IMO, some of the best emergency equipment you can have would be an old-school white gas Coleman lantern and a white gas Coleman stove.
The lantern gives you a tremendous source of both light AND heat. A single lantern will keep a moderate-sized room comfortably warm.
The Coleman stove gives you cooking, of course, but also it gives you the ability to boil drinking water which often will be necessary even with city water in the case of a power failure.
The white gas has an indefinite shelf life, and a few gallons I estimate will keep us going for up to a week if necessary. We haven’t had a big ice storm in the Cities for about 20 years, but one good ice storm can make things really uncomfortable for several days if you’re not prepared.
