The costs of energy, equipment, etc. have clearly changed and will vary according to your personal situation, i.e. your energy costs and how good you are at finding bargains on packaging, etc. Still, I think this is an eye-opening comparison.
Individual situations aside, it’s clear that dehydrating and canning are extremely cost-efficient ways to store food. Of course, that doesn’t mean that freezing isn’t a great option either. I mean, if it costs 16.2 cents per pound to freeze something and you can secure the type of deal that I did at a local store about 4 months ago when we got grass fed lamb for about 3.25 / pound, then paying an extra 16 cents per pound still makes the lamb a great deal. Also, there are just some things that lend themselves better to one form of preservation than to another. For example, I don’t wish to can or dehydrate meat or chicken broth, but those items both freeze quite well.
