if you were devising an ultimate clean energy / climate tech / decarbonization must read book list, what would you put on it?

And @Poshmarkapp changed their layout to include ads every 5 listing and it really makes the whole let me haggle for $150 worth of second hand clothes I don’t need much less fun 🙄

One of my biggest pet peeves in marketing copy is calling expensive expenses “investments” to make people feel differently about them when they are clearly not that 😭 no shade if you are spending $8k+ on florals, but you’re not investing in anything

I’m keeping track of weird AI phrases that show up in copy: “what stays with me the most”

Another massive battery storage record in California (CAISO) yesterday, March 29 🔋

At 7pm, batteries reached 12.3 GW of output, meeting 42.8% of demand!

And it's not just a short peak anymore. Batteries stayed above 20% of grid supply from 5.50pm to 9.35pm, almost four hours.

I’ve been saying for the past five years that social media will be the tobacco industry of my generation, but high key much worse. These court decisions are just the beginning.

People misunderstand how much China’s switch to electrification is in fact a Churchill-ian approach to switching from a steam to an oil navy…

Having a lot of conversations this weekend about the Oracle/Abilene expansion. Here’s the latest:

• Oracle’s exclusivity period on the Abilene expansion expired last week.

• BUT Oracle was planning to rent GPUs in Abilene to another major customer—NOT OpenAI.

(OpenAI decided several weeks ago not to expand beyond 1.2GW Abilene. See post below.)

• Nvidia has put down a $150 M deposit and is in exclusivity to be the tenant. Nvidia is in talks with multiple potential customers to rent the compute, including Meta.

• The expansion was designed specifically for next-gen Nvidia chips, so Nvidia had an interest in keeping the project moving.

I would like someone to unpack chat gpt’s strong tendency to use “quietly” as a choice adverb, for things not involving sound 🙄 no one writes this way!! No one wants to write overusing the metaphorical use of quietly! It is so bizarre. This is just one example,

Insightful article: Google's new AI infrastructure chief Amin Vahdat says $185B in capex this year is just the start. At that run rate for 10 years, spending could reach $1.9T over a decade. TPU demand is "unprecedented" with Morgan Stanley estimating $13B in TPU revenue for GOOGL by 2027. Google now shifting to modular data center designs to scale globally.

@JackLondonOak is this something you can help with or at least help us to get in touch with the right folks @ the City to get this nuisance resolved?

[Marisa Sweeney @sweenenergy]

We need @shell to address the 24/7 trespassing deterrent that blares from its shuttered station, audible from 300+ homes in our area in JLS Oakland. It is a total public nuisance and I’m sure harming business for our locally owned mezcaleria across the street. SO unacceptable!

[Marisa Sweeney @sweenenergy]

@charlenewang is this something your office can help with? Our neighbors have been making 311 reports and calls, daily! The site operator used to have a security guard, but now they’ve resorted to this extreme measure that is audible across our entire 200+ unit complex a block away
