I have got electric torches with LED lights, a recharchable battery and a generator which could be loaded with a crank lever. The loading of the battery is noisy and takes quite some time until you have enough the battery loaded enough to use the torch. I used it during a blackout some time ago - useful.
In the past people heated one! room in the house - usually the kitchen, which could be also a used as room for indoor working.
I found that a (horse) stable in winter is still relatively warm in winter. So many people in a small room may heat it a bit but do not forget that you need air for everyone. Too much CO2 / CO kills.
You sleep better when not shivering. So enough blankets or a sleeping bag may be useful. About 70 years ago my family warmed their beds in the unheated, cold sleeping rooms with bricks, which were heated in the wood stove (cooker) in the kitchen. The bricks were put into a towel and were moved from time to time to make the whole bed war. This was done some time before going to sleep, so the beds were warm when going to sleep.
My Grandmother had a rack on the balcony to put food on it in cold weather - some sort of low-tech fridge. You just need to take care that animals do not get the food before you. Before we had electic fridges there were "fridges" with a large stick of ice - ice boxed. The large ice sticks were sawed out of lakes or pond in winter and kept in storage with sawdust between them.
