You are there and know what probems you would have running electricity to your garage. But I would look at what it would take to have electricity in your garage. With power in the garage , you can have radiant heat, a place to work, power tools etc. And if you add solar panels you can feed power from the garage to the house.

Generally if you use a GFI breaker you do not have to bury under ground cable very deep.
