The title is a bit non descript, so the blog post is exploring

> a 15K-array, 2.9M-panel dataset of utility and commercial-grade solar farms across the lower 48 states plus the District of Columbia. This dataset was constructed by a team of researchers including alumni from NOAA, NASA and the USGS.

jibal•2h ago
This will change under the policies of the current U.S. administration.
cactusplant7374•2h ago
I am still receiving advertisements from solar companies that want to put panels on farm land. They pay around $3-$4k an acre
binarymax•2h ago
Per month or year? And what region?
tecleandor•2h ago
Like monthly? Yearly?
ben_w•1h ago
I'm not the person you're replying to, but if I read the following link correctly, the USA average price to purchase is only $5.5k/acre, and any part of the US cheaper than or including the average price in Nebraska (ranked 17th at $3,884/acre) could well be trading food farmland for solar farm land at that price:

https://acretrader.com/resources/farmland-values/farmland-pr...

Zigurd•1h ago
In Nebraska, you're talking about food for cattle. The profit per acre is low and so the price is low.
ben_w•45m ago
1. The Nebraska price is the 17th highest on that list. Nevada and Montana are both below $1k/acre. I've seen Nevada in person, I can guess why the small amount of possibly-arable land I saw there might be cheap, never been to Montana but the Google street view photos told me the same story.

2. If the profit per acre is low, surely this just means they don't have a better use for the land?

3. Even if you assume they're all idiots who could make more profit if they thought harder about better uses for their land, I'm not clear why the reason for the land being what it is, is supposed to matter?

tecleandor•11m ago
Well thanks. Now I reviewed what I had in mind for the size of an acre, and it's way smaller than I though (I don't know why I was thinking it was way bigger than an hectare). Also, I always forget the size differences of unused land between continental Europe and the US. :D
dgacmu•1h ago
This is for a 20 or 30 year lease. One time payment. 4k is on the high side.
hwillis•1h ago
Pretty unlikely. Solar is built on cheap land with low demand, and if the land isn't sold then the power is free so why wouldn't you sell it? No matter how high the taxes are, free money is free money. Aside from making it totally illegal it is very hard to reduce the incentive to sell power.

On top of that the subsidies for solar installations are mostly frontloaded, since the costs are frontloaded. Annual tax breaks are transferrable, so they get sold at the beginning of the project to offset investment cost, lowering interest payments. Even removing tax breaks would not make existing installations less profitable.

BolexNOLA•1h ago
You are right it makes sense but that hasn’t stopped them from gutting all sorts of sensible programs both energy-related and otherwise regardless of the stage of investment/development. Have we forgotten about Musk and his mob already?

This administration is openly touting “beautiful clean coal” (doesn’t exist) for powering servers. Renewables are yet another front where people are divided based on politics. It has little to do with efficacy or practicality. I still have family members convinced that offshore wind power is mass-killing whales because of Carlson.

joshstrange•22m ago
> I still have family members convinced that offshore wind power is mass-killing whales because of Carlson

And if they are anything like the people I've talked to, they never once cared about whales (or any sea life) before this. Same with the "wind turbines kills birds" or even "trans women are ruining women's sports". Ahh yes, a whole list of things you've never cared about, made fun of, or derided in the past but now suddenly care about because of some talking head. It's exhausting.

nkoren•45m ago
Yes, it would be absolutely irrational and indefensible to block people from building solar farms where there is a straightforward commercial case for doing so. Unfortunately, "irrational and indefensible" is exactly what this administration is: https://www.theguardian.com/us-news/2025/oct/10/trump-offici...
ishtanbul•31m ago
I work in the industry. Removing the tax breaks is having a material impact because we look at after tax cash flow. Next year installations are going to reduce meaningfully.
FrustratedMonky•20m ago
The articles about Solar cost reaching parity with Fossil. Is that before or after taxes?
bluGill•7m ago
Taxes are far too complex to figure that our. In the case of other there are a lot of different players and most do things other than oil and so it isn't possible to figure out what tax/subsidy is from oil.
UltraSane•1h ago
Federal funding for solar farms will stop but private funding will continue because solar electricity is the the cheapest source right now.
ben_w•1h ago
Unless it gets outlawed, which I suspect is something Trump might do or attempt as part of his campaign in favour of fossil fuels and/or to own the libs/China.

I'm also not clear how cheaply the US could make its own PV in the event of arbitrary trade war (let alone hot war) between the USA and China.

(The good news there is that even in such a situation, everyone else in the world can continue to electrify with the panels, inverters, and batteries that the USA doesn't buy, but the linked article obviously isn't about that).

criley2•31m ago
It's more than just funding. There's a lot of regulatory hurdles and desire to use federal lands that will also be killed.

https://www.theguardian.com/us-news/2025/oct/10/trump-offici...

>The following month, the president said his administration would not approve solar or wind power projects. “We will not approve wind or farmer destroying Solar,” he posted on Truth Social. “The days of stupidity are over in the USA!!!”

Realisitically, solar is dead in America and China is the undisputed worlds #1 solar superpower. The US might hook up a few little projects here or there, but functionally the US is in full retreat on solar, cedeing the industry and technology to China.

UltraSane•25m ago
The federal government doesn't have to approve solar farms built on private land. Solar is far from dead in the US and there is tons of private land solar farms can and will be built on.
criley2•18m ago
Most the best land for solar farms in the west half of the US is controlled by the federal government. https://upload.wikimedia.org/wikipedia/commons/thumb/1/1f/Ma...

For example, there basically will not be large scale solar in Nevada, Utah, Arizona, etc under this administration. You know, some of the highest value spots.

bluGill•5m ago
Nevada, Utah and Arizona are all low population states with little power demand. While power can be shipped that needs power lines and other complexity. There is a lot of solar potential there, but the lack of demand means they are not highest value.

My experience has been that people living next to newly constructed solar farms are unhappy about living next to a solar farm. It is also my experience that this is a fringe opinion because a very low percentage of people live next to solar farms.
squigz•1h ago
"My experience is that people whose homes have burned down are unhappy that their homes burned down. It is also my experience that this is a fringe opinion"

Like what?

nemomarx•1h ago
Is a solar farm being built nearby as bad as your house burning down? I didn't think the property value would change that drastically...
squigz•1h ago
No, but I was trying to illustrate the absurdity of dismissing these as 'fringe' opinions, simply because they only apply to the segment of the population that are actually going through it.
trimethylpurine•1h ago
Seeing them feels dystopian. I actually don't think that opinion is so fringe. There were lots of environmental protesters when the solar farm near us went up. The valley was rich in low shrubs and wildlife, and even some forest was leveled. A multi billion dollar energy company destroyed it to pick up their share of the free government funding while powering less than 2% of homes.

Sure, it's better than a gas refinery or some other things you could find yourself living next to. But let's not ignore what's bad about our current solutions.

Seeing a big solar farm out in the desert does feel cyverpunk’esque/dystopian in a way. I suppose it’s the juxtaposition of new technology with the harsh natural beauty of a desert.
bfkwlfkjf•1h ago
Would you like to share with us what it is they say makes them unhappy about it specifically?
ourmandave•1h ago
I had to google it and apparently the complaints are:

Ruin the view,

Lower property values,

Habitat destruction,

Noise from inverter fans

UltraSane•1h ago
I can understand not wanting to live close to wind turbines but I don't understand the issue with living next to a solar farm since the panels just sit there silently.
AlfeG•1h ago
Because they are not silent. Or sometimes are not. Inverters do have quite large fans.
BolexNOLA•1h ago
Compared to literally every other way of generating power, they are relatively silent and unobtrusive. They also don’t poison the air around them which is pretty neat.
mauvehaus•7m ago
Yes, but the relevant comparison for the residents isn't to a coal plant, it's to the undeveloped field that the solar arrays replaced.

Depending upon their other priorities, they may be upset about the loss of hunting access as well. Understandably, people putting up solar arrays don't want people firing guns in the middle of their arrays.

marcusb•9m ago
This is a very frivolous argument against solar farms given the amount of noise and other pollution emanating from regular farms.

Farm-scale irrigation is not silent.

Crop Dusters are not silent.

Combines and other tractors are not silent.

Burning fields are both not silent and release a tremendous amount of sooty smoke that spreads far beyond the boundaries of a farm.

Farms make a lot of noise.

alexdns•1h ago
Well its not silent those panels go into MPPTs that produce noise when high amps are flowing through them to charge batteries if they don't direct export , if they direct export then there is noise from inverters to convert DC->AC
Geezus_42•55m ago
But is it honestly enough to notice if you live half a mile a way? Couldn't they just put up sound damping like the oil rigs do?
ourmandave•1h ago
Maybe the guy who cleans them complains loudly, or the squeak of his 4' squeegee is annoying.

Lots of people dislike change. Neophobia is a thing, and it's not particularly uncommon.

The good news is, they'll rapidly adapt to each new solar farm; the bad news is, they'll forget about all the ones they're used to by the time comes to expand — I've seen anecdotes of the same thing happening with power lines, where people were upset that some proposed new ones would ruin the view, the person proposing them said they wouldn't be any different from the current ones, and the complainers said "what current ones?" and had to have them pointed out.

hermannj314•1h ago
That human psychology eventually adapts to tolerate enshittification is probably the main reason we have enshittification.
patall•1h ago
The only problem that I kind of understand are the huge fences surrounding the farms. Because copper thefts are a big problem for them, it is quite common to have 3m high fences all around, which is obviously more gated community like than a monoculture field. And of course, it depends on how the farm is run. Solar farms can be ecological heaven if managed properly, unless growing weeds are just killed of with round-up every few months. Everything else seems more pretended problems, like inverter fans that may just be placed in the middle and should barely be hearable from 100 meters away.
Geezus_42•56m ago
How is that fence any different than the 3m high fence the deer breeder down the road has?
bongodongobob•6m ago
Deer breeding isn't liberal wokeness. Only the good ol boys do that, so it's ok.

Who enjoys living next to a power plant of any kind?
jstanley•1h ago
Of all the kinds of power plant, a solar farm has to be the least intrusive.
bluGill•10m ago
Nuclear is a good candidate - they take up a lot less land mass for the amount of power generated. I used to leave near one, and when my neighbors where asked where it was most pointed instead to a coal power plant many miles away.
IAmBroom•1h ago
Having farmers in the family, I can confirm they are unhappy about living next to anything other than what they grew up next to.

Also, the rainfall. Some farmers go from morning to night never saying a word that isn't a complaint about the rainfall being wrong.

ellisv•8m ago
> Also, the rainfall. Some farmers go from morning to night never saying a word that isn't a complaint about the rainfall being wrong.

Yes. Some of them use proper rain gauges but some just complain about it. Basically none of them understand the difference between a point measurement and an areal average estimate.

chasd00•59m ago
I’ve seen some of the ones out in far west Texas. They’re amazing, you see this blue shimmer on the horizon that looks about the size of a lake and then when you eventually get close enough it turns out to be a huge solar array. There’s some smaller ones just south of dfw that I drive by when going hiking at a state park my wife likes. Still impressive but nothing like the giant farms in west Texas.

the sad thing about this data is how politicized clean energy has become.

the blue states have a lot of energy solar - while the red ones are sparse. the red ones get a lot of sun while the blue ones don't.

rapind•23m ago
Clean energy is woke energy.
FrustratedMonky•22m ago
What is the argument against it? I've never heard any logical reasons beyond hating the Left.

It's like hating bikers, why? The same people that have pickup trucks and swerve to intimidate bikers, seem to hate solar energy. But why?

rapind•17m ago
Rhetoric mostly I'd say. The idea being promoted is that clean energy subsidies hurt the honest Joe coal miner (details being very hand wavy). I'm not convinced it's really that well thought out though and might just be about owning the libs. Maybe there's a MAGA in here that can educate us.
bluGill•12m ago
Because anything one side says the other must automatically and reflexively oppose no matter what. The example here is Right hating on Left, but the Left as the same illogical hate against the right - though in different areas.

This has often been blamed on first past the post voting - if you want to win you have to team up which means your views on Abortion and Environment Policy have to align even though there is no reason to think the two should have anything to do with one another. Since there is no room for thinking each side is correct one one and wrong on the other you have to oppose anything the other does without wondering if maybe they are correct. Now remember that are thousands (millions?) of different issues, and many of them have a range of different answers, yet there can only be one unified position that you support...

I'm not convinced that the various alternatives are really better though. They all seem to have issues in the real world, and too often people will look at what they have an ignore the issues because they want to feel better.

mantas•12m ago
Technically I could see some reasons. Grids need serious upgrades to support personal solar properly. Which is €€€ and, if end-customers would have to foot the bill themselves, very few people would install solar at home. On top of that, at least in my whereabouts solar is receives a fuckton of subsidies. In the long run lower energy prices will pay back those subsidies for the society, but for now I could see why some people ain't happy to foot the bill. Especially when it's usually better-off people installing solar. While poor people end up partially footing the bool.

Last but not least, Chinese domination in modern solar equipment is mind-boggling. At least when I was installing solar, buying western-made would have been much more expensive, to the point that it wouldn't be worth to go through.

P.S. I got solar on the roof myself. „Free“ electricity is damn nice.

jtr1•11m ago
I think you'll have a difficult time comprehending the phenomenon if you look for reasoned arguments. A much more productive framework, IMO, is to see it in terms of a feedback loop between funding sources and the aggregate valence of speech on a particular topic.

The energy industry is one of the largest in the world, with trillions of revenue on the line. The FF component of that industry has every incentive to turn sentiment against upstart competitors, but you do that at scale less by reasoned arguments and more by gut level appeals: "the people who want renewable energy hate your culture and way of life", "renewal installations are ugly and a blight on the landscape of your home", etc.

bongodongobob•9m ago
Yeah, in Oconto county Wisconsin, residents are all up in arms about a solar farm going up. It's the poorest county in the state and would bring in much needed money. The arguments against it are "this destroys farmland", "who will clean the snow off of it in winter", "I don't like how it looks", "static electricity will kill the crops around it", "it will raise the temperature of the surrounding area", "you can't recycle fiberglass so it's bad", etc.
ctime•16m ago
The arid and sunny west ware prime candidates for solar, yet the current administration is doing everything they can to further destroy any chance a future of being carbon neutral with cancellations of many projects.

TFG cancelled a fairly far along project to build 6gw of solar in the Nevada desert just a few days ago known as Esmeralda 7.

The ineptitude and grift of this administration will haunt this country for decades.
