Bitcoin's Energy Consumption - Waste or Opportunity?
So... Bitcoin's using all the electricity and killing the planet, right?
I gave a lecture about Bitcoin's energy consumption and its effect on the environment, as part of our renewed, relocated Salon lectures. These are my speaker notes.

I generated an audio conversation about this lecture using NotebookLM.
Two AI hosts, one of them walking through the session as if they'd been in the room. Then I spent way too many hours editing it. Transcribing, cutting, re-cutting, syncing it back to the slides. The result isn't AI slop. It's a produced episode.
What I didn't expect was how much the format adds. Having two hosts discuss and dissect the material, highlight what stands out, and build on each other's reactions brings a dimension the slides alone can't. It's a different way into the same content.
In this eye-opening deep dive, hosts Alice and Bob break down a fascinating presentation on Bitcoin's energy consumption and its surprising relationship with renewable energy.
While Bitcoin has faced criticism for its electricity usage, this conversation explores how mining operations are increasingly powered by renewable sources, can monetize otherwise wasted energy, and might actually accelerate the clean energy transition. From reviving century-old hydroelectric plants to capturing methane from abandoned wells, discover how Bitcoin's economic incentives are creating unexpected environmental opportunities.
This podcast challenges the simplified 'Bitcoin is boiling the oceans' narrative with a more nuanced perspective on Bitcoin's relationship with our energy systems. Whether you're a Bitcoin skeptic or enthusiast, this conversation will give you a fresh perspective on one of the most controversial aspects of the world's first distributed digital monetary network.
The lecture covered a lot - history, energy, economics, and some very unexpected oil field engineering.
But let's bring it all back together.
What's really happening here?
What does Bitcoin's energy use actually mean - in context?
And why might it not be the problem we've been told... but part of the solution?
Despite the headlines, the majority of Bitcoin mining already runs on renewable or low-carbon energy.
Independent studies estimate the figure at over 50% - and rising.
Not because of regulation or ESG pressure - but because it's the cheapest power available.
For an industry obsessed with margins, that's all the incentive it needs.
In places where energy is scarce, expensive, or unreliable - Bitcoin mining can do more than turn a profit.
It can help fund microgrids, extend access to electricity, and support communities that have been left behind by the traditional financial system.
With just a satellite connection and some hardware, people gain a foothold in the global economy - and the energy beneath their feet becomes a tool for inclusion, not just extraction.
Bitcoin mining doesn't just consume energy - it pays for it.
And that turns it into something rare: a buyer of last resort for energy projects that wouldn't otherwise get built.
Wind farms. Solar grids. Micro-hydro in the mountains.
Mining helps them pencil out - by turning excess electricity into revenue from day one.
That's not just efficient. It's a financial engine for clean energy.
Bitcoin's energy use isn't simple.
But neither is the world's energy problem.
What we've seen is that mining can be wasteful - or it can be transformative.
It all depends on how we choose to use it.
Thank you.
