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

Electricity affordability is a major concern. A new paper with grad student Fischer Espiritu Argosino shows renewable policies aren’t driving price increases once you control for confounders. ceepr.mit.edu/workingpaper... #EnergyAffordability #ElectricityPrices #Renewables #PolicyResearch

New blog post today on work with @knittelmit.bsky.social and @cwolfram.bsky.social. Climate inaction is *already* a big expense affecting US households costs; the most important mechanism is the impact of climate-related natural disasters on housing costs. legal-planet.org/2025/11/20/c...

Climate inaction is ALREADY a big expense affecting US households' costs. One of the biggest? The impact of climate-related natural disasters on housing costs. New post and research by @kclausing.bsky.social @knittelmit.bsky.social @cwolfram.bsky.social legal-planet.org/2025/11/20/c...

Faculty Director @knittelmit.bsky.social is speaking at the New Deal Leaders 15th Annual Leaders' Conference. Sessions include in-depth policy conversations on key issues, including #housing, #education, #cleanenergy, #AI, + more. buff.ly/sjRJmp8 📅 November 19-21 📍 Washington, DC

The podcast version of our BPEA paper on “Who bears the burden of climate inaction?” (thread below, with @cwolfram.bsky.social and @knittelmit.bsky.social) just dropped . www.brookings.edu/articles/how...

An MIT CEEPR paper by @knittelmit.bsky.social, @gibmetcalf.bsky.social and @shereeinsaraf.bsky.social looks at the impacts from a Gas-to-VMT Tax Shift. Check out the full paper at the link below: ceepr.link/42R44sv

🧵 (1/7) With @knittelmit.bsky.social and @cwolfram.bsky.social, happy to announce our new paper on “Who Bears the Burden of Climate Inaction?”, just posted for BPEA @brookings.edu. We find large climate cost impacts that vary by both geography and income. www.brookings.edu/articles/who...

Any #Warsaw recommendations? Food and tourism.

First they came after the undocumented immigrants' speech, who had few constitutional protections, and I did not speak out— because I was not undocumented.

From my awesome co-author Jen Alix-Garcia: thehill.com/opinion/ener...

Leveraging input from stakeholders across the EV ecosystem, a team of @harvardsalata.bsky.social and MIT CEEPR researchers recommends how to speed deployment of new charging technology to rapidly expand the EV market. salatainstitute.harvard.edu/deploying-pl...

The #tradewar is on. Real-time electricity prices doubled few minutes after midnight EST in New England. 🔌💡

Submit your interesting paper to the Spring @nberpubs.bsky.social EEE meetings. The great #PaulinaOliva and @stevecicala.bsky.social ky.social are sure to pick an amazing set of papers. DEADLINE IS IN 9 DAYS!! March 27-28, 2025 conference.nber.org/confsubmit/b...

You should listen to this podcast! You can skip the most recent one, but the others are worthwhile! #energysky #econsky #climatesky energy.mit.edu/podcast/the-...

My amazing post doc, Juan Senga, presenting our work using a revealed preference argument to estimate the non-engineering costs associated with building transmission at the #CEEPR workshop.

Looking forward to our #CEEPR fall workshop in DC. A great lineup of papers and our largest registration ever! 1/3 academics, 1/3 industry, 1/3 policy makers. ceepr.mit.edu/wp-content/u... #energysky

Frying a turkey in a log cabin in the middle of a New Hampshire forest? What can go wrong!? At least there isn’t an open flame. Happy #Thanksgiving everyone!

A quick calculation on #Trump's #tariffs. We import ~$900B from Ca and M. 25% tariff. Assume a 75% pass-through (low?), that's a $1,000 tax on the avg US household. We import $430B from China. 10% tariff => $250/HH. Here comes a $1,250/year tax on US households? #TrumpTradeWar

Hey #energysky #econsky #academicsky, If you haven't tried, try #Google's #NotebookLM podcast feature. Just upload a paper and hit go. I plan to use these for my class. It seems to do a decent job at AI generating the podcast.

My son and I always behave myopically at hotpot. The ride home is always painful.

Excited to share our new paper: "Using Information to Curb Racial Discrimination" with Don MacKenzie, Michiko Namazu, @ozaltun.bsky.social, @dansvirsky.bsky.social, & @stephenzoepf.bsky.social www.nber.org/papers/w33118 #EconSky #EnergySky #TechSky #ResearchSky

Highlighting rider ratings can reduce ride cancellations for groups vulnerable to bias, but other relevant information has a smaller, non-significant effect, from Christopher R.

Faculty director @knittelmit.bsky.social in a @nytimes.com feature on oil companies retreating from clean energy: “If we want to combat climate change, we need to make it in the firms’ and consumers’ self-interest to produce and buy the low-carbon alternatives” www.nytimes.com/2024/11/18/b...

@mitsloan.bsky.social was kind enough to write out our recently published paper in #ScienceAdvances on energy poverty and the disconnect with where #LIHEAP allocations go. Work continues; please let me know what you think! #energysky #climatesky #econsky #policysky mitsloan.mit.edu/ideas-made-t...

My son’s first #Steelers game. It was a good one. My brother (pictured) and I were on the season-ticket waitlist for 24 years….

Off to Pittsburgh!!! Go #Steelers.

My ancestors that lived here in the <1500s would be proud. But Knittel means “rude person” in old German, so their neighbors might not have cared.

New York will soon be a more better place to live...and visit...and work...

Hey #edusky and #climatesky, Our MOOC that teaches strategies for high school teachers to work more climate into their curricula is LIVE. Sign up now. It's free!!! Or you can pay $49 to get an official certificate! www.edx.org/learn/educat...

Hey #edusky, #energysky, #climatesky for the past few years we at @mitofficial.bsky.social have been developing a #highschool #climatechange curriculum. We’ve teamed up with 5 amazing curriculum developers, all current MA HS teachers. Climate Action Through Education. Learn more at cate.mit.edu

Behavioral nudges in a biopharmaceutical workplace reduced plastic waste by 70 percent, cut freezer door alarms by 80 percent, and improved recycling practices by 40 percent, from Cappellucci, Ha, Honig, Knittel, Vetter, and Wilner https://www.nber.org/papers/w33120

New paper! Wholesale electricity Ps vary wildly across hours, locations, seasons, etc. Yet, >90% of residential consumers face a single price!! The inefficiency from this mispricing is expected to grow as we decarbonize the grid. Can time-of-use pricing and/or critical peak pricing save the day?

New paper alert! "Small Changes, Big Impact: Nudging Employees Toward Sustainable Behaviors" w Laura Cappellucci (#Takeda), Lan Ha (@mitofficial.bsky.social -> @rockstargames.com, Jeremy Honig (#Takeda), Amy Vetter (#Takeda), Richard Wilner (#Takeda) www.nber.org/papers/w33120 #energysky #econsky

My first BlueSky post. New paper alert! With #JohnAsker, #AllanCollardWexler, the great #CharlotteDeCanniere, and #JandeLoecker. Note that Charlotte is on the market this year, so you should hire her. @energy.bsky.social @energy.bsky.social #climate t.co/hp7tpq5t7X

The OPEC's market power reduced global carbon emissions by limiting oil production, offsetting welfare losses from distorted production allocation, and lowering climate damages, from Asker, Collard-Wexler, De Canniere, De Loecker, and Knittel https://www.nber.org/papers/w33115
