Fossil fuel supply chain makes your country very vulnerable!<p><a href="https://github.com/Lkruitwagen/global-fossil-fuel-supply-chain" rel="nofollow">https://github.com/Lkruitwagen/global-fossil-fuel-supply-cha...</a>: The resulting complex network has 6.09mn nodes and 15.70mn edges and is implemented in a graph database. With estimates of annual coal, gas, and oil demand in 13,229 global population centres and 8,165 global power stations, we use a minimum-cost flow method to estimate global asset-level energy flows.<p>If you want to protect your country, here are your options:<p>1) Invest in nuclear power and nukes (source of Uranium may be a concern). See North Korea vs Iran.<p>2) Solar on every structure, every vehicle is an EV. This will be the most resilient, distributed grid that can never be disrupted. Node level failures (hail on roof breaks solar) can be easily overcome. EVs are batteries on wheels! They can go charge and come back. Some on this forum may be familiar with Cattle vs Pet, Redundancy, Resiliency, Virtualization (--> Virtual Power Plants), etc -- same concepts, but applied to power generation which is designed as a monolithic circuit switched network. The idea of energy as packets, which can be Store-and-Forward (using batteries) will change everything we know about energy.
Maybe if the EV is an all-terrain truck because roads and bridges etc. are still vulnerable.
All terrain vehicles are sufficiently slow and visible that they're arguably more vulnerable in most cases.<p>In Ukraine electric buggies have been used for frontline mobility because they're quiet, the wheeled military vehicles are in demand because combined with even a dirt road they're a lot faster getting around - i.e. one feature of the HIMARS is that it's <i>not</i> tracked.
We're only a few years away from your electric car self driving itself to a helipad and flying you straight across a city in a pre-planned route on a quad-copter that just docks on your car.
If you want to protect your country invest in nukes.
> Invest in nuclear power and nukes
> See North Korea vs Iran.<p>Both countries invested in nukes (it is claimed). Only Iran didn't get there in time, before the US stepped in to stop them (it is claimed). So unless the US lets you, it's probably a bad idea to invest in nukes, no? Or is your point that the US's nuke story was a lie, and that Iran actually should have invested in nukes?<p>> Solar on every structure, every vehicle is an EV<p>Have you done any calculations as to whether this would actually work? My gut feeling is that even if you put solar panels on literally every structure, you'd be far off from managing to power every vehicle. See if I get around to calculating later, but I at least advise you to do so yourself before making this argument.<p>> EVs are batteries on wheels! They can go charge and come back<p>Uh... Cars are fuel tanks on wheels...
The moral of the story is you should always invest in nukes, since if you don't the US will just lie and say you are developing nukes as a pretext anyway.<p>This also applies to WMDs in general.
Yes, Iran’s problem was they didn’t develop nuclear weapons.<p>The lesson all countries will take from Ukraine, Iran, and North Korea is: develop nuclear weapons.<p>Ukraine and Iran both don’t have nuclear weapons and they were both attacked by countries that do. North Korea does have them and they are apparently in no danger of being attacked.
Sure, do the math and get back.<p>First, do the math for millions of acres of Ethanol, a small fraction of fuel additive.<p>Using the same acres for solar with be sufficient for the entire energy (all forms of energy) many times over.
Look man, why haven't you done the math? It's your argument after all. Anyway, a very optimistic calculations means you need the flat area of at least 800 m^2 in a sunny climate, to charge a single electric truck to full power. Plus you need a battery bank to store it during the day, supposing you're charging at night.<p>So, now you do the math how many trucks and how much area for solar panels a typical military has.<p>I don't need to do any calculations for combustion engines: IT'S WHAT THE MILITARY IS USING RIGHT NOW TODAY!
Just for the Ethanol acres. 30 million acres for a small fraction of fuel. Instead use the same acres for solar panels.<p>Annual Electricity Generated is 26,300 TWh/year.<p>Over 6× total U.S. annual electricity consumption (~4,100 TWh/year). This is enough to electrify everything in US.
I have done the math, several times. The last time was to plan a hypothetical solar "highway gas station" capable of charging 100 teslas EVs per hour 24/7/365. Assuming flat ground at Vancouver's latitude, it came to a solar farm approaching square kilometers/miles in scale.<p>10kwh x 100 x 24 = 24,000kwh
Solar panels nominaly produce 1000kwh/m so 24,000m2 of panels... if facing the sun perfectly during normal day/night cycles. But non-equator latitudes need far more land than that because the sun isnt directly overhead, plus winter/rainy days... it is a massive solar farm (and a massive battery) just to replace an average highway gas station.<p>Given that any future 2-lane highway might see a couple thousand thousand EVs each hour, each needing charging every couple hundred miles, the number and size of solar charging stations per mile is crazy.
Don't do the math for homeless people. Most people live in homes. Homes usually have electricity, unless you live in a 4th world country. All buildings have electricity. Just park and plug in.<p>You need to go to a gas station BECAUSE there is no supply of gasoline straight to home. Homes have electricity. Even in sub-Saharan Africa, South Sudan, Yemen, remotest village in India. I don't know where you live, but if your home doesn't have electricity, your country has bigger problems to deal with than buying Teslas and DC Fast Chargers.
Except not every home has a driveway. With on street parking the norm in many places. Trailing a lead to your car on the other side of the road is frowned upon
Highways. Highways need to support people traveling beyond the range of thier vehicles, be that a car or bus/truck. People could also eat and use the bathroom at home, but highways must still make space for restaurants and restrooms.<p>I ran into that problem during covid. I had to do a few work-related 1000-mile drives and they had closed most all the restrooms!
I've done the math. The average car in Canada does 11,000 miles a year. A Tesla isn't great efficiency, it uses about 3.5 miles per kWh. Throw in inefficiency of charging and you're talking about 3MWh per car per year, and with about 25 million vehicles that means about 75TWh a year<p>Travers Solar in Alberta generates about 2.5TWh a year from under 14 sqkm.<p>Build 30 of them and that's 400 sqkm.<p>A 20sqkm by 20sqkm solar plant would power every car and light van in Canada forever (setting aside seasonality).<p>Factor in lower generation in December, you'd need 10 times that amount of solar, about 70km by 70km, 5000 square km.<p>That's less than 1 quarter of 1 percent of the land in Alberta alone.<p>(Of course you wouldn't put it in one location, it would be spread out across the country)<p>Funnily enough 5000 square km is about the total land use of Canada's oil land use (surface use)<p>You'd have a lot of excess power in the summer -- you'd be generating 650TWh of excess power a year
> Factor in lower generation in December, you'd need 10 times that amount of solar, about 70km by 70km, 5000 square km.<p>Or, convert the solar energy to heat, then back to electricity at 40% round trip efficiency. Needs only 2.5x the solar (or less, because some solar goes directly to the users without long term storage). The heat is very storable at scale, even for seasonal storage.
Lol, 11,000 is for all the city-bound teslas that only drive from suburb to the office. Actual average car use is closer to 25,000km/year (15,000 miles is the us average). But cars are not all road users. The "100 teslas/hour" standard is to accomidate trucks too.<p>If you are planning infrastructure like highways, national averages are irrelevant. It is the same debate that Hertz had when it dropped teslas: charging infrastructure is local and rental car locations (airports) cannot support the needed power density.
> Uh... Cars are fuel tanks on wheels...<p>Sure, but you don't have inexhaustible source of crude oil and a refinery in your backyard!<p>But Sun reliably shows up most days. It doesn't ghost. Sunlight can't be sanctioned, tariffed, taxed, embargoed, pirated, nuked, rebuked, rebuffed, offended. Sunlight is also compatible with most religious beliefs (god is light, etc).
> most days<p><i>cries</i>
> a refinery in your backyard<p>Funny thing is, fuel can be transported, so that's not needed!<p>If you want to look at the geopolitics of it, all of the bigger countries do in fact have their own sources of oil and their own refineries.<p>And if you're going the solar route, you still need the raw materials to build the solar panels (and batteries, and EVs) in the first place. They don't grow on trees.<p>I'm sure we'll see a transition to electric <i>some day</i>, it is more efficient purely from a physics standpoint. But I'd be shocked to see the military transition before civilian industry.
Most countries do not have enough to independently supply their own energy needs from fossil fuels, and they need to import more or less continuously, while renewable energy infrastructure needs building out and then lasts a very long time. This massively affects the strategic effects of losing your supply: one becomes an acute problem very quickly while the other is still a problem but it takes a lot longer to become a real problem.<p>I don't think the main focus is on converting military operations themselves to work without fossil fuels, but more that if you can convert your civilian industry then you have a much better overall strategic position because your total demand for fossil fuels is much lower. (Strategy is a lot more than just your military)
You only need solar panels once. They do not need fueling, refueling, lubricants, anything at all.<p>Solar panels have 25 year warranty. Can you think of anything that you have bought or can buy with a 25 year warranty?<p>At the end of 25 years, they will produce 92%. Perfectly acceptable for a few more decades. The latest panels produce 740 - 800W+/panel, this is sufficient for a lifetime without ever having to think of upgrades.
> <i>If you want to look at the geopolitics of it, all of the bigger countries do in fact have their own sources of oil and their own refineries.</i><p>That won't help you if you can't refine it. Russia has more oil than most and has/had lots of refineries. Ukraine has taken out so many of them that Trump is complaining it's affecting the price of diesel (even though the US also has lots of oil and lots of refineries).<p>Oil infrastructure is temporary, expensive and fragile whereas panels work for 30 years.
> > Solar on every structure, every vehicle is an EV<p>> Have you done any calculations as to whether this would actually work?<p>Yes. All cars and vans in the UK drive a total of 320 billion miles a year. My own electric car tells me this would require 80 billion kWh. 1kWp produces 1000 kWh a year, so you need 80 million kWp or 80 TWh a year.<p>My house will easily provide 8kWp, meaning you'd need 10 million houses. There's 30 million homes, and that's before you factor in non-domestic buildings.<p>A single shooting estate in the uk could produce 20TWh a year with solar alone. Throw in wind and that would petty much double.
If you want security the concept of the mega city needs to be abandoned.<p>In a decentralized country you don’t care about terrorism attacks, nuclear bombs, coups, revolutions, drones and what not.
Not just for security - generally speaking if you have high speed rail infrastructure connected to a good and fast public transport grid, there's genuinely no reason to build a huge city.<p>High density housing is very slow to traverse and getting from point A to B in a big city might take more time than getting on a train that takes you to another city 200km away in 30 min. In a traffic jam, you'll be lucky to do 5km in the same time.
Mega cities are a lot more efficient and I think most people would rather live in one than a small town.<p>And they're actually <i>easier</i> to protect because you can build all your bunkers, barracks, drone bays and ABMs close together. The attack surface is a lot smaller. In less urban countries you have to decide what needs protection, and if you guess wrong more people will end up dead.<p>We should be decentralized in terms of <i>power</i>, not geographic distance. A city where everyone has a gun and military training is much harder to attack than 100 villages with the same total population. The important thing is making sure that even if the city falls theres a plan to avoid civilian casualties, and the rest of the country is independent enough to work without it.
“Encircling the cities from the countryside" (农村包围城市) is the foundational military and geopolitical strategy developed by Mao Zedong during the Cultural Revolution and Great Leap forward, building a distributed self sustaining (military) industrial complex. It was very hard to build and maintain. Altho a lot moved to the coastal areas again, there are constant oscillations and negations between the rich costal cities and the hinterland (data centers, taobao villages)
Trading off efficiency for security is not wise unless you are in war. The same applies to supply chains.
By the time you are in a war it is too late. Far better to be prepared.<p>Its not just war either, as the pandemic showed. Trade disputes that lead to sanctions, natural disasters, and lots of other things require the same security.<p>Its worth paying a bit more for the security, for the same reasons people buy insurance.
I am not sure how efficient we are when the US spends like 20% of its budget for military, police and fire depts.<p>Let alone all of the super expensive infrastructure that mega cities need, for example subways, buses, wide highways for traffic, heavy transportation for supply
All of which is more expensive, per resident, in the countryside.
Citation needed. Those are less than 5% of any budget I've seen.
"In peace prepare for war, in war prepare for peace." - Sun Tzu
There's a tradeoff there, because a very distributed society will also be able to resist disruption and control from a central state.
There was far less risk to cities before social media algorithms sent the world fucking mad and helped get a total psychopath into the oval office and tore apart the world order and globalism.<p>But yeah, it's looking like state sponsored terrorism is back on the menu for those in cities, once everyone moves to the countries, small communities can be targeted by random drone attacks by Russians or something. Will be great.
We need more positive stories like this
If every building and other piece of infrastructure essentially powers itself, that means to disable a bunch of targets you now can't just disable a central substation that feeds them, you have to disable the targets themselves, and depending on the nature of the targets that may no longer be economical.<p>It also no longer makes sense to attack the connecting lines between them as well.
Disabling them is a means to deal economic damage, not an end-goal in itself.<p>People built centralized grids because it's cheaper to build and service when the equipment is concentrated in one place. The economy of scale kicks in.<p>If you move to decentralized so there's fewer outages, but now you're paying extra to maintain it, your solution is not as good as it used to be, that's economic damage right there.<p>And your enemy probably will also stop targeting the small decentralized grid elements, so they're not spending bucks on missiles. They can use more of them to hit other parts of your economy that are still centralized.<p>Estimating the net impact of this change is bigger than the article suggests.
> Disabling them is a means to deal economic damage, not an end-goal in itself.<p>Russia's goal in attacking Ukraine's energy sector is to make the country ungovernable. They attack the energy sector in winter because they know that causes suffering and hope that will cause the populace to turn against their government or at least against the war. It's not just a matter of causing economic damage, turning off the heat is a means to an end in ending the war in their favor.
What does the distinction between economic damage and not being an end goal in itself have to do with anything? Either way it's a live goal being pursued and decentralizing will mitigate Russia's ability to inflict pain.<p>You're right that centralized grids are cheaper (as long as the utilities maintaining them are good faith actors) and that switching to decentralized solutions brings new maintenance costs. But this is a war, the choice isn't been idealized central distribution and costs of decentralization, it's between the latter and a grid under siege by missiles. Relying on a grid that's being struck by missiles with no backup plan isn't economical either.<p>Also in your other comment you were claiming PV being outside was "much easier to hit" but now you are saying those systems probably won't be targeted.
> mitigate Russia's ability to inflict pain<p>The crux of the distinction I'm making is right there. Russia is not doing some ephemeral "inflict pain", it's pursuing a clear objective of draining Ukraine's budget.<p>The way I'd do it if I was in Kremlin is something close to make up a list of targets, rank them by (Ukraine's cost to maintain)/(Russia's cost of missiles), pick the top 3-5 and hit them. Also continuously update the cost estimates and reevaluate those 3-5 targets.<p>In this vocabulary, Ukraine moving to decentralized is a cost in itself, so if it does pay that cost to move "energy grid" item down Russia's list, Russia can celebrate it and move on to the next target. If this happens, Ukraine will have paid the cost of moving to decentralized, and will be continuously paying a penalty for it, while Russia's coat of incurring that on Ukraine goes to zero (since the new missiles are hitting different targets).<p>And critically, if we assume moving to decentralized will make it pointless for Russia to hit the grid, deciding how much will it help requires knowing what target they will aim those newly freed missiles at, and how much cost that is going to incur.<p>> you were claiming PV being outside was "much easier to hit" but now you are saying those systems probably won't be targeted.<p>These are all hypotheticals, I assumed we're on the same page about it. We don't really know here in this forum what's going to work. Considering two contradicting hypotheticals in different threads is alright.<p>My comments are not about what is true, what's going to actually happen on the ground. They're about how one should go about arguing whatever they're arguing for, what reservations they're missing, and what assumptions they made they're not aware of.
>The crux of the distinction I'm making is right there. Russia is not doing some ephemeral "inflict pain", it's pursuing a clear objective of draining Ukraine's budget.<p>Again there's an integral relation between those two things. Insofar as that distinction reinforces any point, it would seem to be the decentralization is a cost in and of itself and that Russia would consider that objective achieved once the cost of decentralization was incurred. As you point out there wouldn't be motivation to attack individual PV systems, yet you keep insisting there's a vulnerability to attack even though the whole point of your inflict pain/drain budget distinction is that such an attack wouldn't have a motivation.<p>>These are all hypotheticals<p>Why does them being hypothetical make having contradictory positions on them more defensible? One thing hypotheticals test is whether the totality of your explanations hang together <i>without</i> contradicting each other. And these aren't even distinct hypotheticals that are isolated from each other. They're contemplating basically the same scenario.<p>If talking about Russia not attacking decentralized system because being decentralized was the inflicted cost is the goal, then individual residential PVs aren't a really target after all. If they are a target, then Russia either wasn't satisfied that the switch inflicted damage that met a strategic goal, or you were wrong that they're distinguishing between inflicting pain and meeting some higher level strategic objective. I don't see that the hypotheticals are actually quarantined off from each other, they're about the same thing, so the contradiction can't be explained away by insisting each part of the contradiction was quarantined off from each other in separate hypotheticals.
A hypothetical is not a position. They are a logical/rhetorical tool that let's you see what are the implications of X being true <i>without</i> saying that X is true. The point of a hypothetical is seeing where something leads <i>without</i> making that something your position.<p>One reason to do hypotheticals is to see if X being true leads to any valuable, surprising implications. So that after that you can go back to talking about <i>whether</i> X is true, this time knowing why you need to know it (or skip talking about it if it doesn't lead anywhere interesting).<p>Making two hypothetical that contradict each other is extremely useful and common way to use them. One typical example is case matching. If you show that some Y holds under the assumption that X is true, then you show that Y also holds under the assumption that X is not true; this allows you to conclude that Y is true, no matter whether X is true.<p>In don't know if Ukraine moving to decentralized will make attacks on its grid useless. In two differs branches here I consider what happens if it does and what happens if it doesn't. In response to whatever the other commenters seem to believe in. When someone states X as their position, sometimes I prefer to see what are the implications of it, and if any are interesting come back to talking about whether their position is true. If no implications are surprising, I won't even approach the costlier task of trying to understand if the commenters position is true.<p>You seemed to believe that decentralizing will make grid attacks not viable, and from there try to go to saying decentralization helps. My point to you was that there's a few variables (decentralization penalty, Russia's next best target after grid) that must be taken into account if you were to conduct an argument like that. I'm saying that without stating (or even having) a position on whether decentralization will stop grid attcks.<p>In the other thread the discussion was about whether grid attcks will stop. And my point was that I don't find it obvious that they won't.<p>Strictly speaking, none of this was stating my position. There's so much more to logic and rhetorics than stating positions and defending them.
>Russia is not doing some ephemeral "inflict pain"<p>Oh but it is, there is no other explanation why civilian heating facilities are being targeted during winter otherwise, they don't cost much to fix, and actually cost a lot to target, but they do bring a lot of pain to the civilian population (winters in Ukraine are brutal).<p>And as if it wasn't obvious enough, the anti-ukrainian government bot campaigns that always coincide with the attacks make it obvious beyond belief.
Yes of course, but that is the point. Why do you hit substations when you could permanently destroy the individual targets of that outage?<p>You do it because targeting the individual sites is not economical. If every 1000 units of currency of range you inflict on your opponent costs you 2000 units of currency, you are basically just hurting yourself.<p>You target the substation because with one hit you can deny the service on many smaller targets, something which may not be economical if you targeted them one by one.<p>That means there are targets that would have been attractive targets in a central system, that are no longer attractive in a decentralized one.<p>Generally centralized systems <i>can</i> be run more efficiently, however it depends since electric transmission is not lossless and the construction/upkeep of the infrastructure is not free. That means the geography of the place plays a huge role. The more spread out the individual sites are, the more a decentralized system makes sense.<p>Renewable upkeep is a question of the requirements. I know mountain huts in high alpine areas that run on solar for the past two decades and have had basically zero maintenance cost, if you don't count the occasional shoveling of snow. Batteries of course need to be swapped out as well, if you have them, but they can also last a while. But the cost of running centralized power to a single high alpine hut is incomparably higher (if it wasn't, that is what would be there).
Even the big targets nowadays take hundreds of drones launched to destroy, because of air defense. Air defense seems like one of those thigs that's easier to concentrate around a select number of key sites. You won't put a Patriot next to each residential building, but you can put some next to a big power plant.<p>And the drones today are made with large targets in mind, carrying one bigger payload of explosive. I wonder how they can change if the goal would be to target stacks of fragile solar panelts with best cost efficiency. I've seen on the news yesterday that Russia started targeting bridges more because that have some new payload that's more destructive to them than just a big lump of explosive.<p>I don't know what's actually true here, just some ideas on what else need to be taken into account.
I've been thinking about this (more [1]) and I do believe smaller grids will be the future for many reasons. I guess this is another reason. But the transition from large grids to small grids has no obvious, easy path because a large grid without total market saturation falls apart as maintenance is averaged over fewer and fewer users.<p>One side benefit though is that it would stop utilities being able to push data center costs onto consumers, something that regulators and governments thus far seem completely unwilling to do.<p>Oh and distributed infrastructure and leadership (the so-called "mosaic defense") is (yet) another reason why the Iran war was always unwinnable from the start.<p>[1]: <a href="https://news.ycombinator.com/item?id=49902903">https://news.ycombinator.com/item?id=49902903</a>
Indeed. The future is off-grid and community level mini/micro grids.<p>There is no need to build/maintain transmission network.<p>Legacy grid is production in far away places, miles and miles of transmission, then a distribution network. The distribution network built for homes is sufficient for homes to participate in grid for redundancy. All buildings can produce energy. Rooftop is proven. Next is vertical solar-- which adds ~4 hours of production. EVs become a storage reservoir and supply power back to the grid (V2X). Add some BESS if needed.<p>Villages in developing countries (half the population in Asia, Africa) can go completely offgrid. Start with plugins, slowly upgrade to bigger panels. No transmission network needed.
A key enabling technology for this is long term thermal storage, which I've been emphasizing here. It is claimed to work on a scale of ~100 kW or higher, storing heat at 600 C with losses less than 1% per month and capex of $0.10 per kWh-th of storage capacity. This is very well suited for isolated microgrids.
The transition is off-grid.<p>The technology and the means are there - whats required is the willingness to adopt to the self-powered lifestyle.<p>Many, many folks have done this - stepped off the grid and live on self-harvested local energy sources - however, the grid is powerful.<p>It is difficult for entire cities to do away with it so rapidly .. at least until PV harvesting gets a significant order or two cheaper and more efficient…<p>I think it’s pretty obvious that electric transportation needs to fully adopt integrated energy harvesting. This seems to be an obvious legislative low-hanging fruit.
Individual self sufficiency is a bad solution. It's hard to scale to the point everyone can afford it, and it means risks like your inverter breaking down turn catastrophic so you need to invest in extra backups. You lose a lot of efficiency and flexibility.<p>I think it's way better to make a <i>community</i> grid. That means your home might only have solar without a storage system because there's a shared battery down the road, using cheaper but more dangerous chemistry you don't want in your home. You pay a small share of maintenance costs and pay off investments you helped decide because it's a co-op. And if that's not enough you can exchange with another neighborhood.<p>Basically I'm saying power should work like the internet. Independent systems that don't need to be self sufficient, but they're still resistant to failure because there is no centralized control.
They are also the cheapest source of energy with the fewest dependencies. The last part is why they will remain illegal. The power structures of society will do anything to maintain themselves, and the current power structures are largely based around exchanging money for essential commodities. This doesn't work if they stop being essential.
[flagged]
Gas and diesel generators are charging small batteries (3coflow types), at least on the frontline because solar panels are good ways to invite incoming fires
This is greenwashing.<p>The article suggests that renewables are somehow more helpful in a war when your grid is targeted by drones and missiles. It doesn't do a comparison to back it up though.<p>Decentralized power production vs. centralized does make sense: decentralized doesn't offer a single point of failure taking out which causes a lot of damage.<p>But can't energy from fossil fuels be generated in a decentralized manner too? Sounds only better than renewables because it doesn't go up and down throughout a day, and doesn't need grid to amortize the jumps.<p>Renewables sort of need to be out there in the open to harvest energy from the elements. Solar needs sunlight, wind needs to spin its huge blades in open air. A diesel generator, on the other hand, perfectly goes underground, much harder to target.<p>So the article doesn't really establish that renewables offer a clear advantage over fossils in a war.<p>Upd: some comments below have convinced me that fossils don't decentralize as easily as renewables.
>But can't energy from fossil fuels be generated in a decentralized manner too?<p>If you sit on an oil well, perhaps. In practice every static part of the production and distribution chain is a centralized target: from wells over refineries to depots, roads, harbours and finally power plants. You simply can't run fossils in a distributed local-first approach. That's also the reason why even for a massive oil producer like Russia, Ukraine can cause billions in damages with drones costing a couple hundred grand.
A drone blows up 1kWp solar panel you lose about 1Mwh in a year assuming it’s completely broken.<p>A drone blows up an oil carrying road vehicle you lose 350Mwh instantly.<p>You blow up a pipeline you knock out 1 million MWh a day
The drone will disbale more than one of those 1kW panels if it hits an array of them. Panels are stationary, easier to target than vehicles.<p>Could you also motivate the choice to compare Wh of energy lost, instead of, say, US dollar cost of the damage? Sounds a bit odd, because Wh is not the currency I pay bills with.<p>How much does it cost to replace an array of solar panels, compared to the cost of sending another diesel truck (and paying for the destroyed one + its fuel)?
Solar panels are dirt cheap. Which idiot would send drones to hit a solar panel? Going by your economic argument, use drones that cost hundreds of thousands of dollar to hit something thats costs 10 bucks?<p>Do you think thats sound strategy? The military generals in US would accept that?
>Could you also motivate the choice to compare Wh of energy lost, instead of, say, US dollar cost of the damage?<p>Well there's an integral relation between the two, more kWh lost is more dollars lost. They both proxy for some venn diagram overlap that includes damage, cost, lost resources, and it's perfectly legitimate to reason from any permutation of those. It's notionally possible for different tech to attach those costs in different ways but in this case I would put the burden on you to explain the practical difference that you think cashes out in an advantage diesel has.<p>I'm not sure why you think a truck would be cheaper necessarily: smaller PV systems can range from $10k to $20k with no fuel payload. Is a diesel truck with a full payload of fuel really cheaper than that? And is a diesel truck supposed to be fueling just one house? It's likely a single point of failure for a network of people depending on it at a time when bridges are getting bombed, and therefore an instance of centralization and attractive target for attack. And you said yourself you didn't think PV would be attacked because decentralizing in and and of itself inflicted the economic damage yet you've once again gone back to imaging a diesel advantage in the event of PV getting attacked.
> And is a diesel truck supposed to be fuelling just one house? It's likely a single point of failure for a network of people<p>Completely correct, but then go one step further: Where is does that truck fill up? At a depot where many other trucks do the same. That's an even more tempting target - centralised, stationary, flammable.<p>I do not think that there is an equivalent node in the solar alternative.<p>And where does that fuel depot get resupply from. "decentralised" fossil fuel infrastructure isn't really a thing that exists.
Fair points.
> Panels are stationary, easier to target than vehicles.<p>is the most ridiculous thing I've read in a long time.
> Panels are stationary, easier to target than vehicles.<p>Panels are small, numerous and widely dispersed, easy to install quickly and incrementally, and non-flammable.<p>Basically the opposite of (also stationary) centralised fossil fuel infrastructure.<p>It's clear which one is the more tempting target if you have a finite stockpile of drones.
You're comparing diesel to PV which doesn't speak to the merits of PV vs centralization. There's also the massive disadvantage of fuel distribution from diesel, which is a form of centralization and bottlenecking, and then there's fuel shortages and costs which PV doesn't have to bother with.<p>Also is Russia targeting individual PV systems? That's tantamount to targeting individual residences which, if we're granting that, there's no amount of decentralizing that would ever mitigate those attacks so diesel vs PV would be moot.<p>Lastly I don't think that's what greenwashing means. Greenwashing isn't representing renewables favorably, it's tying some external negative practice to language of environmentalism with vague buzzwords and questionable claims of environmental benefits to make that thing look better. But in this case there's no external thing being tied to environmentalism, we're just talking about PV directly.
A diesel generator needs a supply of fuel that can be trivially blockaded as Iran is so successfully doing.<p>The whole world is suffering from the effects of that disruption.<p>The supply of diesel itself also requires refineries and they can't be moved or rebuilt quickly either.<p>Ukraine is doing a sterling job of attacking Russia's refineries. All the portable diesel generators in world won't help you invade another country if you have no fuel to run them and no supply lines.<p>A small portable balcony setup costing a few hundred dollars, the type sold in supermarkets in Europe, will run every day and keep you alive.<p>There's nothing the enemy can do about it other than a direct hit and that would take out your generator and fuel anyway.
Remotest villages in India were doing gobar gas plants in 80s/90s. What you are saying is possible.<p>If you have enough cows/biomass, perhaps you can have a home biomass to methane converter. Then you can use it for cooking, heating, etc.<p>You can convert a petrol car to a CNG car.<p>You could also have a coal to liquid plant in the backyard and generate diesel or petrol.<p>You have to do without any cooling though, fridge, AC, etc. Cold can't be created. Without electricity, just with chemicals fuels, it is unlikely.
I don't think they have to worry about lack of access to cold for the next few months. I believe you're accurate re: India and sources of biomass in that context and the possibility of some processing/conversion, but how representative is that of the resources at disposal of the typical person in Ukraine? I imagine more urban residences with electricity and not a lot of cows.
decentralising your fuel production and to a lesser extent distribution is not easy either though.
> But can't energy from fossil fuels be generated in a decentralized manner too?<p>How would that possibly work? Everyone has their own oil well and refinery? Their own fuel depots?<p>And even if you were able to build all that, we would basically have giant bombs waiting to be ignited all over residential neighborhoods during war time...<p>I would invite you to think through the logistics of what you propose before you launch into multiple paragraphs that assume those logistics are solved.
That's not what greenwashing means. Greenwashing refers to marketing that sells a product as environmentally beneficial, while it's not in reality.<p>Your claim is that they're selling a product (renewables) as beneficial for the war, while it's not. If I were to invent a term for that, it might be "camo-washing".<p>Whether your argument makes sense or not, I don't know. But you fail to note the drawback of a diesel generator: it needs diesel, and thus logistics.
I meant greenwashing as pulling a reason to make something about renewables out of thin air. In this case article's choice to center it's argument on renewables is greenwashing. Maybe I need a different word, not sure.<p>The argument that decentralization (diesel or renewable) helps makes sense to me. What they do though is attribute the benefits of decentralized to renewables (ignoring how many buildings are powered by diesel in Ukraine today, those which did not receive that grant from Denmark to do solar), then completely skip potential downsides of renewables, and draw a conclusion from there.
I don't think it's out of thin air, it's the reality of what's actually being used in Ukraine, and as comments in this thread have borne out it seems to have legitimate benefits, and so doesn't qualify as greenwashing.<p>Also if there's greenwashing, it means some questionable practice is being green washed. Apparently you think the idea of decentralization is the thing in this case... but you agree that decentralizing is a good idea and are more against the merits renewables, which is an anti renewables argument but not a correct diagnosis of something being greenwashed.
Yeah, I agree greenwashing is not the word here. I don't know what is, but if anything I would say you're trying to express something that is in an important sense opposite to greenwashing (greenwashing is trying to make something look good by falsely presenting it as eco-friendly, you're accusing something of boosting renewables by falsely presenting it as tied to them)<p>And yes, decentralization is the core aspect that is important, but renewables are importantly much more decentralized <i>end-to-end</i> compared to a diesel generator, because renewables, once in place, have no real central point of failure, while the supply chain for the diesel in the generator still has very important central points of failure that can be attacked (and explode quite easily due to the large amounts of flammable material they are carrying). Distributing the generation does help smooth over short-term disruptions but the overall throughput in the longer term can still be disrupted.<p>Also, while renewables might be out in the open, they are cheap and spread out over a wide area, which makes them pretty cost-ineffective to attack compared to more concentrated facilities.
> The argument that decentralization (diesel or renewable) helps makes sense to me.<p>Sure, but also in the real world, fossil fuel infrastructure is always centralised. "decentralised diesel" might exist in the sense that you can run lots of generators all over, but that's energy consumption not energy supply.<p>Those generators have to be supplied with fuel or they're useless. That supply is always centralised. Fossil fuels cannot be decentralised in the same way as solar.
