It's very rural and if you can't drive you're stuck. Walking to the closest building or sometimes even a neighbor can be impossible in inclement weather.

Power lines in much of the US are aboveground (as in, not just long-distance transmission lines but the ones going to each house) and snow causes tree limbs to fall and lines to come down.

Each outage might only affect a few people, but where I live there were over 1000 individual incidents within one day last week, so it can take days to repair all of them.
