I saw one interesting video of a guy in UK who is living off-grid with solar panels and he is mining bitcoin all the time.
You don't have to go off-grid and it's much easier to do this bitcoin nodes.
He posted above he is bandwidth limited by his ISP.
But, as I said if you need the 500+GB of block data I don't think any of us have any issues putting it on a drive and shipping it to you so you can avoid much of the initial download.
After that your life is easy so long as you keep up a local copy or 2.
