More 2026 trends: Solar costs, oil oversupply, and the startup slump
with Nat Bullard, climate tech analyst and writer; co-founder, Halcyon
In this note
The question
Once you step away from data centers, what do the data actually say about where energy and decarbonization stood going into 2026?
The answer
The episode reaches no single conclusion and does not try to. It is part two of a walk through Nat Bullard’s annual 200-slide deck, it starts mid-conversation, and it ends on the slide title he reused throughout: nobody knows anything. What recurs across the segments is that the data keeps violating the prevailing narrative in both directions, and that where costs are rising they are rising in the parts of the system that the people usually blamed do not control.
03The argument
This is a continuation rather than a self-contained episode. Kann opens by asking to get off the data center subject, immediately concedes that may be impossible, and settles for treating it as a second-order effect; the rest is a tour of numbered slides. Bullard’s stated purpose for the deck is the closest thing to a thesis: regardless of the rhetoric, here is how it actually played out in the data, which is neither as grim as one camp would have you believe nor as triumphant as the other. The opening pair of slides shows what he means. Clean energy equities returned about twice what the broad US indices did in calendar 2025, which he reads as evidence that activity in these markets continues whatever the politics sound like. In the same year, US energy startup investment fell to roughly a quarter of its 2022 level, and from about 7% of all US startup investment to two and a half percent. Public and private capital were pointing opposite ways at once.
The solar segment is the one Kann calls a soapbox, and it carries the clearest reasoning turn in the episode. Module prices keep falling and are cheaper than ever, and yet installed system prices in the US moved the other way: residential down only 3%, commercial up 9%, utility-scale fixed and tracking up 9 to 10%. The cause is everything that is not the module. Engineering, planning and permitting, labor and tariff-inflated equipment prices sit outside the module manufacturer’s business entirely, and Bullard’s sharper point is that they sit outside the developer’s control too, since no amount of development skill changes the landed price of imported equipment. The transformer slide makes the same argument from the supply side. Prices have not come down and if anything are still ticking up, and his explanation is manufacturer hesitancy rather than indifference: nobody wants to commit to inflexible manufacturing capacity while future demand is this uncertain, which is the logic he also sees in gas turbines. Kann pushes back that transformers should be the easier case, being less capital intensive and less of an oligopoly than turbines, and predicts that companies will come solve it. They agree that so far nobody has.
Two of the remaining segments describe places the American conversation is not looking. Oil is comfortably oversupplied, by roughly 5% on the IEA’s start-of-year estimate, which is enough to damp prices and to explain the lack of enthusiasm for re-engaging with ultra heavy sour crude that would need something like a hundred billion dollars of infrastructure investment before it could flow again. Demand is higher than ever and the market still is not screaming for new barrels. Meanwhile Australia was installing about 40,000 residential storage systems a month in the second half of 2025, mostly as add-ons to rooftop solar that households already had, after a government program opened in July; Kann’s arithmetic is that a year at that pace would put batteries on something like 5% of Australian households. And China accounted for about 42% of global passenger vehicle manufacturing in the first three quarters of 2025, a higher share than Japan ever reached in its heyday, while Chinese electric medium and heavy duty truck sales went from 3,000 in 2020 to 81,500 in the first half of 2025.
The forward-looking material is explicitly speculative and the episode marks it as such. Bullard predicts US energy startup investment above $3 billion this year; Kann takes the over hard, guessing at a tripling off the $2 billion base while allowing that he does not expect a return to $8 billion. His reasoning is that energy has been elevated by the conversations around AI and sovereignty and that interest is now coming from a wider and more diverse set of investors. Bullard’s caveat is aimed at his own series: what counts as an energy company is about to get blurry as firms discover or pivot toward energy applications, which he thinks is a good thing and which would also make the number harder to compare year over year. The episode closes on two quotes he picked for the same reason. A Virginia-focused energy economist said in December 2024 that his 2032 data center load forecast was probably off by a factor of two without knowing in which direction, and the head of Instagram said in February 2025 that the industry may need drastically more or drastically less capacity than it thought to build frontier models. Bullard reads both as genuine rather than performative modesty, and Kann lands the plane on the deck’s recurring title: nobody knows anything.
04What you need to know first
- Module price versus system price
- The module is the panel; the system price is everything installed, including engineering, permitting, labor and electrical equipment. The solar segment turns entirely on the fact that these two can move in opposite directions, and did.
- Duck curve
- The shape of net demand on a grid carrying a lot of solar: demand for grid power collapses at midday, then snaps upward in the evening. The steeper it gets, the more a home battery is worth, which is Bullard’s explanation for the Australian storage boom.
- “It’s a 2021 thing.”
- Bullard’s running sub-theme from a prior year’s deck, which he says annoyed people: a set of metrics peaked in 2021 or 2022 and has not returned to those levels since. US energy startup investment is the newest entry on that list.
05Details worth keeping
- Bullard’s front-row example of Chinese auto exports is Singapore, his hometown: BYD held 0.1% market share there in December 2021 and was by far the country’s biggest auto seller four years later.
- He stresses that China also exports millions of internal combustion vehicles. EVs are what the US and Europe notice because that is what shows up there, but low-cost and fairly high-quality combustion exports are part of the same footprint.
- His open nth-order question: as new car prices rise, what happens to the used car market in developing countries when a used Corolla bought in Mexico or Brazil costs roughly $15,000 and a brand new Chinese-made car costs roughly $10,000. He says nobody has played that out yet.
- Australia already has double-digit household solar penetration and severe duck curves in essentially every major grid area. The batteries are priced to move and sold as an add-on to solar that is already on the roof.
- On Chinese trucks, his explanation for the ramp rate is that the supporting infrastructure already exists, so China avoids the cold-start problem he says is slowing the US and parts of Europe.
- Kann gestures at the Trump administration’s Venezuela strategy as sitting oddly against a 5% oversupplied oil market, and explicitly declines to make the point directly.
- The underlying deck is public, roughly 200 slides at nathanielbullard.com, and both speakers refer to slides by number throughout.
06Claims worth citing
All figures as stated on 2026-01-22, drawn from Bullard’s deck unless noted. Prices, investment totals and deployment rates here are fast-moving quantities, and several are explicitly single-year snapshots.
- S&P Global Clean Energy Transition Index up 40% in calendar year 2025, against about 20% for both the S&P and the Nasdaq 100. Bullard
- US energy startup investment just over $8 billion in 2022, barely past $2 billion in 2025; about 7% of all US startup investment in 2022 and “probably about two and a half percent” in 2025. Carta data, cited by Bullard
- US residential solar system prices down 3%, at $3.35 a watt; commercial up 9%; utility-scale fixed and tracking up 9 to 10%. The $3.35 figure is Kann’s, with Bullard adding that it is about three times the cost in Australia or Germany. Kann and Bullard
- Oil oversupplied by about 5 million barrels per day at the start of the year, roughly 5% of demand of a hundred-and-a-bit million barrels per day. IEA estimate, cited by Bullard
- Australia installing about 40,000 residential storage systems per month from July through November 2025. The follow-on claim, that a year at that pace would cover about 5% of Australian households, is Kann’s own arithmetic offered as context rather than a measured figure. Bullard for the rate, Kann for the household share
- About 42% of global passenger vehicle manufacturing took place in China in the first three quarters of 2025. Kann restates this as 40% of the world’s vehicles being made “by Chinese companies in China,” which is a claim about ownership rather than location; Bullard gives the figure as manufacturing in China and does not correct the restatement. Bullard, restated by Kann
- Chinese electric medium and heavy duty truck sales: 3,000 in 2020, 81,500 in the first half of 2025. Bullard
- About a third of new medium duty vehicles in China are electric, about 10% of heavy trucking by sales, against electric car sales well north of 50% share. The one-third figure is Kann’s and gets an unelaborated “yeah” from Bullard; the 10% and 50% figures are Bullard’s. Kann and Bullard
- Transformer prices have not fallen and are still ticking slightly upward. Bullard
- Predictions made on air and left unresolved: US energy startup investment above $3 billion in 2026, versus a possible tripling from $2 billion but not a return to $8 billion. Bullard and Kann respectively
- A Virginia-focused energy economist, December 2024: the 2032 data center load forecast is probably off by a factor of two, direction unknown. The transcript garbles “load” as “mode” in both the setup and the quote. quoted by Bullard
- The head of Instagram, February 2025: the industry may need drastically more or drastically less capacity than it thought to build frontier models. quoted by Bullard
07Where it’s contested
- Nothing here is settled, by design. The episode is a survey of data points that ends on “nobody knows anything,” which Bullard immediately qualifies: there is a lot worth trying to learn and a lot of good information available.
- The startup investment bet is an open disagreement about magnitude, not direction. Both expect a recovery; Bullard says above $3 billion and Kann says possibly triple. They agree to revisit it in a year. Worth noting that Kann leads early-stage venture strategy at Energy Impact Partners, so the more bullish number comes from someone who invests in this category for a living.
- Bullard undercuts his own metric while defending it. If companies are about to pivot into energy applications and be counted as energy startups, the series he just quoted gets harder to compare across years. He frames the blurring as good for the sector rather than as a problem with the data, and the tension is left standing.
- Transformers: same facts, different reading. Bullard treats manufacturer caution as rational given uncertain demand. Kann says there is less excuse in transformers, which are less capital intensive and less concentrated, and predicts the problem gets solved. Neither claims it has been.
- The China vehicle statistic gets restated at a different scope. Kann’s ownership framing and Bullard’s manufacturing-location figure are not the same claim, and the guest lets the restatement pass without endorsing it.
