Geothermal for direct heat is the single biggest exception to electrify everything. Energy use is about 50% heat, 30% transportation, and 20% electricity. The less heat you have to put on a winter peaking electric grid, the better.

Just going to brag a little that I just logged my 100th @volts.wtf podcast, and it's the 5th anniversary of the pod, and I love it, and not just because Dave GETS thermal networks, but because of what a warm, goofy, curious vibe he brings to urgent, teeth-grinding, fascinating world of clean energy.

We’re building the future today! @mckennapr.bsky.social reports on HEET’s partnership to expand the geothermal heating and cooling system in Framingham, MA, driving down unit costs and building out the utility business model while keeping customers comfy. Thermal nerds, your time is now!

My latest, for @insideclimatenews.org & @bostonglobe.com; A first-in-the-nation clean energy project will soon double in size as the Trump administration moves forward with a Biden-era grant for geothermal www.bostonglobe.com/2025/12/03/s...

The HEET team won ‘Nonprofit of the Year’ at the NREC Gala last Friday! So grateful to celebrate together with such a wonderful community and work every day with such a wonderful team.

That was fun and thought provoking @fuckupnightsboston.bsky.social

Australia has so much clean energy they're literally giving it away. Meanwhile, GOP is in all-out war to stamp out solar www.abc.net.au/news/2025-11...

Colorado is making sure its residents know the dangers of gas stoves. Its new law sticks yellow warning labels on new gas ranges warning of their “air quality implications” — and other states may soon follow.

Fun fact: 91% of Massachusetts homes have already installed heat pumps!!! Not-so-fun fact: 88% of those MA homes have heat pumps that only work one way—they’re air conditioners. Even-less-fun fact: The 3% of MA homes with heat pumps that heat AND cool have been subsidizing their AC-only neighbors.

This is Rio. She rules my family now. We couldn’t be happier about that. Even if her #BunnyVigilance is sometimes exhausting.

In cold climates, households that switch to heat pumps often pay more than their fair share on utility bills due to high electricity use in winter. Massachusetts may (and should) correct this inequity by discounting winter electricity for heat pump owners. This could accelerate heat pump adoption.

Father Nathan is leading one of the most ambitious, imaginative, and community-oriented thermal network projects I know of - and we’re lucky to have Phil on the thermal beat to share the non-linear path towards making it happen.

Boston is so hot today, it's almost too hot to e-bike....

“Heaven and Earth”: When a church’s heating bill spiked from $100 to $3,000 a month, its leaders decided it was time to ditch fossil fuels for solar and geothermal. Can its plan help its neighbors, too?

Historically low power demand on the New England grid. Why? Rooftop solar.

"Three in five (60%) Americans say they are not familiar with the state or local regulatory body that determines their utility bills. In a separate open-ended question, around 9 in 10 respondents could not correctly name their specific regulatory body." Time to make PUCs famous.

Busy commute this morning

NEW WU POLL: Mayor Wu up over challenger Josh Kraft, 65% to 25%, per Wu source briefed on internal poll Poll of likely voters also has her winning 72% of Black voters and 73% of Latino voters 56% say Boston is heading in right direction, 38% say wrong direction

We’re back (again) baby! We’re going to play the first song Nejem ever wrote, you’ll want to be able to say you were there when it went down… thehavenjp.com/2025/02/the-...

Oh hey Mr. Canary, you takin' a little canary nap? You deserve it, workin' so hard down here in the dark.

DEI is responsible for me forgetting my lunch at home today.

My band The Boundary Objects played #TheHavenJP last night in what is becoming a regular gig. I swear we’re going to get better at being on the internet too…

I don’t mean to boast but

The ineluctable fact is, if you want the most eyeballs, the most clicks, the most "happy users," good journalism is a *terrible strategy*. Truth is expensive to obtain, slow to reveal itself, complicated, nuanced, often orthogonal to neat ideological conclusions. www.nytimes.com/2025/01/16/b...

Tough week for the #mbta Orange Line got me missing the OrangeLineProblems account from back when The Bad Place was kinda good…

A lesson we never seem to learn: you can't cut emissions just by building out renewables. You also have to stop burning fossil fuels. www.nytimes.com/2025/01/09/c...

republicans immediately blamed the fire on democratic environmental policy and leadership. democrats have not said anything about the fire's connection to years of gop climate denialism. this is kind of a fundamental difference to how both sides approach politics.

Yeah what Geoff said.

Good morning to fellow fans of Dave/Volts! I look forward to partaking of more energy nerdery with you here, esp #gastogeo, integrated energy, ethical electrification… with apologies for spamming yr feed w bonus #JPBikeDad / #nowspinning / The Boundary Objects type content…

New report finds: "The Inflation Reduction Act could deliver over $2.7 trillion in net benefits from 2025 to 2035, against $656 billion in costs."

We’re on Volts baby! For an emerging energy nerd this is basically Mt Rushmore. Volts and David understood the thermal network vision early on - no better way to kick off the new year than sharing HEET’s story with the world, and how we’re starting to change the world. “The new hotness” ok!

2004: google answers your question 2014: google offers to sell you something that will answer your question 2024: google makes up an answer to your question 2034: google tells you your question is impermissible and summarily executes you

Hell yes. Very exciting.

Yeah I think this is pretty much my feelings, and not just because I’m the proud parent of a BPS track kid who just set a school record…

Just ludicrous to ask Americans whether they'd prefer a lifestyle that they've never experienced or even witnessed. www.washingtonpost.com/climate-envi...

This has always been my worst fear about climate change: the worse it gets, the more geopolitical chaos it causes; the more geopolitical chaos there is, the harder it is to cooperate to fight climate change. theconversation.com/a-doom-loop-...

New research shows that electrifying US appliances would dramatically improve *outdoor* air quality, to the tune of about $40 billion in health benefits per year. www.rewiringamerica.org/research/hom...

Fun fact: children are not being rushed into gender reassignment surgery. If that's what's holding you back from supporting the trans community, which is under vicious, coordinated attack, good news! You don't have to worry about it. You can just be supportive, without the "but."

On Wednesday, I am talking with the folks working on ***geothermal heat networks*** in the Northeast, including someone from the utility Eversource, which is busy building a pilot project. Got any questions about how these things are shaping up?

Biden's agenda has officially attracted more than $1 TRILLION in private investment into the US manufacturing economy. But that's good news, so media isn't allowed to write about it, so nobody knows. www.whitehouse.gov/briefing-roo...
