1) New paper! Replacing US fossil-fueled vehicles & appliances with electric versions could improve health & climate outcomes, but could cost up to $790 billion in distribution grid reinforcement. Strategic demand-side management could cut 2/3 of those costs.🔌💡

www.sciencedirect.com/science/arti...
"Science for society" blurb from the paper:

In a future with clean electricity and full electrification of buildings and private vehicles, the United States would emit about half the greenhouse gas pollution than it does today. However, buildings and vehicles would also use much more electricity, especially in the coldest weather. Here, we show that reinforcing distribution grids to accommodate these new peaks in electricity demand could cost Americans $2,800–$6,400 per household. We also show that “smart electrification”—accompanying electrification with measures that mitigate electricity demand peaks, such as reducing thermal demand, improving equipment efficiencies, and coordinating device operation—could reduce grid reinforcement costs by over two-thirds. We believe that achieving an affordable, all-electric future will require cooperation between engineers to develop enabling technologies, social scientists to guide technology development toward people’s wants and needs, and policymakers to pass laws or incentives that shape technology adoption.

"As has been happening for years, the U.S. could continue to lose gigawatts of power as hydroelectric facilities shut down rather than absorb the high costs of relicensing — especially with cheaper competition from gas, wind, and solar." From @alexckaufman.bsky.social via @canarymedia.com

EEI: utilities will spend $1.1T over the next 5 years, with 91 GW of new capacity under construction, another 488 GW planned or proposed. This is a massive expansion of the grid, currently at 1,250 GW capacity. Yet the trade group is silent on who covers this cost - and the climate implications.

BYD sales in the UK up *880%* year on year.

This is what happens when you embrace the open market (used to be a thing, remember?). The UK chose not to impose tariffs on EV imports, unlike the EU and the US. And guess who benefits? The customers. Shocking! Scandalous! 😁

The @iea.org's guess at the variable renewable energy share in various countries by 2030 - Denmark will be around 78%.

None of this was meant to be even remotely possible!!

The idea that people have been able to claim that Identifying public officials who are working for the state (which pays them with OUR tax dollars) is doxing is just 🤯!
hannahgais.bsky.social
Identifying public officials isn't "doxing." People have the right to know who is working for their government. Nor, for that matter, is it "radical left-wing terrorism." So it's frustrating to see platforms caving to these bad faith characterizations. www.technologyreview.com/2025/10/06/1...

There's a very nice new report from @climateanalytics.org on precisely this: "Hard to abate" has become its own form of subtle climate delay --->>

@billhare.bsky.social @cindybax.bsky.social

Conclusion
The persistent classification of iron and steel and cement as “hard-to-abate” sectors has
shaped both policy and industrial responses in ways that risk undermining the urgency
and effectiveness of global climate mitigation efforts.
While the technical and process-related challenges in these sectors are non-trivial, the
evidence presented in this report demonstrates that their decarbonisation is not only
possible but highly achievable with existing and emerging technologies—especially
when guided by integrated, whole-of-system approaches and supported by robust
policy frameworks.
A narrow focus on production-side constraints—such as process emissions in clinker
production or the fossil fuel dependence of BF-BOF steelmaking—has encouraged
decarbonization strategies put forward by the industry to rely heavily on CCUS and
offsetting as core mitigation strategies. This framing assumes that a substantial portion
of sectoral emissions are unavoidable, which justifies delayed action and continued
operation of high-emissions infrastructure. However, our analysis shows that much of
what is labelled “residual” or “unavoidable” emissions can, in fact, be abated at source
through a combination of clean technology deployment, material efficiency, and
demand-side reductions.
In the iron and steel sector, commercially available technologies—particularly electric arc
furnaces (EAFs) coupled with high scrap availability and direct reduced iron (DRI) using
green hydrogen—can replace the BF-BOF pathway. While steel production capacity is
long-lived and capital-intensive, studies show that aligning investment timelines with
early retrofit and decommissioning schedules could reduce cumulative emissions by up
to 66% over 2020–2050, compared to just 47% if low-carbon measures are delayed by
five years.

I recently wrote about how the US natural gas (methane) producers desperately need the world to get hooked on LNG imports. They need new markets for their gas. Why? From @ember-energy.org :

"global gas generation also fell (-6.3 TWh, -0.2%)"

The world is using less gas.

Seems significant.

"Imports of LNG from the US declined by 41 per cent last month from a year earlier and by 23 per cent month-on-month."

The headline explains what is driving this.

"Economics trumps politics: India's US oil, LNG imports slump sharply"

This is a privileged complaint, but one thing I find really, really insidious about search-embedded LLMs that affects my life is that summaries make me sound way less technical than I am, and also basically claim that I advocate for really problematic technologies as social justice tools.

I'm genuinely starting to think that the people who say they want to see American's really fight back are really saying they want a specific kind of visible, stereotypical depiction of protest, and have zero zero tolerance for the kind of groundwork it takes to make change happen.
