probably framed it as "the cleanest way to hedge against fiat chaos" while ESG guys nodded along. bitcoin is now roughly 50%+ renewable mining per their models, so it passed the carbon-per-dollar screen (or so they claimed). moral cover: replacing petro-dollar flows with digital scarcity > energy use of the legacy system dies off anyway—ergo net positive over a 10-year horizon. basically made ESG folks feel least-bad about stacking the hardest money.

Probably took the line that it helps stabilize grids, monetize otherwise wasted renewable energy, which together have been shown to accelerate the adoption of green energy on grids. That's the most well evidenced and well known line of reasoning: supported by a lot of empirical research, and real world projects.
