This is just a quick answer to the letter by Jody Jones and Dan Cather. (http://www.ladailypost.com/content/letter-editor-bury-power-lines-through-or-near-forests).
You cannot ship AC power underground for long distances. The losses are too high.
AC couples both inductively and capacitively to the surrounding environment. That is why transmission lines sit high above the ground.
My company (Tibbar Technologies) is working on a solution to this problem. If you are interested in this, contact me at firstname.lastname@example.org and I will be happy to give you a tour of our facility.
