My bubble: Bitcoin's energy consumption (which is high) has interesting properties which we believe will encourage and support clean energy development for reasons X,Y,Z

You: Nope. Wasteful.
There is no productive conversation to have here
People twist themselves into knots trying to justify the unjustifiable. The "trust" mechanism Bitcoin uses is hugely wasteful, with very small tangible (rather than hypothetical) benefit.
There is also the possibility the author would teach you something, since he started with the exact same position you have. At the very least wouldn't it be interesting to see why he had a change of heart (whether it be greed, wishful thinking, or maybe something you haven't considered)?
