It hasn’t received as much attention, but a Supreme Court ruling last week basically break the process by which the federal government responds to public comments in *any* process — which means it will take *longer* to permit new clean energy or new infrastructure. heatmap.news/climate/supr...

"Although Americans rarely interact with these rules, they affect the water we drink, air we breathe, and the food and drugs that we ingest."

@robinsonmeyer.bsky.social on how the Supreme Court's rulings last week could "substantially weaken the EPA for decades to come."

Contrast Toyota to Ford & GM who have launched EV versions of some of their most popular models (F150, Mustang, Silverado, Blazer, Eclipse etc), even when the new EV doesn't look like the corresponding ICE. That seems to be the right way to sell EVs... But what do I know? 🤷‍♂️

Apropos of nothing: it is still insane to me that Toyota released an EV that looks exactly like the RAV4, the top selling mid-size SUV in America, and they decided NOT to name it the RAV4e (or RAV3e since it's a tad smaller), but rather, the utterly unpronounceable bZ4x. 🤯🤷‍♂️

This will create utter chaos in the courts, as no one knows what the rules are now. There are more than 100 federal court decisions based on the 1984 Chevron v NRDC precedent SCOTUS just overturned. It's the most cited case in the whole field of administrative law.

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.

This is the world’s largest wind turbine: Goldwind’s GWH252-16MW intelligent wind turbine has a rotor diameter of 252m. It also has a swept area of around 50,000 sq – equivalent of seven standard football pitches. The turbine’s hub is 146m high – that’s as tall as a 50-story building.

You people aren't engineering geniuses and so might have silly thoughts in your brain like, "a four-foot windshield wiper will encounter a lot of friction, made worse by leverage."

On an unrelated note, every Cybertruck is recalled cuz the wiper ain't made right.

Fun facts (via IEA): the world produced 95 million metric tonnes of hydrogen in 2022. Over 3/4 is used in refining & fertilizer production. Conventional hydrogen production from natural gas reforming or coal gasification produced 0.9 gigatonnes CO2/yr, 2.5% of global CO2 emissions.

This is an important capital infusion for Rivian that helps them cross the Valley of Death to reach scale and positive gross margins. Will we even see further collab on a shared platform for VW's new "rugged" Scout brand of electric SUVs coming soon?

Not gonna lie: I've got a dinner event in the city this week, and I'm probably gonna drive! (My EV, but still...). Not going to count on NJ Transit when it's over 90° and I've got to get there on time. That sucks.

These observations on Chinese dominance of EV, battery supply chains, and critical minerals are in accord with my own work on the delicate balance between fostering domestic production/national security and sustaining the clean energy transition.

It's a bit complex (the various pollution/climate disaster mechanics are a lot to keep track of each turn!) but it captured the concept of local pollution vs externalities (negative spillovers of your fossil fueled development that impact everyone) quite well.

From growing up in a desert: If you have stuff to do, you’re done by 10 am, and you’ll pick it back up after sunset. Daytime is for being quiet and using little energy. This includes cooking. You don’t need hot food. Boil eggs, have hummus and cold cuts, cubed cheese, fruit and snack vegetables. 1/
