Climate dad, Canadian energy policy nerd. I post about energy technologies and how we can use them to stop climate change. Views my own. #energysky
How much did it cost to insulate?
26.08.2025 22:20 β π 1 π 0 π¬ 1 π 0Of course the fossil fuel sector has slowed the transition, but climate advocacy has also failed by any measure. Digging into old strategies won't work. Time for a rethink.

No. The climate community needs to stop blaming other people for its own failures.

Outbreaks of measles here - enough that they moved up my 2 year old's second jab by 2+ years π¬ (usually 4-6 years).
I'm not sure this is ag runoff, article indicates it goes into the waste water system.
Pretty concerning pattern of violations at this facility regardless (of which this video seems to be one), seems like it's time to tighten up AD regs.
The trouble is those loads show up all at once and have a terrible load factor the rest of the time. EVs and electric water tanks end up putting much less pressure on rates so long as those peaks occur at off peak times, that won't be possible for ASHPs w/o storage, which cost more $$$.
26.07.2025 10:10 β π 3 π 0 π¬ 0 π 0In my view the solution to this is better heat pump design and technology: sizing closer to load to maximize that peak COP, while moving to lower turndown ratios and R290.
That said, hybrids also very much are deserving of a lower rate and could help lower gas usage, but slows full electrification.
Not aware of specific modeling on it though, aside from modelling for DSM program (which I did a bit of back in the day). When you look at it like that with a reasonable $/kW-year assumptions it's hard to escape how much pressure heat pumps put on the grid/rates.

This is the best heat pump explainer video I've ever seen!
Great work Drew Tozer!

It is a fact that averages can misrepresent the circumstances of outliers, that's how they work. I'm responding directly to the evidence you provided. It's already a narrow margin, and it relies on various optimistic assumptions (I focussed on one key one mileage.)
Happy to debate further.
I am pretty mad at Elon for saying my country isn't real...and there's a lot of junk to sift through... It's tempting though

19.07.2025 21:40 β π 0 π 0 π¬ 1 π 0Thanks. This is really it, it's not a huge deal, it's just less fun and that sucks. The original post just kind of exemplified why I've stopped posting as much.
There's still lots of good stuff here to read and engage on, and less junk to sift through than on X.
Yes, that's why my interest is on net zero compatible natural gas use, not using it as a bridging fuel.

19.07.2025 17:23 β π 1 π 0 π¬ 0 π 0It was someone celebrating the fact an article about AI had worse engagement here than on X. "That's what a tight ship looks like" was the quote. Actively celebrating the fact this platform's culture drowned out discussion with hostility towards the idea being presented.
19.07.2025 17:21 β π 0 π 0 π¬ 1 π 0So no, you cannot assume that based on a simple calculation of averages (not to mention the other potential issues I pointed to with that analysis).
19.07.2025 17:19 β π 0 π 0 π¬ 1 π 0Averages are skewed by outliers, and there are *a lot* of outlier drivers on both ends of that spectrum.
Very high mileage cars often serve rural or just in time contexts which EVs still don't cut it for in many cases.
Yes for sure.
