The question

If every input to the power system is getting more expensive at once, why is that the setup for a durable investment opportunity rather than a squeeze?

The answer

Because the cost pressure and the opportunity have the same cause. Lubershane argues that electrification’s core technologies feed each other through several reinforcing loops, that those loops are now intersecting with AI and robotics, and that the combination should outlast any individual market segment or business cycle. The cost pressure he calls the gauntlet is the only force pushing the other way, and his closing position is a belief rather than a demonstration: that the flywheels are strong enough to overcome the industry’s inertia.

03The argument

The piece opens on the squeeze. Producer prices for transformers, switchgear and aluminum conductor spiked during the pandemic and have stayed well above general inflation since; combined-cycle gas plants cost about a third more than they did a few years ago; and solar and wind, the technologies whose falling costs defined the previous decade, have been trending upward, with forward contract offers suggesting further rises through the rest of the decade. Demand is climbing at the same time, and he is careful not to hand all of it to one cause: data centers are the tip of the spear, but fresh data he attributes to the IEA’s 2026 global trends review has electric vehicles still adding as much global demand growth as data centers do. This is the gauntlet, a term he says he adopted about three years earlier for a narrow passage the industry has to run for decades. The turn is that the same forces produce a generational investment opportunity. He notes he is not the first to name it, pointing to Kingsmill Bond’s “Electrotech Revolution” and Ryan McEntush’s “Electro-Industrial Stack”, and separating himself from Bond’s version in a parenthesis: where Bond argues for radical acceleration toward a practically inevitable low-carbon future, Lubershane’s stated view is that the energy transition will be a much longer, bumpier ride. His contribution is meant to be the mechanism rather than the label.

The mechanism is three feedback loops stacked on each other. The first is familiar in part: electric vehicles pulled investment into lithium-ion manufacturing, which made batteries cheaper, which made both vehicles and grid storage more attractive, which pulled in more manufacturing again, with cheap solar opening the storage niche in the first place. The element he says is under-appreciated is power electronics, the semiconductor switching that converts between direct and alternating current and regulates voltage, frequency and power flow. Solar drove it first, because panels run on direct current at voltages roughly two orders of magnitude above anything in a phone, which pushed the industry toward semiconductor materials with a wider bandgap than silicon. Electric vehicles then pushed harder, because they convert power repeatedly and are punishing about weight, volume and efficiency. The payoff is manufacturing: larger wafers of these materials translate directly into lower cost, and the evidence for that progress is a chart this note cannot reproduce. Cheaper power electronics then make solar and vehicles better again, which closes the loop.

The second loop is the one that reaches the grid, and it is where the argument is most speculative and most concrete at once. Power electronics already sit where megawatt-scale direct-current systems meet the alternating-current grid, and Lubershane’s claim is that they are theoretically capable of performing nearly any function conventional grid equipment performs, and in some cases, he says, may be the better solution. The illustration is Heron Power, founded by the Tesla veteran Drew Baglino and a portfolio company at his firm, whose first product combines converter, transformer and protection in one unit; the cost, labor and efficiency figures for it come from the company’s own white paper on interconnecting high-voltage data centers. If that works, interconnection gets faster for generation and large loads alike, which means more of both, which means more gauntlet and more demand for power electronics. The longer-run version of the idea, which he attributes to a former colleague’s description of the grid as “cluttered” with equipment accreted over decades, is that power electronics could replace much of that inventory with fewer, more efficient systems.

The third loop is robotics, and it is the part he quantifies himself. Robots inherit the electric vehicle supply chain almost wholesale: batteries, power electronics and high-performance motors are most of the bill of materials for any mobile machine once the processors are set aside. That makes robots another accelerator of the same loops and another source of electricity demand, because, in a phrase he quotes without attributing it, “autonomy favors the electron”. He then sizes that demand with deliberately rough arithmetic, using a robotaxi fleet in one city and a humanoid-scale robot he explicitly does not expect to be the winning form factor, chosen because public data exists for it. The conclusion is the interesting part and it cuts against the excitement: in aggregate this is not an economy-shaking increase in consumption, nothing like the data center boom, and that conclusion rests on a chart the note cannot see. What matters instead is where it would land if the demand arrives at all: out at the edge of the grid, where it could have a large local effect on distribution requirements. Robotics, he adds, should also help the industry run the gauntlet by cutting the cost of building solar farms and transmission lines.

04What you need to know first

Power electronics
Semiconductor-based systems that control voltage, current and power flow. The same kind of switching that represents ones and zeroes in a computer is used here to convert between direct and alternating current and to regulate a power system.
Wide bandgap semiconductors
Materials such as silicon carbide and gallium nitride that tolerate much higher voltages and switching frequencies than pure silicon, and do it with greater efficiency. Their cost falls as manufacturers learn to make larger wafers.
The electricity gauntlet
His own term for the narrow, hazardous passage the power industry has to run: surging demand meeting bottlenecks at nearly every step of the supply chain.

05Details worth keeping

  • He credits Tesla with starting the electric vehicle flywheel, and the Chinese government’s decision to make electrification a national economic and security priority with widening it.
  • Power electronics had been a consumer electronics technology for decades before solar began driving innovation in it around 2010.
  • Waymo fleets so far prefer sporadic fast charging to overnight slow charging, with most of it done in depots where vehicles are also cleaned and maintained. He expects this to change as fleets scale.
  • His Boston estimate rests on a Massachusetts ridesharing dataset he says is unusually detailed; a footnote gives about 47 million trips a year originating in the Boston, Cambridge and Somerville core, which he converts to roughly 3,500 vehicles running 16 hours a day.
  • He notes he barely touched raw materials, and that copper, rare earths, lithium and other critical minerals are also caught up in the same cycle.
  • An embedded card links to his own earlier post on robotics rather than restating the case for it; the argument here assumes that inflection and does not re-argue it.

06Claims worth citing

All figures as stated on 2026-06-01. Equipment prices and robot cost and performance assumptions are among the fastest-moving quantities in the piece. The Heron figures come from the company’s own white paper.

  • Combined-cycle gas plant costs in the United States have risen by about a third in the span of a few years. Gridlab, Energy Futures Group and Halcyon, September 2025, cited by Lubershane
  • Electric vehicles are still responsible for as much global power demand growth as data centers. IEA, “Global Trends Review 2026”, cited by Lubershane
  • Heron’s Link product, used to interconnect 800-volt data centers, is claimed to install for about 50 percent of the capital cost of a conventional data center power train, with a tenth of the labor, and to halve electrical losses against the status quo. Heron Power white paper, cited by Lubershane
  • As an initial rule of thumb, a robotaxi fleet needs one roughly 400-kilowatt fast charger for every ten vehicles. Lubershane
  • Replacing human rideshare drivers in the Boston core entirely with robotaxis would require approximately 140 megawatts of fast charging across a few dozen depots and downtown stops. Lubershane’s own estimate
  • A robot of roughly humanoid capability draws about 500 watts in operation; worked six hours a day it would use about twice the annual energy of an average refrigerator, or about a third of what an electric vehicle driven 10,000 miles a year uses. Lubershane
  • About 60 million Americans work in manufacturing, construction, janitorial services, groundskeeping, material handling, food preparation and healthcare support; augmenting 20 percent of those roles would mean 12 million robots. (Lubershane) He describes their consumption at that point as “two refrigerators worth of electricity per day”, which is a different unit from the annual comparison above; the note records both as written rather than reconciling them.
  • Two conclusions are stated in prose but rest on charts the note cannot read: the manufacturing progress on wide bandgap wafers, and the finding that widespread robot deployment would not shift aggregate electricity consumption much.

07Where it’s contested

There is no second voice, and the piece is not arguing with anyone. What it does carry is one explicit disagreement, several deliberate hedges, and a conclusion stated as belief.

  • He parts company with one of the framings he recommends. He tells readers to go and read Bond and McEntush, then says in passing that he does not share Bond’s view of a practically inevitable low-carbon future and expects a longer, bumpier transition.
  • He disclaims the form factor his own numbers use. He says he is not particularly bullish on humanoid robots winning, and uses humanoid data only because it is publicly available, inviting the reader to substitute any robot with comparable manipulation, load-bearing and mobility.
  • The robotaxi rule of thumb is labeled initial. He says charging behavior will almost certainly evolve as fleets scale, and the Boston number is explicitly his own estimate from a single city’s data.
  • The load-bearing assumption is asserted at the end, not argued. He states that the gauntlet is the only dampening force in the cycle and that he believes the flywheels are strong enough to overcome the sector’s inertia. Nothing in the piece tests a failure mode from outside the energy system, such as AI investment disappointing, capital costs, trade policy or materials, which he acknowledges he barely touched.
  • His firm’s interest appears at the pivotal example. The grid half of the argument is carried by a portfolio company’s product and that company’s own performance figures, disclosed inline, and the post ends by asking builders in the space to reach out.
