1) We have entered the Climate Epoch

The IPCC AR6 2021 is the starting 🔫. The next period in human history will be defined by the changing climate, and how society and governments react.

Nvidia just figured out how to put an AI data center on the side of your house. And pay you to host it.

Each XFRA node packs 16 Blackwell RTX Pro 6000 GPUs, 4 AMD EPYC CPUs, and 3TB of RAM in a Dell PowerEdge rack mounted next to the AC condenser. The homeowner pays nothing for the hardware. They get discounted electricity and internet in exchange for letting Span tap unused capacity on their electrical panel.

This sounds insane until you look at the actual constraint blocking AI infrastructure.

Hyperscalers are not GPU-limited. Nvidia ships them on schedule. They are not capital-limited. They are sitting on hundreds of billions in capex. What they cannot get is grid interconnection. A 100MW data center requires a substation upgrade that takes 4 to 7 years in most US markets. US grid operators have over 2,600 gigawatts stuck in their interconnection queues per Lawrence Berkeley Lab. The wait, not the silicon, is the bottleneck.

Span solved this by going behind the meter.

A new Pulte home has 200A service. That's 48kW of capacity. The home uses 1 to 3kW most hours. The headroom never gets touched. Span's smart panel measures real-time consumption and dynamically routes whatever the home isn't using to the XFRA node. No substation upgrade. No queue. Just slack capacity sitting on the residential side of the meter, already cleared.

Span claims it can deploy 8,000 nodes for one fifth the cost of a comparable 100MW centralized facility, six times faster.

PulteGroup is the wedge. They delivered 29,000 homes in 2025. The XFRA unit goes in during construction next to the smart meter. No retrofit. Pulte gets a feature on the spec sheet and revenue share on the compute that flows through the wall.

The grid was the bottleneck. Pulte just became the workaround.

1/Closing the year out at Fervo with one more big announcement: a new funding round. Fervo has raised a $462 million Series E led by B Capital to accelerate our geothermal pipeline.

@KatieS @MoxxieVentures How’d I miss this?! Such a lovely way to “work”!

@simrangsuri 😯 that's a big waitlist!

[Abe Yokell @CleanVC]

@QuincyEdmundLee @duncancampbell Don’t know for certain but suspect it’s a SOC technique - when intercalation occurs during charging the traditional measuring techniques can lose accuracy. There are some alternative approaches that can use a brief pause to calibrate. Track down @QnovoCorp if you’re bored!

Span has raised $96M to expand markets for its smart electrical panels. One big target market is home electrification - and Span's partnership with appliance maker Kenmore illustrates how its tech can play beyond rooftop solar, batteries and EV charging: https://t.co/06Nbo4ySmA

@SophiePurdom @posamentier @congruentvc Means a lot from you! Thanks for all you do!

[Abe Yokell @CleanVC]

@AnkeHuiskes @congruentvc @CanaryMediaInc @posamentier Have to keep feeding our portfolio founders! 😂

[Abe Yokell @CleanVC]

Fun to announce the fruits of @congruentvc' efforts! We're still getting started 6.5 years in but delighted to chat about our $300M fund to back our scaling companies! Nice to get the WSJ/Bloomberg/Axios/TC/Pitchbook pickup, but @CanaryMediaInc always slays.

.@congruentvc, one of the first venture capital firms to focus squarely on early-stage climate-oriented startups, just bucked broader market trends and roughly doubled its assets under management. https://t.co/TJ9xE09QtT

[Joshua Posamentier @posamentier]

So @CleanVC and I started @congruentvc 6.5yrs ago to focus on the earliest stage climate tech. Along the way, we invested in 51 (>25% women led/founded) startups across an amazing range of tech each driven by daring founders. It’s time to build. LFG.

Since there have been NO distractions the last few days... I'm sure you all want to come and listen to some live radio covering climate in the Bay Area.

[State of the Bay @stateofbay]

Join us @KALW 91.7FM at 6PM TONITE for our first CLIMATE SPECIAL

Sometimes good outcomes take patience... congrats to the @GaNSystems team and the good Dr. @DanielHullah on the $830M sale to Infineon!

Daniel co-led the seed round back in 2011 while at RockPort... 12 years later, here we are!
