A look at efforts by bitcoin miners to use green energy sources, including the voluntary Crypto Climate Accord framework signed by 180 companies in April

Context & Ripple Effects
The green-mining push has been building since Square committed $10M to renewable bitcoin mining in late 2020, but the industry's footprint problem kept resurfacing: a fossil fuel plant in New York was restarted to mine crypto, prompting state legislators to weigh a three-year moratorium. Miners responded by courting baseload alternatives — TeraWulf and Compass Mining began partnering with nuclear power plant owners amid environmentalist criticism.
This WSJ piece lands after 180 companies signed the voluntary Crypto Climate Accord framework in April, framing the accord as the industry's collective answer. Whether voluntary pledges can hold off both activist pressure and regulation is now the live question.
First-order effects
- Signatories of the Crypto Climate Accord gain a reputational shield, while miners like TeraWulf and Compass Mining that moved early on nuclear deals can point to concrete clean-energy sourcing rather than just commitments.
- Miners still running on restarted fossil plants — the New York case most visibly — are now contrasted against the accord's membership, splitting the industry into pledge-takers and holdouts.
Second-order effects
- Critics are unlikely to accept voluntary frameworks at face value: Greenpeace and other groups, funded by Ripple co-founder Chris Larsen, later ran ads in the NYT and WSJ highlighting bitcoin's environmental impact, testing whether the accord blunts or provokes that pressure.
- Regulators treat the accord's existence as evidence the industry can self-regulate only partially — New York's proposed mining moratorium preceded it, and the federal government later attempted its own mandatory energy-use survey before settling with Riot Platforms and an industry group and cancelling it.
Third-order effects
- If voluntary clean-energy pledges become the price of operating, mining consolidates around players who can secure large-scale low-carbon power — nuclear owners and renewable developers gain a new class of industrial customer, mirroring how compute demand is reshaping energy siting generally.
- The pattern sets up a durable contest over social license for energy-hungry compute: voluntary industry frameworks on one side, activist campaigns and regulatory surveys on the other, with each side citing the other's moves to justify escalation.
The trend: Bitcoin mining's environmental fight is shifting from where miners plug in — fossil restarts versus nuclear and renewables — toward who governs the industry's energy claims: voluntary accords, activists, or regulators.
