Attacks on two DTEK solar farms last spring is a good example. They destroyed many solar panels and some of the transformers, which step up voltage for long distances or step it down for use in homes. Replacing the transformers and swapping out destroyed panels allowed the farms, which generate 400 megawatts, to be back up in seven days.
Timchenko said an attack on a thermal generating station, which experienced a similar amount of damage, took three to four months to rebuild.
This is why renewable energy needs rebranding. National defense from distributed energy sources. Energy independence, no reliance on foreign oil. Disaster preparedness. Provide for your own family if you can power your own house.
New jobs by building up domestic manufacturing of solar panels, batteries and wind turbines. These days costs are coming down so you can lower electricity bills too.
Absolutely 100% Right now having solar panels on your house is ‘branded’ as some sort of green save the planet thing.
Putting enough panels that your house can go totally off-grid with a little cutback and usage, that’s as independent as you get. Save money too.
Anyone who is convinced by the benefits on the environment has been for a long time. It’s just marketing towards the people who are already convinced.
There is a troubling aspect, though - most of solar inverters aren’t capable of operating as an island today. Cost-cutting and dumbing-down has occurred.
However, if a village has at least one household with a hybrid inverter capable of generating a frequency for others to follow - and some people who know what they’re doing - some level of disaster preparedness is possible even with today’s tech. (If the grid fails, one disconnects everyone behind the local substation from the big grid, brings online an inverter working in island mode, and syncs other inverters to it.)
Yeah but throw some batteries on that solar, which you really should do anyway, and you’re good to go. IMHO the batteries are what really makes self-sufficiency possible. With a good size solar array and a good size battery, you can be not only a net exporter but more or less an always exporter, rarely if ever taking power from the grid.
Run on sunshine during the day and stored sunshine at night. Unfortunately a lot of places it’s not legal to have a house with no grid connection, even if one isn’t necessary.
Ok I know they’re in the middle of a war and all but seriously how much did the guy who installed the solar panels in the thumbnail hate kids? Lol there looks like so much space to put those couple panels and they’re just like hmmmmmm howabout right here on top of the seesaw lol.
you know what, how about people start selling renewable resources as a solution to energy independence
For me it’s the main selling point. =D
Putin does not like renewable energy for this reason and allows decentralization.
Oil is also about a fifth of Russia’s entire economy, so the less it is needed the worse it is for Russia
Europe should sell ukraine energy at discounted prices.
Decentralizing energy is the best defense. Solar panels belong on roofs and parking lots. Backup batteries belong in neighborhoods. That way when the power plant is down or the lines are cut off, there’s still local power available.
This. Read about Obama era PACE financing to achieve this goal.
Edit. Fuck republicans for nuking PACE funding.
Military justification for an expensive national energy project?
horny government contractor noisesExactly!! Though I don’t understand why so many country’s and civilians are opposed to clean decentralised power generation such as solar, wind, thermal.
The fact that you get to generate your own “free” power, and its less likely to fail in times of natural disaster.
Its essentially “freedom” & “sticking it to the man” in one clean package. Its not what the media or propaganda calls “the green agenda”.
The fact that it also has applications in better national security is a win win.
Decentralised power generation makes you a american patriot! No a green hippy.
Yeah but wind power plants are ugly here instead of even uglier somewhere else that’s NIMBY (Not In My Back Yard).
In fairness, my understanding is that there are a lot of complications with adding distributed power to existing grids. That doesn’t mean it shouldn’t happen, just that there are engineering and safety challenges when power is coming from “everywhere” vs centrally.
And of course, there’s a lot of energy companies lobbying against clean power sources as well.
I hear that quite a bit of the power infrastructure in the US is well past its life expectancy with more coming due for replacement over time. If anything, a national energy plan should account for replacing, upgrading and modernizing a lot of the existing electrical infrastructure since its so critical to the foundation of our current society
This, and the fact that solar and wind are intermittent so you always need a baseline provider, you can’t do it with “green energy” alone.
Local and grid level storage can and should be included, but base-level nuclear is also good.
It’s true, the more decentralized the energy infrastructure, the harder it is to remove or be damaged.
If the grid is down your industry is down. Large scale PV is easily and cheaply trashed with cluster munitions.
Notes made after a storm: a panel with a 30 cm slash from flying plywood keeps producing, just somewhat less.
Geran-2 carries about 50 kg which can be a cluster munition up to 2000 km on the cheap. It is very effective when taking out large scale PV modules which are made from thermally prestressed glass.
Renewables can’t keep a grid up without fossil backup, which is by now greatly reduced. And 750 kV transformers are also very vulnerable. Ukraine grid is now entirely reliant on electricity import from neighboring countries. These high voltage lines are few.
Of the things you mention, transformer stations and baseload power stations are a real problem. One can build them inside a concrete shell, but nobody can rebuild them all.
Of course, it’s a fact of life that one cannot operate a grid without baseload generation. So baseload (thermal power stations) are the typical target. Solar parks are not. If you get a drone to a fuel tank or turbine hall, you have achieved 1000% more than landing in a solar park.
I’ve seen photos of a hole left by “Iskander” in a solar park (I cannot guess what kind of a “genius” fired it). Crater radius about 10 meters, various grades of destruction out to 50 meters. That’s a 500 kg warhead. With only 50 kilograms, would expect it to take out a circle with a radius of 25 meters. That’s some 2000 square meters, containing about 1000 square meters worth of panels. At today’s prices, panels cost about 25 € per square meter. So the damage in panels (excluding frameworks and cabling and work) is about 25 000 €. The cost of the Shahed / Geran drone is probably in the same class. But not every Shahed reaches its target - in fact, most of them don’t - so firing one at a solar park would not be economical.
A Geran-2 is a mass produced 20-30 k$ item and can carry a 50 kg payload up to 2000 km which will destroy PV modules in a 200-300 m diameter with a cluster munitions payload. Such attacks are very cost effective and can be repeated, so rebuilding doesn’t help you.
Wait until you find out how easy it is to bomb a coal plant
And how much more expensive it is to replace it
Not to mention how long it would take to build back up- even with 24/7 work, it could take weeks or months to rebuild while solar has a much shorter lead time, especially if there are stockpiles of panels around
But how come the experts are saying differently?
Which “experts” do you need for what’s common knowledge?
If you took a second to read you’d find their usefulness isn’t withstanding attack, but being able to quickly deploy after an attack.
You’re acting as if there’s some magical form of energy generation that is impervious to modern munitions.
I’ll write it again then: of what use is rebuilding a small scale insular install if your grid is down, and can’t get up because your power plants and high voltage transformers are toast? You industry can’t operate, that’s the whole point of this exercise. The residents and small businesses can survive on small generators, and they do.
Before engaging sarcasm try finding out whether the tree you’re barking up is in the right forest.
You just don’t understand how the grid works especially with decentralized power.
The grid doesn’t work with pure renewable without month-scale storage. Decentralized has nothing to do with it. Most industrial production processes require 24/7/365 power availability. For obvious reasons not many such are still in operation there, despite aggressive load shedding.
If experts disagree with your “common knowledge”, it’s probably actually a “common misconception” which, given the sheer complexity of information in our world, is a fairly common phenomenon. There’s no shame in being wrong about things you’re no expert in, just in doubling down on your error.
(Of course, if you’re an expert too and have evidence to the contrary, it becomes effectively impossible for laypeople to assess without knowing the history current state of discussion in the field.)
Who told you these people mentioned in an article are experts? Argument from authority isn’t, doubly so from imagined authority. Most about activities going on in the Ukraine and those supporting them are grift. Make sure to double-check what these experts are trying to sell you.
I was contesting the general logic of this sentiment:
Which “experts” do you need for what’s common knowledge?
I took this to mean “If common knowledge suggests an obvious understanding, an expert’s assessment is can add no value, as they would either agree or be wrong.” Put differently: “If it seems obviously true to me, it must be true in general.”
TL;DR: If you think you know more than experts on a given topic, you’re most likely wrong.
On a fundamental level, this claim in general holds no water. Experts in a given field are usually aware of the “common knowledge”. They also usually have special knowledge, which is what makes them experts. If they claim things that contradict “common knowledge”, it’s more likely that their special knowledge includes additional considerations a layperson wouldn’t be aware of.
Appeal to Authority as a fallacy applies if the person in question isn’t actually an authority on the subject just because they’re prominent or versed in some other context, but it doesn’t work as universal refutation of “experts say”.For this specific case, I’m inclined to assume there is some nuance I might not know about. Obvious to me seems that large, central power plants are both easier targets and more vulnerable to total disruption if a part of their machinery is damaged. On the other hand, a distributed grid of solar panels may be more resilient, as the rest can continue to function even if some are destroyed, in addition to being harder to spot, making efforts to disrupt power supply far more expensive in terms of resources.
However, I’m not qualified to assess the expertise of the people in question, let alone make an accurate assessment myself. Maybe you’re right, they’re grifters telling bullshit. But I’d be wary of assuming so just because it seems true.
Attacks on centralized hydro and coal power plants are effective, but expensive since requiring several large ballistic rockets with 300-500 kg high explosive payloads.
In contrast to that you can take out a large PV module field for about 30 k$ with a mass produced item like a Geran-2 with a cluster munitions payload. This can’t be cost-effectively protected against, so rebuilding the plant doesn’t help. Attacks taking out vulnerable centralized parts like speciality high voltage transformers which are difficult to source are synergistic, since causing grid partitioning events and potential cascading failures due to overload.
The thumb looks like something one would see in Half-Life 2, I swear…
That tracks.
Civilian life in Half-Life 2 is basically trying to survive with whatever remains after a war.
Civilian life in Ukraine is trying to survive with whatever remains during a war.
