My neighborhood has buried lines. We've lost power a handful of times in the last 5 years, usually due to extreme cold(Midwest), or animals getting into power station equipment. Admittedly not day-long outages though. So far the extreme cold cases have been luckily short, so it wasn't a big concern, but if they were longer then I would've been wishing for some sort of backup power for my gas furnace or for a wood stove.

You can bury local lines. But look around and I'm sure within a mile you'll see high-tension lines going across the land, those are very expensive (very) to bury, because they give off quite a bit of heat.
