As the EU continues to rely even more heavily on importing US LNG and is kicking the can on methane regulations to make this happen, perhaps they should ponder the risks of handing this sort of energy dependence to a country that elected Trump. Because it gives him leverage...like with diesel.

Back on my Ethanol soapbox - Even under some generous assumptions, electrifying just 3.6% of the current gasoline-powered fleet would free up enough land to power EVs replacing the entire gasoline fleet with solar.

In the year I've been working w/ air pollution regulators on data center on-site emissions, I've seen almost no acknowledgement of this trend from energy-side advocates of data center buildout. This isn't just bad actors-it's a corporate playbook and a roadmap to a future of unconstrained emissions.

The Senate draft includes $255M per year (plus $200M for historic preservation). If spent on nothing but staff, that could pay 2,550 people $100k per year, but some portion of it would be spent on stuff other than staff. The draft does mandate building AI tools to generate and review env't docs.

Excellent, sensible, and welcome thoughts from @rephuffman.bsky.social, ranking member of the House Committee on Natural Resources, on the Senate permitting deal.
My thoughts on the Senate's permitting reform bill: 
 
Passing a good permitting reform package will be one of my top priorities for the next Congress, so I'm very interested in these Senate negotiations. 
 
From what I've seen, Senators Whitehouse and Heinrich have done some good work, but they've been negotiating from a position of weakness and the tentative deal unveiled today raises significant questions and concerns that would have to be resolved before most Democrats could support it. 
 
I'm all for streamlining transmission and clean energy buildout, but the threshold requirement before making major policy concessions is to actually end Trump's war on renewables so that hundreds of bottled-up clean energy projects can bring that affordable power to the grid. Further, we can't throw states, tribes, impacted communities, and threatened and endangered wildlife under the bus. And as we streamline and cut red tape, we must make sure the American people — not just powerful corporate interests — have a say in government decisions about what happens to our air, water, and public lands. That's what serious, responsible permitting reform looks like.There's a way to get there, and parts of this deal are helpful, but some of it concedes too much. Hollowing out the Endangered Species Act through the delegation of authority and problematic definitions, for example, is so extreme that a milder version of it spooked several House Republicans off of Bruce Westerman's ESA bill earlier this year, so you can imagine how it's going to land with the American people who overwhelmingly support protecting wildlife. And the provisions that seek to guarantee fair treatment for wind, solar, and battery storage are novel, untested, and don't really end the war on clean energy, but they will still trigger cries of "Green New Deal" and fierce opposition from the House Freedom Caucus, clouding any path to pass this deal through the House unless it gets much worse. And knowing the GOP players, that's exactly what will happen if this bill advances in the lame duck. 
 
The bottom line for me, and I believe most Democrats, is that November 3rd is coming and we are likely to soon have a far better negotiating position. Folding our hand now or in the lame duck makes no sense when we can keep working on this and, in a few more months, have a much better deal that works for everyone.

Can anyone explain to me why a national permitting deal is best negotiated now, mere weeks from an election that is likely to reshape federal power? Let’s stipulate that a deal of some kind is necessary and good; my question is what about the situation makes now more desirable than, say, Q1 2027?

This is a meaningful accelerant for building electrification and a good reclamation of "choice" from the gas utilities that have long tried to make an exclusive claim to that term.

Kevin J. Kircher @kevinjkircher.com · 01/10/2026
...just slow down their replacement timelines a lot so they can keep households on gas and avoid having to cough up $ to help them electrify (and thereby exit the gas system). As ever, getting good behavior out of monopoly utilities requires a big, skilled, skeptical, well-funded regulatory staff.

Kevin J. Kircher @kevinjkircher.com · 01/10/2026
Leaving this up to gas utilities to implement is recipe for failure. Gas utilities replace things on fast schedules today because every $ they spend on pipes is a $ they can rate-base and earn shareholder profits on. If forced to give $ to households for electrification instead, I imagine they'll...

Kevin J. Kircher @kevinjkircher.com · 01/10/2026
This is great! Replacing gas service (smallish pipe connecting building to big pipe under street) can cost $10k or more, a sizable chunk of the cost of just upgrading gas appliances to electric versions. Using that $ for electrification is a good idea, though we'll see how implementation goes.

A bill this big and complex will inevitably have unforeseen consequences. If those consequences are bad for fossil fuel companies, their owners/execs/major shareholders have a good chance of changing the bill scope or implementation by working lawsuits up to the Supreme Court. But Dems? No chance.

One thing to bear in mind about a federal permitting bill is that its mistakes would be essentially permanent - Dems could only reverse mistakes with a filibuster-proof 60-vote supermajority in the Senate. Repubs, on the other hand, could use captured courts to shave off bits their donors dislike.

As far as I can tell, the total funding in the Senate permitting bill is $255M/yr (0.0036% of 2025 $7T federal spending), not counting $200M/yr for historic preservation. $255M is enough to pay 2,550 people $100k. You'd think a bill meant to expedite permitting would hire/pay people to do the work.

Not a lawyer, but "SEC. 209. ENEPA TECHNOLOGIES" (pages 74-94) appears to require creation of AI tools for a) company use to generate environmental docs and b) agency use to review environmental docs. AI-generated forms reviewed by AI tools in understaffed/underfunded agencies! What could go wrong.
