53. Robert Mullin - Upstream Downstream

·57 min·13 clips

The setup is plain enough. Renewable ambition may sound clean, but this conversation keeps hauling it back to rocks, permits, drilling, and economics. Subsidies still matter. The guest says renewables have not yet shown they can reliably earn economic returns without serious support. Then the mineral math gets awkward. Building the renewable systems people are talking about means pulling far more lithium, copper, nickel, zinc, and rare earth elements out of the ground. Copper is the cleanest example. The guest pushes back on the easy answer that plenty of copper exists somewhere. Existence is not supply. Like gold in the ocean, a resource can be physically present and still make no economic sense to extract. That gap separates headline abundance from projects that can get permitted, drilled, built, and brought online. The history matters too. A Chinese and Asian industrialization boom from roughly 2000 to 2010 drove a huge natural resources buildout. Capital spending kept running into 2014. That wave created the overcapacity that made resources painful from 2010 to 2020. Now the production need has shifted again. The hard part is that the easier projects were more likely to get built during the last boom. What remains is not nothing. It is a shelf of difficult assets, held back by permitting, jurisdiction, grade, depth, remoteness, or economics. So the trade is not simply renewables versus natural resources. It is renewable systems versus the materials they need, and those materials may not show up cheaply, quickly, or easily.

As heard by us

A skeptical, economics-first look at why the energy transition keeps running into geology, permitting, and capital constraints.

This episode takes a clear-eyed look at the awkward math behind the energy transition. Copper, lithium, nickel, permitting, capital cycles, and the gap between what sits in the ground and what can actually be mined all get treated as hard constraints, not talking points.
