Nebraska utility NPPD selected four sites to possibly host new reactors. Those communities are expressing support. Article link in reply. Nuclear is now the most popular energy source in the rural communities where power generation facilities are built. Reasons including low land use, large numbers of high-paying, long lasting local jobs, and large contributions to the local tax base.

A way to see the amazing history of economic growth and declining poverty over the last two centuries.

2026 Power Trends Report from @NewYorkISO (on New York’s electric grid) shows: - risk of power outages is increasing - half of electricity still comes from fossil fuels - nuclear & hydro provide the vast *majority* of zero-emission electricity (i.e. NOT solar & wind) 🧵(1/12)
Power Trends 2026 is here. NYISO’s annual State of the Grid & Markets report explores how New York’s electric system is changing, and what it will take to maintain reliability through this period of unprecedented transition. Read the full report: nyiso.com/power-trends

Banning data centers in NY will accomplish the same thing as banning fracking in NY a decade ago: pushing lucrative industry to other states (& other countries). And New Yorkers will continue to use AI (with data centers in other places powered mostly by fossil fuels).
NY set to pass one-year pause on data centers - but tech leaders warn it's latest move to stifle economy trib.al/LpK7IWh

Energy <IS> the economy.
The S&P is 45% AI and 4% energy. The market is massively long the output. Massively short the input. AI runs on power. Every dollar flowing into Nvidia eventually flows into a gas turbine, a transformer, or a transmission line. The market has built a portfolio that ignores its own supply chain. I wrote about it, in my latest article, link in replies 👇

Governor Kathy Hochul (@GovKathyHochul) is fighting for action on climate change that works for all New Yorkers. As she wrote today in the Albany Times Union: "If climate policy becomes another burden, we will lose the public trust needed to sustain it."

The Usual Suspects. The fantastic four reunited for a great panel at the Chicago Energy Conference. Amazing to see the impact these nuclear superheroes have made over the last decade. Diablo Canyon, Byron, Dresden, Pickering plants all saved, State/Province and Federal policies changed in favour of nuclear. Never doubt that a small group of dedicated nerds can change the world. @nukebarbarian @MadiHilly @energybants

California’s only nuclear plant, Diablo Canyon, just won approval to stay open until 2045. It was scheduled to shut down in August 2025. Now it will keep delivering clean, reliable electricity for 4 million Californians for another 20 years. In 2022, I spoke at an American Nuclear Society event when Diablo Canyon’s closure seemed inevitable. The mood in the room was pure resignation. I asked the audience: “How did we convince ourselves it’s easier to shut down a safe, operating nuclear plant that employs thousands of people… and replace it with renewables plus batteries… than to simply keep it running?” Several people came up to me afterward and said they’d never thought about it that way. That’s what happens when a narrative takes over: we stop seeing the obvious truth right in front of us. But the days of insanity and delusion about the reality of our energy needs is over. Long live sanity! Long live Diablo Canyon!

Sex is good but have you tried saving California’s only nuclear plant and sticking it to the boomer anti-nuclear environmentalists?
Sex is good but have you tried having your country shutting down its last nuclear power plants in 30 mn?
Community note
Only 6% of the electricity produced by the nuclear plants going offline will be from renewable energy. The rest will be coal & gas. cnn.com/2023/04/15/eur…. Coal power produces ~100 times more radioactive waste than nuclear power. Therefore, Europe is about to become more - not less - radioactive. sciencefocus.com/science/do-coa…

🎉 Very excited to announce our latest product: ➡️ The Aalo Air. In a bid to increase social acceptance of nuclear energy, we have engineered an entirely new form-factor for nuclear. That's right: Aalo reactors, disguised as wind turbines. DETAILS BELOW 👇 💡 It might look just like a wind turbine, but it's actually an Aalo nuclear reactor, providing 9.9 MW of electrical output, and using 0.1 MW to inconspicuously spin the wind turbine. We expect to deploy millions of these all around the world, even in non-windy locations, in order to power the future of AI Data Centers, improve grid stability, and more. To achieve this optical camouflage, our engineering team had to solve a highly complex parasitic load optimization problem. To maintain a realistic rotation that precisely mimics local atmospheric conditions, even in a dead calm, our internal variable-frequency drive consumes exactly 100 kW. We calculate the required motor torque (τ) to overcome the aerodynamic drag of the stationary air against the composite blades. By dynamically modulating the angular velocity (ω) based on local weather APIs, neighbors will simply assume you are blessed with a remarkably consistent breeze. Beyond the aesthetic stealth, the form factor is surprisingly functional. The 120-meter tubular steel tower acts as an ideal natural-draft dry cooling system. The reactor's thermal gradient naturally drives ambient air upward through the tower, providing passive, pump-free decay heat removal without requiring local water sources. Furthermore, as the Aalo Air registers visually and dimensionally as a standard Class 3 Wind Energy System, we anticipate it will streamline traditional nuclear zoning hurdles. Unrelatedly, happy April Fools!

Here’s the link to the article: politico.com/newsletters/cal… If Paywalled, I pasted the text into my substack: ryanpickering.substack.com/p…
POLITICO just profiled me and a group of "hardcore" environmentalists in California working to modernize our state's nuclear moratorium. Here's my take and how Californians can help 1/7

In December 2021, Nuclear New York projected messages onto @NRDC’s office as part of the global hashtag#LightsInTheDark campaign. At the time, their longstanding opposition to nuclear energy had contributed to the premature closure of existing plants.
