Great conversation this week on “Climate, War, and Energy Security” led by @jenniferhadden.bsky.social with participation from @jeffcolgan.bsky.social and fellow panelists exploring geopolitics and energy transition in an era of conflict. Watch the discussion here: drive.google.com/file/d/13j5q...

CSL Director @jeffcolgan.bsky.social spoke with @nytimes.com about the national security advantages of renewable energy in the face of geopolitical turmoil www.nytimes.com/2026/05/12/o...

“For the second time in five years,” @jeffcolgan.bsky.social sed, "geopolitics is creating a crisis for fossil fuels — but the price of sunshine and wind remain free. Renewables have a national security advantage over fossil fuels" Yep. Self-destructive man. Gift www.nytimes.com/2026/05/12/o...

Wind and solar have now beaten fossil fuels in Great Britain for a record 15 months in a row Just a decade ago, fossil fuels were generating four times more than wind + solar Now that's flipped: Since the Iran war, wind and solar generated twice as much as fossil fuels

Wind and Solar have saved the UK £1.7bn in gas imports since the Iran war began. Record renewables pushed gas generation to historic lows in March and April. Wind and solar have now outproduced fossil fuels for 15 months straight, Carbon Brief analysis reveals. www.carbonbrief.org/analysis-win...

Unless they’re tracking Chinese clean tech export data - which I think only Ember does consistently? - all the energy scenarios models etc are just plain wrong.

🧵Today I am releasing a new, open source tool that combines information on energy use, emissions, and health impacts for over 2,000 proposed and operating data centers across the US. It draws on the outstanding work of FracTracker Alliance, @oilandgaswatch.bsky.social, and others. 1/12

New: the Iran war's price hikes on gasoline and diesel alone have already cost American households $278 each (on avg), more than a household's average cost of a week's groceries. A total of $36 billion & rising! Check out the Tracker @climatesollab.bsky.social : iranwarcost.watson.brown.edu

I spoke with @nytimes.com about how OPEC works, in light of UAE's announced departure from the organization @climatesollab.bsky.social www.nytimes.com/2026/04/28/b...

Re-upping this @nytimes.com story on how the Supreme Court blocked Obama's Clean Power Plan, and the consequences far beyond climate policy. "not a single justice ... mentioned the dangers of a warming planet as [something] the court should consider." www.nytimes.com/2026/04/18/u...

Trump -> Iran -> Chinese solar 🛢️💡🔌🌎

Great to see @politico.com using data from our Iran War Energy Cost Tracker for their reporting www.politico.com/news/2026/04...

We could have both science and exploration, both robotic and human. "We @climatesollab.bsky.social track the extra fuel costs the Iran war has imposed on American households. As of today, the total is $24.6 billion, more than the annual budget of NASA." iranwarcost.watson.brown.edu

Imagine if we had just *wasted* the Artemis II space project. We @climatesollab.bsky.social track the extra fuel costs the Iran war has imposed on American households. As of today, the total nationwide cost is $24.6 billion, more than the annual budget of NASA. iranwarcost.watson.brown.edu

I spoke with @alexjn.bsky.social @motherjones.com about the Trump admin's "casual relationship with truth." Maybe I need to learn to be more discrete?? 🤔 www.motherjones.com/politics/202...

New work on batteries and EVs in Europe by @palmapolyak.bsky.social, who was at a CSL workshop at Brown University this winter led by @jenniferhadden.bsky.social

CSL Director @jeffcolgan.bsky.social spoke with CBS News about the rising costs of fuel due to the war with Iran www.cbsnews.com/boston/news/...

What if one of the most powerful climate solutions isn’t technology—but conversation? This week in Talking Climate, we're talking about hairdressers inspiring climate convos, war supercharging emissions, and more positive content creators to follow. Read on!

Receiving the Grawemeyer Award for book States and Nature has to be one of my best professional memories.

Headline should be that polarization worsens news.gallup.com/poll/708050/...

I talked to @grist.org about how diesel fuel prices are quietly costing the USA billions, thanks to its war on Iran. Based on our new Iran War Energy Cost Tracker at iranwarcost.watson.brown.edu grist.org/business/the...

"The war has cost the U.S. economy roughly $17 billion solely by increasing prices for gasoline and diesel fuel, the estimate finds. These higher prices have cost each household about $129 on average." - @climatesollab.bsky.social: heatmap.news/energy/iran-... via @robinsonmeyer.bsky.social 🔌💡

Nice to see the U.S. Senate Foreign Relations Committee already using the Iran War Energy Cost Tracker @climatesollab.bsky.social @watsonschoolbrown.bsky.social iranwarcost.watson.brown.edu

New: the Iran war is driving up gasoline and diesel prices, already costing American households $130 each (on avg), a total of $17 billion -- and it's rising fast. Imagine if we'd spent that on clean energy instead? Check out our real-time updating Iran War Energy Cost Tracker

New: the Iran war's price increases on just two products, gasoline and diesel, has already cost American households $130 each (on avg), a total of $17 billion -- and it's rising fast. We have an Iran War Energy Cost Tracker @climatesollab.bsky.social. Check it out: iranwarcost.watson.brown.edu

Revolution Wind has started delivering electricity to the New England grid, @browndailyherald.bsky.social reports, with commentary from IBES faculty affiliates @jeffcolgan.bsky.social & @bradmarston.bsky.social: @watsonschoolbrown.bsky.social @climatesollab.bsky.social @brownphysics.bsky.social

A bit of good news in dark times: Revolution Wind is now delivering clean electricity to New England. I spoke with @browndailyherald.bsky.social about the energy security advantages of wind while Hormuz is throttled. 🌎🛢️ www.browndailyherald.com/article/2026...

Great to see new books by CSL members @jenniferhadden.bsky.social and @kathrynchelminski.bsky.social on display at ISA2026! (And hat tip to Jen's co-author @sarahbush.bsky.social )

Shout out to the great resources by Greenlight America on supporting solar and wind energy at the local level and tips for combatting climate misinformation www.greenlightamerica.org/resources

Thank you so much to Brown & @climatesollab.bsky.social for having me yesterday. Hello Boston! I look forward to seeing everyone this afternoon (4 p.m.) at @bostonu.bsky.social www.bu.edu/ioc/2026/02/... (register here) and @mitdusp.bsky.social tommorrow

Where will Americans live in a climate-changed future? Thank you to Dr. Jesse Keenan for joining us yesterday to discuss his recent book, North: The Future of Post-Climate America, and discuss how climate migration is already reshaping cities, markets, and politics across the country. 🌎

SCOOP: Alabama might be the first state to ever ban new solar farms. Why? People are upset about a gigantic solar project that would power a Meta data center. Turns out when you tie solar to data centers, it can quickly become less popular!

Here we are again. In 2022–23 Europe spent €800bn subsidising fossil fuels to keep energy bills down. Imported fossil fuels mean volatile prices. The real solution is not new suppliers but a shift to clean energy.

This news from the Pacific is part of a trend: Climate change is going to be bad for ex-military bases around the world, many of which are former US bases with toxins direct.mit.edu/glep/article...

Pleased to be quoted in today's @nytimes.com, supporting their reporting on the Iran war with a China angle: “China’s push for renewable energy is not motivated by the environment but by the need for energy security and also as a driver of growth.” www.nytimes.com/2026/03/14/b...

President Macron making the case for renewables in light of the US-Israeli attack on Iran, "Everything we do to move towards transition is also about reducing our dependence and therefore our exposure to geopolitical risks"

After the Ukraine invasion, Europe's energy prices skyrocketed. Our research @climatesollab.bsky.social showed the excess fossil fuel costs for Europe exceeded €1 trillion. Three years ago we urged leaders to go green on energy faster, for the sake of economic security. If only they had listened!

I spoke with CBC News again (on March 8) about the Strait of Hormuz, its significance for oil, and the risks the Trump team are creating @climatesollab.bsky.social @watsonschoolbrown.bsky.social @bridgingthegap.bsky.social @brownupolisci.bsky.social @brown-ibes.bsky.social

I spoke to Mother Jones about petro-imperialism, the role of oil in recent US military actions, and the national security advantage of solar & wind. 🌍🛢️ www.motherjones.com/politics/202... @climatesollab.bsky.social @watsonschoolbrown.bsky.social @brown-ibes.bsky.social

Where will Americans live as the climate shifts? Join CSL for a talk with Jesse Keenan on his new book *North: The Future of Post-Climate America*, a bold look at climate migration, resilience, and the regions poised to thrive. 📅 Wednesday, March 18th, 1-2pm EST 🔗 events.brown.edu/event/322742...

In the absence of reliable data, driving blind, do you think actuaries will err on the side of higher premiums or lower ones? 🤔 (2/2) www.eenews.net/articles/us-...
