New paper! Heat-pump water heaters could cut energy costs and pollution, but installs often require 💰 electrical work to accommodate backup resistance heat. My student Levi Premer developed prediction and control software to eliminate the need for backup heat and ⬆️ efficiency and flexibility. 🧵1/

As tens of thousands across America protest the violence that ICE sows with impunity, federal agents shot and killed another person in Minneapolis today.
ICE terrorizes our cities. ICE puts us all in danger. Abolish ICE.

The attorney general is threatening a state that the federal government will continuing murdering its citizens in the streets unless they provide access to state voter rolls, a lawless demand which is the subject of ongoing litigation.
Fox News: "I've gotten my hands that AG Bondi said she sent to Gov. Tim Walz. It is strongly worded. The AG calls for the governor to support the men and women of ICE, to repeal the state's sanctuary policies, and to allow the DOJ to access state voter rolls."

If ICE is emboldened to carry out extrajudicial killings of American citizens in broad daylight, imagine what's happening to the tens of thousands of people being held in makeshift detention camps across the US without cameras, attorneys and organizers

I recommend not watching the videos, which are chaotic and gut-wrenching, and instead going through Bellingcat's analysis.
This man appeared to be zero threat, while the officers were overly-aggressive, agitated, and clearly primed to used lethal force.

Multiple federal agents can later be seen struggling with the man who is shot. One federal agent is seen approaching with empty hands, before reaching around the man’s waist.

Too obvious a point even to make, perhaps. But there was no “unrest” in Minneapolis before ICE and CBP showed up. ICE and CBP are the cause of the chaos…and the killings.

This was also my father, who eventually moved to the US and became a historian of WWII. We lost him a couple years ago and have noted it's a consolation he didn't live to see this happen - he was so proud to be an American. I hope he'd be even prouder if he could see the bravery of Minnesotans.
My parents were kids in Norway during the Nazi occupation. People being disappeared and killed on the street. I always thought one of the worst parts would be not knowing how long it would last or if it would ever end. I knew it was five years. They had no idea.

Quite unfortunate that federal policies & greedy corporations, some literal monopolies (utilities) & others effectively monopolies (Big Tech), have created an electric affordability crisis so salient that implementation of innovative state policies to address climate change have had to be delayed:

We as voters can also rally outside their offices demanding that they do this. You don’t have to wait until ICE comes to your community.
"What can Democrats actually do?"
- Vote against funding for ICE and DHS
- State that any ICE officers who commit crimes under Trump will be prosecuted to the full extent of the law
- Encourage cities and states to refuse to cooperate with ICE
- Explain ICE is part of Trump's tyranny

Maybe a good time to re-share my thread about how a skeezy crypto company *made profit* during the massive Texas winter freeze of 2021 by first seizing a massive amount of grid capacity and then getting paid to trickle a tiny amount back to freezing, dying citizens
I really couldn't help but dig into this - and I think it's fair to say that the Economist headline *is actually correct* - and I'm going to explain why in a short thread.

Watching what is happening right now in MN (and elsewhere in USA) is frustrating, depressing, enraging, all of it. Especially as an American citizen living outside the country.

To those blaming Walz for not mobilizing the Guard, he did that six days ago. I have to say it's disturbing to see people angry at Walz instead of the government agents that just executed a man. As though we should all be experts about what to do when a secret police force invades an American city.

ICE has now carried out two summary executions of innocent people in the streets of an American city.
If you work for ICE, there's no denying that's the mission you're supporting now. You don't get to claim in one year or ten or twenty that you didn't know what ICE was doing. You're complicit.
