This is great news, and also the energy world's love for "two lines crossed on a graph" news stories cracks me up.

Across 400 NYC apartments, Entech's sensors and AI software drove boiler efficiency gains that slashed emissions by nearly 25% and generated more than $5 million in savings for property owners during the winter heating season. Pretty cool. from @kbrigham.bsky.social heatmap.news/climate-tech...

In April I reported on some concerning conduct within the GHG Protocol. Now, Danny Cullenward, a member of its oversight board, has resigned in protest, accusing GHGP of handing standards development over to “a secret, industry-dominated drafting process.” heatmap.news/carbon-remov...

we're already playing!

The coming wave of big tech IPOs is going to make a whole lot of people very, very wealthy. If you’re one of them, @kbrigham.bsky.social suggests, perhaps you might want to consider funding some first-of-a-kind climate tech? heatmap.news/climate-tech...

though the priority for much of this new philanthropic capital will likely be AI safety, because of the obvious risk of existential doom, an entire galaxy of paperclips, etc. 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎 📎

the AI boom is minting a new gen of billionaires, some of whom will soon be searching for worthy philanthropic causes. i spoke with leaders in the climate philanthropy world who see a chance to channel AI wealth into decarb and adaptation efforts that might otherwise never get off the ground

If you change “may” to “will” I agree with this headline. www.cnbc.com/2026/06/06/c...

“.. The public has swung 49 points against data centers in just nine months, underscoring the heightened political salience of the facilities and the AI industry that they embody.” @heatmap.news heatmap.news/politics/ame...

some very good graphs (and words) by @andrewdessler.com here

every week there's another announcement about a company launching something into orbit that would have sounded like pure scifi a few years ago. and climate tech investors are eating it up. data centers in space? beaming solar power to earth? orbital energy infrastructure? check, check, and check!

for all you weirdos still on here before the long weekend, check out all the climate tech deals this week! we've got $$ to “turn roads into power plants," gridtech, plans for a nuclear IPO, and more 💫

Does new transmission actually move the needle on clean energy? Here's a month of California data before and after SunZia came online. Wind is up by a third, and gas down by a third. Judge for yourself.

I went long on Span, the electrical panel company scaling the concept of utilizing the existing capacity on the grid from homeowners saving $ installing EV chargers to utilities saving $ avoiding transformer upgrades to AI users hunting for compute heatmap.news/energy/span-...

So many great ideas! One of the reasons many people drive in Seattle is to access outdoor recreation. Then they have a car so they start using it for a lot more trips. Let’s increase access to our natural beauty and serve rural transit riders at the same time!

The story of climate tech funding in 2026 is a tale of two points on the development curve, @kbrigham.bsky.social writes. While later-stage funds are still making investments, early stage funding is suffering, which could spell trouble in the years to come: heatmap.news/climate-tech...

Just learned that there is a "North American Wood Pole Council." It promotes "up-to-date scientific and economic information" about wood utility poles. "Wood poles are part of our overall culture." It has a coloring book. woodpoles.org

with drought conditions worsening and the iran war turning desalination infra into a military target, there's a cohort of startups rethinking how and where to build this decades-old tech to make it more resilient -- and ideally, cheaper

interconnection queue reform in PJM was supposed to be a boon to solar. instead the new queue is largely gas. what happened? heatmap.news/energy/pjm-q...

yet another SF climate week is in the books! here are some tidbits, insights, news items, and what have you from the week

Critical story and impressive reporting - Emily has summarized an intensely complicated situation beautifully. The stakes are massive: whether we get an accurate picture of how much is being emitted, where. Misconduct and nontransparency within GHGP should alarm everyone who works on climate.

today @octopus.energy and battery manufacturer and VPP provider Lunar Energy announced a partnership to launch a residential battery-powered retail electricity plan

SUCH a fun conversation. Have been thinking about it since we did it. Thanks so much to @volts.wtf for having me on.

New this morning from @kbrigham.bsky.social, an EXCLUSIVE on the latest update to the Speed & Scale climate action tracker: heatmap.news/climate-tech...

Microsoft is the anchor of the carbon removal market. It bought 45 million tons of carbon removal last year; the next largest buyer has purchased 1.8 million tons *ever.* So what happens now that Microsoft’s paused buying? Spent the week talking to folks about it: heatmap.news/carbon-remov...

bill gates' climate-tech VC, breakthrough energy ventures, recently backed a startup building quantum computers for AI. in this week's installment of funding friday, i ask: is that really climate tech? and more! heatmap.news/climate-tech...

New from me: No increase in global coal power generation after Hormuz closure - solar and wind growth covered the fall in gas-fired generation. The record buildout of clean energy in 2025 helped mitigate the impact of the Hormuz closure.

Here’s some good journalism news (for once).

I spoke with one of the world’s leading experts on anti-tech extremism about the rising violence against executives and politicians who support AI data centers. Our conclusion? Expect a lot more future violence over AI data centers, period. My latest for @heatmap.news

On Wednesday, I'll be recording a special pod with @robinsonmeyer.bsky.social of @heatmap.news. Volts doesn't really cover breaking news, but Heatmap does, so we'll just be discussing ... things that have happened recently. Turns out lots of things have happened recently. Got questions for Rob?

Exclusive: The Iran war has already cost Americans $17 billion at the pump, draining demand out of the economy and sending prices soaring more than $1.40/gallon in some states, per a new Brown University analysis heatmap.news/energy/iran-...

as the world stares down a transformer shortage, incumbents are racing to add capacity. but a wave of startups is also tackling the problem from first principles — either rethinking the manufacturing process and supply chain or overhauling standard transformer designs in favor of solid-state tech

The longer you work in policy-adjacent spaces, the more outraged you get when anyone suggests that individual (or even industrial) conservation measures can move the needle on water use, especially in the West. It's cows. It's all cows. (And the alfalfa that feeds them).

the Iran war poses a paradox for climate tech. disrupted fossil fuel supply could speed the shift to renewables. but the Gulf also funnels lots of oil $ into climate-focused funds. as that revenue tightens, the climate tech capital stack could also take a hit

Many of the Persian Gulf countries currently taking huge hits to their energy infrastructure and oil revenues are also big investors in climate tech. Here's @kbrigham.bsky.social on how the war could scramble the capital stack for the most ambitious climate startups: heatmap.news/climate-tech...

For the launch of our new Electricity Price Hub, I wrote about why rates and bills are not the same. We talk a lot about why rates are higher in some places than others. But some places (i.e. the South) have low rates and high bills, and demand different policy fixes heatmap.news/energy/elect...
