Meanwhile, the economics are looking much better in China doing the same with renewables. But it's never really about what's more economic, is it?

Always wondered why restaurant food often seemed so disappointing across North America. I had suspected Sysco had something to do with it. Spot on!

It's so funny because the economics are clear as day. Collectively investing in the well-being and education of the next generation offers a great return on investment. But everyone is too busy investing into the latest pyramid scheme or bubble I suppose.

Today we were talking about busses, and my daughter worried that if less people buy cars, car factory workers will lose their jobs. I gave her a handwavy explanation that public transit generates jobs, but I don't actually know the labor economics of that. Anyone care to weigh in?

ExxonMobil's "What we do section" opens like this:

> Creating energy and sustainable solutions that improve quality of life and meet society’s evolving needs

Now that's a sentence I would love to see cited in a greenwashing lawsuit in Canada...

> edge closer to the 1.5 limit

Quite the understatement

Hegseth... Always impressed by their range. Managing to insult such a broad variety of people. Too bad I can't grow a good beard.

The U.S. Energy Secretary just said on stage at @nytimes.com Climate Forward event that “there are not oil and gas subsidies" in response to a good question from David Gelles. “It’s not a subsidized industry.” Uh. @oilchange.bsky.social @oilchangeus.bsky.social

Just saw my profile among the list of contributors to ggplot2 4.0.0 - that is a project I want to be affiliated with for sure. Pretty sure it's just for a ticket I opened. It was resolved within a record two days or something, too. The beauty of a well-running free and open-source software project.

Utilities really are not rising to the occasion, maybe energy demand from new data centers (AI anyone?) is to blame? Tons of new commitments to build gas power plants - 118 GW capacity planned by 2035. Only 29% of coal capacity poised to be retired by 2030.

I'm hearing lots about insurance companies absorbing meteorologists/recent grads. This industry is in a math war, and the math says things are getting much worse by the year. That's the real economics of climate catastrophy/adaptation were facing.

Unrelated, but my favorite German word is "vorauseilender Gehorsam" or anticipatory compliance. When you take action in expectation of orders that haven't even been given to you or even if you're not in the line of command, to avoid trouble or even opportunistically. For examples see German history.

My first academic article was on the dictatorship of Uzbekistan inventing a group called "Akromiya" that did not really exist but which they used to arrest anyone with whom they disagreed under the pretext of "terrorism". Just bringing this up for no reason whatsoever!

We/many countries could have easily adopted renewable energy 2/3/x times as fast, it's really sad. In many ways it feels like a half-assed attempt by a high school student who is mostly just whining. Drop in the bucket compared to the cost of new submarines, jet fighters, and other vanity projects.

Now there's a "doomism" of fatalistic acceptance that we're too late and it's just "too hard." We cannot afford that. It's the death throes of the largest industry in human history. Without the story of intentional obstruction, this piece is true but only as far as it goes. Sad. 4/4

Vaccine tourism (to Canada) was already a a thing during COVID, but this is on an other level. I'm having to wait two weeks for things to get sorted, and that's with a big asterisks, others will not be able to get the shot at all in Florida.

This is what we refer to as futurewashing in our green washing paper. Guess what you can claim anything you want about the future, how could anyone know. Without specific plans it has to be considered an empty promise. I didn't anticipate fossil fuel to fill that rhetorical void but makes sense.
ketanjoshi.co
okay this is getting silly now. An 11 gigawatt (!!!!!!!!!!) data centred, powered by fossil fuels but an obviously shallow, bad-faith empty promise to eventually build some nukes (only there to justify the new fossil fuelled power station they're building)

Fermi America files for IPO amid plans for 11GW data center campus in Texas
Developer of 11GW data center campus in Amarillo, Texas

September 08, 2025 By Zachary Skidmore  Comment
The company behind a gargantuan 11GW planned energy and data center campus in Amarillo, Texas, has filed for an initial public offering (IPO).

– Fermi America
Fermi America, a company co-founded by former US Energy Secretary Rick Perry, filed a Registration Statement on Form S-11 with the U.S. Securities and Exchange Commission related to the proposed IPO on Monday (8 September). Fermi intends to list its common stock on the Nasdaq Global Select Market under the symbol "FRMI."

The number of shares to be offered and the price range for the offering have yet to be determined.

According to Fermi, UBS Investment Bank, Cantor, and Mizuho have been selected as the joint lead book-running managers for the proposed offering. Macquarie Capital, Stifel, and Truist Securities will act as additional book-running managers.

Fermi is developing “Project Matador,” a planned 11GW hyperscale data center complex expected to span 18 million sq ft (1.67 million sqm). The project is being developed in partnership with the Texas Tech University System, with the campus set to be built on land at Texas Tech University. To power the campus, Fermi plans to utilize a range of on-site power sources, including natural gas, solar, wind, and nuclear energy. The company has already signed several deals to acquire the necessary power.

In July, the company acquired more than 600MW of natural gas generation assets across two deals. The acquired assets include nine natural gas turbines, which the company stated will support its goal of delivering 1GW of AI power at the site by 2026.

While natural gas will be the primary source of power in the short term, Fermi expects that in the long term, nuclear will become the primary supplier of energy to the campus.

The company has stated its intention to deploy four Westinghouse AP1000 reactors on-site. The AP1000 is an advanced Generation III+ Pressurized Water Reactor, with a capacity of between 1,100MWe to 1,117MWe. In an attempt to streamline the permitting process, Fermi has partnered with Westinghouse to finalize the Combined Operating License Application to deploy the reactors at the site.

However, concerns remain over whether Fermi will be able to deploy the reactors on time and within budget. The last set of AP1000 units installed in the US was at the Vogtle nuclear plant in 2023, coming in $17 billion over budget and more than seven years behind schedule.

Fermi has also signed two other agreements to support its nuclear ambit

Seems like car companies have normalized lying about your gas mileage so much that most consumers just take it for granted... That and plug-in hybrid SUVs are somehow a thing now...
