Enter the electric supercycle

They quantify the pain points: Andy reports typical lead times of 3–5+ years for key grid hardware and price increases of about 2–3× versus five years ago, and both warn of a lag before higher equipment costs show up in retail rates — making "affordability" a politically salient issue that could intensify. Despite those short‑term constraints, their thesis is bullish: a set of four building blocks — solar PV, lithium‑ion batteries, electric vehicles (and motors), and power electronics (wide‑bandgap semiconductors like SiC) — form reinforcing flywheels. Examples include EVs scaling silicon‑carbide supply chains that then lower costs/performance barriers for grid inverters and transformer replacements, and microgrid control technologies developed for campuses being scaled up for data centers and EV charging hubs. They also explore second‑order demand vectors: industrial robotics and humanoid/home robots (Andy’s back‑of‑envelope: a humanoid running 5–6 hours/day would use ~3–4× a refrigerator annually), and the possibility that defense and drone markets fund ultra‑high‑energy‑density batteries (ARPA‑E’s 1K and a cited DOD push toward 2,000 Wh/kg) that could later transform heavy transport. The pair converge on the key constraint: long‑distance transmission expansion — new high‑voltage corridors face societal and permitting limits, and there is no simple technology fix — making transmission the long pole in realizing the supercycle. Overall, they paint a picture of acute near‑term bottlenecks and political pressure but sustained multi‑decade upside as technology, capital, and institutional responses compound electrification.
