The Independent System Operator’s perspective on offshore wind should be heeded: “These projects are particularly important to system reliability in the winter when offshore wind output is highest and other forms of fuel supply are constrained.” isonewswire.com/2025/12/22/i...

The funny thing about a recent FT oped on electricity prices is how the piece disqualifies itself. Good reform requires knowing the arguments in favor of different aspects of the existing system (in this case, how spot electricity markets work).

New paper out today in Nature Energy! We evaluate how Congressional proposals for policy-driven transmission expansion would shape U.S. electricity costs, emissions, and reliability. Big implications for climate and grid planning. rdcu.be/eS7lj #EnergyPolicy #Transmission #CleanEnergy

Twitter accounts are based in Russia. BlueSky accounts are based in homes with, frankly, too many books, plants, obsolete cables, and pieces of rustic pottery, that could do with a bit of a tidying up, to be honest.

Good to see climate policy mixes are in the spotlight in this year's Ten Insights in Climate Science! Climate policy is essentially about choosing the right policy mix. 10insightsclimate.science/year-2025/po...

To quote my friend @drkatemarvel.bsky.social, climate change won't make humanity extinct but we can do better than "not extinct". Raise your standards people!

This adds to a growing body of literature that very clearly shows the use of short run marginal emissions rates is NOT a credible measure of consequential emissions impacts of various actions. Here, it's rooftop solar... 🔌💡

Academic publishers have a natural monopoly and should be regulated as utilities. They are housed in a handful of countries, so concerted government action should not be difficult.

Out now is an updated version of our working paper on optimal climate policy choices in liberalized power markets. Do climate policies bring risk-mitigation co-benefits? We find that in some cases they do, & that this matters for the CO2 price vs. subsidies debate. papers.ssrn.com/sol3/papers....

More on our important election here in GA. Early voting has started. There are 2 commissioners positions in the ballot. Don’t like how high your power bills have gotten? This is a chance to vote for 2 people that can stand up to GA Power!!

There is an important election opportunity for Georgia voters to have their say on the future of electricity regulation in the state. Turnout is typically incredibly low. Good break down here. youtube.com/watch?v=UgvE...

Modeling Monday: How clean are EVs, really? Short answer: it depends on the question. Attributional vs. consequential LCA, average vs. marginal, short- vs. long-run... the metric can flip the answer. 1/🧵

Some thoughts on the strategic logic behind Kemi Badenoch’s announcement that she’d scrap the Climate Change Act (CCA). It serves two functions: 1️⃣ It appeals to lukewarm pivotal voters in marginal seats sceptical of costly green measures. 2️⃣ It is designed to www.theguardian.com/environment/...

Baseload you say? ieefa.org/resources/ne...

States should make sure data centers are accompanied by more zero-fuel-cost capacity and transmission.

We live in a world where AI companies are working on tools that allow people to make ever more realistic deepfakes, but dont think to apply their resources so autocorrect can recognize and add apostrophe to “don’t”.

"In addition to “climate change” and “green,” [Department of Energy] EERE forbid officials from using “emissions” to avoid the implication that they are a negative." If "emissions" are a forbidden word, I guess "cost" is next, cause that's pretty negative? www.politico.com/news/2025/09...

Can confirm.

Remember those data centers raising electricity prices? In many cases, they are also getting taxpayer subsidies. “At least 10 states already lose more than $100 million per year in tax revenue to data centers” goodjobsfirst.org/cloudy-with-...

1) New paper! Replacing US fossil-fueled vehicles & appliances with electric versions could improve health & climate outcomes, but could cost up to $790 billion in distribution grid reinforcement. Strategic demand-side management could cut 2/3 of those costs.🔌💡 www.sciencedirect.com/science/arti...

Excited to share a new paper I got to help out with! How much emissions do EVs cause through the electricity they consume? How do we know? Our paper shows that frequently used metrics *over*-estimate EV emissions. iopscience.iop.org/article/10.1... by Riti Bhandarkar, Qian Luo, @jessedjenkins.com

It's increasingly common to see a justifiable worry that AI data centers will raise electricity prices for ordinary consumers. What should we do about that? There's a lot of remedies, but one overarching solution is to build more wind, solar, and batteries. Why? I am so glad you asked. 1/5

What do real landowners and local officials think about wind and solar projects? We asked them in our last report that focused on Texas: txrenewables.net See below for what they said.

This question came up again - is removing wind/solar subsidies, like Congress has done, bad? Shouldn't markets reflect "the full cost"? Here is a succinct answer 👇

As a reviewer who gets ~15 review requests/week, an editor that has to send 50 requests to find 2 reviewers, and a co-author that watches really good papers get desk rejected, it sure feels like the academic journal system is broken. I have some thoughts on what a better system would look like.

REPEAT Project just completed our rapid analysis of the impacts of the Senate-passed version of the One Big "Beautiful" Bill (OBBB), which the House is considering now, on the US energy sector and emissions. Still working up full report, but here is a sneak peak... 🔌💡 🧵

You love to see it:)

Eliminating welfare-increasing subsidies on wind and solar is still horrible. We can't let the Overton window be shifted so that simply defeating an absurd new tax on wind and solar is enough of a compromise.

Debate and amendments continue today on the Republicans' One Big Horrible Bill. There's still time to make it less bad, especially on energy provisions. If you want energy abundance, cheaper electricity, less pollution, NOW is the time to CALL Senate offices and tell them to... 🔌💡

The Senate now wants to go from subsidizing wind and solar, which makes sense, to taxing them, which very much doesn't. There is no doubt that this bill will raise electricity prices across America. www.nytimes.com/2025/06/29/c...

If writing is how we discover what we don’t fully understand, we might see AI supercharge the Dunning-Kruger effect.

I am hearing coal plant developers in China often don't assume any strengthening of the CO2 pricing system there, which makes me question its promise. These are niche reflections on CO2 pricing. 1/5

The Senate Finance committee just dropped their draft text for the Republican budget bill. www.finance.senate.gov/chairmans-ne... Like the House, it is hot trash and terrible for America. But it is marginally better for clean energy credits. Some key details... 🔌💡 🔌🚗

Exactly as I said after the blackout: voltage regulation was issue, not a lack of spinning inertia, as so many quickly speculated (or asserted). It was an off peak spring day, plenty of cheap solar available, and the grid operator cut it too close, failed to commit sufficient voltage regulation.🔌💡

It's almost as if renewables+storage have the underrated benefit of giving us a risk hedge against natural gas volatility.

On the House tax bill: “It’s a big win for China and bad for American manufacturing,” said Mike Murphy, a veteran Republican political operative who is chief executive of the EV Politics Project. www.nytimes.com/2025/05/23/b...

The House tax bill is bad for American manufacturing.

An important consequence of the House tax bill is that it will likely increase energy bills for households and businesses.

Interesting new paper on climate policy mixes finds no equity-efficiency tradeoff b/n CA's CO2 price and Low-Carbon Fuel Standard. CO2 pricing is similar in terms of equity to the LCFS, but only after CO2 price revenues are recycled back to consumers. www.sciencedirect.com/science/arti...

What exactly led to the Spain-Portugal blackout is still unknown, but this pod provides a great explanation of the power grid dynamics that are involved in these kinds of events. #energysky You will come away smarter, & not b/c you will know "the answer" but b/c you will know the questions to ask👇

What is happening to US clean energy manufacturing investments? Since Trump took office, 14 projects totaling $12.2 billion in investment and 14,115 jobs have slowed. My students @wellesley.edu and I are tracking it. Details 🧵 below. 🔌💡🔌🚗 www.the-big-green-machine.com/post-trump-s...
