Spring is coming, in a few weeks heat will be more of a luxury than a need.
I have a small generator to run the coal stove (it's a stoker), but won't keep it going full time. I'm installing a wood stove this year, with a cook top.
The bigger concern will be keeping the freezer cold if the power goes out, it's already in the basement, which stays cool year round, but I would surround the entire thing with foam sheets, and make sure the alarm has new batteries in it, fill it with snow or ice while we still have it, and cycle it with the generator as often as needed if the power goes down.
Related to power, as long as we have power at the panel, we will have water in the house (assuming the well pump doesn't take a shit), but I also have a hand pump (which I am pretty happy with, I made it last month)
I have lots of ways to cook food should we lose power, propane, naptha, butane, all different types of stoves, with wood as a last resort.
We should have enough food in the house right now to feed 4 people for at least 30 days, likely 60 days, but it will get boring.
My biggest concern is my youngest, she is a very picky eater. No idea why, we did nothing different with her, she's been picky since she was on the boob (preferred one side over the other and would have a fit if forced to switch).
Peanut butter is what I've stocked for her, she loves peanut butter and milk, but is a real pain in the ass with foods like rice, and has never eaten meat, she's spit it out every time she's ever tried it.
