"Mockery of Science!" DOE climate report contains โpervasive problems with misrepresentation and selective citation of the scientific literature, cherry-picking of data, and faulty or absent statistics." 85 climate experts say so in 434-page report. www.theguardian.com/us-news/2025... #energysky

On this Labor Day, thank you to US solar & wind workers, who are being attacked by the Department of Energy, Department of Interior, Department of Transportation & POTUS. "Trump said that his administration would not approve any wind or solar projects." newrepublic.com/article/1997... #energysky
I once laid out a couple of these pin-guides in a text editor, just monospaced text, two columns, then I would print one out, measure the %error from ideal 0.1" spacing, then re-print with a compensated % in the print scale dialog and voila.
Every time your electricity bill goes up for the next 10 years, it can be traced back to this Administrationโs actions. They are making solar and wind power illegal to build in the United States. They are artificially restricting supply while demand is going up.

๐๐กOf 133 GW of โhigh probabilityโ additions expected by 2028, 84% (90 GW solar, 23 GW wind) are renewables, with gas adding just 20 GW. Solar has led all new monthly capacity for 21 straight months. www.utilitydive.com/news/renewab...

sorry - AIUI is just old internet slang for "as I understand it". I guess keep an eye on this chart and see what happens. www.gridstatus.io/live/ercot?d...
Itโs a chart of what got built in 2024.
When the rate of new TWh being added from nuclear grows, it should start to show up on the chart. In the meantime there is no shortage of daytime combustion to neutralize.
Well, thereโs levels and there are trends. AIUI TX is adding PV even faster than CA is.
as long as it crowds out emissions from combustion, I love it
not quite make out the make/model of your magnifier light. can I ask what it is ?
Nobody can put hydro power on their roof and create direct energy independence and increased insulation from utility pricing changes. Same goes for coal, nuclear, natural gas
My POV, not as much for any one state/region to get to 100% RE year-round, but rather the rate at which quantities of daytime combustion can be neutralized. There is so much of the latter, I think we have several years of work to beat those down. TX starting down that path now
Seems you could model it like this: - get loan for a 1GW reactor - build a 500MW reactor and run it at full capacity - see if your power revenue covers the loan payment
The idea of adding 300GW nuclear in USA in 25 years.. if you can actually sustain 1GW deployed at the end of each year with Team-X.. need twelve such teams to get 300 in 25. Why I think that's not fast: global PV industry adds ~1GW in less than a week (counting TWh added, not nameplate).
Barakahโs net build rate was about 600MW per year? 5400MW added in nine years? Purely IIRC
Well when you see an example of an approach to nuclear that can deploy a GW per year say, I'd like to see where that is being done If it takes 5 years to build 1GW, only way to get to that pace is five teams concurrently building
I would think everyone who would like to see nuclear gaining share in new power builds, wants to see approaches that increase the number of GW added per year. Maybe there's a way to do it with large, maybe a way to do it with small. Who's figuring out how to build large reactors fast ?
Good morning with good news: Fossil fuels fell from 57.23% in June 2024 to 55.45% in June 2025 of global electricity. That 1.78-point fall in 12 months was ~50% more than average yearly fall of 1.15 points since 2019. FF may drop to ~46% by June 2030! Why? Surging wind & solar! #energysky

Wind cuts coal and gas burning, so petrostate politicos get very weird and wrong about it. It is often the lowest cost of new generation & high wind power states often have electricity rates at or below the national average. Wind makes oil & gas scream because it hurts them. #energysky
might not be a question of what is possible or has been possible in the past; might be a question about the rates at which these things occur i.e. see solar vs nuclear - both exist, both can be built, one is faster
why did mainframes keep existing once people could buy and build a home computer for a few hundred bucks? it takes a while.
Hereโs what @geomblog.bsky.social, @colesci.bsky.social, and I said about how the Administrationโs actions affect AI, innovation, and electricity (tl;dr because they are weirdly obsessed with stopping renewables, this will raise your electricity bills). techpolicy.press/trumps-ai-st... ๐๐ก

Disadvantaged communities are being hit hardest by the slowdown in clean energy manufacturing investments. They are seeing 47% of the projects slowing, compared to 30% in non-disadvantaged communities. This means that communities in need of opportunity are losing out.

on a circuit board scale, they're called decoupling caps :)
EV has a path to zero as grid gets cleaner. The gas cars are stuck, even if you somehow convinced everyone to drive a Prius. (25 MPG because it's the fleet average in USA) So my POV is simple: terminating demand for gasoline is much much faster than trying to hoover up CO2 with more trees.
On the third hand, trees burn.
Full grown tree consumes ~55 pounds of CO2 per year. 15 K miles at 25MPG is 600 gallons, 20 pounds CO2 per gallon. So 12000 pounds of CO2 out. 12000 / 55 is just under 220. ecotree.green/en/how-much-...
You need about 220 trees to keep up with the CO2 emissions from one average gas car driver. Displacing fuel burn with clean power (whether into an EV or by feeding the grid) is more effective than waiting for trees to save us - they can't keep up.

This is the other side of the coin re energy transition. Renewaables are the only sources capable of scaling rapidly & reliably enough to meet this demand increase. Trump's policies are nothing less than an act of social & economic sabotage. #EconSky #EnergySky #ClimateSky
Thatโs been true for a long time. Electrification&RE open an avenue to decouple commerce from combustion though. Example: CA growing its economy while shaving 40% off of natgas consumption for powerplants, in the last two years.

You might be wondering what happened to those claims from last year saying they made profits at $35. Those were lies, as I pointed out at the time.
Well we have things like SEER ratings for AC units so you know which ones can transport more heat vs. units of energy put in. From my POV a computer and a TV are nearly the same thing: the end product is virtually all waste heat. The value of the pixels provided is economics not physics?
I think it's what's left over after waste heat is subtracted out from primary energy. For something like a car, count the megajoules put in and the torque coming out. The torque is the useful energy, the MJ are the primary energy.
The Sun isn't going to dial back photon production if it thinks we are getting too good of a deal!
