You can get small hotplates that can be used during an Ice Storm, or a Camp stove, which we have used. As for Coffee, make it on the electric or Propane Hot plate, or use the propane grill.
Around here, we just become off gridders, when the power goes out. That means keeping 1 gallon jugs of water in the freezer, getting extra water as we can, while the city utility is still pumping water through the lines, having a stock of canned foods, that do not need to be baked in an oven.
Anything in the freezers, they get packed in our ice chests with ice. I have at least six Ice chests downstairs, so that if the power is going to be out for more then 24 hours, I can start packing stuff in the chests with the Ice jugs, then wrap the Ice chests with heavy comforters.
You do get lucky and end up with pockets though that there is power, so it is not like our whole town goes down at once. Especially having two different Electric utility companies in our town.
You just have to plan for the worse case. If your power has only gone out once or twice in a five year period, I look at it that a genset is a waste of money then. Now if power is going out every month for more then four hours at a time, then get a whole house Kohler or Genrac, that you can have switch on automatically. Also good to have a battery bank, that will allow for certain circuits to stay online, for a short period, until the generator comes up to speed and takes over.
