The Bitcoin Mining Council's claim of 56-60% green energy usage in mining lacks credibility due to methodological flaws. Its self-reported survey, covering only 32% of miners, relies on voluntary data without transparent verification, raising bias concerns. Independent studies, like Cambridge's, estimate renewable use at 37.6%, highlighting a significant gap. Miners are incentivized to seek cheap, often fossil-based energy, undermining the council's figures. For instance, coal-heavy regions like Kazakhstan and reactivated U.S. fossil plants contradict the green narrative. While some miners use renewables, the council's data overstates the trend, lacking standardization and external validation. True sustainability requires mandatory disclosures and a shift from proof-of-work. Until then, the council's claims remain questionable, serving more as industry PR than a reliable benchmark for Bitcoin's environmental impact.
