If we speak of political realities as if they are immovable *they will remain immovable* and I think it's high time that we start speaking of possibilities more than impediments.

As a reminder why this all matters--the 2020s is when storage was supposed to scale up to provide RA otherwsie providedby thermal gen. In CAISO, ERCOT, ISONE interconnection queues, storage topping all other resources, with WECC close to the same. #EnergySky

I think it's more than that. They want all regulatory agencies, plus any agency that provides benefits to ordinary people, to fail. That way, there will (in their minds) be less pushback when they eliminate them completely. Total elimination is the goal.

🧵The goal of withdrawing govt. agencies from being able to provide critical services that benefit people is distinctly different from the goal having these agencies be more efficient in how they operate. It's maddening how the former is being marketed as the latter. 1/

Hi, US coal has largely declined because the plants have well outlived their design life. Not because of climate policy, largely not because of other policy either. It’s old tech and the plants cost a lot to keep running.

People might think that whatever destruction is done to science in the US, we can undo in 4 years with a Democratic president and Congress. The problem is that many areas require specialized knowledge and skills built up over years, and once that's lost, it's hard to get back.

Our dams provide multiple critical functions & need expertise that can deal with that complexity - which will be even more important as climate variability increases. Yet another example that the admin either doesn't understand what they're cutting or likely that they do & they don't care.

Trump and Musk are basically trying to deskill America: 1) kill all white-collar jobs and replace them with AI 2) kill universities 3) use tariffs to turn the U.S. into an economic island manufacturing, oil and ag hub 4) empty the cities 5) push men into manual labor & women back into the kitchen

All of this is true. I also think Americans who voted for the concept of "American greatness" are unprepared for the downstream impacts of dismantling most of the institutions of American prestige and soft power, while also burning alliances and geopolitical trust.

The irony is that between DOGE and Trumps tariffs they’re endangering the anchor of a lot of American prosperity, which is centuries of political stability and rule of law which makes a place people want to put capital. None of these dweebs grasp that.

Update: was able to bike to eat lunch. Slowly starting to increase the distance I can e-bike. Still a long way from recovering enough to ride my regular bike though! Also it looks weird when I roll up on my e-bike then get out my cane to walk. E-biking is easier on my foot than walking though!

Imagine DOGE opens your mail and finds your household electric bill. To eliminate this cost, they burn your house down without warning. Then they total up the bills that, as a homeless person, you will never again pay. On its website, DOGE boasts about the money it has saved you.

Weather forecasts aren't just for helping you figure out what clothes to wear. They're critically important for early warning against extreme events that can damage people & infrastructure and for helping communities prepare for them. Gutting NWS capability directly puts lives at risk.

I want to be clear: the private sector, as it presently exists, *cannot* quickly spin up to fill any void left by substantial dismantling of #NOAA. Full stop. If that were to happen, people would die in extreme weather events who would not have otherwise, & economy would suffer.

Maybe its the medication I've been given by my rheumatologist (+physical therapy), but I went from being unsure about riding a bike ever again to riding my pedal-assist e-bike for an errand in ~3 weeks. I still walk with a cane & getting on/off the bike is hard, but once I'm on it I can ride a bit.

if the president can say “i don’t like the department of energy,” and within a week it’s closed, then the constitution means nothing, and the president’s entire claim to power is the loyalty of the military. either he is constrained by the constitution or he’s a dictator, there isn’t a middle ground

Agency after agency is being ransacked by 20-something Muskovites at DOGE. Trump Admin threatens to lay off 1/4 to 1/2 of employees at the National Science Foundation. Cutting staff at the $10b/year grantmaking agency would “gut the intellectual center of U.S. leadership in science and technology."

Amidst the craziness, a small bit of joy here: I managed to ride my pedal-assist e-bike around the block. 🚲 With my 15-months and counting mobility issues, I wasn't sure I was ever going to be able to ride a bike again. Still a very long way to go, but rolling for even a couple minutes was euphoric

My only personal resolution for this year is the same as it was last year: get back to being able to walk normally. Didn't quite get there in 2024, but the last 2 months of the year did show marked improvement in starting to walk functional distances. Still a long way to go, however!
