Nuclear is inherently expensive even with zero regulations you have the full costs of a coal power plant + more expensive lifetime costs for fuel + extra costs associated with nuclear such as more and more highly educated workers. Meanwhile coal is dead because it’s already more expensive than the market is willing to accept. The only hope for nuclear is massive subsidies, deregulation on its own isn’t going to work.

How come Sweden as cheap nuclear power? The main reason electricity is kinda expensive in Sweden is because the EU forces is to export our cheap nuclear energy to Denmark and Germany.

Subsides, the cost to produce electricity and the cost charged for that energy end up very different.

Years ago, this very subject was an interview question at a national lab (at an undergrad level). The question was roughly: > the ends of windmill blades look a lot like a jet on radar. If you were assigned to this project, what would your approach be to avoiding false positives? This was in 2011/2012. I find it difficult to believe the problem is not solved.

Realistically, isn't it a known presence on radar? It's static - you can't just ignore signals from that area in space?

Even if it is a pretense, it is pretty obvious that this would allow ship-borne drones to use the wind farms as an effective screen. Putting radar platforms beyond the wind farms that are as capable as the existing land-based radars would be quite expensive in both capex and opex. Some of the existing land-based radars would likely need to be moved, ideally. No one was really thinking about this type of threat a deca…

The construction on some of these windmill farms started years ago. Before that permits & legal has been in the works for a long time. This surely included security clearances. The orange shrimp pulling the “national security” card now, on the same day as he also creates a new Greenland debacle, is very clearly simply an attempt to strong arm the danish govt into Greenland concessions (in turn simply to please his fr…

They were approved before the invasion of Ukraine and before our politicians could see how devestating drones can be. Just because the orange dictator did something does not mean it necessarily was wrong. Even a broken clock is right two times per day.

What the... It seems we crossed into the realm of intentionally doing damage. I'm reminded of threatening tariffs to successfully derail global carbon levy on ship emissions. Meanwhile China runs away with all the clean energy tech (solar, wind, batteries, etc, etc.) while we hold to fossil fuels to save less than 200,000 jobs.

He's been doing that since January.

> per-unit cost of nuclear power plants is extremely high Unless you are the US Navy. It probably helps that they churn out dozens of the same few cookie-cutter designs without needing permission from NIMBYs.

Honestly not a terrible idea. Just have your reactor on a huge barge and if it goes meltdown just drag it out into international waters and let the fish deal with it /s

An actual meltdown at sea would have the now-molten uranium come in contact with seawater, which would instantly flash to high-pressure steam, throwing the uranium into a cancer-causing cloud that the world has never yet seen.

This is absolutely a terrible idea about how to deal with a meltdown.

What? They've been intentionally doing damage for a long time. Pardoning criminals is one that comes to mind.

Pardoning criminals is one that comes to mind. Seriously, the pardons alone make this the most pro-crime administration in my lifetime. Probably ever.

At the same time as pardoning the Jan 6 insurrectionists, he's seeking multi-year felony convictions for... People standing in front of an ICE bus.[1]

I feel like the defense against drones is denser, sharper turbines.

This. Also, drones can be jammed pretty easily so making jamming stations on those platforms would be something too. The Brit’s have the right approach, just put radar on them so now you can see past them.

Jamming drones has gotten much harder. Ukraine and Russia have worked hard at defending against jamming.

That article is about emissions, not admixture. If you look at the source of that article, which they link to: https://carbonmonitor.org/variation First off we can now look at the full year instead of 6 months of data, its no longer US +4.2% and China -2.7%, its US +2.0% and China -2.3% China's 2025 YoY emissions decline is almost all due to a decline in industry, not power (1.8% of their 2.3% decline, in other words…

Their economy grew 3% this year and they cut emissions. https://rhg.com/research/chinas-economy-rightsizing-2025-loo... "economic slowdown" is an exaggeration.

A 3% GDP growth this year is a slowdown from 2024. Did you read this paper? I encourage you to at least read the abstract. It discusses whether "China's 2025 economic growth story turns on whether investment merely declined in the second half of the year or collapsed."

Occam's Razor: offshore wind requires a lot of rare earths for their magnets and whatnot. US military-industrial complex needs the little remaining global supply not under China's export controls.

Any electricity produced by turning generators will require rare earths. This includes, every current non-trivial electricity source with the exception of solar. Gas, oil, coal and nuclear all work by heating steam and running it through a turbine that turns a generator that makes electricity. For hydro, the falling water turns the turbine/generator.

So any source of electricity that may replace these wind turbines (other than solar) will require about the same amount of rare-earths. And lets face it, Trump is doing his best to hamstring solar as well. He has cancelled all solar subsidies and has hit solar with major tariffs.

I think Occams Razor would lead to a very different conclusion.
