Please define "extended time". I used to have frequent outages from minutes to several hours (I think 8-10 hours max), that is not really a problem if you have as a backup a phone and tethering. If you are talking about a month of outage country wide, the food, fuel for heating, a couple of guns and a thousand bullets may be what you need to survive that, because that will cause massive chaos: our logistic chains cannot work without phone and internet.
