@clawrence @ACEEEdc published a study on this, and the paybacks are less than 2-3 years on replacing air conditioners with heat pumps in electric resistance households: eia.gov/consumption/re… It's even better in Southeastern States which need more heating!

I recently learned we have 12GW of electric resistive heating in ERCOT. Moving those folks to heat pumps or gas would have a huge impact on winter electric loads.

@TermPowerTrader @clawrence You can do it at the state level using Highlights for Space Heating and Highlights for Space Heating Fuel here: eia.gov/consumption/re…

@clawrence I'd love to see a version of this map that splits out electric resistance heating vs heat pumps but I imagine the uptake of heat pumps so far isn't enough to make a meaningful dent in the map.

@BloombergME @mattyglesias @JakeAuch Efficiency requirements are not limiting housing---focusing not only saddles residents with higher bills down the line but distracts from actual solutions like zoning reform. aceee.org/blog-post/2025…

@mattyglesias @JakeAuch The math is a lot shakier with existing housing stock, but not with new builds.

@ryanaus33 @dieworkwear GoodOnYou.eco rates brands on labor and environmental practices

@dieworkwear What are your thoughts about the quality of Quince clothing? Both generally and specifically their Mongolian cashmere. I don’t place much value on something simply because it’s made in the US. But I would like to avoid supporting companies that promote poor labor environments.

when people say "luxury is dead," they mean the craftsmanship you get for the price paid. this is not even on your radar bc your reference points are just branding, pricing, and celebrity. if something is expensive, you think it's luxury.

Nerdy But Important: Thermostat Settings for Hybrids Josh Green, CEO of Mysa Thermostats, is talking at this month's Hybrid Heating Coordination Group about how various settings of hybrid/dual fuel HVAC affect comfort, performance, and operating costs. Want to join us? Comment or DM me and I'll get you the meeting link. It's tomorrow (Friday) at 2 PM EST. Give me your email and I'll get you on the list so you get the recording of the presentation. It's funny to be excited about such a nerdy topic, but I really am! It's about half HVAC pros and half policy wonks, so it's a big tent!

Solar’s price drop is astonishing: panels are now 98% cheaper than when I first analyzed them in 2004. Today, building a fence with solar can be cheaper than using wood.

@YIMBYLAND I lead ACEEE Buildings Program and have a mechanical engineer on staff, and also tracking bills in Texas (on other topics). Would appreciate connecting!

Also, DM me if you’re a Mechanical Engineer that wants to work on reurbanizing America.

TEXAS SENATE JUST PASSED HOUSING ON COMMERCIAL ZONED LAND STATEWIDE 🤯 This law legalizes development & preempts cities over 150k from imposing - Density limits below 36 unit/acre - Heigh restrictions below 45ft - Setbacks over 25ft - Parking reqs over 1/unit THIS IS MASSIVE

@PoliticsAndEd Washington, DC had shuttles running in two suburban areas, but recently canceled them: mwcog.org/assets/1/6/DC_…

Public transit as on-demand Uber-like ride share programs are so expensive to run. This one in suburban Orange County costs almost $60 per rider. Another in So Cal was $80 a rider. Do these work anywhere?

@ScottRobertsDC I remember this the opposite way---even numbers on the right when walking towards the Capitol (decreasing numbers).

sharing this info with #BloomingdaleDC since no one seems to know these rules

@energysmartwv Wow---super surprising to see the northeast states leading in market penetration! In the 2020 RECS state ownership data NH, VT, ME, and CT are not even shown due to not enough penetration. Looking forward to hearing more!

The midwest lags the nation in heat pump ownership at only 20%. Hybrids (furnace + heat pump rather than furnace + AC) are the fastest way to shift this. Every one way AC that gets replaced will be a 2 way AC aka heat pump. The rest of the country is around 40-50% penetration, so still a lot of improvement. This is from a great study by Mitsubishi/Trane. We'll be discussing this study on this month's Hybrid Heating Call which is 4/11 at 2 PM EST, message me if you'd like to join our diverse group of policymakers, manufacturers, and practitioners.

@EckingtonPorch @ScottRobertsDC @ShawDC @CrispusAttucksP Hi---Please contact us at info@climateclub.us

here are notes from yesterday's @ShawDC #BloomingdaleDC Climate Club meeting held in @CrispusAttucksP on composting & sustainable travel facebook.com/groups/5798275… @mattxmal

@janrosenow IEA's World Energy Balances free extract should allow you to get what you need: iea.org/data-and-stati…

Looking for a nice graph showing global energy consumption split by sector (power, industry, buildings, transport). Any suggestions welcome!

the @ShawDC #BloomingdaleDC Climate Club meets this Saturday, 06-08-2024, 10am in @CrispusAttucksP topics: composting + summer travel facebook.com/events/1663932… @mattxmal

@rebeccajtiffany Yup---see this podcast about how Hertz bought Teslas and they crashed at 4x the rate of gas cars (due to acceleration and regenerative braking). bloomberg.com/news/audio/202…

the #DCHistCon is slated for this Thursday through Saturday at the @dcpl MLK Library static1.squarespace.com/static/612ed86… note that one of the panel moderators is none other than local writer & oral historian @shilpipaul 📙

@ZZZZach89 U, Florida, H, and Georgia are getting road diets/bus lanes soon. Can you see any improvement in the data from the projects on MLK and Minnesota? buspriority.ddot.dc.gov

Hope this was useful and please add any add any other resources in the comments!

Meanwhile, Meg Waltner of Energy 350 shared that the California draft Title 24 building code would only require heat pumps when the heating load is within 1 ton of the cooling load, and sizing the heat pump to meet that upon furnace failure

Up-front Cost: Pauravi Shah of Commonwealth Edison shared results of electrification projects in the Chicagoland area, finding $5-10k costs for hybrid heat pumps (equipment & install). drive.google.com/file/d/12bN2dD…
