“Well, if you want to cover the entire planet, if you want to make sure every single human being has access to geothermal energy, not just a little bit of it, not just a little bit to bathe in hot water, but also to power every single appliance and every single use of modern life, you have to drill 20 kilometers at most, that's 12 miles.”

The claim, plainly

Drilling a maximum depth of 20 kilometers (12 miles) anywhere on Earth provides access to geothermal energy sufficient to power modern electrical and energetic demands.

Assessment

The geophysical and thermodynamic premise of the claim is confirmed by empirical crustal data and established geothermal thresholds. Even in Earth's coldest geological settings—ancient, tectonically stable continental shields and cratons with minimal geothermal gradients (10–15 °C/km, as confirmed empirically by the Kola Superdeep Borehole SG-3)—subsurface temperatures at 20 kilometers reach 200 °C to 300 °C. Standard continental crust reaches 500 °C to 600 °C at 20 km, and oceanic lithosphere exceeds 500 °C to 1,000 °C. Because industrial electricity generation is viable at fluid temperatures starting as low as 75 °C to 150 °C (binary cycle) and 150 °C to 200 °C (flash steam), a depth of 20 kilometers anywhere on Earth provides access to thermal conditions sufficient for electricity generation. Furthermore, the accessible thermal capacity within the upper 20 km exceeds modern global primary energy and electricity demands by orders of magnitude.

Empirical deep borehole data from the Kola Superdeep Borehole (12,262 m, Baltic Shield) measured 180 °C at 12.2 km, projecting 20 km temperatures above 270–300 °C in one of Earth's coldest crustal settings.
Standard continental crust reaches 500 °C to 600 °C at 20 km, well above the 374 °C supercritical water threshold.
Conventional geothermal electricity generation requires only 75 °C to 200 °C, confirming that temperatures at 20 km anywhere on Earth exceed industrial power generation thresholds.
The International Energy Agency (IEA) estimates geothermal technical potential within the top 8 km alone exceeds 300,000 EJ, far exceeding global primary energy demand.

Solar and wind alone would match CO2's ecological harm, says Araque

“I think it would, but the ecological consequences would be just as bad as putting CO₂ into the atmosphere.”

Araque: Only fission, fusion, and deep geothermal can scale to humanity's needs

“So when you look at that, I think there's only three things that can do it. The first one is indeed nuclear fission. As you just mentioned, it has the scalability and the power density to do it. The second one is fusion, which is what the sun does, but it's st…”

Araque: Quaise Can Reach 20-Kilometer Depths to Unlock Global Geothermal

“So we think we can get to 20 kilometers. This is twice as deep as we've ever drilled as humans, and precisely what's needed to make geothermal totally global and ubiquitous.”

Araque: Gyrotron millimeter waves can vaporize any subterranean basement rock

“Anything that's down there in the basement rock Can be vaporized through this. if you try to vaporize a metallic wall, it's not going to work, but there's no metallic walls down there. So, so rock vaporizes.”

Araque: Millimeter-wave drilling creates vitrified glass walls that stabilize deep boreholes

“So when you're drilling the energy, you use temperature to stabilize the hole, and it basically keeps itself open. It creates a glass wall that's very, very, very strong. We've seen this in the lab.”
