This is going to be a big old thread where I dump thoughts, reactions, charts etc from the @iea.org World Energy Outlook 2025 :) www.youtube.com/watch?v=wlkP... www.iea.org/commentaries...

Proposal: neighborhood-by-neighborhood annual property tax on every building that uses natural gas, with the money used to help electrify the neighborhood.

A historic turning point for clean heating in Europe: For the first time, in the first half of 2025 sales of heat pumps in Germany have surpassed those of gas boilers. This is a big milestone, demonstrating that the transition away from fossil fuels in our buildings is not just a future ambition.

📺 BDC’s @aconsidine.bsky.social explains to Capital Tonight’s @sarbetter.bsky.social that NY should not pause implementation of the state’s All Electric Buildings Act, as “decarbonization will be more affordable” than sticking with gas. tinyurl.com/mutzj46e #BuildingDecarb #HeatPump #ClimateSky 🔌💡

Change one letter, ruin a candy. Knickers

RCP8.5 debate I miss that climate talk

📣 A bill on @governor.ny.gov’s desk would end NY’s "100-foot rule," which subsidizes new gas line extensions, reports @publicnewsservice.bsky.social. BDC’s @aconsidine.bsky.social & Kristin George Bagdanov explain that ending the rule will save NY ratepayers ~$200M a year. bit.ly/3Whz2GH 🔌💡

Hot take: the innumeracy of Americans is largely due to the use of nonsensical units in daily life.

OK, here we go... I'm excited to launch Climate-Colored Goggles, a newsletter about climate and culture. I'll be writing about climate solutions in pop culture, media & sports. America's most influential storytellers need to get in the game. Sign up here: www.climatecoloredgoggles.com

“Californians purchased 124,755 zero-emission vehicles (ZEVs) in the third quarter of 2025, representing 29.1% of new car sales, the highest quarterly sales share ever reported in California.” www.gov.ca.gov/2025/10/13/r...

I’m fed up with reading climate related media and posts that cover everything except the cause and solutions. Is it any wonder most people are clueless and falling into despair. C’mon guys, lift your games. If you’re not writing about a fast exit from fossil fuels then you’re part of the problem.

The US will struggle to generate the energy it needs to power growth in its tech industry without including wind and solar, according to JPMorgan.

“The economic damage of climate change is already much, much worse than DICE predicted, and the economic cost of policy to fix climate change is actually negative.”

If you haven’t personally experienced a hostile takeover where the new CEO is just there to strip a company for parts and make as much profit for himself and the board as possible before declaring bankruptcy, welcome America. You’re living it now.

Mitsubishi debuts 640 kW heat pump providing hot water up to 90 C #energysky -- via pv magazine global:

For me (total heat pump nerd), one exciting possibility of cities starting their own sustainable energy utilities is that "city worker comes over and installs a battery" is a tiny hop away from "city worker installs your heat pump," which could make heat pumps so much more affordable.

10 out of 13 grants awarded for domestic Heat Pump manufacturing (the IRA’s Heat Pump Defense Production Act Program) are also listed. 🔌⚡ Awards for Gradient, Mitsubishi, and York International appear to be safe.

Two of the most common climate misconceptions I see, even among knowledgeable folks, are that (1) most people aren't worried about climate change, and (2) if they were, they'd act. Not true! Data show (1) most people are worried, but (2) they won’t act if they don’t know what to do-and most don’t.

Roadmap for Overcoming Barriers to Using Natural Refrigerants in the United States www.bpa.gov/-/media/Aep/...

Legacy air-conditioning giant Carrier has a simple solution to ACs stressing the grid: Pair them with a battery that charges up when power demand is low. Here’s how it’s testing the concept.

This new subdivision in Asheville, North Carolina mandates ground source heat pumps for all of the new homes and besides helping to make the buildings more efficient it makes the neighborhood quieter too since the heat pumps are all indoors! #EnergySky

ok but get a heat pump

This week on SHIFT KEY: A stack of electricity techs — solar, batteries, EVs etc. — seem to be displacing fossil fuels across China & the developing world. Is this the start of the "Electrotech Revolution"? Rob & I discuss the evidence with @kingsmillbond.bsky.social heatmap.news/podcast/shif... 🔌💡

LA folks! Get Heat Pumped! Between @volthub.bsky.social's heat pump water heater group buy and @heatpumped.org's heat pump HVAC group buy (www.heatpumped.org/c/groupbuy), now's the time to get that heat pump you've been thinking about for a while!

11/ No amount of bad government policy and turning coal plants back on is going to stop technology that is 100x better. Once people use it, they'll never go back. If you're pushing dinosaurs in 2025, maybe you got a brief reprieve, but the future is going to bite you in the ass sooner than later

10/ Rooftop solar beats buying dirty power from a gas plant miles away. Batteries are smarter + more versatile than backup generators . Induction stoves are sexier + healthier than antiquated gas stoves. Heat pumps deliver better comfort, control, and safety than furnaces + one-way ACs.

1/ 🔌 💡 Just finished my first EV road trip—and I’ll never own a gas car again. 450 miles. $42.42 in electricity. <40 min total charging. A gas car would’ve cost $70. 🧪

Explosive Electrification Growth is Transforming Global Economies We've made electricity for 150 years. Supply is not the issue. The real revolution is devices that turn electricity into "work." EVs, heat pumps, etc. W/@KingsmillBond of @ember_energy youtu.be/yOcqLAamRwo

R290: It appears to me, from googling and reading, that approval starts with risk studies, feeding into ASHRAE 15.2 and UL 60335-2-40 approvals. EPA SNAP approval is then needed. Usually a state then waits for ICC approval, but they can bypass that. Is this correct?

The next Heatpumps & Pints is Wednesday September 24th. Make sure your next furnace/ac is a heat pump. Come on out and get your questions answered! luma.com/pgfibtut

This new 170-home community in Ann Arbor runs on solar, storage, geothermal, and heat pumps—not fossil fuels. Most residents have near-zero or even negative energy bills. All-electric, net-zero neighborhoods like this are the future.

“Sanofi is responsible for the commercialization of Nuvaxovid. The product has a 6-month shelf life and has already begun shipping to healthcare providers and local retailers in the United States.” www.marketscreener.com/news/novavax...

I’m selling my low-mileage EV for $0, after rebates. Nobody wants it. People are so skeptical of rebates that they don’t want a free car that is in excellent condition. There’s a lesson in this for policy makers.

I like this goal. climatetechatlas.com/opportunity-...

Looks like we are going to have a global carbon tax on international sea shipping

A beautiful monoblock R290 heat pump for automobiles, from Bosch. Only water/glycol circulates outside the unit. www.bosch-mobility.com/en/solutions...

R290 moving ahead in California. (I find that a ChatGPT periodic task is a great way of being alerted to these developments.) naturalrefrigerants.com/news/califor...

I keep thinking about this. Between tariffs and this, why would any foreign country want to have anything to do with us?

“Methanol and ammonia as shipping fuels – finds that both ammonia and methanol fuels are now “ready” for commercial deployment (ammonia for pilots, methanol for early operations)” ammoniaenergy.org/articles/glo...

After months of hard work with the Legislature, we've reached a deal to help Californians save money on electricity bills, stabilize our state's gas supply, and slash pollution. We're committed to both cutting costs and speeding our momentum toward a clean, job-creating economy.

Almost 2 years ago, MVV Energie AG started to operate Germany’s largest river heat pump (20MW) in Mannheim. 2 more river heat pumps are to be added of a completely different caliber: a heat pump with 150MW & another with 100MW. HT @jaapburger.eu www.swr.de/swraktuell/b...

“Jetson says its average heat-pump installation cost is way less than the national average: just $15,000.” www.canarymedia.com/articles/hea...

I know. First world problems. But also: burning gas inside around my kids is gross. And inefficient. And slow. And harder to clean. Induction is just better. So no thanks.

Backstory: My fam moved into a new home a week ago. We love it. Except it came with a brand new gas range & oven. And it stinks! Literally. How do people burn shit in their kitchens like this? We installed induction in our old home two years ago and now I can't imagine living without it for long.

In the 1st half of 2025, @climate.noaa.gov 's staff were terminated, shutting down daily operations. Now, former members have joined w/ nonprofit partners to launch Climate.us, where climate info can be safeguarded from politics. Check out our website and join the effort today.

www.nrel.gov/news/detail/... Some updates on Blue Frontier's promising air conditioning technology. This uses liquid dessicants as a form of energy storage, separating the dehumidification and cooling processes, and allowing for the energy intensive portion of dehumidification to be done off-peak.
