So no, there is nothing green about it and it's just one guy wasting tons of electricity because he affords to do so, as vapourminer said, a few of Tesla's clients got a free lifetime supercharger when they bought their car.
That's true at the moment, although that's why I said that in the future we might actually benefit from this sort of technology. Electricity can be generated via green energy, mining resources can't. Obviously, to be able to do it we'll need to use our existing resources. However, utilizing things like solar, and hydro plants could potentially increase the amount of green energy being used. The way the world is going, there's enough funding for this to become a reality.
Again, we aren't any where near it, and I do think the closer we get to it, the quicker this green energy buzz word will sort of die down. However, I do expect massive amounts of progress in terms of converting a lot of places to green energy.
Bitcoin, and other industries will benefit from that, and we shouldn't really be hostile to the idea. It's the best approach, it's just everything has been blown out of proportion, especially when it comes to the amount of energy Bitcoin uses in comparison to other industries.
