And have to dig up even more earth using even more big machines? If you did a 50ft power line underground, that’s 50 ft of earth that has to be dug up, not to mention what happens whenever something inevitably goes wrong and you have to dig it all up again. Then you also have to bury transformers, which means you need to cool them.
There’s many, many good reasons that we use power lines over burying them. Mostly, power lines are so significantly cheaper and easier that it’s not even comparable. I’ve seen the bill when a buried fiber line gets broken. It is crazy expensive.
