The Energy Politics Forgot

About 6,000 kilometers straight down, the Earth's core sits at roughly the temperature of the surface of the Sun — a ball of iron kept molten by radioactive decay and by primordial heat still leaking out from the planet's violent formation four and a half billion years ago. It has been radiating that warmth outward, continuously, the entire time mammals have existed. It will keep doing it long after we're gone. You are, at this exact moment, perched on top of an effectively inexhaustible power source, and you have probably spent more energy this year being angry about other people's energy opinions than you would ever need to pull out of it.

This is the quiet comedy of geothermal: it's the renewable nobody had to invent. The heat is already there. We just have to drill toward it and not get in our own way.

And here's the genuinely strange part. Geothermal is gaining real, bipartisan traction in American politics right now — and it's doing it precisely because it doesn't register as "green." Democrats back it because it's renewable and carbon-free. Republicans back it because reaching the heat requires drilling, and sometimes fracking — the exact muscle and machinery the fossil-fuel industry already owns. As the NeuroLogica writeup put it, both sides agree geothermal is awesome and are all in. It's an energy source that decarbonizes the grid while wearing a hard hat instead of a hemp shirt.

That hard hat is the deeper reason it reads bipartisan, and it's worth naming plainly. Geothermal doesn't ask the fossil-fuel industry to die — it asks it to redeploy. Same rigs, same drilling crews, same political muscle, pointed at heat instead of hydrocarbons. And that turns out to be the quiet rule of every energy transition: the ones that let incumbent power reconfigure itself tend to get through; the ones that demand incumbents be destroyed get fought to a standstill. Solar and wind asked the old order to step aside. Geothermal hands it a new job. No wonder it slips clean under the culture war — the culture war is a fight over who loses, and here, on paper, nobody has to.

The numbers are still humble. Geothermal supplies about 0.4% of US electricity and 0.3% of the world's, and roughly 93% of the American share comes from just California and Nevada — the lucky few places where the planet's heat conveniently rises close to the surface. To actually matter for decarbonization, that has to grow by one or two orders of magnitude. The bottleneck is depth. The good hot rock — 150 to 250°C — is everywhere if you go deep enough, but drilling is brutally nonlinear: a couple million dollars to reach 2 kilometers, around 20 million at 5, more than 100 million at 15. The deeper you want the heat, the more the planet charges for it.

So people are getting clever. One company, Quaise, wants to drill with millimeter-wave energy — gyrotron beams that literally vaporize rock instead of grinding through it — aiming for a one-kilometer test bore by 2027 and a working plant in the mid-2030s. It might not pan out; research rarely keeps its promises on schedule, and the honest answer is that widescale geothermal is probably decades away. But the direction is unmistakable, and the direction is down.

Here's what I find quietly beautiful about it. Geothermal isn't winning yet — four tenths of a percent of the grid is a rounding error, and its real gatekeepers are drilling depth and capital, not politics. But it's the rare decarbonization play with no political headwind to fight. It isn't beating the current; it's positioned outside it entirely — riding a wave the culture war can't even perceive. Alignment over force. The surfer doesn't argue with the ocean; he finds the place where its power becomes his. While we burned a generation of attention fighting over the visible five percent of energy policy — the solar panels, the wind turbines, the symbols loaded with tribal meaning — the planet's own heat was sitting underground the whole time, politically invisible, ideologically frictionless, supremely indifferent to which team you're on.

The furnace doesn't care about your priors. It never did. It's just down there, glowing, waiting for us to stop arguing long enough to drill.
