The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 15 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 0 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Baglino: Nuclear capital cost per kilowatt exceeds highly curtailed renewables
“When you look at the capital cost per kilowatt of nuclear with everything that is known today, it's much more expensive than even highly curtailed renewables.”
Baglino: Over 90% of Battery Precursor Plants Discharge Sulfates Into Waterways
“All the precursor, almost, I want to say all, over 90% of the precursor in the world is for battery cathodes is produced in facilities where the wastewater, the, like, sulfates and that are in the wastewater of that process kind of can just go directly into th…”
Baglino: Solid-state transformers are 50 to 100x more power dense
“So when we do this with a solid state transformer, we basically move the 60 hertz transformer to a hundred kilohertz transformer, And that makes it much smaller, like, 50 to a hundred times more power dense”
Baglino: Central inverters average 97.5% to 98% availability, leading solar plant underperformance
“Solar inverters are the largest source of underperformance on utility-scale solar plants. It's not the modules. You'd think it would be the modules, because there's so many of them, and they're out in the field, and you worry about hail, and you worry about wh…”
Baglino: High-voltage underground cables are comparable in size to fiber bundles
“Those fiber bundles are not that much smaller or different in size than what you would bury for a high voltage transmission line”
Baglino: Total annual global mining outweighs renewable buildout materials 10x
“One of the fun things that we put in the paper was a comparison of how much material humans just move out of the ground every year in total, and the amount of material required for just the This renewable energy economy, and it's actually like a factor of 10, …”
Baglino: Silicon carbide in Tesla inverters saved three miles of battery
“So silicon carbide went there, and then silicon carbide went into the drive inverter to make the drive inverter about one percent more efficient, which you're like, oh, that doesn't seem like a lot, but when you think about, you size the battery to give you, l…”
Baglino: Step-up transformer demand has surged over 250% since 2019
“In fact, I have some statistics here. You know, power transformers, these are generator transformers. Demand is up is over double since 2019. For generation step-up transformers it's up over 250%. Distribution transformers up over a hundred percent.”
Baglino: Electrification delivers nearly 3x boost in primary-to-end-use efficiency
“And so when you stack that all up and you replace that with a renewable electrified pathway, you can get almost a tripling of end use efficiency, well, sort of well to wheel or primary energy to end use efficiency boost, which actually is the, One of the first…”
Baglino: China and Netherlands lack dynamic EV charging despite prevalent chargers
“The interesting thing about both China and the Netherlands which are my most personal recent experiences with, you know, truly prevalent charging everywhere. They're really not doing this, even though they're charging everywhere.”
Baglino: Typical post-1970 home electrical panels rarely exceed 50 amps
“If you actually look at the typical home built after the seventies, you know, or maybe even the sixties in some cases, there's a 200 amp main panel that barely ever peaks above 50 amps.”
Baglino: Mechanical grid switches only last a few thousand actuations
“It actuates in hundreds of milliseconds and can actuate, you know, once every couple of minutes, and it's really not meant to actuate more than, like, a couple thousand times in its total lifetime.”
Baglino: Silicon carbide devices now operate up to 4.6 kV
“Silicon carbide 10 years ago was 600 volts or 1.2 kilovolts. You know, nowadays they're silicon carbide devices that are 2.3 KV capable or 4.6 KV capable.”
Baglino: Very few utility-scale transformers are manufactured in the US
“The transformers are generally made these days in, like, China, India, and Mexico. Very few of them are actually made in the US.”
Baglino: Average drivers only need to charge EVs every 3-4 days
“The average person driving, you know, less than 40 miles a day on average. In fact, like the 95th percentile trip is, is, is like 40 miles. You only really need to charge today's EVs with ranges of 200 to 300 miles once every Three days, four days”
