Supreme Court overturns FERC solar approval after Chevron’s demisewww.eenews.net The case is considered an important precedent for renewable energy under the Public Utility Regulatory Policies Act (PURPA).

GM will pay nearly $150 million and retire $100s of millions of emissions credits to settle with the EPA for selling nearly six million cars that emitted more carbon dioxide than the company had claimed, violating federal regulations. www.nytimes.com/2024/07/03/c...

Here’s how the Supreme Court's decision to end the "Chevron doctrine" and expand judicial review of administrative agency decisions could affect climate regulation: www.nytimes.com/2024/07/02/c...

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."

A $2-3 billion battery factory for electric trucks just broke ground in Mississippi. The joint venture of Daimler Trucks, Accelera by Cummins, and truck maker PACCAR will build 21 GWh/year of LFP battery cells & bring 2,000 jobs to the local community electrek.co/2024/07/02/b... 🔌💡 🔌🚗

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 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.

The American automotive consumer is hard to satisfy! @heatmap.news I make the case that EVs with gas tanks—"range-extended electric vehicles" or "series plug-in hybrids"—might be key to electrifying some of the toughest market segments in the near-term. heatmap.news/electric-veh... 🔌🚗 🔌💡

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. static.nhtsa.gov/odi/rcl/2024...

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.
