In the middle of the old-growth forests of Congaree National Park in South Carolina, fireflies put on an other-worldly display every May. Thousands of male insects belonging to the species Photuris frontalis flash together at the same time and follow the exact same pattern—a synchronous light show you can see only in few places in the United States.

Scientists and nature lovers have long been fascinated by how such simple insects can work together in perfect harmony

In a new study, engineers from the University of Colorado Boulder have uncovered the mathematical rules fireflies follow to sync up their flashes.

The team’s findings could one day lead to new designs for robots that move in swarms and could help scientists better understand other examples of synchrony in biology—such as neurons firing at the same time in the brain, or cells syncing to the body’s internal clock, also known as circadian rhythm. 

“It’s magical,” said Orit Peleg, associate professor in the Department of Computer Science and the BioFrontiers Institute at CU Boulder. “At certain times of night, fireflies have a single rhythm for the entire group, and they’re very punctual.”

Peleg will present the team’s results Monday, March 16 at the American Physical Society’s 2026 Global Physics Summit in Denver. The researchers published their findings online ahead of peer review.

In the study, the researchers exposed individual male fireflies to a dim LED light—almost like an artificial version of a firefly.

If that light blinked faster than the males, the insects tended to speed up their flashing. If the light blinked slowly, the insects slowed down.

Think of it like an audience member in a crowded concert hall who is trying to join others clapping along to the beat.

“This research opens the door to discovering other examples of synchronization in nature that we haven’t seen yet,” said Owen Martin, the lead author of the research who earned his doctorate in computer science from CU Boulder in 2025.  

Old patterns

The graduate student spent several summers at Congaree over the course of the experiment. 

It’s a swampy area where cypress and tupelo trees hundreds of years old tower over the landscape. Martin remembers spending nights watching the twinkling light from fireflies reflect on the water of the park’s Cedar Creek.

“It makes me think of what that part of the Earth was like before people were there,” he said. “There is this strong sensation that everything is old.”

To study those ancient rhythms, Martin and Peleg set up a unique experiment: The team gently captured male fireflies one-by-one, then brought them into a tent that was completely shaded from all outside light.

Martin then sat in the pitch black and shined the LED at the males.

He explained that, under natural circumstances, fireflies tend to flash about once or twice every second. The group set its own LED to blink anywhere between once every second to once every 300 milliseconds. 

The fireflies kept the beat.

In particular, the insects were most likely to change their own rhythm when the LED blinked almost at the same time as the fireflies, but just a hair off. If the LED blinked right before the firefly, the male often rushed its next flash to catch up to the light. If the LED blinked right after, the firefly waited a little longer to make its next flash.

If the LED was way off from the fireflies’ natural behavior, in contrast, they usually ignored it.

“For a whole season, I spent pretty much every night in the dark watching lights blink at a fixed frequency,” Martin said. “Then, occasionally, I’d get this magical experience where I’d see the firefly just start syncing with the light. I would wonder if I was just seeing things.” 

Swarming robots

He wasn’t. Drawing on their observations, Martin and Peleg developed what mathematicians call a “phase-response curve” for the firefly flashes—essentially, a formula that describes how an outside light source drives fireflies to change their own flashing patterns.

The researchers noted that the team still has a lot of work to do to understand Congaree’s magical fireflies. 

For a start, males in the wild rarely just see a single other source of light as they did in the team’s experiments. Instead, they’re usually in groups of dozens or more fireflies, all blinking at the same time. 

Engineers can also learn a lot from what fireflies do in the wild. Study co-author Kaushik Jayaram, an engineer at Imperial College London, noted that future drones could communicate using visual signals, similar to fireflies.

“Peer-peer optical communication can be lower power and more secure, resulting more efficient swarming and robust aggregations despite requiring line-of-sight, adding a complementary capability to today’s miniature SWAP-constrained drones which largely rely on radio frequency-based approaches,” Jayaram said. 

Peleg added that she envisions a future in which fleets of tiny robots work together to complete tasks without any central command.

“If you’re trying to get a lot of robots to push a large object, and they’re pushing at different times, then they’re going to struggle,” she said. “But if they’re all pushing at the same time, they’ll be a lot more successful.”

Save Misfit Manor: A Queer Anarchist Homestead Needs Your Help

March 13, 2026

PLEASE HELP NICKY REID.

I think a lot of people take words like ‘home’ and ‘family’ for granted, and I suppose I was one of them. I grew up in what I thought was a pretty stable home, a three-bedroom house with loving parents who never actually hit me. But I didn’t know what safety felt like until I was 33 because the stable suburban existence of my seemingly idyllic childhood was dependent on the secrets I kept. About the confusing gender identity that the church my family revered promised eternal damnation for. And about the terrible things that uniformed agents of that church did to that vexing body of mine when I was too small to comprehend it, let alone defend it.

I didn’t even feel safe enough to consciously confront these heinous truths until I met my now girlfriend, Lily, and we were taken in by our dear friends Archie and Em, along with their child, Al. I still remember the first night I spent at the rural homestead they inherited from Archie’s grandmother, sitting around a campfire surrounded by nothing but untouched Appalachian wilderness and other Queer people who understood the unfathomable. Other neurodivergent, gender diverse people who grew up with secrets and the violence they concealed. By the end of that evening, I felt downright high even though I hadn’t inhaled anything stronger than charred marshmallows.

It took me a moment to recognize this euphoria as a simple sense of security; my body unclenching like a fist for the first time since I was five years old, and it would take me another moment still to recognize just how many years I had waited to exhale.

This was the night that my friends became family, and their one-acre property, lovingly dubbed Misfit Manor, became home. I have written about this place before; the ramshackle homestead tucked deep inside a central Pennsylvanian holler, standing defiantly for the unsung cause of Queer rural autonomy in a bastard age of climate apocalypse and imperial collapse. And I’ve written about these people before; my hacker weeb bestie, who I accidentally fell in love with during our overlapping gender transitions; the high school sweethearts who flipped genders, had a child who defied all of them, and took in another longtime friend named James as the missing piece in their polyamorous marriage.

They often form the silver lining in my Queer tribalist tirades against vanilla civilization, but today I speak of them with a tremble in my throat and glass in my chest.

You see, dearest motherfuckers, a couple of weeks ago, what appears to have been a freak electrical fire caused by ancient wiring burned Misfit Manor to the ground. Lily and I still live with our elderly parents most of the time, but Archie, Em, James, and Al barely escaped with their lives, and the flames took nearly everything else; the house, the shed, the ducks and chickens, two charming cats named Toast and Horus, and an abused but impossibly gentle pitbull named Pomni…

All gone. Up in smoke. I drove down the moment I heard, and the strongest people I’ve ever met took turns falling apart in my arms while everything they worked for lay in a smoldering heap beside us.

None of it was insured. Archie’s grandfather had built that house with his bare hands from a dilapidated barn decades ago. They own nothing but the land. However, that fire stole so much more than property. It robbed all of us of a dream of turning that acre into something more. A self-sustaining, off-grid, Queer autonomous zone. One island in what I had hoped would become an archipelago: a confederation of Misfit Manors stretching across the rural rust belt; allowing neurodivergent, gender bending hicks like us (the kind of people the cosmopolitan pride parades left behind) to build a stateless community not unlike that of our Amish neighbors; a sanctuary that would allow us to never have to rely on another straight institution ever again.

In other words, I dreamt of proliferating the safety I found one summer night around the swirling embers of a campfire and turning it into a weapon against isolation and assimilation.

I’m not going to tell you that we ever came close to this dream. I’m not going to tell you that Misfit Manor was some kind of utopian paradise before the flames cruelly turned against us. We are poor people who come from trauma, and like a family of porcupines, we have stuck each other in close quarters many times without even trying. Holding this thing together has been a constant struggle from the beginning, and it has never been easy.

However, I can also tell you that nothing tastes better than homemade bread after three rips of cheap gas station weed. I can tell you that Al taught me how to trust myself after decades of parochial indoctrination just by trusting me to be their “Auntie Anarchy”. I can tell you that I spent the best Thanksgiving of my life playing Cards Against Humanity forty minutes from the nearest Catholic Church. I can tell you that I saw the face of God one summer in a forest shimmering with the lights of a thousand fireflies.

I can also tell you that Archie, Em, and James are the hardest-working people I have ever met in my life and that they have taught me more about anarchism through their selfless kindness than any dead Russian professor ever could. And I can tell you that I am not about to allow this dream to die without a fight.

We will rebuild Misfit Manor from these ashes, but we need your help.

We have put together a pretty bare-bones GoFundMe account, and we have managed to raise enough money on it to dig a new well and install the basic electrical infrastructure, but we still need a used single-wide trailer, which will likely cost us at least another forty grand. We could also use some livestock, a couple shipping containers, and some solar panels so, I can’t tell you exactly how much we’re asking for, probably more than we’ll ever get, but we have managed to make about twenty grand in donations of less than a thousand dollars so, please give anything and we will be beyond grateful, but the greatest thing you can give is to simply spread the word far and wide.

Repost this article or the GoFundMe page attached anywhere and everywhere.

Please, help my family save our home and our dream of a Queer agrarian future amidst the ruins of a post-traumatic civilization. Help us save Misfit Manor.

Hidden rhythm brings microscopic particles into unison


By Dr. Tim Sandle
SCIENCE EDITOR
DIGITAL JOURNAL
January 27, 2026


Scientists have long known that injecting a large quantity of reflective particles into the upper atmosphere could cool the planet - Copyright NATIONAL INSTITUTE OF INFORMATION AND COMMUNICATIONS (JAPAN)/AFP Handout

Swimming in a shared medium makes particles synchronise without touching, according to a new academic study. This means particle physics meets nature – from blinking fireflies to cells in a beating heart, synchronization occurs across nature. Researchers found similar behaviour emerges in a simple system of microscopic particles.

The study showed how , when suspended in liquid, the particles naturally oscillated together as though they sensed one another’s motion. By using computational modelling, the scientists found the particles influence each other’s motion by stirring their shared medium. Applications include vibration control and improving acoustics.

In terms of significance, the research offers a framework for designing adaptive, frequency-tuneable materials. These are advanced, smart materials designed to dynamically adjust their operating frequencies, stiffness, or resonance properties in response to external stimuli like temperature, electricity, magnetism, or mechanical deformation.

Northwestern University engineers have discovered what happens when many of particles come together. The y discovered that groups of tiny particles suspended in liquid oscillate together, keeping time as though they somehow sense one another’s motion. Nearby particles fall into sync, forming clusters that appear to sway in unison — rocking back and forth with striking coordination.

According to computer simulations, the conductor behind this coordination is the liquid itself. As each particle oscillates, it gently stirs the surrounding fluid. Those tiny ripples flow outward to nudge neighbouring particles.

Even though the particles do not directly touch one another, they influence each other’s motions. The motion of the fluid enables the particles to “feel” one another at a distance.

The findings could help explain how complex, collective behaviour emerges without communication or signalling. By moving through a shared medium, individual components can influence one another’s timing. The results suggest that in biological systems, too, the environment itself — whether fluid, tissue or air — may play a crucial role in orchestrating collective rhythms.

Called synchronization, emerging coordination across a group of individuals is common in nature and engineered technologies. Yet the researchers did not expect to see this phenomenon emerge so clearly in a simple physical system.

By combining the detailed simulation with experiments and a simplified mathematical model, the team demonstrated that fluid-driven interactions alone could explain why the particles synchronized. The researchers even could predict which colour (or oscillation phase) each particle would adopt based on its position within the group.

Now that the underlying mechanism is clear, the researchers wish to learn how to control the synchronisation. By tuning particle density, geometry and confinement, future work could turn the collective motion on and off — laying groundwork for programmable materials and microscale systems with functions that emerge from coordinated behaviour.

The findings also offer a new physical framework for understanding how synchronization arises in living systems, where motion through shared fluids plays a central role.

The research appears in the journal Nature Communications, titled “Self-oscillating synchronematic colloids”.

The End of 2025 Must Be the End of the Inane Rule of Climate ‘Optimism’

Source: ResilienceEma

We were supposed to have gone net zero by now: that was XR’s central demand, when we formed it, seven years ago. Can we all please at last acknowledge and take seriously the utter failure to do so? Only such acknowledgement will prevent us from continuing collectively to basically ignore the increasingly pressing need to actually focus resources on a strategy beginning with climate adaptation. We should admit that widely-mandated climate optimism has been actively harmful to the needful acknowledgement of reality – and to the active collective self-protection that we now desperately need to get serious about making happen.

Introduction: What If 2025 Had Already Been the Turning Point?

Allow yourself a very brief thought-experiment… What if 2025 had been the year the UK finally met its legally binding commitment to eliminate dangerous carbon emissions?… What if the mass climate mobilisations of the late 2010s had succeeded in forcing governments to act at the speed science demanded? In that alternate reality, life would almost certainly feel calmer, safer and more predictable than it does now.

As 2025 draws to a close, however, we are confronted by a harder truth. Britain is nowhere near zero carbon. (The CCC thinks we’re about half-way there; it has the figure at 50.4% for 2024 (https://www.theccc.org.uk/publication/progress-in-reducing-emissions-2025-report-to-parliament/ . But even this figure is a gross over-estimate; for instance, because it is not an equitability-based assessment; and because it does not take adequate account of ‘exported’ emissions such as those caused by us due to air travel. Nor does it take any account of the impacts of our climate-dire trade policies: see https://substack.com/home/post/p-181403901 )  The gaps between rationally-required activist hopes, political promises and physical reality remains vast.

When Extinction Rebellion emerged in 2018, its call for net zero by 2025 was deliberately bold: It reflected the urgency of the science and the moral weight of the UK’s historical emissions.

Obviously, Britain and the world have absolutely, categorically, and woefully failed to do this. Now, at the end of 2025, is the moment when we can finally, categorically, and very concerningly and concernedly, state this.

Seven years on, then, it is clear that decarbonisation at anything like the required scale and pace has not happened — and within our current political and economic structures, was always utterly unlikely to.

The Limits of the Old Climate Strategy

That failure leaves us with uncomfortable lessons. The climate crisis is no longer something affecting only distant places or future generations. Whether or not we feel engaged with it, it is shaping the conditions of our lives now.

One lesson stands out: we urgently need a climate movement that is broader, more inclusive and embedded in everyday life. One that reaches beyond ‘activism’ and engages businesses, professionals, local institutions and ordinary citizens alike. If we are to navigate the decades ahead, climate action must feel practical, shared and achievable. And it must feel like it is for everyone.

In short, we urgently need a mainstream climate more-than-movement, a wave of wider mainstreamed action. If we are to have a future. This emergence is what organisations such as the Climate Majority Project are aiming to midwife.

Why Adaptation Has to Move Centre Stage

A powerful way to enable this goal is by focusing far more seriously on adaptation — on preparing for the impacts that are already unfolding. When people can see tangible steps they can take to protect their homes, neighbourhoods and families, engagement is more likely to shift into gear.

This also requires letting go of the idea that decarbonisation alone will save us. Cutting climate-deadly emissions remains essential, obviously — but it is no longer sufficient. Alongside prevention, we must learn how to cope, adapt and prepare.

This is hard, but what I am saying is that it is time for climate activists and thought-leaders (and policy-makers, and diplomats, and on and on) to let go of fantasies of achieving full decarbonisation on what would have been a sane timetable. Instead, we need to pivot hard towards a strategy based in climate adaptation.

We are living now with the consequences of failure, and will do so ever more so for a very long time to come. We need to protect ourselves from and through this long emergency, and demand protection via the state too. Climate realists/pragmatists need to retain and in fact upgrade our ambitiousness: but we need to stop pretending that full decarbonisation is achievable within rational timetables, and switch to calling for the enacting now of protective deep, strategic and transformative adaptation to our terrifying emerging terra incognita. (This will also have the huge advantage of potentially making us popular again: by way of starting where people are, with climflation (i.e. climate-driven cost of living increases), with a rising tide of disasters and rising insurance premiums, etc.)

How does this start in practice?:

At a local level, communities can take part in retrofit programmes that make buildings safer in heatwaves and storms, as well as reducing energy bills. Households and neighbours can work together to reduce flood-risk by choosing planting over paving, or using permeable materials where hard surfaces are unavoidable. Community food-growing schemes, rewilded churchyards and shaded green spaces help cool neighbourhoods while supporting wildlife. Simple water-saving measures — from installing water butts to reusing household grey water — strengthen local water security.

When adaptation becomes the starting point, people understand it. Preparedness cuts through abstraction and turns climate decline into something real — and action-able.

Living With the Consequences of Delay

Here at the end of 2025, we are already living with the consequences of delay. Flooding, heatwaves, droughts and wildfires are no longer rare events; they are becoming features of normal life. And in some cases – look at California, or Sri Lanka, or (closer to home) at the many floodplains that have been and will be built on – the consequences of their not being taken seriously enough as our new never-normal have been deeply disastrous, or indeed very deadly. The idea that we can still prevent at source very serious damage is an illusion. What we can do is reduce harm, protect the most vulnerable and adapt in ways that for starters do not worsen the problem.

This is the moment to prioritise resilience at every level — from reinforcing critical infrastructure to strengthening the social fabric of communities on the frontline of climate impacts, from learning from how global South frontline communities have already been practising transformative adaptation to shared inner work turning climate despair into climate courage.

From Global Crisis to Local Action

The unfolding of disasters and responses over the past year has underlined a crucial truth: climate breakdown is a global more-than-emergency, but solutions must be rooted locally. That’s why, in 2025, the Climate Majority Project launched the #SAFER campaign — Strategic Adaptation For Emergency Resilience. Its aim is to be honest about risk without tipping into paralysis, and to show that meaningful action remains possible.

As we look ahead, this should be the beginning of a new phase of climate action grounded in preparedness. Start small. Talk to neighbours (and Councillors) about shared risks and shared responses: rising temperatures, more frequent heat extremes, higher sea levels and heavier rainfall.

Organise locally. Map risks together. Press councils and national government to invest properly in green infrastructure, flood defences and community-level preparedness.

And it’s not just climate

Tragically, as a result of the historic failure with which I opened this article, we are now moving far deeper into the climate more-than-emergency even than XR foresaw as possible/likely. The temperature acceleration over the past couple of years is horrendous, and likely to continue in the next couple of years. This is of course partly being driven, as my friend the ever-truthful climate scientist Kevin Anderson notes, by CO2 concentrations in the atmosphere that are still rising at unprecedented rates; we’ve already driven global temperatures up by 1.5C and if we carry on we’ll be at or over 2C by 2050 with a real risk of 4C by 2100, which will for sure mean systemic collapse. Also there’s evidence we are over-heating faster than we were previously, due to higher climate sensitivity (with the biosphere now not absorbing CO2 at the same level, among other factors).

Likewise witness the recent truly horrific flooding in east Asia. And so on with novel climate impacts ad nauseum.

But bad as all this sounds, it’s worse than that. Because it’s not just climate alone: there are other massive and in fact existential threats arising, which could be deadly by themselves, as well as degrading the climate prognosis. For meanwhile, at the very same time (and quite appallingly timed!) the rise of AI is drastically worsening the climate situation; as is the rise of Right ‘populism’.

And other planetary boundaries too are being deeply-worryingly crossed, boundaries that we had barely noticed in 2018. Seven of the nine planetary boundaries have now been breached:

https://www.pik-potsdam.de/en/news/latest-news/seven-of-nine-planetary-boundaries-now-breached-2013-ocean-acidification-joins-the-danger-zone .

Don’t double down on ‘optimism’

But I know what some will say in response to this litany of inconvenient truths. They will say that even now, halfway through the dismal failing of the ‘critical decade’, we must focus on being climate ‘optimists’.

This narrative ignores the very real downsides of misplaced optimism. Consider for instance the Polish officer class executed by the Soviets, at Katyn. The very few who survived were those who were most pessimistic about their chances when they were arrested; because they and they alone were sufficiently desperate to try to run away.

This example in the present context might seem overdramatic. But note this: being ‘overdramatic’ is exactly what some of those who fled before Katyn were accused of being.

Moreover: Within the lifetimes of most Resilience readers, the climate crisis will likely take many more lives than the Second World War did; it has already taken several million lives (not to mention the several million who die each year from air pollution, mostly a result of the burning of fossil fuels). If we are to survive what is coming, let alone to manage to flourish through it, then we desperately need the kinds of strategic climate adaptation indicated and outlined above: which false optimism leaves unfunded or even sneered-at. We need to actually prepare, in holistic ways that can work, for the unparalleled storms of our children. For ‘multi-breadbasket-failure’ (the technical term for the coming climate-induced famines). For temperatures that can kill. And for much more unpredictable effects.

False optimism is incredibly dangerous. It stops us taking climate/polycrisis adaptation sufficiently seriously; because it evokes the false impression that things are potentially still going to be more or less fine in the future.

Maladaptation is the failure to adapt properly to a new situation or environment. Maladaptation (or no adaptation at all) follows directly from false optimism.

A Necessary Shift in Thinking

It is, as will be obvious from the above, absolutely not too late to act in meaningful ways: we can seek to adapt, we can adapt strategically, and we can even in due course potentially restart the (in 2025 very badly-stalled) policy-momentum for decarbonisation – by way of the agential, close-at-hand, depolarising, energising effects of getting started effectively, i.e. by way of adapting and growing our resilience. Notching up some (local and larger) wins; …starting finally to turn the tide.

It is not too late – it is never too late – to act in ways that are meaningful to reduce harm and to maximise our chances of a ‘thrutopian’ future. But it is high time for a shift in mindset. The pursuit of a perfectly decarbonised future cannot be our only story. We must also become a society actually capable of withstanding shocks and adapting to a harsher climate reality. And that is a noble enterprise capable of bringing people together.

Again, the above does not at all mean abandoning emissions reduction. It means recalibrating our approach. By focusing on resilience, we may unlock deeper and more durable public engagement with climate action — strengthening communities while thereby building momentum for the emissions cuts still so badly needed. And we may successfully start to depolarise the climate question: which is essential to sustaining any such momentum.

Conclusion: Ending the beginning

Finally then: halfway through the so-called ‘critical decade’ for climate action’, with governments and corporations rolling back on their decarbonisation commitments, the climate-delaying far Right on the rise, the 1.5 degree planetary boundary in the rearview mirror, and energy-hungry AI about to let rip, let us take a breath and agree that this is a very good moment – a necessary moment – to get very real about just how much trouble we are in. The Government in this country [the UK, from where I write] completely lacks a ‘mission’ to actually move to protect its populace from climate impacts. False optimism about our climate future makes it impossible to change that dangerous situation. Whereas changing that situation – getting us protected against the rising tide of climate chaos – is exactly what more and more of us are determined to do.

We need to make the most of this failing Government’s climate agenda while it lasts, and look to give succour to the possibility of successor Governments that could have significantly better (including crucially more adaptation-centric) such agendas: notably, in the UK, a possible post-2029 constellation including a resurgent Green Party (and possibly an emergent Your Party too) in government. For the big political story of 2025 has been the rise of the Greens.

Recognising the extent to which we have failed so far, and the extent to which the mitigation/decarbonisation story is stalled, is a necessary prelude to starting anew. A new phase is upon us. New thinking – and new acting – could make all the difference. Post-optimism, pre-any-‘doom’.

Such exciting, essential change might even make it truly possible to envisage a happy New Year…

We Don’t Need Any More Renewables

Source: Adapt Survive Prevail

The claim is ubiquitous: if we’re to meet our climate goals, we need a mass buildout of renewable energy production. But this claim is false, and worse yet, attempting it will accelerate climate collapse.

Let’s start with the assumptions baked into this claim: 1) Demand is natural and untouchable, 2) Renewable energy production reduces greenhouse gas emissions.

Both are untrue.

The first assumption posits that all demand is good and essential; it’s an inevitability that must be met. Any reduction in demand represents a decline in quality of life and rising demand is natural. The second assumption flows from the first: if demand isn’t met by renewable energy, it must then be met by fossil fuels.

In this second assumption, the point is not that renewable energy reduces greenhouse gas emissions in an absolute sense but that it does so relatively: the greenhouse gas emissions created by renewable energy production–such as the mountains of coal burned to produce solar panels, the carbon-sequestering forests and deserts bulldozed for their installation, the F-gases (which are ~20,000 more potent than CO2) released by wind energy infrastructure, and so on–are lower than if this sacred demand were instead met by fossil fuels.

So in plain language, here is the actual claim: “We have no choice but to meet all electricity demands and doing so via renewable energy increases greenhouse gas emissions by a lesser amount than fossil fuels.”

Now that we have clarity on the actual claim, we can break it down. The reality is this: 1) We absolutely do have a choice because demand is politically, economically, and socially constructed, and 2) The choice between renewables and fossil fuels is a false binary, like telling a healthy person they must chose between losing an arm or a leg.

If we accept this reality, the solution becomes obvious: reduce demand and thus production. The benefits of doing so are not relative to fossil fuels, they are absolute: not fewer GHGs than something worse, but a real reduction. The same goes for the various forms of pollution, land destruction, labor exploitation, and so on, which are fundamental realities of both renewable energy and fossil fuel production.

We don’t need to settle for relative improvements and doing so would only sends us further down the path of ecological collapse, albeit at a slightly different pace and in slightly different ways (an accelerated collapse of biodiversity in exchange for a slightly slower pace of global heating, for instance.)

The next false assumption is that reducing demand would lead to a decline in quality of life. The reality is quite the opposite: a great deal of what drives demand makes our quality of life worse or has no effect at all.

To illustrate this point, let’s take a look at the state of New York, which has a legal mandate to achieve 70% renewable energy production by 2030. The state’s progress toward these goals is widely considered a failure, allegedly because it has not expanded renewable energy production fast enough (legally defined “renewable” energy sources currently supply about 28% of the state’s electricity.) Socialists and progressives have responded to this by campaigning for “the biggest buildout of public renewable energy in history”–without so much as a word about demand.

As we’ve seen, this response rests on the assumptions above: that we must meet demand and that the negative externalities are worth it (if they’re acknowledged at all.) This, to me, is completely insane.

By way of example, here are some demands whose total elimination would significantly help the state to meet its 70% renewable energy goal immediately without installing a single solar panel: cryptocurrency mining and arbitrage, high-speed trading, AI data centers, climate-controlled empty office towers and retail spaces, always-on second homes, powered advertising, after-hours commercial lighting, and idling server farms.

These demands either serve the interests of the financial elite or no one at all, while creating significant harm. (After-hours lighting, for example, is a major threat to biodiversity.)

Something that’s important to understand about electricity production is that it’s built for peak demand, not typical demand. It’s the same principle that has blanketed America in giant empty parking lots built exclusively for Black Friday. Due to their variable production, renewables make this problem even worse: you either have to build enormous amounts of battery storage–which is insanely expensive and prone to toxic fires–or you have to overbuild production capacity by ~400%. Both of those approaches come with massive and unavoidable costs, both financial and ecological; reducing demand, however, does not.

Crucially, very high peak loads have no relationship to quality of life, despite what some people claim. You and I do not experience any benefit when the Manhattan’s 70 data centers or the billboards in Times Square suck up ungodly amounts of electricity at the same time we’re trying to avoid dying in a heatwave. The fact that those data centers and billboards are allowed to make socially harmful demands regardless of competing socially useful demands is a policy choice, not a natural phenomenon. To call for a mass renewable buildout that doesn’t challenge that policy choice is a moral, political, and technical failure.

There are, in fact, many other electricity demands that don’t improve quality of life at all: an entire universe of devices in standby mode; humming forests of server racks idling 24/7; ceaselessly running routers, switches, signal repeaters, firewalls, and WiFi systems; empty retail stores, office buildings, and warehouses that are immaculately climate-controlled and lit up like a Christmas tree; vacant parking lots, building perimeters, and storage yards bathed in flood lights; an all-encompassing web of cameras and surveillance technology filming empty streets; the list goes on and on.

In total, buildings make up 40% of global energy demand but 26-65% of their energy is used when NO ONE IS THERE. It is beyond irresponsible to demand ANY new negative externalities while such profligate waste persists.

And then there are huge demands that are easily fixed, like old buildings using constant-speed–rather than variable speed–pumps to recirculate hot water. There’s a good reason you’ve probably never heard of this: it doesn’t effect your experience. But inefficiencies like this are repeated across our built environment, and they add up to a lot of juice.

Calling for a renewable energy buildout without addressing demand is saying that we must accept a slew of new negative externalities in order to maintain waste and inequality. The heated driveways of the Hamptons are sacred. We must burn coal, level forests, pollute waterways, and exploit slave labor to keep Tribeca pied-à-terres at 74 degrees in the winter. We must lay the legal groundwork for clearcutting the Catskills, so that crypto farms can continue humming along.

That’s the situation at the top. But what about at the bottom? The reality is that there are many gratuitous demands at the bottom which represent an unnecessarily low quality of life. Living in a poorly-insulated, drafty home with the heat and A/C cranking constantly is not luxurious and powering such an arrangement with renewable energy isn’t a real solution.

Fixing wasteful demands at the bottom represent a huge source of potential savings, but in New York, as elsewhere, the state is taking an extremely tepid approach to this problem via subsidized efficiency upgrades. However, the scale, manner, and speed of this process is laughably inadequate and unequal. (My own experience is instructive: I applied for the state’s home efficiency upgrade program, and after months of calls and wrangling, they ultimately said they wouldn’t make pay for any upgrades because the home wasn’t in good enough condition. Unable to afford the efficiency upgrades or to renovate my home, I simply continued running my oil boiler, electric baseboard heaters, and wood stove as usual.) My neighbors–some of whom are renters and thus don’t qualify–have never even heard of these programs.

An approach to home efficiency that actually works would aim for universal weatherization via a free, automatic service: a program representative would just show up at your house and work with you to schedule the insulation, window repair, duct sealing, boiler replacement, etc., no wrangling necessary. Other free improvements would rely on proven techniques like load controls that shift demand to off-peak hours (e.g. your dishwasher would default to running overnight rather than after dinner), displays showing real-time electricity costs, free removal of redundant appliances, more efficient default thermostat settings and deadbands, and vampire load reduction measures.

This is a very incomplete list, but you get the point. None of it exotic, and all of it would be experienced as neutral or positive in quality of life terms. And by improving the living conditions of the working class, it would tie climate action to the struggle for greater equality.

So given that, why is there so much enthusiasm for an eye-wateringly expensive and ecologically destructive renewable energy buildout? Because when it’s deployed in this manner, renewable energy avoids class struggle and ecological education. It appears to be a silver bullet that pleases everyone: nothing fundamentally changes, but the climate crisis is magically solved. For people on the left who are both ecologically illiterate and politically myopic, this is the obvious choice.

But any solution to climate change that doesn’t account for inequality–both of wealth and energy–is doomed to fail. Fortunately, there’s a way to make this process a real engine for redistribution while reducing demand: steeply progressive pricing of electricity. Allocating a cheap, reliable 10-15 kWh per day, per primary residence–enough for refrigeration, heating/cooling, cooking, lighting, electronics, and more–would allow everyone to meet their core needs at a lower cost than they do today. Above that, tiered pricing would function as a redistributive tax on the rich, while socially harmful uses like crypto would be banned outright.

If people were unable to meet their core needs within the 10-15 kWh per day range due to issues like poorly insulated homes, the necessary upgrades would be paid for via the “tax” on the rich. The rich would reduce their exorbitant demand because the highest pricing tiers would be expensive enough to disincentive it. That means the tiers would have to increase exponentially, to the point where paying them would lead to the user no longer being rich. This is by design: for an energy transition to succeed, it must have powerful incentives and disincentives, while also redistributing wealth.

Commercial and industrial users would be treated similarly: socially useful functions and public goods like health care, public service, and education would be granted a cheap guaranteed baseline, while steeply-tiered pricing would disincentivize waste. Harmful users would be banned entirely (or at least face such steep pricing that their model would no longer be profitable), and efficiency improvements would be subsidized by the higher tiers.

Taken together, these measures would allow New York to hit its 70% renewable goal without adding any additional production. In fact, there’s zero chance it meets the 70% goal by 2030 any other way.

For the average person, this whole process would represent not just a reduction in the cost of living, but an increase in quality of life. Their home would be more comfortable, inequality would be reduced, environmental disasters would be less frequent, the night sky would be darker, the fireflies more abundant.

And it would incentivize exactly the kind of innovation we actually need: innovation that increases efficiency.

By way of example, if you wanted your home to be warmer without crossing into a higher electricity price tier, you might spend the weekend building a passive solar air heater or a Jean Pain system or a rocket mass heater or a mechanical windmill. If you wanted it to be cooler, you might increase indoor thermal mass or plant a shade tree or install a windcatcher or build an earth tube or a low-tech adiabatic cooling system. If you wanted more refrigerator space, you might build a root cellar or use a zeer pot. And so on.

All of these techniques already work, but they can undoubtedly be improved. And there are entirely new inventions awaiting our ingenuity, the same ingenuity we’re currently wasting on mind-numbing bullshit like crypto and advertising and AI.

Such innovation would allow us to push past the arbitrary climate goals we’ve set and move into the realm of real regeneration: not merely staving off collapse, but truly making our lives sustainable, in every sense of the word.
