking, same thing to heat some water for cleaning. Fridge really doesn't use much power if you look for something energy efficient, or just don't have one. Its not like you can't live without it.

I would have thought saying cabin in the woods kinda implies not having some things and living a simpler lifestyle?

Sure, why not. But I was thinking a 4/5G router takes very little power, then a steam deck doesn't take that much either. If that is all you need, few hundred w solar panels and a decent sized camping battery will probably do just fine. You don't need to store a years worth of energy in one go if you can produce more than you use which helps during lower output times.

Then if your employer is mandating return to office, charge the battery there. Make the fuckers pay for it.
