I just got back from the Bitcoin Energy Summit in Lisbon and I have a question that won't leave me alone. First some context: Bitcoin mining is now stabilizing the grids of 7 nations, 4 agencies (including the Spanish Govt and the World's largest energy policy association) just called for more flexible demand being critical to the resilience of the grids of the future - and Bitcoin mining is the world's most flexible load resource by an order of magnitude. So in light of this my question is this: why is 95% of the Bitcoin adoption conversation about Bitcoin-as-money when Bitcoin-as-energy is already deployed on grids across three continents? Is it possible that energy is the Bitcoin usecase that paves the road for mainstream acceptance of Bitcoin in the West? I've been in this space for four years now. When I started, the conversation was "bitcoin mining wastes energy." A group of Bitcoiners including Troy Cross changed that. Then it became "ok maybe it doesn't waste energy, but it's not useful." @gladstein , @jack and others changed that too. But here's what I noticed in Lisbon. Three separate European organisations - the European Bitcoin Energy Association, Free Madeira, and the Institut National de Bitcoin in France - are all independently converging on the same conclusion. Rachel Geyer, Chair of EBEA said energy is what will move the needle for Bitcoin in Europe. André Loja at Free Madeira said energy is the most topical issue in Europe right now. Bastien Desteuque, directeur général at INBi (Bitcoin Policy Insitute of France) said they're focusing on mining because France has spare nuclear capacity and that's where the biggest opportunity is. Three organisations. Same conclusion. And that's before you get to what's actually being built. In Sweden, a man I coach runs ASIC hardware that earns almost two-thirds of its revenue from frequency regulation - keeping the lights on, responding in seconds to the need of the grid operator, and helping to stabilize the grid an incredible11,247 times last year alone. (Yes, you read that sentence right). In Lisbon, I watched Kenji Tateiwa present a circular economy where bitcoin mining heat grows tropical fish and the CO2 gets converted to charcoal and micro diamonds. Bastian outlined how France's surplus nuclear energy could be absorbed by bitcoin mining by 2027. The conversation has quietly moved from "does bitcoin mining help grids?" to "how many services can one machine provide?" We've been thinking about this like monoculture - one machine, one function. What I saw in Lisbon is permaculture. The same hardware doing frequency regulation, heat capture, Sats-minting ... and potentially in the near future - voltage regulation (something that would have prevented the 28 April 2025 Iberian Peninsular Blackout. I talked to Bitcoin founders after the keynote who told me the energy thesis had opened their eyes. These are people who worked to advance Bitcoin payment infrastructure, and they hadn't fully grasped this. So here's my question. If energy is already Bitcoin's most mature real-world use case in the West - more deployed than payments, more proven than store-of-value at institutional scale - why are we still treating it as a footnote? What other Bitcoin use case is this far along ... at least in the West? Excited to see what happens next.
