It wasn’t until researching this article that I realized quite how bad the Big Beautiful Bill is for clean energy — reduced royalty rates for fossil fuels, a gutting of fuel economy standards, and subsidies for biofuels & coal, along with the IRA cuts we all knew theconversation.com/big-beautifu...

Perhaps the worst energy provision I’ve ever seen in a federal bill G.O.P. Bill Adds Surprise Tax That Could Cripple Wind and Solar Power www.nytimes.com/2025/06/29/c...

If your “energy bill” helps billionaires get richer while we get dirtier air and higher prices… It’s not giving “big” or “beautiful.” It’s giving bought & paid for. zurl.co/9kkoD @dscohan.bsky.social #StandUpForScience #OBBB #ClimateCrisis

My take on what the House-passed ‘Big Beautiful Bill’ would mean for energy and climate theconversation.com/how-the-big-...

I started my career with an EPA STAR grant, which supported my first PhD student. It’s hard to see how early career environmental scientists, engineers and health scholars will get their start with EPA’s main program for external grants being dismantled. www.nytimes.com/2025/04/21/c...

Wow on.ft.com/4inhS2X China’s CATL says it has overtaken BYD on 5-minute EV charging time

This is a profoundly important attack on American leadership in environmental science. #fightfightfight

The air quality and health models I have used throughout my career have emerged from EPA’s Office of Research and Development. Shuttering it would be a devastating loss. www.nytimes.com/2025/03/17/c...

Please pass to Energy Dept. employees (or others at agencies doing work that Trump and Musk seem eager to scrutinize). I heard through a solid source that employees were asked one day last week to take a break for a few hours at one of the Bureau of Ocean Energy Management offices. 🧵

I think some people hear “grants” and think that without them, scientists and government workers just have less stuff to play with at work. But grants fund salaries for students, academics, researchers, and people who work in all areas of public service. “Pausing” grants means people don’t eat.

New by me in @heatmap.news: The LA fires have accelerated the looming financial crisis facing gas utilities from 2035/2040 to today. Preventing that disastrous cost spiral, though, can help make burned areas safer, easier to rebuild, and more insurable! (1/12) 💡🔌 heatmap.news/ideas/la-fir...

Devastating for scientists and their research, and everyone who benefits from that research. I’m not sure if everyone outside academia is aware that a delay or “pause” in grant funding often means the researchers themselves are lost from the field, along with their expertise.

For folks who are new to BlueSky, I created a climate journalists starter pack (it’s full already but if there are enough folks to warrant a second one I can make it…or YOU can, anyone can!) go.bsky.app/1ivUnG

Electric vehicles, circa 1980

🚨job alert🚨 Would you, or someone you know, like to channel something into thinking rigorously about how safe and electrified housing for everyone might also save the grid? I'm hiring a postdoc! 1-2 years, remote ok, $75k/year. Focus: model scenarios on deep building efficiency & grid impacts

Batteries are reshaping ERCOT’s ancillary services procurement Battery generation capacity has made up 50%+ of awards for reg up and responsive reserves since 2022. In these, coal and gas regularly account for <20% of capacity. #energysky 🔌💡

“The second is that Solyndra had real technology risk, & we don’t take real technology risk anymore at the Loan Programs Office.” - @jigarshahdc.bsky.social in this important interview with @robinsonmeyer.bsky.social. Agreed, & we have a “missing middle” in energy. www.nytimes.com/2024/12/20/o...

France has added a 1.6 GW reactor to its grid after 17 yrs building. It will be taken off line shortly for repairs as discussed in the thread. In that time, the US added 191.8 GW of solar. After accounting for capacity factor (~25%) that's still 30x the capacity added. 🧪🔌💡☀️💨🔋

If you were to write a piece on carbon removal at the end of 2024, would it be about billionaires investing in a "gold rush"? Or about flight from a sector that has no clear and durable business model, in the face of decreasing climatetech funding and net-zero talk? www.nytimes.com/2024/12/22/c...

With the latest Chinese export controls on gallium, germanium, & antimony, you’re gonna hear more about the need to cut red tape (i.e., environmental regs) to help 🇺🇸 extract and secure these critical minerals. It’s a facile narrative rooted in political convenience & not commercial reality. 🧵(1/x)

Already compiled @colinmckerracher.bsky.social charts on the latest battery price index into a slide. Bravo to Colin and team www.bloomberg.com/news/newslet...

The annual BloombergNEF battery survey is out. Quick hits: pack prices now $115 per kWh (and below $100 for cars in China) Almost 2/3 of China's EV models are priced lower than their internal combustion equivalents Great work @colinmckerracher.bsky.social www.bloomberg.com/news/newslet...
