High new car prices aren't a new problem -- it's a result of explicit automaker strategy: "Automakers aren’t sufficiently motivated to solve the affordability crisis because they’re making more money selling fewer cars to richer buyers." This is from 2016: thehill.com/blogs/congress…
STICKER SHOCK: Soaring housing & grocery costs get most of the attention. But new car prices now average $48K, creating an auto affordability crisis that is laying waste to a fundamental aspiration of American life: a new model in the driveway. @JeffAGreen bloomberg.com/news/articles/…
The shift from fossil fuel imports to clean technology imports can improve the resilience of energy supply A large container ship of solar panels can provide the means to produce as much electricity as the gas from over 50 large LNG tankers or the coal from over 100 large ships
Telling about Musk's underlying motivations that the only concrete spending cut he mentions in this clip is firing IRS personnel, which would not make any meaningful reduction in the deficit but would make it easier for e.g. wealthy people to avoid taxes
Elon Musk Says We Have to Cut Government Spending Immediately "The reality is that all government spending is actually taxation. Sometimes people think some of it is taxation and some of it's not, but it's all taxation, because the part that is not covered by tax revenue becomes…
49%! of EVs in Q2 2024 were leased (up from 21% in 2021), benefitting from full $7500 subsidy via IRA's 45W without income/MSRP/domestic content/mfg requirements. P.S. leasing company also in line to benefit from 25E Used Clean Vehicle Credit of $4000 if lease terminated
IRS clarifies that leased PHEV-7kWh, BEVs, FCEVs will be eligible for $7500 to the lessor (dealer) via IRS 45W Commercial Clean Vehicle Credit unlike IRS 30D's $7500 (New Clean Veh Credit) subject to US assembly, battery, crit mineral, income cap, MSRP cap cars.com/articles/lease…
It took me SEVEN years to figure out that you can save a ggplot as a vectorized .svg file ggsave("file.svg"). The svg file can be opened on powerpoint and it will be completely vectorized, even text are still recognized as text boxes! No more recreating plots on illustrator!!!!!
Anything like it in North America? @WorldBollard
A few more tests and then they’re ready to save the world. #WorldBollardAssociation 🎥@KirstendeVos twitter.com/KirstendeVos/s…

The single greatest amplifier of fake videos and the people who create them on the internet in the world today is the owner of this platform. Example after example after example
This variability is kinda insane, no wonder Midwest people scoff at forecasts.
Fascinating how the American perception of "Europeans" is the same as the European perception of "Italians" is the same as the Italian perception of "Southern Italians" and so on, like in a fractal or something
Your european colleagues when you try following up with them on a critical project due two weeks ago
I mean, read the GOP party platform! Read Project 2025! They propose radical changes to the status quo, radical movement backward. They are, in that way, deeply, deeply weird. That's what everyone is finally starting to pick up on & Walz has finally made explicit.
The only thing car drivers care about is the paint of their cars so bollards are the best way to limit speed in cities.
The Supreme Court just blew up four decades of precedent today, in a decision that will make it harder for executive agencies to protect the environment, public health, worker safety and more. axios.com/2024/06/28/sup… This will create utter chaos in the courts, as no one knows…
Last week, I read about one of the bleakest uses for gen AI I've seen yet: First Horizon Bank is rolling out a system to detect when a call center worker was on the brink of "losing it"—and play them an AI-made montage of family photos set to their favorite song to calm them down
At @EIAgov, we’ve just released our National Energy Modeling System (NEMS) – used to produce the Annual Energy Outlook – as an open source product, with additional EIA code to follow. github.com/EIAgov/NEMS
Anyone who works in the US automotive industry, EV industry, or in policymaking should taken ten minutes and read @GaytonaUSA's new piece for @InsideEVs on Chinese EVs. It's a barn burner. And arguably a warning about the cost of inaction. insideevs.com/features/71901…
There's been a lot of consternation & digital ink spilled over Bitcoin, data centers, AI and their impact on the grid. But do you know what's even bigger load growth driver, according to @TheBrattleGroup: hydrogen electrolysis! Wouldn't it be good if @USTreasury ensured 10s of…
In a new report, Brattle energy experts examine the rapidly changing landscape of load drivers and how they complicate #loadforecasting for utilities and system operators, introducing significant risks associated with under-forecasting. bit.ly/3UQgcXo #EnergyTwitter
Two things happened on the @California_ISO grid last night. 1) Battery storage discharge went over 6GW for the first time AND 2) Batteries were the largest source of supply.
Yeah, but it got the colors wrong and also, you don’t need different colors on this chart.
ChatGPT can now create graphs in seconds. Stop wasting hours on Excel and watching tutorials. Here's how to create any charts or graphs with ChatGPT:
Exciting news, our Speaker Series is back! We're kicking it off with "Communicating Uncertainty in Macro-Energy Systems to Decision Makers". Our excellent panelists are Leslie Abrahams from @cleanaircatf, Joseph DeCarolis @EIA_One, and @srujana_goteti, with @JXJohnson moderating
