Patrick Boyle enters this debate at its most contentious point: the claim that Bitcoin could actually help save the planet. He doesn't dismiss the possibility outright — instead, he systematically dismantles the argument by examining what Square and ARK Invest actually published, then checking whether their numbers hold up against real-world data.
The piece immediately establishes stakes that even crypto-skeptics might find surprising. "A single bitcoin transaction uses the same amount of power that the average american household consumes in a month," Boyle writes, "which is around a million times more energy than a single visa transaction consumes." That's the kind of comparison that makes you sit up straight — and it's followed by an even more jarring admission: "bitcoin mining operations worldwide are reported to consume energy at around the annual domestic electricity consumption level of the entire nation of Sweden."
This is where Boyle's analysis gets genuinely useful. He doesn't just report the numbers — he interrogates the green case itself, pulling apart Square and ARK Invest's paper with the precision of someone who actually read their Excel model. The result isn't a polemic against crypto; it's something rarer: a careful fact-check of one of the most optimistic environmental arguments for Bitcoin.
The Model That Says Six Times Everything
Boyle makes the core argument accessible to anyone who's ever wondered why tech investors get so excited about "clean energy" narratives. He paraphrases their thesis: miners are flexible, location-agnostic, and can redirect power where it's needed — essentially acting as a uniquely adaptable buyer of last resort.
But then he tests whether this holds up. The paper projects that crypto miners could supply "just under today's energy needs by generating nearly six times the grid's full demand level of power" — which is mathematically aggressive. He notes, with evident skepticism, that "they showed that a system like this can meet 90 percent grid demand with only one third of the capex being spent on crypto mining."
You're mostly in the power generation business but to generate enough power to supply the grid you have to generate six times the energy that's being created today — and five sixths of that is used for crypto mining.
This is Boyle's sharpest insight: the model essentially assumes away the entire problem. It projects a future where green infrastructure covers the planet, batteries store everything perfectly, and somehow this produces more energy than we currently use — while primarily serving crypto miners rather than actual grid demand. The circularity he identifies is devastating: "the core idea that they have is that money made from crypto mining will make more green energy projects viable" but only "so much of this energy will then be used for mining crypto with only the leftovers being available for charging teslas."
Where Bitcoin Actually Lives
The piece's most persuasive evidence isn't theoretical — it's geographical. Boyle points out that despite the rosy projections, "around 70 percent of the bitcoin mining happening today takes place in China where electrical power is cheapest" — and "around 80 percent of China's electricity comes from coal burning power plants." Russia and Iran are also major mining centers, with grids that aren't "a whole lot greener" than fossil fuel-dependent systems.
This isn't a minor inconsistency. It's the fundamental gap between the green narrative and reality: the places where Bitcoin actually runs today are predominantly powered by coal, not solar or wind.
Critics might note that Boyle's critique focuses heavily on Square and ARK Invest's assumptions without fully exploring whether flexible mining loads could genuinely provide grid services — a legitimate argument some engineers have made. He acknowledges this possibility but doesn't resolve it, instead letting the data speak through his paraphrasing of where miners actually operate today.
Bottom Line
Boyle's strongest move is turning the optimistic green case into a question about actual energy flows. The paper promises a future where crypto mining finances clean energy; Boyle finds it's mostly a future where China and Russia burn coal to power Bitcoin — with only leftovers for the grid. His biggest vulnerability is that he doesn't fully engage with whether flexible loads could theoretically help renewables, leaving the strongest counterargument on the table. But his core point lands hard: when you model out exactly what these projects require, you find they're mostly mining operations dressed up in green language.
