    Our readingSolar power combined with batteries has surpassed nuclear power as the superior energy technology for most uses.

    Their wordsBecause solar has, broadly speaking, won the technological race. Intermittency was the last big problem, and batteries have gotten good and cheap enough to make solar reliable.

    Our readingAbout a fifth of the US grid could be freed for data centres just by covering the yearly peak with batteries or peaker plants.

    Their wordsThen all of a sudden, you've unlocked 20% of the US grid for data centers because most of the times that capacity is sitting idle and it's really only there for that peak, right? Which is a day or two, right?

    Their wordsThe rapid drop in renewable energy costs in the last decade (alongside huge improvements in battery technologies) has started to break this deadlock.

    Our readingNobody will finance new gas turbine factories, because paying one off takes twenty years of a market that solar and batteries will already have taken.

    Their wordsYou you also don't know like in order to make that money back, you have to then operate that plant at that capacity for 20 years, right? And if I was looking at the same charts as they're looking at right now, I'd say what are the odds that in 25 years time we can produce gas turbines at a price that is relevant in a world where solar is already at its current price and batteries at a price where they're already like you cannot win.

    Our readingFusion and solar are the two energy sources worth betting on, and solar's limiting problem is batteries and transmission.

    Their wordsI think fusion and solar are the two that I would bet on. Solar, I mean it's the fusion reactor in the sky of course, and I think really the problem there is batteries and transmission.

    Our readingChinese solar panels and batteries are cheap because of automation and a honed supply chain, not because of cheap labour.

    Their wordsBut, China mainly dominates these markets because it has produced a long-term industrial strategy for these technologies and has honed an optimised, modern supply chain as a result.

    Our readingBelow about a thousand dollars a kilowatt of capital cost, the right way to run a plant is intermittently on raw solar with no batteries at all.

    Their wordsFor loads below $1000/kW, intermittent operation with some modest solar array oversizing is the winning strategy. Above $1000/kW, we charge and discharge batteries daily to run them.

    Our readingPast a point it is cheaper to overbuild solar than to add batteries, because a battery kept for the rare bad day is barely used.

    Their wordsA battery that’s discharging every day gets great utilization, but one that’s only there in case the sun doesn’t come up for two days in a row, barely gets used.

    Our readingChina's industrial lead was manufactured by deliberate state industrial policy rather than by market forces alone.

    Their wordsThe foundations of China’s success in EVs were built a decade ago, when the state decided to bet on batteries, and then bought up a lot of the mines for these metals.

    Our readingThe end state of the grid is not a fifth solar backed by spinning generation, but twice the demand in solar with days of storage behind it.

    Their wordsThe logical end state of this displacement is not some hybrid grid with around 20% solar backed up by spinning generation, but a much more dynamic, versatile grid with around 200% solar generation and hours to days or weeks of battery storage, fully decoupling time of generation and consumption.

    Our readingBatteries will replace transmission as the cheapest way to keep the lights on, and the grid will shrink rather than grow.

    Their wordswe will see batteries aggressively displace transmission as the most cost-effective way to ensure continuity of electricity supply, leading to an eventual pruning of the grid and drastic reduction in the average distance that power travels between production and consumption, even as the average time that power is stored increases.

    Our readingThe multicopter air taxi is energy-intensive by construction, which holds its range to about twenty miles however good the batteries get.

    Their wordsThe drone-like architecture of the multicopters is simple, but as the rotors are responsible for keeping the unit at a constant altitude with hover power, they represent an energy-intensive version of VTOLs. Their range is, therefore, short, typically less than 20 miles.
