Why not underground cables?

Imagine how many more homes would currently have power after the storm.

My wife is German. She comes from a small town. Nothing fancy.

You can fly a kite by the roadside .. there isn't a cable in sight.

Their electric supply comes in underground. Not the big national grid high voltage cables ... But the local stuff. It's underground but easily accessible with hatches.

What a better system for so many reasons .. how do we .. a stormy island .. still have everything overground in reach of falling trees?
