Yes, turbine blades can introduce radar clutter and affect certain military systems; but this has been know since the 1990s and has been engineered around for decades.

China, the UK, Germany, and Denmark operate gigawatts of offshore wind in close proximity to military-grade and NATO air-defense radar without much issue...

There could be new developments in the problem. For example, small scale drones using these areas as entry points. Not to say that's that, but I think it's not impossible that something new is being taken under consideration.

There's actually some truth to the bird thing. Some of the first wind turbines in the 1980s had very short blades, 5-10 feet, and would spin at ~50rpm, sort of like a spinning baseball bat, ready to strike birds out of the air. Combined with not being very high off the ground, maybe 40 feet, birds would take off from the ground directly into the very fast spinning blades. Modern wind turbines neither look nor act like these early turbines, but that's where the data comes from. They only just retired those fast spinning, low to the ground turbines in like ~2017. Something like 80-95% of all bird strikes came from ~35 essentially prototype wind turbines, and virtually none come from modern, huge slow spinning turbines.

The real takeaway is when a big project can be paused entirely due to one presidents very specific / frivolous whims - we won’t be able to do big projects in the current order. We need a shift in the constitutional order where the whims of one person isnt fused with the bureaucracy

> We need a shift in the constitutional order where the whims of one person isnt fused with the bureaucracy

Correct me if I'm wrong, though there are already protections there. It's just president, senate, congress, SCOTUS all agree on this.

IMHO - most effective constitutional change would be to get rid of first past the post election system, electoral colleges, gerrymandering, etc. I think USA's two party system made it to the place where it is right now, seemingly on the verge of turning into one-party system.

softwaredoug 18 hours ago||
The US has had worse structural power imbalances in the past. It’s gotten over them (after a generation or more) by

- coalition shifts - every election, new groups going and out of each party

- demographic shifts - shrinking / growing / moving around of different groups

- external shock - war / depression / ?? changes incentives of governance (see Civil War, Great Depression)

- hegemons dilemma - the in power party over time goes through in fighting, over confidence, etc (see Republicans becoming corrupt in The Gilded Age)

Alternate constitutional order can mean a lot besides amendments - or even using Federal power. It can be about organizing economic power to reject illegitimacy. It can mean organizing the Democratic Party differently as more of a shadow set of social institutions that support people. It can mean leveraging state power, and building coalitions of blue states. Or other creative approaches to power.

How? Congress has given tremendous discretion to POTUS. This President is actually using it.

Congress assumed

- it had a legislative veto (any committee could override an agency)

- independent agencies existed.

So it gave broad authority with those assumed checks.

SCOTUS declared legislative veto unconstitutional in 1982. And administrative state is actively going away.

So POTUS can do a lot of damage using the law itself.

This is the new system. Dems need to use it too.

So we had this creeping loss of power to the president over time in the last 20 or 50 years, including investigations in the 1970s or dealing with Nixon. But Congress never really decided this in one big step, it just happened slowly by pushes from the heritage foundation and others. Congress can take back its power. There's a reason why the Republicans are trying to gerrymander the house so the Democrats don't get a majority. It wouldn't just fix it but it would be a start towards starting to block overreach

You can use different antenna designs for a more directional radar beam. Or tilt the beam upwards to steer it around obstacles.

robocat 1 day ago||
Perhaps if tip speed is X and radar installation is perpendicular to wind turbine, then an enemy can approach at speed X in the turbine's radar shadow. There would still be multiple pulses with timing differences but if there's a field of turbines then I'd guess there's enough interference/scatter to be a problem. Like using approaching from the sun causes problems for pilots.

The reflections from the turbines would pulse due to the blades so in theory their scatter could be cancelled out in processing?

I looked into this a little because I was curious. I guess the ostensible "national security" rationale (which clearly is not the only reason!) for this is that turbines severely degrade the utility of radar surveillance along the coastlines.

This is particularly relevant for low-altitude incursions and drones.

Now, other large governments (UK) have resolved this in several ways, including the deployment of additional radars on and within the turbine farms themselves.

So clearly this is politically motivated, and they're using what seems to be a real but solveable concern as a scapegoat.

Result first (kill anything not carbon-based), find rationale later.

Same applies to how this admin forced layoffs at the green energy (hydro + nuclear) behemoth BPA [1] (which was funded entirely by ratepayers, not the federal government) then claimed an energy emergency to keep open coal plants serving the same geographies, coal plants that were already uneconomical and planned for shut down (or re-tooling to gas in the case of TransAlta's plant in WA). [2] Oh and they already re-hired some of the laid off staff at BPA because they overcut.

There is no point in taking these arguments at face value. It's an excuse generated after-the-fact, and in service of one outcome - kill renewable energy.

US deploys nuclear energy at over $10/watt meanwhile solar and wind are deployed around $2/watt (for levelized cost of electricity) including battery storage which means they are deployed for roughly the same cost as natural gas (so, direct competitors).

Don't let comments like this fool you, nuclear is far from being competitive with natural gas. Even in countries like south korea that can deploy nuclear the cheapest it's still $3/watt roughly.

Good news? Net new solar and wind plants can come "online" in less than two years. Net new natural gas takes four years. Part of why 95% of new energy deployed last year were renewables in the US, not just the subsidies.

Nuclear is insane levels of expensive likely due to overregulation.

It is important for base load power and overnight power and should always be the backing of the grid frequency. Total loss of grid frequency is much more difficult to recover from with synthetic inertia.

A healthy grid should have all of the following - Nuclear base load that keeps the grid stable and pick up from low solar

- Gas plants for surge power and base load when nuclear/solar/wind cannot take up the slack

- Battery storage for surge/storage during off peak

- Solar for very low-cost cheap energy during peak usage hours

- Wind for other power source ie when the sun isnt shining as much

> overregulation.

Americans love to remove regulation to make things cheaper (and to enable capitalistic monopolies, but that's a different matter), then cry when people die (or worse).

Some things needs to be regulated, esp. if mistakes are costly to the planet and/or people on the said planet.

So yes, nuclear should be regulated, and even overregulated to keep it safe. We have seen what Boeing has become when it's effectively unregulated.

vablings 1 day ago|||
> We have seen what Boeing has become when it's effectively unregulated.

I think this is vastly overstated by the media. Boeing is still heavily regulated and has a pretty good safety record compared 20 or 30 years prior. The biggest disaster of recent times (MCAS) was because of the tight regulations around type certification and trying to avoid costs to carriers

> Some things need to be regulated, esp. if mistakes are costly to the planet and/or people on the said planet.

I absolutely agree. I am not for the removing ALL regulations from nuclear energy but there is a whole political servitude cycle that has taken place for a number of years to make nuclear "safer" when in actuality it has little to no influence on the technology and just adds burden and overhead especially in the new construction of a nuclear power plant

Nuclear is this big scary monster because its invisible death machine. Despite us being regularly exposed various levels of radiation in our lives most people are completely unaware of. Some people are terrified of dental x-rays but will happily jump on an intercontinental flight without any second guess.

I think arguing in the opposite of "you can never be too safe" is kind of like the whole double your bet every time you lose at the casino yes, its technically true but you need an infinite pool of chips for it to work.

Meaning they tried to skirt around the regulations, including regulatory capture by pushing self-certification because competition caught up to them while they spent money on buybacks instead of investing in R&D, perhaps even investing in absorbing some costs of certification of pilots into a new type they could develop into the future instead of relying on a design from 60 years ago.

Mismanagement is what created Boeing's issues, not regulation.

No, this is literally the opposite of what happened. They did not want all the operators to go through lengthy and expensive recertification processes as required by the FAA so they make the system as close as possible which likely cost them millions of dollars.

The issue was that pilots were not aware, they received very little training and knowledge on the subject when they should have had more (just not a new type cert)

Lost me right here, MCAS may have been motivated by losing type certification (as it should), but everything they did was not a result of regulations. Including upcharging to make the system actually redundant. Had they actually engineered the MCAS properly, they would have never gotten caught in the first place.

vablings 17 hours ago||
Yes but no. They wanted as many pilots to fly the new aircraft as possible without having to get them re-type certified which is pretty expensive. The issue is that pilots were completely unaware of the MCAS and when it malfunctioned there was not correct training in place because the system was "a hidden abstraction"

Clearly the system worked as intended because nobody had to be re-certified to fly the aircraft but being completely unaware of an additional control layer is dangerous and should have been known about by pilots, but Boeing kept it hidden.

There is room between under-regulation and over-regulation.

Given that we are experiencing high costs and other barriers to construction, we can do at least two things: reduce red tape where it makes sense or where the risk is acceptable to help lower costs, or the US government can, through a variety of mechanisms ranging from basic research funding to direct subsidies, spend taxpayer money to try and alleviate costs.

Given that we supposedly (and I agree) need to build nuclear reactors to help power our country and given that we aren’t building them, we can optionally use both levers to encourage construction. There seems to be this mind virus that has infected many people on the internet that seem to think that regulations are a moral good, and so having more of them must be more good.

This is not accurate.

Regulations are simply a tool we can wield to achieve desired outcomes within various risk and need-based calculations. More regulations can be good, for example we should ban highway billboards- that would be a good regulation. Or we can eliminate regulations - allow businesses to build more housing using pre-approved designs that meet existing zoning code. Neither is good or bad, except in that it helps to achieve some aim that society has.

The regulation or lack there of, of nuclear energy in the United States has absolutely nothing to do with Boeing airlines screwing up some plane designs. Drawing a conclusion that nuclear energy must be regulated (it is) or over-regulated (it probably is or else we would build more), because of a belief that Boeing airliners weren’t regulated enough is, to put it lightly, nonsense, and you are mistakenly using the application of some regulation or lack of causing some bad things to happen, to imply that more regulation in another area would mean good things happen through this framework of regulation == good.

And further, if you’re going to suggest that Boeing is effectively unregulated, which is untrue in practice and in principal, then I’d argue that was for the best given that it is a hugely successful company that employs tens of thousands of people and hundreds of millions have flown and continue to fly on their airlines every single day safely and without incident.

> In the entire history of civil nuclear power "unknown parties stole the radioisotopes" has never happened.

This reads a bit like "why do we need a QA department when we don't have any bugs"?

The reason nobody stole the stuff from reactors is because everyone has, by international law and also nonbinding recommendations, security and armed guards making sure they don't. These are not free.

The Goiânia accident was stupidity, not malice, so you can't predict how many people would die if it was done maliciously from how many were killed. My understanding is what keeps people (relatively) safe from this type of attack at the moment, is the public deployment of radiation sensors since 9/11, which we know about because of people with radioisotopes in them for medical reasons getting caught by them. These are not free.

The Chrenobyl reactors were housed in what’s "best described as a shed" because that was cheap. Same for all of the other design issues with those reactors: it made them cheap.

The biggest issues people usually have with any construction work is dealing with the city/county because they throw up the most roadblocks and you do not have the freedom to choose, in the case that there is no free market available the regulation must be good, cheap and efficient, a bit off topic but alas

ImPostingOnHN 14 hours ago||
> If you need plumbing work usually you have to pull permits from the city

Most work you'd hire a plumber for does not require any sort of permit. Fix a leak? Replace a toilet? Install a water hammer arrestor? Unclog a toilet? Hydrojet a sewer line? etc. None of those have ever required a single permit for me. A recent $450 quote to install another shutoff valve was about 95% labor, 5% parts, 0% bureaucracy.

In fact, I would be surprised if there was a single location in the US where permits constituted "a large majority of the costs" of plumbing work done in that location. I honestly don't know what you're talking about there. Maybe you could share such a location?

Indeed, the cost of most construction work is not dominated by any sort of bureaucracy or government-mandated paperwork, but by materials and people doing the work. If I bought a new house for $1M, regulation did not constitute $500,000 of it.

> The biggest issues people usually have with any construction work is dealing with the city/county because they throw up the most roadblocks and you do not have the freedom to choose

This is simply not the case. Maybe you're talking about the issues you personally have. The biggest issue people usually have with construction is the cost, and the biggest part of the cost is the labor and materials, because you live in a high-COL country. The current inflation and tariffs we're seeing don't help. I guess if we want to bring costs down by cutting regulation, the overwhelming tariffs (aka very expensive regulations) would be a good first target, and that would help address inflation, too – bonus cost savings!

> I am against overwhelming bureaucracy

So is everyone else, but is hiring a plumber expensive because of "overwhelming bureaucracy"? No, it's because it costs money to pay the people who do the work.

Nuclear is expensive because of the large amount of high-skill labor, including welding, that's required. For less economically advanced countries, that labor is cheap. For more economically advanced countries, that labor becomes more expensive. Regulation is a red-herring being pushed as an excuse, mostly by startups that are desperate to get the next round of funding, because it plays very well to the investor class, but it's not based in reality. I ask about this all the time and even if there are some half-baked critiques of things like ALARA, nobody has a path to actually making the Nth build of a reactor cheaper from changing regulations.

Even France, which is known for having far lower construction costs than the US on big projects, and for being very good at building out their nuclear fleet in the past, is at ~$12/W with their newest round of 6 reactors. And that's before they have even started construction:

https://www.reuters.com/business/energy/frances-edf-estimate...

This is roughly the cost of the latest US nuclear reactor at Vogtle, which is viewed as unrealistically expensive energy.

And even the most optimistic plans for reducing the cost of nuclear from the Liftoff report in 2023 from DOE doesn't place regulations as having much of a role in lowering costs:

https://gain.inl.gov/content/uploads/4/2024/11/DOE-Advanced-...

There's significant political interest in having regulation be the reason that nuclear is expensive, but I find almost zero people in the nuclear industry that are able to articulate where regulations increase the cost of builds or whether there's anything that could or should be changed about the regulations.

Retric 1 day ago|||
I don’t think nuclear waste is a huge deal, but it does increase fuel costs in a very meaningful way. The classic uranium is cheap therefore nuclear’s fuel is cheap is a tiny fraction of the story. Refueling generally means weeks of downtime, you can’t safely operate at extreme temperatures for maximum efficiency, you need enrichment, and fuel rods, and even with multiple trips through the reactor core a significant amount of fuel isn’t burned or economically useful, and when your done you also need processes do deal with highly radioactive material + the costs of dry casks, and then transport them offsite and then down into some tunnels.

Add all that stuff up and fuel is a major expense. Granted that downtime depends on the design, and is also used to do other maintenance tasks but without refueling you’d end up with different tradeoffs.

I disagree. building big infrastructure projects always scales well. As stated by the project managers at Hinkley Point C (the most expensive nuclear reactor ever) they estimate that build times and cost will be significantly reduced for the second reactor due to the knowledge and expertise baked into the workforce. Frances nuclear revolution during the 1972 oil crisis also shows the same thing with construction cost getting lower the more reactors built.

Even at military contracting prices, estimates put them at $100-200M each IIRC. That's not terrible.

The highly enriched fuel is used because it simplifies the design and maintenance. It eliminates all the machinery you'd need to support things like operational refueling of the reactor. Old designs still needed to be rebuilt every 25 years but the new ones are sealed systems that are never supposed to be cracked open over their design life.

This comment is also misleading. First, $/watt is not how levelized cost of electricity is measured, you need to use $/watt-hour (or more commonly, $/MWh) over the lifetime of the project. By definition, levelized cost of electricity does not include storage.

The cost is also affected by the percent of energy coming from wind+solar+batteries vs. from natural gas. Wind+solar+batteries are cheap when they are used to supplement natural gas. If they were supplying 95% of generation (Levelized Full System Cost of Electricity 95%, LFSCOE-95), then the price of wind+solar+batteries would be $97/MWh compared to $37/MWh for gas, and $96/MWh for nuclear. For LFSCOE-100, the price of wind+solar+batteries increases to $225/MWh, compared to $122/MWh for nuclear and $40/MWh for natural gas.

Source: https://en.wikipedia.org/wiki/Cost_of_electricity_by_source#...

So yes, natural gas is much cheaper than nuclear. But that doesn't mean that nuclear shouldn't play a large role going forward. The moral of the story is that the price of energy is complicated. It's likely that a combination of nuclear, wind, solar, and battery backup would be the best option in terms of price and carbon emissions.

I didn't disagree that there is price parity for the levelized cost. There is still not price parity for levelized full system cost. If we used wind and solar for 95-100% of generation, the price would be much higher.

My point is not that we can or should replace wind and solar with nuclear. It's that it is far cheaper to use a combination of nuclear, wind, and solar than it is to use 100% wind and solar.

laurencerowe 1 day ago|||
I think it’s quite conceivable that nuclear would be cheaper for a 100% carbon free grid.

But I don’t understand how the combination of nuclear, wind and solar would be low cost. Wouldn’t you effectively have to build out enough nuclear to cover still cloudy days at which point your wind and solar is not very useful? That sounds expensive.

I suspect we won’t end up building much nuclear because we will already have built out so much wind and solar. Nuclear is a poor fit for filling gaps in generation by intermittent renewables because fuel costs are negligible so it costs the same whether you run at 50% or 100% of rated output.

To eliminate carbon emissions entirely we will need some green hydrogen for turning into aviation fuel and as chemical feedstocks. Perhaps the gas backup will eventually burn that.

belorn 1 day ago||
Green hydrogen is prohibitively expensive and are still way more expensive than using fossil fuels to create hydrogen (called black hydrogen). Burning green hydrogen for electricity when we have yet to make green steel economical viable is not a good idea. Nuclear is still a magnitude cheaper than that.

Green hydrogen has to first prove itself that it can become economical viable. One of the biggest test trials for that is the Swedish initiative, and that one is mostly paid through subsidies and grants. Sadly it isn't looking very great even if the government did decide to continue sending more billions into the project.

laurencerowe 1 day ago||
I completely agree that green hydrogen is prohibitively expensive at the moment and it currently makes no sense to burn it for electricity generation. But it will likely be necessary in the future if we are to decarbonise aviation fuel, steel making, fertiliser production, etc. What matters at the end of the day is reducing total carbon emissions for the whole economy.

Intermittent renewables and batteries will get us to 80% carbon free electricity generation for more quickly and cheaply than nuclear. While nuclear might make sense in the very narrow use case of 100% carbon free electricity generation, given we also need to decarbonise non-electrical emitters, it will probably reduce more carbon emissions per dollar spent to instead spend that money on even more cheap intermittent renewable generation capacity and use the excess to generate hydrogen. At the point hydrogen based fuels may make sense to use as a buffer for intermittent electricity generation.

gardncl 1 day ago|||
Agreed. I misunderstood your comment and got too hot-headed. Sorry about that.

Yes, the 95% renewables is the number we should be shooting for not 100% as that causes battery backup price to explode.

I have been pro-nuclear for a long time, to disappointing results naturally. So, with how well renewables are doing I've really just jumped on this train and seen nuclear as more of a distraction from the critical next 10-20 years given how long it takes to come online.

At the end of the day the grid is only about 30% of the emissions problem (depending where you look).

fasterik 1 day ago||
I may have misinterpreted your original post as saying we should be going full renewables. I think we're basically in agreement about prices. We might just disagree about the percent of energy that should come from nuclear.

I don't see nuclear as a distraction, I see it as a piece of the puzzle. We will always need a source of reliable, uninterrupted power. Whether that comes from natural gas, nuclear, geothermal, hydro, etc. depends on geographical considerations and what tradeoffs we are willing to make in terms of cost and carbon emissions. I'm still optimistic that small modular reactors are going to see success in the coming decades.

gardncl 1 day ago|||
Yeah, my opinion on how much should come from nuclear is that current levels (~20%) are enough to fill the rest in with renewables.

I'd love to be France (~50%) but there is so much pushback against the technology due to accidents that happened decades ago with generation II plants (chernobyl + three mile island). We're now building tech for gen III+ plants and there is just almost no appetite to build them, we finished the vogles and now are completely pivoting to SMRs, which is fine.

SMR is probably what makes the most sense even if they're less efficient because until now the nuclear plants have not been very standardized which increases costs.

Why do I think nuclear is a distraction? Because I don't think it's a like-for-like replacement of fossil fuels and this admin knows that. They're willing to invest because it won't disrupt their biggest donors. The time horizon on nuclear is long, and there is a future (I hope) where we have nuclear plants hooked up to carbon capture technology and we pull these gasses out of the atmosphere. But until then what is the cheapest and most efficient path between current emissions and a massive cut in them? Renewables and battery tech (that's currently undergoing very dramatic cost reductions!).

Thanks for that.

A cost model has a lot of independent variables. It can be a weird function of the quantity you want of each technology. Not everything gets cheaper at scale. And you need to be able to manage time-varying demand.

For easy example: a few solar or wind farms cost $X to bring up, but to go large scale you need to also store or transmit the energy, plus keep fallback options. That makes 95% or 100% reliance prohibitive.

There is also the speed of powering on/off. Gas combined cycle turbines are fastest to come online/go offline, followed by hydroelectric (if you have it). Coal and nuclear are at the slow end. You need to have the ability to match total sources and loads at any time.

Just some intuition why total cost is a complex function.

ViewTrick1002 1 day ago|||
First. $120/MWh for new built nuclear power is cheaper than any modern western reactors. Real costs are ~180-220/MWh when running at 100% 24/7 all year around. As based on Vogtle, FV3, HPC, proposed EPR2s, proposed Polish reactors etc.

The problem with these ”system costs” analyses is that they don’t capture the direct physical incentive structure of our grids.

Why should someone with rooftop solar and a home battery buy $180-220/MWh when they have their own electricity available?

Why should they not sell their excess to the grid cheaper than said nuclear power? It is zero marginal cost after all.

You can call it tragedy of the commons but new built nuclear power simply is unfit for our modern grids.

We need firming for near emergency reserves coming from production with the cheapest possible CAPEX without an outrageous OPEX.

Likely gas turbines running on carbon neutral fuels. But only if we determine that they are needed in the 2030s.

Yes, but you have to pay for a line you don't plan to use much, so its capital costs should be attributed to the generation method requiring it. Which is fine, but not including it is dishonest about the true costs.

I think if you designed and built it with the idea in mind that you're building your renewables in the sunny/windy centre/south of the US to be transported to a these places all year round it's a better idea than it being a backup.

Exactly. And you need closer to 100x for some locations (Germany) for the solar to be reliable enough.

Solar is _very_ cheap when you don't care about reliability, and impossible otherwise. Wind is a bit more nuanced, but in general has a similar story.

Those costs with storage are if you want 100% power from solar which is not reality. US alone gets 20% of power from nuclear today, we’re not going around tearing down the base load and adding solar. We’re keeping base load and adding renewables, which include wind.

Also if renewables are so dumb and are so problematic why were they 95% of new power generation installed in the US last year?

Solar is not dumb in some parts of the US, like California or Nevada. It's dumb in the Pacific Northwest or Minnesota.

On the other hand, offshore wind is the _only_ form of renewable energy that is at least a bit reliable due to the inherent diurnal wind patterns near the shores.

This administration won't last long enough to see any of these nuclear ambitions to any sort of success (its takes at least a decade to build nuclear generators in the developed world). Words are cheap, and regime change is coming. Solar and battery storage is already the cheapest form of generation in most of the world, and will only continue to decline in price, while the US will continue to face system and labor challenges precluding the large scale construction of commercial nuclear. The US currently doesn't have enough labor to build residential construction and naval vessels, so it will be interesting to see where they attempt to source this labor from (assuming the usual labor pipeline challenges where it takes up to half a decade to turn a human into a skilled tradesperson from an apprentice or other form of beginner).

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.

This reply doesn't address any core point.

When these wind farms were permitted many years ago, shipborne drones were not part of the threat matrix. It was considered purely hypothetical even a decade ago because it was not an imminent capability for any country even though e.g. the US DoD had studied it. In the last few years shipborne drones have emerged very quickly as a substantial practical threat, largely due to the Russia/Ukraine war. Governments around the world are struggling to adapt to this new reality because none of their naval systems are designed under this assumption.

Whether or not this is convenient for Trump doesn't take away from the reality of the security implications.

Msurrow 1 day ago||
Yes, it does.

First of all: occam's razor. Political theatrics seems simpler than the US defence/intelligence forces sudenly realizing that drones can be launched from ships. Esp. with the timing involved.

Second: Established/traditional radar systems cannot spot drones. Take it from someone living in a country that recently had its airspace violated by (assumingly) Russian drones, affecting national infrastructure. It was considered an attack at the time. I don’t think thats the word we use any more, for political reasons.

Third: Trump already shut down one of these windmill farms once this year. Until the danish company building the park sued and got the courts word that the shutdown was illegal, and resumed construction. The current shutdown has much larger impact for many multi-national companies. Usually there is a political process expected between allied countries before such a drastisc move. We havnt seen that ie no attempt to solve a concrete (security) issue before punching the red button ie probably because there was no motivation for a solution ie the security issue was probably not an actual issue)

Fourth: Earlier this week the danish intelligence services released a new security assesment of USA (that takes Trumps behaviour on the international scene into account). That probably hurt the little mans ego, and now we see a retaliation. This provides yet another motivation for Trumps action, besides factual, real security concerns.

Looking at this purely from the security aspect is naive, and fails to consider the context of the real world.

Bringing up a map of wind power deployments tells the story; what you will see is a hot vertical strip in the center of the US. That is where it actually makes sense to deploy windmills, and people will continue to put them there even if subsidies end. It makes sense for the area, the amount of wind, the serviceability of the deployments, etc.

Off shore has always been politically contentious because it's much more dependent on subsidies, it's a battle for/against rent-seeking. One party is in favor of this particular kind of rent-seeking and the other party isn't (they will be in favor of a different kind, no doubt). The subsidies are necessary for these deployments to make financial sense, and if they went away, then it would just be a bad place to put a windmill.

There is no national security issue, there is no real case for energy infrastructure either. This use case needs government money to make sense, and is therefore sensitive to political fluctuations.

alphazard 1 day ago||
> Why do you say it's rent seeking?

Because that's what economists call it when you get something for nothing, as is the case with any subsidy. I'm not going to argue this point; interested readers can look up how these energy projects are financed. Windmills that are privately funded, including debt and risk show you where it actually makes sense to put a windmill.

> Offshore wind is efficient, turbine blades can safely be much larger giving 3x the output, turbine arrays have unobstructed space giving twice the capacity factor. It's more efficient than onshore.

Not going to argue with any of this, although you left out maintenance costs, and larger blades means more value at risk. I'm not convinced that your efficiency calculation is measured in dollars and not windmill hours.

I would caution any engineer types reading from pressing their nose too close to the details of a particular energy technology. Instead, it's better to focus on the business plan or economic shadow that a particular energy project leaves. Dollars go in and energy comes out. A bunch of money has to go in up front, then trickles of money slowly over time, and occasionally spikes of money have to go in randomly. In exchange there is a modest, predictable flow of money out, which eventually is larger than all the in-flows in the bull case. The question to ask is: how much in and out of dollars and of Joules at each point in time? How does that compare to hamsters on wheels, people on bicycles, and lighting things on fire?

It is more difficult than you may be assuming. How do you know the hits are false? These "hits" are collections of samples at points in time, not continuous tracks. The "tracks" are reconstructed by making inferences from the samples.

Determining whether any pair of sequential samples represents the same entity or two unrelated entities is an extremely difficult inference problem with no closed or general solution. If there is too much clutter, it becomes almost unresolvable. Aliasing will create a lot of false tracks.

History has shown that any heuristic you use to filter the clutter will be used by your adversary as an objective function to hide from your sensors once they know you are using it (e.g. doppler radar "notching").

For this reason the inference algorithms are classified but they will degrade rapidly with sufficient clutter no matter how clever. It is a limitation of the underlying mathematics.
