This project had a 1.5 year payback: Using Parity's software to more efficiently heat and cool Manhattan apartment buildings. 40% of cost savings from using less electricity by cooling more efficiently, 60% from burning less gas for heat. Energy affordability in action, driven by NYC Local Law 97.

Antora's huge 5 GWh heat battery will use South Dakota wind to make carbon blocks hot enough to later make electricity or heat most any industrial process. Sadly, this project will run corn ethanol processing: Wildly less efficient than just using wind to charge electric vehicle batteries directly.

"I just want to say this, no matter what some people would have us believe, solar panels, heat pumps and EVs are not 'woke'. They are common sense." That's top UK gov't official Ed Miliband. I'm trying to imagine a cabinet-level US official saying the same.

Bylines should include "Headline by Franklin P. Middlebottom III, Senior Editor" so we know who to blame (not the writer), exhibit #87,412

JUST DROPPED: For years I thought industrial electrification potential was limited. How wrong I was. Engineering studies point to 90%+. Long term scenarios support this. Technology is much further ahead than we think. Question is whether policy keeps up. janrosenow.substack.com/p/industry-f...

All of the is obviously bad but another thing that is bad is that i suspect I’m not alone in completely freeing myself from any sense of professional duty to participate in federal grant reviews. People have historically been happy to give huge amounts of time and effort and we might never come back

About 50,000 people were forced to evacuate in Orange County, CA, after as much as 7,000 gallons of methyl methacrylate overheated inside of a tank and became liable to explode over Memorial Day weekend. Now, some residents say they no longer trust the company.

I haven’t posted about this week’s gutting of our NYS climate law just bc it’s so wrenching to witness the destruction of the rule of law on a national level + the maiming of a life- and climate-saving law on a state level. But that’s not emotional maturity so here’s a thread re: what happened. 🧵

Terminal levels of car brain

Here is Tom Steyer personally supporting high school trans athlete AB Hernandez. I don't think I've ever seen a candidate as brave as Tom Steyer in his explicit support for trans folks. It says a lot that it took a self funded billionaire not dependent on donors to do it.

Mega heat pumps can replace fossil fuels in industry. In 2018 the frontier sat at ~165°C & a few MW. By 2024: 280°C & up to 100 MW. +115°C & a 50x capacity jump in six years. The tech isn't the bottleneck. Policy, grid access & power prices are. More soon, sign up here janrosenow.substack.com

New: Climate change literacy has not budged in years. Largely the result of a huge coordinated disinformation campaign. The science is crystal clear: ALL of the warming is due to humans… 1/

Worth mentioning that “more” educated republicans are more likely to blame natural causes. That’s prob because the more educated you are, the more capable you are of researching/ confirming your bias. Anthony Leiserowitz has a paper on this.

We're going to need a CARB and state legislature which are willing to levy the kind of taxes that it takes to end the state's need for fossil fuels, instead of propping up the big oil companies that fund campaigns. calmatters.org/environment/...

I’m a climate scientist. Let me fix this headline. “Nearly a century ago, scientists showed that burning fossil fuels warms the planet. Today, we know human emissions account for over 100% of the warming. Yet dark money and disinformation still work to keep Americans addicted to fossil fuels.”

House Republicans pass Farm Bill that sabotages solar on farms! Gas drilling, data centers, suburban sprawl are all fine on farms but not solar. Farmers use solar for revenue to keep farms operating. This anti-solar Farm Bill is in the Senate. www.theguardian.com/environment/... #energysky

This is what CARB just approved. Love an agency tasked with reducing air pollution actually increasing it!

This is terrible news for fish & wildlife and sensitive ecosystems, and for people’s safe enjoyment of public lands.

I'll say this about Governor Newsom and CARB Chair Lauren Sanchez: At least Governor Hochul had to decency to say she wanted to roll back New York's climate laws in public. Here in California we do the same in private and call it climate leadership.

Any public comment on a proposed regulation, event short and anonymous saying you don't like it/like it, helps. For those wanting to provide something deeper, I saw this resource and really liked it, from the PDF linked on here: www.peer-center.org/research/vir...

but also if this is the point when you realize this, do better. I’ll give a very small pass to the very junior people who got bad mentoring about “rigor” but some of the rest of the community really should be very ashamed

In another world the mutual agreement by refiners and the state that they would like to exit, in line with state legal decarbonization targets, would be a blessing Anyway healthcare, transit, and housing are climate policies

I think at this point you have to treat statements from CARB staff like you do statements from US DOJ prosecutors. They will say anything. They might even believe it.

I was on the fence about Steyer (never for Becerra, just the billionaire thing) but today’s CARB‘s horrible Big Oil give away pushed me over the edge. Steyer may be a billionaire but at least he fucking cares about climate and we need someone who will reverse shit like this (Gov appoints CARB board)

Some personal news — I’m excited to continue my work with the @kleinmanenergy.bsky.social, now as a Schleifer Senior Fellow. I have never had better or more supportive colleagues, and am so grateful to have a home base for public interest policy research.

Breaking: California becomes the latest blue state to retreat on climate goals amid affordability concerns as regulators Friday evening voted to revamp its landmark carbon market to ease costs to the oil industry with $4 billion in incentives. Free link. www.bloomberg.com/news/article...

What would help affordability is building housing and transit, which this guts. It’s just a straight industry giveaway and a fuck you to everyone else.

The affordability crisis is real. So is the climate crisis. We can't solve either without solving both. Fortunately, the best climate policy also reduces household bills. Here's how:

This is not just a US science problem. It is a global problem. And, no, the rest of the world can’t just pick up the slack as I hear some folks saying. The scale of the US science and tech research infrastructure is staggering. I think the NIH external grants alone were nearly 3 times EU Horizon.

Hey, Boston! What are you doing today?! Come join me and a fabulous panel to talk about why your utility bills are so damn high! 11 am on the BU Campus Details here: festival.wbur.org

How do we reclaim our political power in these dark and exhausting times? Check out my interview with comedian & organizer @adamconover.net who talks about how building real political power starts with face-to-face interactions in our communities danarfisher.com/2026/05/30/r...

I want to tell you a bit about why I’m posting here on BlueSky, because I think it matters for whether you trust anything I post. It starts with a job I took straight out of college that shaped everything I’ve done since. 🧵 1/10

@apen4ej.bsky.social is a great recap of all the people speaking out against this- basically everyone but Big Oil. Yet, looks like Big Oil will win. Shame on CARB!!

I submitted my comments. Submit your comments on this insane proposed change: "Changes to how federal funding is allocated and distributed” Docket OMB-2026-0034 (Comment deadline 7/13/26) www.federalregister.gov/public-inspe...

The EU has caved to Trump administration pressure to exempt US natural gas from methane limits. If cutting methane is the climate "emergency brake" it sure seems like no gov't is willing to pull it. My new piece in @nybooks.com on why that means more climate chaos: www.nybooks.com/articles/202...

It appears the rollout Kevin O'Leary's Stratos data center project is not sitting well with Utah residents, who question why they should accept the massive air pollution & depletion of their fragile water supply. Gov. Cox now says the proposed 9GW of gas-fired power will be a mix of power sources.

In his latest post @hamiltonnolan.bsky.social has a line that should be engraved and mounted on the walls of newsrooms (or reporters' home offices) across the land: "Journalism—real journalism—is, above everything else, allergic to bullshit. Bullshit is the mortal enemy of journalism."

As I've said time and again (and @adamconover.net reiterates as only he can do): no one is coming to save us; we're going to have to work together to build community capacity to save ourselves!

"Utilities generally earn a rate of return on capital expenditures but not operational expenditures. That can make expensive infrastructure investments more attractive to utilities, even when operational solutions may lower utility bills, @powerlines.org found." www.eenews.net/articles/ame...

Justice might actually be served. www.nytimes.com/2026/05/29/u...

The SEC today began the process of rescinding the climate risk disclosure rule promulgated in 2024 with broad support from investors. A core mission of the SEC is investor protection, but the Atkins-led version prioritizes loyalty to the Trump/ fossil fuel industry's climate denial script.

A city taxing large retailers 1% to fund community solar, free AC for low-income households, and clean energy job training. Turns out when communities design the policy, they build things that actually help people. vist.ly/55wve via Monica Samayoa at WGLT

Today on Volts: clean electrification is the most dynamic, hopeful sector of the economy, but when it comes to politics, it's a 98-pound weakling, a pathetic junior partner in trade groups dominated by fossil gas. Today's pod is about a new effort to change that. This is a spicy one!

Yes, I know this is not an official Dem Party initiative, just something from one of the core Dem-leaning nonprofits, but that's just cope, y'all. This accurately reflects the absolutely pathetic lack of vision & ambition in elite Dem circles. It's deep in the insular, consultant-led culture.

This is particularly egregious given the massive windfall profits oil and gas is enjoying now. CARB should face serious consequences for this.

In addition to all this bad stuff, the proposed changes to US science funding would create a bottleneck wherein all funding must get political appointees' approval. Appoint very few of those people, or appoint people who deliberately slow-walk approvals, and you slow science funding to a crawl.

It’s bizarre being a policy-oriented researcher in an environment where evidence and public opinion are basically irrelevant to what happens. We’re not informing policy any more, friends; we have to make politics.

We're back, folks! Still not too late to call @gavinnewsom.bsky.social at (916) 445-2841 and let him know what you think of his appointees' plan to transfer $2bn/yr of transit and clean air money straight to the fossil fuel industry, without even a sign that they'll lower gas prices in return!

My teen, who had dreamt of being an astrophysicist, just told me he wants to go to law school because, “Science isn’t going to be a priority in the US in the future…I don’t want a job where I’ll be constantly worried my funding will be taken away.” Gutting. How many future scientists have we lost?
