Bitcoin And Energy Full Picture
Bitcoin uses a lot of energy. That’s true and worth taking seriously.
Estimates put the Bitcoin network’s annual energy consumption at 100-150 terawatt-hours — comparable to the consumption of a medium-sized country like Argentina or the Netherlands.
The honest response to that fact isn’t to minimise it. It’s to put it in context.
Bitcoin’s energy use is less than gold mining. Less than the global banking system’s combined infrastructure — data centres, offices, ATMs, branches, card networks. A fraction of global air conditioning. The country comparison is vivid but slightly misleading — countries consume energy across all sectors simultaneously, while Bitcoin’s entire consumption is doing one specific thing: securing a global monetary network.
The energy mix matters too. Studies consistently find that Bitcoin’s electricity comes from 50-70% renewable sources. Not from environmental virtue — from economics. Miners seek the cheapest power. In many parts of the world, the cheapest power is stranded renewable energy that would otherwise go to waste.
And the energy isn’t waste in the way critics sometimes imply. It’s the security model. As covered in Part 7, proof of work requires real energy expenditure precisely because that makes attacks expensive. The energy is the security deposit that makes Bitcoin’s history immutable.
None of this means the concern is wrong — it just means the full picture is more interesting than either side usually admits. The next few days go into the details that make the picture more nuanced than the headline debate.
Tomorrow: Bitcoin mining and renewable energy — why they align more than you’d expect.
