Good news on congestion pricing.

Now let's tackle street parking.

There are at least 3 illegally parked cars in this picture illustrating the @nytimes.com congestion pricing story.

Every once in a while, someone discovers that nuclear is low-carbon and tries to stick it to renewables as a result.

Yes, the German nuclear phaseout was a mistake. Of course.

Meanwhile, Électricité de France has been fully nationalized to keep its reactors running. A model for the US?

The Venezuela morass told through @wsj.com's Energy & Oil newsletter is...something.

The moral depravity of the Trump admin alone is nuts. The go-it-alone incompetence is another matter altogether.

"My own morality. My own mind. It's the only thing that can stop me."

Hard to think of a scarier, or more consequential, pullout quote on the @nytimes.com front page.

Not quite as mesmerizing as Utrecht bike commuters in 5cm of snow, but still rather grand 😎

I'm sure that's the case. I didn't delete it either. At the time, I deleted all but one tweet — saying I was no longer there.

xcancel tells me it no longer exists, so they must have deleted it at some point.

Couldn't agree more. Lists FTW

When did we start calling fusion a "renewable energy source"?

Not entirely wrong on the substance, but then again, we also don't call fast breeder fission reactors "renewable," do we?

The @wsj.com sending these alerts out via their "energy & oil" news alerts is a choice

Nobody ever said the death throes of the fossil age would be pretty or peaceful

Always striking to me how "range anxiety" is still part of our EV discourse, while images like these are standard fare for every catastrophe.

Yes, you can count to 1,023 with 10 fingers

In case you're wondering what makes a great, sustainable business: the namesake owner shows up to open the store on a holiday to give one of his employees the day off, spends the morning cleaning.

Stubnerkogel = vacation 🚡⛷️

Also basically why I do what I do: work to limit climate change and help preserve this.
