Is decarbonization dead? @janeaflegal.bsky.social & I join Ezra Klein to talk through how Trump just shredded America's most ambitious climate policy, what survived, and where we go from here. Listen @nytimes.com or wherever you get your podcasts.

Favorite reads: the ERL paper, plus new work showing EV adoption induces clean capacity builds (www.pnas.org/doi/10.1073/...), and that V2G can even push net emissions negative in some cases (pubs.acs.org/doi/full/10....). 9/

Flexible charging (and V2G) matters: uncontrolled evening charging can lean on gas/coal; controlled/V2G boosts the business case for new wind/solar/storage, so total system emissions can fall even as EV load rises. 6/

It even finds that using short-run marginal emissions as a control signal can backfire, worse than price-based signals, because it ignores how charging affects investment: iopscience.iop.org/article/10.1... 5/

The excellent new ERL paper by Bhandarkar, Luo, Dimanchev, & Jenkins shows that when you let the grid build (wind/solar/storage/gas) in response to EVs, simple averages or short-run marginals can mislead, often understating EV climate benefits. 4/

Modeling Monday: How clean are EVs, really?
Short answer: it depends on the question. Attributional vs. consequential LCA, average vs. marginal, short- vs. long-run... the metric can flip the answer. 1/🧵

Given that many feel the Biden Admin did the same thing to oil/gas pipelines during his term, perhaps this opens up further motivation for a new, more sensible energy permitting regime. Perhaps...

Any permitting reform package should contain measures that limit if not outright prevent the executive's arbitrary and politicized application of routine permitting processes to block disfavored technologies.

America’s biggest offshore wind farm will be online in six months.
"Dominion Energy’s 2.6 GW project off Virginia’s coast is progressing fast. The utility has a new, more definitive target to plug into the grid: March 2026." Via @canarymedia.com

Construction begins this week on a new, upgraded AirTrain at Newark Liberty Airport. The 2.5 mile system is "expected" to cost $3.5 billion and complete in... 2030! 🤦‍♂️https://www.yahoo.com/news/articles/outdated-newark-airport-build-3-214920061.html

5 years for 2.5 miles. Just amazing work America.😕

Some DIY people have hacked their chargers but haven't seen any practical solutions for my program. I recently moved so now have to go through expense of installing whole new charger and 220V circuit again...

The government’s own data rebuts Trump Admin claims that wind and solar are driving up electricity prices, Politico reports share.google/RTIXPPQMXrTH...
“[T]he data say pretty much the opposite” of Trump & Secretary Wright’s claims.
Among the 22 states that drew higher-than-average shares of their power from wind and solar, 17 had below-average electricity prices in June, according to EIA data.

Solar leads EU electricity generation as renewables hit 54% share.google/WEiX2aSdEwj9... 🔌💡 ☀️
According to new data from Eurostat, renewable energy sources generated 54% of the EU’s net electricity in Q2 2025, up from 52.7% year-over-year. The growth came mainly from solar, which produced 122,317 gigawatt-hours (GWh) – nearly 20% of the total electricity generation mix.

June 2025 was a milestone month: Solar became the EU’s single largest electricity source for the first time ever. It supplied 22% of all power that month, edging out nuclear (21.6%), wind (15.8%), hydro (14.1%), and natural gas (13.8%).
