There is a stubborn ghost that cyclically returns to intensely haunt the Italian and European public debate the very moment gas prices suffer a sudden spike or anxiety regarding impending climate goals becomes more pressing. It is the ghost of the atom—an entity that our country firmly believed it had definitively exorcised through two massive popular referendums (in 1987, on the immediate wave of the Chernobyl shock, and in 2011, in the tragic aftermath of the Fukushima disaster). And yet, in this complex year of 2026, we are witnessing a veritable, highly coordinated media and political offensive aimed at fully rehabilitating nuclear energy, aggressively rebranding it as “green,” “clean,” and absolutely “indispensable” for successfully achieving carbon neutrality by 2050.
Intervening to forcefully counter this powerful narrative wave is a fundamental text, one destined to leave a profound mark on the landscape of contemporary environmental literature: “L’illusione del nucleare e la rivoluzione delle rinnovabili”, co-authored by Gianni Silvestrini (Scientific Director of the Kyoto Club and one of Italy’s foremost experts on energy policy) and Giuseppe Onufrio (Executive Director of Greenpeace Italy, a trained physicist, and a historic analyst of global energy dynamics). Premiered nationally during the vibrant, bustling days of the KEY Expo in Rimini, the essay is absolutely not a simple, ideological pamphlet, but a rigorous, highly documented, and irrefutable autopsy of the total economic and industrial failure of the Western atomic industry.
Reading this book today equates to performing a vital exercise in intellectual hygiene. The authors expertly guide us through a surgical deconstruction of the very myths upon which the nuclear “renaissance” is founded, conclusively demonstrating how the much-touted return to the atom is not the ultimate solution to our modern woes, but rather a gigantic, incredibly expensive, and potentially fatal alibi that actively risks severely slowing down the only true, technically and economically feasible revolution we have: that of renewable sources, energy efficiency, and intelligent smart grids.
The Mirage of Mini-Reactors (SMRs) and the Eternal Postponement
The absolute core of the new pro-nuclear propaganda relies almost entirely on one magical acronym: SMR, which stands for Small Modular Reactors. The underlying promise is undeniably seductive: forget the enormous, exorbitantly expensive, and inherently dangerous power plants of the past; the future will be entirely made of compact reactors, mass-produced in factories just as if they were automobiles, intrinsically safe by design, and ready to be quickly installed wherever they are needed.
Silvestrini and Onufrio dismantle this appealing narrative with the absolute ruthlessness of real-world data. SMRs, to this day, exist largely only on beautifully rendered PowerPoint presentations or in the form of astronomically expensive, perpetually delayed prototypes. The book meticulously analyzes the highly emblematic case of the NuScale project in the United States, which was supposed to be the undisputed flagship of this exact technology. After literally burning through billions of dollars in public subsidies, the project was recently canceled outright due to an uncontrollable, massive explosion in estimated costs, which skyrocketed from $55 per megawatt-hour to well over $120, rendering the produced energy absolutely unmarketable long before a single foundational stone was ever laid.
The authors highlight an insurmountable engineering paradox: the nuclear industry has historically and logically built increasingly larger reactors precisely to successfully exploit the vital economies of scale (building one massive 1000 MW plant costs proportionally much less than building two separate 500 MW plants). Reverting back to small reactors fundamentally means actively destroying that vital economy of scale. To somehow mathematically compensate for this massive financial loss, manufacturers would have to produce and sell thousands of identical SMRs all over the world. But in a highly competitive global energy market where renewable energies plummet in price every single year, who is genuinely willing to sign binding, multi-decade contracts for thousands of untested, experimental mini-reactors, whose toxic waste will remain deadly radioactive for millennia? The resounding answer from the global financial markets, when freed from the crutch of massive state subsidies, has so far been a resounding “nobody.”
The Relentless Arithmetic: The Markets Have Already Chosen
The cultural debate regarding nuclear power often tragically runs aground on abstract questions of principle or deep, ancestral fears related to invisible radiation. However, Silvestrini and Onufrio’s essay intelligently shifts the primary focus directly to the specific arena where the atomic industry is already losing its battle in an irreversible, spectacular manner: basic economics.
While politicians and loud pundits endlessly debate in television talk shows, global capitalism has already firmly issued its final verdict. The LCOE (Levelized Cost of Energy, which is the average cost of generating energy over the entire life cycle of a plant) of new nuclear builds in the West is literally completely out of control. The very few advanced third-generation plants bravely built in Europe over the last few decades have effectively become textbook manuals of unmitigated financial disaster. The flagship EPR reactor in Flamanville, France (which initially started with a confident budget of 3.3 billion euros and an estimated construction time of 5 years) has ultimately ended up costing nearly 20 billion euros, actively accumulating over 12 years of agonizing delays. The exact same, tragically identical script played out at Olkiluoto in Finland and at Plant Vogtle in the United States.
Conversely, over the exact same ten-year period, the global cost of solar photovoltaic energy has plummeted by an astonishing 89%, and the cost of wind power by a massive 70%. Today, producing a single megawatt-hour of clean energy from the sun or the wind costs a mere fraction of what it costs to produce it by aggressively splitting the atom, even when strictly accounting for the necessary costs of large-scale storage systems (batteries) required to stabilize the grid. As the authors lucidly point out, actively investing one billion euros in nuclear power today simply means obtaining less than a quarter of the total energy you would successfully obtain by investing that exact same billion in a smart, diversified mix of renewables, battery storage, and targeted energy efficiency. In a modern world where the economic resources of sovereign states are absolutely not infinite, stubbornly insisting on nuclear power actively means stealing vital capital away from the single technology currently capable of rapidly and effectively decarbonizing our struggling economies.
The Tyranny of Time and the Climate Emergency
Furthermore, there is one absolute variable that no parliamentary law and no amount of lavish state subsidy can ever bend, buy, or corrupt: the relentless factor of time. The international scientific community, explicitly through the dire reports of the IPCC, has given us a completely unequivocal, non-negotiable deadline. We must successfully halve global greenhouse gas emissions by the absolute end of this decade (2030) and fully achieve net-zero emissions by 2050 simply to hope to maintain global warming safely below the point-of-no-return threshold of 1.5 degrees Celsius.
It is precisely here that the grand nuclear illusion dramatically and fatally shatters against the hard wall of physical reality. From the exact moment a political decision is made to build a new nuclear power plant, moving through the incredibly complex identification of a suitable site (a politically explosive, highly contentious process in a densely populated and highly seismic country like Italy), the exhaustive environmental impact assessments, the labyrinthine procurement procedures, and the staggeringly complex phase of physical construction and rigorous testing, an average of 15 to 20 years passes in the Western world.
If Italy hypothetically decided tomorrow morning to completely restart a massive national nuclear program, the very first atomic electron would simply not enter the national grid before 2042 or 2045. By that terribly late point, the global climate match will have already been definitively won or lost. Nuclear power is simply “too late”—far too delayed to adequately respond to the immediate, burning emergency. Renewables, on the complete contrary, are incredibly agile, highly modular, and exceptionally rapid technologies. A massive offshore wind or solar park can be thoroughly designed, legally authorized, and fully constructed in a matter of a few short years (often mere months, in places where slow bureaucracy does not impose senseless, archaic vetoes). Physically installing solar panels on the sprawling roofs of industrial warehouses requires only weeks. The essay starkly reminds us that time is unequivocally the absolute scarcest resource we currently have, and carelessly wasting it chasing the slow, fading mirages of the atom is a deeply suicidal luxury.
The False Myth of “Baseload” and the Grid of the Future
Yet another foundational cornerstone of pro-nuclear rhetoric, skillfully and methodically dismantled within the book, is the supposedly absolute, undeniable necessity of a so-called “baseload”—a constant, heavy, and uninterrupted base load of generated power required to strictly guarantee the stability of the electrical grid, a rigid role that has historically been played by massive coal or nuclear plants. The classic, tired argument goes: “The sun doesn’t shine at night and the wind doesn’t always blow, therefore we absolutely need nuclear power for when the renewables inevitably stop.”
Silvestrini and Onufrio, heavily supported by countless, peer-reviewed grid-management studies, conclusively demonstrate that the very concept of a rigid “baseload” belongs entirely to the twentieth century. The electrical grid of 2026, and even more so the advanced grid of 2050, is simply not a rigid, dumb pipe into which one blindly pumps constant energy; rather, it is a highly dynamic, incredibly intelligent, and fully bidirectional ecosystem. The resilient power system of the future (and, in many advanced nations, already part of the present) rests firmly on geographical and technological diversification: massive solar arrays, onshore wind, offshore wind, responsive hydroelectric, and deep geothermal all working in perfect, orchestrated synergy.
When these primary, weather-dependent sources naturally fluctuate, overall grid stability is not bluntly guaranteed by a rigid, massive reactor that is incredibly slow to modulate its immense power output, but rather by a highly flexible, intelligent mix. This includes continent-wide interconnected grids (capable of seamlessly moving excess wind energy from the stormy North Sea down to the sunny South of Europe, and vice versa in an instant), massive electrochemical storage systems (utility-scale lithium and solid-state batteries), pumped-storage hydroelectricity, and, above all, AI-governed “Demand Response.” This advanced software automatically and invisibly shifts heavy industrial consumption or the mass charging of millions of electric vehicles to the exact moments of maximum, cheap renewable production. In this highly flexible, intensely dynamic paradigm, a massive nuclear power plant—which, strictly in order to financially pay for itself, must run at 100% capacity 24 hours a day, 7 days a week—effectively becomes a clumsy elephant in a delicate china shop. It is a rigid, unyielding presence that frequently forces grid operators to completely “turn off” free, abundant wind energy simply because the stubborn atomic plant cannot be easily or cheaply powered down.
Geopolitics and Democracy: The True Revolution
The final, and perhaps most profound, reflection deeply provoked by “L’illusione del nucleare e la rivoluzione delle rinnovabili” is of an exquisitely political and inherently democratic nature. The specific technological choices we make today powerfully and irrevocably shape the exact form of the society we will inhabit tomorrow.
The classic nuclear model is intrinsically and unavoidably centralized, deeply top-down, highly technocratic, and profoundly tied to rigid structures of high military security and deep State secrecy (the incredibly sensitive supply chain of enriched uranium and the dangerous, millennial management of high-level radioactive waste are simply not compatible with a highly open, vulnerable society). Furthermore, the oft-repeated narrative of “nuclear energy independence” is demonstrably false: Europe simply does not mine its own uranium. Blindly relying on nuclear power effectively means merely trading a dangerous dependence on Russian or Middle Eastern natural gas for a new, equally dangerous dependence on uranium extracted in Niger, in Kazakhstan, or heavily refined and enriched by Russia itself (which still largely dominates the global uranium enrichment market).
The ongoing revolution of renewables, on the complete contrary, represents the most inherently democratic and widely distributed form of energy production ever conceived by humanity. It actively transforms everyday citizens from passive, exploited subjects of the monthly utility bill into empowered prosumers (producer-consumers). The rapid, unstoppable proliferation of Renewable Energy Communities, prominently mentioned and championed in the text, allows residential condominiums, small rural municipalities, and local artisan districts to actively generate, freely exchange, and cheaply consume their own clean energy locally. This powerfully emancipates them from the heavy grip of giant, monopolistic energy corporations and effectively zeroes out the massive energy losses associated with long-distance transmission.
Conclusion: Beyond the Illusion
The timely book by Silvestrini and Onufrio arrives at an absolutely crucial, historic juncture. It serves as a vital, highly effective intellectual antidote against the dangerous “rogue nostalgia” of those who would desperately like to forcefully turn the clock of history back to the 1970s. It powerfully reminds us that the ongoing ecological transition is not merely a trivial, mechanical substitution of old boilers for new ones, but rather the single greatest effort of infrastructural and cultural redesign in all of human history.
The stubborn insistence of a certain vocal segment of the political and economic world on continuously proposing nuclear power as a magical panacea reveals, in the ultimate analysis, a deep-seated, paralyzing fear of truly embracing systemic change. Nuclear power is the desperate, ultimate attempt to keep the old, centralized, highly monopolistic world alive by simply changing the fuel that burns inside it. But harsh reality has already turned the corner. The bright sun, the persistent wind, and boundless human ingenuity are already actively writing a vastly different future—one that is undeniably cleaner, radically cheaper, and infinitely more democratic. Finally abandoning the costly, dangerous illusions of the past is the very first, absolutely fundamental step required to successfully build it.
