It seems kind of primitive to have power lines just hanging on poles, right?
Bit unsightly too
Is it just a cost issue and is it actually significant when considering the cost of power loss on society (work, hospital, food, etc)?

There’s a pragmatic reason too. Power lines and transformers need constant maintenance. When the line fails somewhere, it’s easier to access when you don’t have to dig, and also less disruptive.
Also, they’re up high because people in general are dumb af and will fuck with them if they’re within reach.
Power lines need way less maintenance if you bury them.
Orders of magnitude less maintenance.
its likely becauses it protected from damage by the ground/concrete, and wear and tear from weather.
The cost to reach them to diagnose and replace outweighs the decreased maintenance. Digging is really expensive.
I was in a suburb once that had the lines running in an accessible plastic rectangle running between the sidewalk and road and it seemed pretty brilliant
Which is a solution for a limited area where the extra cost and longer install time might be deemed worthwhile, but when you want to run miles upon miles of lines then it is less feasible.
I think it’s probably reasonable to run the large transmission lines open because they’re huge and easier to landscape but most people live in dense suburbs or cities (where they’re already underground)
And most dense suburbs just have their power polls waiting precariously under trees which requires additional tree maintenance and is expensive to fix after a storm
I agree there are places it wouldn’t make sense but it seems like nearly all the places where it would make sense still havnt bothered (cost, I know)
Companies have done the math, repeatedly.
If underground cost less even over a 5 year period, they would be doing it.
In a dense urban environment you are wanting retrofitted lines run through terrain already full of concrete, water lines, and other urban features. That would take a lot of coordination in design and still likely miss things (which means more time and money on redesigns). It also means a long installation time which means extended disruption to the area.
These sorts of underground lines are easier to run in totally fresh new construction, but then again, it runs into servicing issues and extra expense.
Assessing and fixing underground lines is much harder, more expensive, and disruptive.
