58. Traded electricity wholesale markets are the worst way of deciding how to dispatch energy resources, except for all the others that have been tried.

Cornhole concerns at the zoning committee: "The cornhole game leads to a continuous thunking noise as the beanbag hits the target. When one goes in the hole there's a loud cry of success."

Hey @didtherockieslose.bsky.social It’s the 7th inning and the Rockies have more runs than hits! And they have one run.
Is that good?

Sooooo. Are we building transmission in the USofA? Perhaps the most important infrastructure needed for cheap and clean energy?
No. No we are not.

Imagine if the Rockies could have had a guy like Elehuris Montero. Just imagine.
Trevor Bauer returned from the Japanese minor leagues today, and he immediately surrendered the longest home run in recorded history (594 ft) to Hiroshima’s Elehuris Montero

It’s both sad and fascinating to listen to NPR coverage right now.
Just constantly thinking of @volts.wtf‘s Epistemological Crisis.
Even as they report on their own destruction, they struggle to speak clearly.

Wait Joe, really?
Are you saying we could:
1) Force coal to run and increase prices by $15B, with no benefits?
Or
2) End energy poverty for $10B?
And we might choose #1?!

My team is proud to release new data on coal economics!
With some calling for increased reliance on coal, RMI has re-run the 2024 coal dispatch data, assuming all coal is self-scheduled at 100% of capacity.
The results: $15 billion in increased costs!

I crutched to the Boulder #NoKings today. Felt like the whole town was there.
This is going to be a long fight. But proud of our town today.
Photo not great as I’m limited with mobility.

@sarahtaber.bsky.social Hi Sarah I remember you once did a memorable thread (back on Twitter RIP) about the economics and motivations of farmers to convert to solar vs sell to housing developers. Is that right? Could you repost that?

Welcome to Grid version of the “War on Cars” Central NJ.
It’s a crazy sticky challenge and it’s fascinating to see you grappling with it.

One tidbit that I picked out of my ongoing review of 'Abundance' by Ezra Klein. Is this a serious proposal?
Ezra cites research from Jesse Jenkins at Princeton U., which estimates that to produce enough carbon-free electricity, we would need to build solar or wind farms on an area equivalent to the total land of Connecticut, Illinois, Indiana, Kentucky, Massachusetts, Ohio, Rhode Island and Tennessee... 😳

OK - Motivated by this poast, I just read the Fifth Risk. It’s a tremendous work honoring all the unheralded amazing public servants. I’ve had the chance to work with a few government servants similar to those described and the book is on point. And incredibly moving.
I cried at the end.

Today, my 19yo thanked me for turning him on to Michael Lewis's book "The Fifth Risk." He then went on to mumble, "I hate to admit it, but your book recommendations are on point."

Nuggets lose. Fully on the coach. He was up at the start of the 4Q. Don’t rest his guys. Despite it being the plan. And they were gassed by the end. And we lose decisively

Sing it from the rooftops: congestion pricing in NYC is an unambiguous triumph. It is succeeding beyond its backers wildest aspirations & none of the second-order effects people worried about have come to pass.
It's a pure win. Celebrate it! Talk about it! For once, let's own the f'ing narrative.

Here Is Everything That Has Changed Since Congestion Pricing Started in New York
Fewer cars. Faster travel. Less honking. And some questions we still can’t answer.
