The effect will also be differentiated. Before it was oil producers v the rest. Now, places with high renewable energy use and high EV penetration will be much less affected. Others will need to catch up.

The Renaissance (1485 to 1603) As England’s population rebounded after the Black Death, so too did its coal market. At the beginning Β of the Renaissance, most coalfields were still controlled by the church. Without medieval feud…

UK used large amounts of coal long before the Industrial Revolution:

...so it's a big and unnecessary disadvantage to stop it, but maybe we can at least make some progress on solar during Trump.

Would be nice if they had some support for individual rooftop and community solar as well. Bring back the Green Tea Party.

Solar is a sufficiently big business to be financially attractive to MAGA proponents. Again, I'll take it.

TBF, before the Inauguration some MAGA types said their energy policy was "everything but wind" (because Trump hates wind). This might be reverting to that idea.

Wind is quite valuable....

Briefly skimmed this - I didn't see any discussion of whether AVs reduce private vehicle parking needs and therefore increase urban density. Seems like it only looked at negative effects. Not sure what to think, but again all I did was skim.

Rising carbon dioxide levels now detected in human blood Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue. ...

One more thing to worry about - rising CO2 affecting our blood pH levels.

I assume this is also affected by indoor CO2 which is easier to fix, but still emblematic of the problem (and one fix is to get rid of methane gas for heating, water, and cooking).

It's ridiculous. Complex legislation almost never should be done by voter initiative. Voter initiatives should be used to overcome powerful groups that use their money to stop legislative bills.

This is a powerful group instead using money to pull a fast one on the people.

European EV sales are similar to California's.

power outage vulnerability map for the U.S.

power outage vulnerability map for the U.S.

A nice map from a 2024 paper showing which counties have the highest vulnerability to their power grid, based on power outage data from 2014-2023. It rated the counties holding Los Angeles/Riverside/San Bernardino, Houston, Miami, Fort Lauderdale, and Detroit as ones facing "extreme" risk.

I've wondered whether they'll use the fact that they're being sued to argue that the endangerment finding still exists and therefore the legal field is occupied, while also trying to get rid of the finding.

Might be harder though for the states being sued to say the feds must keep endangerment.

25.02.2026 21:09 πŸ‘ 1 πŸ” 0 πŸ’¬ 0 πŸ“Œ 0

Their case is actually made weaker by the Trump Administration's abandonment of climate regulation. Kind of hard to argue the legal field has been fully occupied by the feds when the "occupier" has deserted.

Not Menlo Spark's typical thing, but too cool to pass up. Whale song from 1949.

And whales may play an important role in carbon sequestration....

Assemblymember Berman Introduces Legislation to Electrify California Homes The Home Energy Choice Act gives Californians the option to electrify their homes with money that would otherwise be spent on old gas service lines

I've seen a lot of discussion about what to do with EV batteries that have degraded to the point where they're no longer good for driving (recycle v. utility storage), but I haven't seen any discussion of what to do with an EV battery that's still useful and has outlived its car.You're not just going to stick it into a typical new EV. I suppose some could replace degraded batteries in used EVs, but I'm not sure how big that market will be in the long run. They could just sell at a slight premium for utility storage, but I'm not sure that's the highest use.Maybe we need a new market segment of new, cheap EVs made with used/reconditioned batteries.

EV batteries are lasting longer that EVs themselves. In my mind this raises a new "good problem" of what to do with these batteries that aren't new but still good enough to run EVs.

Why did Zillow remove climate data from its home listings? The home search site is pointing users elsewhere for climate risk info, a move it says aligns with β€œvarying” MLS rules. But what those rules are is not clear.

Great to see this, given that Zillow removed similar info under pressure from Realtors Associations, which are attempting to conceal future climate risks from the clients that individual Realtors represent.

Today we’re launching Open Climate Risk, a fully open option for U.S. building-level climate risk data. It’s unique because it allows you to see not only risk scores, starting with wildfire, but also the complete underlying dataset, methods, and codebase. carbonplan.org/research/cli...

Not as anti-CCS as Mark, but there are serious concerns, especially with other emissions not captured. Blue hydrogen has lots of problems.

Seems like it was generally a good idea.

No escalator in your solar lease payments though? Mine has one, although lower than utility price increases.

Each regional total also seems off. Maybe I'm missing something.

Nice visualization that it's not power generation that's a problem.

This graph seems strange though, the regional totals (white circles) don't look to me like they add up to the national total:

U.S. wholesale day-ahead electricity prices rose in 2025 with higher natural gas prices - U.S. Energy Information Administration (EIA)

Dark red line along the bottom of graph is CA, the place some misinformed folks say has expensive elec due to all its wind, solar, and batteries. (Counting RA cost doesn't chg the story) Our high rates pay for response to what climate change is already doing: wildfires.

DOE scientists blasted climate report ordered up by boss Secretary Chris Wright handpicked five climate contrarians to write about global warming. Department experts pushed back on the findings.

Internal emails show Department of Energy's debunked climate science report was reviewed by scientists internally, who found it "biased," "misleading," and "hypocritical." Contrarian authors tailored their work to ensure it focused on weakening climate regulations. www.eenews.net/articles/doe...

I was wondering about that as well. Hard to measure though. It's also post NEM2.0, but good if PV installation is still happening at that strong a pace.

Interesting the electricity demand in CA actually declined 2% last year. Might be cost-related.

I also heard a PG&E person say last year that they had lots of capacity available, so datacenters reduce their costs instead of increasing them. Not sure how to evaluate that.
