The plan to stop the melting of the Arctic is so simple that it sounds crazy: freeze it again

by

Global warming does not affect everyone the same way. Without going any further, Europe is the continent that most is warming according to the World Meteorological Organizationbut there is another place where the heat has turned the turbo: the Arctic. The North Pole heats up four times faster than the global average. Additionally, sea ice is at historic lows since records began 125 years ago. Faced with this climate emergency, a research team has come up with something so logical that it is surprising for its apparent simplicity: is there a lack of ice? Well, we manufacture more artificially. So they have left the laboratory and gone to the field to see if it is possible. The idea. The company Real Ice, in collaboration with the University of Cambridge, drills into sea ice in the dead of winter and pumps seawater onto its frozen surface. The water, when exposed to that extreme cold, freezes immediately and adds an extra layer of ice. Now that they have the base mechanism, Real Ice is adapting pumps used on skating rinks or oil platforms to power them with renewable energy. According to The GuardianIn a recent test, the team pumped 50,000 tons of water onto 1.5-meter-thick ice at -40ºC and managed to increase its thickness by 0.50 meters. Why is it important. Although emissions reduction is the only long-term sustainable solution, while it arrives it is necessary to explore techniques to save time because the Arctic melting is a problem with chain consequences that affect different scales: At the local level it poses a threat to Inuit ways of life and fauna such as the polar bear or the walrus, in addition to destabilizing the ecosystem. At a global level, it can alter weather patterns. Sea ice is a kind of planetary air conditioner: its white surface reflects solar radiation, something that the dark ocean does not do (albedo feedback). That extra warming of the Arctic is also related to a wavier, slower jet stream which can lengthen and promote heat waves or floods. Furthermore, the thaw goes hand in hand with the thaw of the permafrostwhich releases methane and further accelerates warming. Context. This project is part of the program RASI (Re-thickening Arctic Sea Ice), a public – private initiative in which the University of Cambridge and two private companies, Real Ice and Arctic Reflections, carry out research that combines rigorous scientific models with real experimentation in the Arctic. As a curiosity, it is not the only proposal: there are others more controversial that propose dispersing sulfate aerosols in the stratosphere to reflect sunlight. In detail. The first study in the last 2024/2025 campaign has confirmed that the test areas ended the winter up to 32 centimeters thicker than the control areas. According to the study, this difference is similar to what the Arctic has lost in the last 50 years. Furthermore, at the end of the winter campaign they observed that this new ice remained whiter and brighter during the melting season, so it seemed to melt more slowly, improving the albedo. Yes, but. On paper it looks very good, but the scientific community has its doubts. An analysis of several of these proposals published in the journal Frontiers in Science concluded that they did not successfully overcome the criteria of feasibility, cost, governance and environmental risk. The underlying criticism is that it could give the false sensation that there is a technical shortcut that relaxes the pressure to reduce emissions. On the other hand, a test in a specific area is one thing and the price of scaling this technique to the entire Arctic is another.

“Cyclical” productivity sounds great as a way to organize work according to the rule. The problem is that it’s a bluff

by

Patricia Gosálvez told that for some time now talks about how to organize the work agenda according to the phase of the menstrual cycle have been the order of the day. There are different approaches and different discourses, but the general idea is the same: “do social tasks when you are ovulating and reserve planning and solitude tasks for your period days.” We knew that ‘cyclical productivity’ swept TikTokWhat we didn’t realize was that he was already proselytizing among the management class throughout the country. And we shouldn’t be surprised. A priori, the idea sounds like empowerment and militant feminism. The question, however, is whether it makes any sense. But… what exactly are we talking about? In general terms, we can see it as a work adaptation of something that has been talked about for quite some time: the cycle syncing. A self-care practice in which things like diet, exercise routines, or lifestyle habits are adjusted to match the hormonal fluctuations of the menstrual cycle. Applied to the workplace, the month is divided into four phases and tasks are distributed: planning is reserved for bleeding, during the follicular phase work is brought forward, ovulation are “ideal days to negotiate, ask for a raise and everything that needs power and security” and the luteal phase is fantastic for detailed work. It sounds good, but it’s a bluff. Especially since the model assumes a hormonal cycle that most women don’t really have. In general, cycle syncing is right that there is an infradian hormonal cycle (that is, with a period longer than one day), but it jumps to the idea that it is a closed scheme that is easy to program without a break in continuity. In fact, there are two large systematic reviews on this sort of thing that do not support the ideas of cyclical productivity. According to the latest meta-analysis from 2025there is no robust evidence that cognitive performance (neither attention, nor memory, nor executive function, nor spatial ability) changes over the cycle. On the other hand, the most robust studies of physical performance also find that the cycle effect is “trivial”. This does not mean that menstruation does not have an impact very significant in the lives of women and that pain in many cases is a huge problem. It doesn’t even mean that PMS doesn’t exist. What this means is that the hormonal cycle does not seem to serve to schedule tasks with that level of detail in the general population. But it does have a problem. And behind the façade of ’empowerment’, the truth is that there is a very problematic message that “women’s competence fluctuates with hormones.” It is something that reinforces stereotypes and, as we have seen, is a lie. As the endocrinologist Carme Valls said to Gosálvezis an idea that “makes women too biological, too animal.” And he does it without contributing too much. Above all, because as Valls continues, in a normal cycle the variability is minimal: “40% of women hardly feel anything.” That is to say, although from an individual point of view knowing the cycle is very useful, from a population point of view it introduces noise. The problem is not the initial intuition, nor the idea that talking about the rule is good. The problem is the promise of productivity associated with it. A promise that, as we see, in general terms has no relationship with reality.

undetectable sounds that hack AI chats

by

You have a podcast or YouTube video playing at home and, without realizing it, it starts playing a sound that is undetectable to you, but is sending commands to your AI assistants. The assistant then begins to share sensitive data with the attacker or installs malware. We already had the prompt injection attacks and now comes the injection of sound prompts. The experiment. It sounds like science fiction, but it is perfectly possible. A team of researchers from China and Singapore have discovered a way to create malicious sounds that can “hijack” voice AI models, causing them to execute commands without you knowing or being able to stop them. In statements to IEEE Spectrumthe leader of the study assures that “It only takes half an hour to train this signal and, since it is context-independent, it can be used to attack a model whenever you want, regardless of what the user says.” The authors tested this technique against thirteen AI models, including services from Microsoft and Mistral. In the test they had these models perform sensitive searches, send emails with user information and download files. They achieved a success rate of between 79 and 96%. Undetectable. LALMs (Large Audio Language Models) have a critical security flaw. Since they receive instructions in audio format, it is possible to inject malicious commands into manipulated sounds. Worst of all, these sounds are not voices with instructions, which would be fairly easy to detect, but rather they use a method called “convolutional mixing” that masquerades the sound as a natural reverb or echo in the room. Why it is important. An attack of this type completely changes the defenses that we have internalized (do not click on links, do not download things, do not give out your data…). Something as harmless as playing a YouTube video, a podcast, or watching a TikTok in the background can trigger an attack without us even realizing it. If we also take into account that the power of AI agents, such as the recently announced Gemini Sparkis precisely having access to our entire digital life, an attack of this type can wreak havoc. Hijacking attention. Pre-instructing the model with examples of malicious commands so that it ignores them barely reduces attack success by a dismal 7%. Similarly, asking the AI ​​to “reflect” on whether its response matches what the user has actually asked for only manages to detect 28% of attacks. Current security measures are useless because manipulated audio hijacks the model’s mathematical “attention,” inducing the AI ​​to execute high-confidence outputs and making it impossible to distinguish between a legitimate user command and an adversary attack. Open source. The “good” part is that at the moment this type of attack has only been able to be carried out with open weight models. However, researchers have seen that once malicious audio is trained, it can be transferred to breach closed models. As we said, the authors put it to the test with services from Mistral and Microsoft. At the moment Mistral has not commented, but Microsoft sent the following statement to IEEE Spectrum: We appreciate the work of the researchers to deepen the understanding of this type of technique. This study assesses model resilience through controlled, direct interactions with the model itself, helping to define our approach to building resilience. In practice, AI models are often integrated into user applications, and we provide developers with tools and guidance they can use to implement additional layers of protection to help safeguard users.

The ‘Chinese Netflix’ has designed a plan for AI to generate the majority of its content within five years. It sounds risky

by

iQiyi, China’s largest video streaming service with more than 400 million monthly active users, announced in its annual content presentation in Beijing which expects AI to generate most of its movies and series within five years. Its founder and CEO, Gong Yu, summed it up before a room of producers and directors with a succinct phrase: “It’s a once-in-a-decade opportunity. We have to go with the tide.” Why is it important. iQiyi is not a minor platform betting on a trend. It is the subsidiary of streaming of Baidu, shares with Alibaba and Tencent the online video oligopoly in China, and operates in the streaming largest in the world by number of users. Whether it decides to pivot towards content generated entirely by AI affects how the rest of the platforms that tend to follow in its footsteps will produce, distribute and monetize audiovisual entertainment. The context. iQiyi has been losing audience for years to Douyin, the Chinese version of TikTok owned by ByteDance. Short video has cut into the time that Chinese users spend on long video platforms. The result is that its revenue has fallen by 13% in the first quarter of 2026. The company, listed on Nasdaq, has also applied for a second listing in Hong Kong seeking closer capital. The announcement of the pivot towards AI comes from a certain pressure. In detail. The center of the plan is Nadou Proa suite of AI tools that the company presented on April 20 and that, it says, can manage practically the entire film production process: script, storyboardvideo generation and final assembly. The software does not work with its own models, but rather integrates those of several direct competitors: Alibaba, ByteDance and Kuaishou for the domestic market; Seedance 2.0 and Google I Spy 3.1 for the international version. iQiyi has also launched a library of virtual assets and “signed” talent for third-party creators to generate new content using the platform’s characters and universes. The incentive strategy to attract these external creators involves… An extra 20% on advertising and subscription revenue for those who produce content with Nadou Pro. An inaugural catalog of 16 AI-generated films, in science fiction and anime. A public goal: release a commercially successful AI-generated film before the end of summer 2026. Yes, but. The question that remains to be seen is whether anyone will want to pay to see that. Recent history does not invite optimism. AI-generated video has shown some traction on TikTok and Instagram, where the cost of user attention is practically zero and the scroll Erase any disappointment in a tenth of a second. That this tolerance is transferred to a two-hour feature film for which someone pays a monthly subscription is another story. Between the lines. Gong Yu has said that iQiyi will continue investing in professional production, but in the same sentence he has clarified that this type of content will reduce its relative weight on the platform. The direction is quite clear. The risk is that viewers of C-dramas and the anime Koreans who have made iQiyi great are exactly the type of audience that has the least tolerance for ‘AI slop‘. Main loser? The producers and directors who filled that room in Beijing when Gong Yu announced the pivot. iQiyi has designed a system where independent creators can use Nadou Pro to generate content and earn a percentage of the advertising revenue. It’s the same model that YouTube has applied for years with human content, now transferred to AI. In this scheme, professionals in the sector go from being the protagonists of the production chain to being, in the best case, supervisors of a process that they no longer control.

In the middle of 2026, a childhood without mobile phones sounds impossible. A town in Ireland is doing it

by

Greystones is a small town on the coast of Ireland, more specifically in County Wicklow. 22,000 inhabitants, semi-detached houses, coastal landscapes, a railway network which allows you to reach Dublin in just over half an hour… A priori, it is the perfect town to enjoy a peaceful life just a stone’s throw from the bustling Irish capital, where companies such as Google or Apple. However, in recent years the town has been in the news for another, very different reason: his crusade against the use of smartphones among the children. His case shows that it is still possible to live a cell phone-free childhood. What has happened? That the small town of Greystones (Ireland) has strived to teach the world a lesson: to show that in 2026 it is possible to keep children away from mobile phones, Instagram, TikTok and the rest of social networks. We just need to join forces to change the sign of social pressure. The initiative is actually not new. Greystones launched their crusade in 2023when it already aroused the curiosity of the rest of the world. However, the unknown remained as to how the experience would turn out. Now we already know. Where does the idea come from? The debate around what age Children should start using mobile phones or social networks and the influence that these have on them is not new. It’s not a concern unique to Greystones, either. There however it happened something interesting during the pandemic. When students returned to classrooms after lockdown, Rachael Harper, headteacher at St Patrick’s School, found that some children were having trouble sleeping or struggling to concentrate. She wasn’t the only one to notice. Other colleagues confirmed that they perceived similar attitudes among their primary school students. What caused them? It didn’t take long for teachers to focus on the use of cell phones. They even encountered children who controlled their calories with apps. Eoghan Cleary, a teacher at another Greystones school, also found that his students admitted seeing violent content on the Internet. The sum of all these factors led several primary schools to send a survey to around 800 parents When asked about the topic: more than half acknowledged that they noticed their children were anxious. In some cases they had even sought professional help. It was enough for the city to decide to make a move. What exactly did he do? We mentioned it before: join forces. Eight primary schools in the Greystones and Delgany area came together to launch an initiative they named ‘It Takes a Village’ (‘It takes a whole village’). Its main tool was the ‘voluntary code without smartphones’, a community pact that basically encourages residents to prohibit children from using mobile phones during their primary education period. In practice this is equivalent to keeping young people away from networks and smartphones until they turn 12 and enter secondary school. The pact is of course voluntary, free and failing to comply with it does not result in fines, but the idea is that whoever signs it applies it both at school and at home. Were you that worried about the issue? It seems so. “As principal of St. Patricks Elementary School I have observed growing concern among parents and teachers,” Harper admitted in 2023 in a column opinion published in Guardian. “The level of anxiety of children in schools has grown steadily, since easy access to online and mobile content has become a threat to childhood. We felt the need to act. The process started with a realization: childhood is becoming increasingly shorter.” Has it worked? That was three years ago. Now we finally know how the initiative is working. Recently The New York Times dedicated an extensive report in which, among other issues, it confirms that the campaign has had a more than reasonable reception. They have supported her 70% of parents and above all it has penetrated the town, moving to businesses and politicians. He has even made his mark beyond Wicklow. Shortly after it was launched ‘Smartphone Free Chilhood’a citizen movement that advocates delaying children’s access to smartphones at least up to 14 years. How has he achieved it? In 2023, Harper herself insisted in that, if it really wanted to work, the initiative had to go beyond the classrooms. “It’s not about enforcing a code. It’s about building a strong network of services that helps children, families and teachers deal with anxiety-related challenges.” The report of The New York Times suggests that goal is also being achieved at Greystones. Beyond what parents do at home, the campaign is completed with training workshops and events such as phone-free beach parties. Even with the commitment of local businesses. For example, one store has offered to help children who need to locate their parents. Is it so important? Yes. And for a simple reason. The very name of the initiative (‘It takes a whole village’) makes it clear that, to succeed, the campaign must play with collective pressure. And it seems that he is achieving it. “In networks everything is collective. Addressing it jointly is the best option,” recognize Jennifer Whitmore, member of the Irish parliament and mother in Greystones. In other words: delaying a child’s access to mobile phones and social platforms is very easy when they are surrounded by other kids of the same age who also do not use them. “What Greystones demonstrates is that parents and communities are not powerless,” agree Clearly. Is it that dangerous? Harper insist in that the initiative is not based on “anti-technology stances” nor does it want to deny children the use of smartphones. The key lies rather in rethinking the times and what it means to have a mobile phone. “Our goal is to ensure that they are adequately prepared and emotionally capable to take on the responsibility that comes with having a smartphone when accessing secondary education”, claims before citing a UNESCO report that suggests it can take up to 20 minutes for a child to concentrate … Read more

Opening a company in a single visit to the administration sounds like utopia. In China it has been law for years

by

Bureaucracy is probably one of the few things on which there is almost absolute consensus: everyone hates her. Queuing from window to window, discovering that you are missing a photocopy, returning another day because the official who signs is not there… an administrative ordeal, but it doesn’t have to be like this: years ago, in China they set out to end the labyrinth of procedures with one objective: so that more companies can be created to be more competitive. One visit at most. The ‘one visit at most’ reform It was promoted in the province of Zhejiang in 2016 and today it has spread to more territories in the country. The central objective is to unify all the procedures into one, so that those who want to form a new company only have to go to the administration once, avoiding the “walk” through different windows. It does not only affect the creation of companies, but all types of procedures such as birth certificates, registration records, registrations for health insurance and health cards. In addition, there are many procedures that can be done electronically, it is what they call ‘zero visit’ and the idea is that over time more and more processes will be added to this list. How it was before. Before this reform the process was not only much more tedious, but also much slower. a businessman counted in CGNT To get a permit you had to go through a lot of procedures, the lines were very long and it took several weeks. And if everything went well, if a document was missing or there was an error, you would have to start over. Another businesswoman says that she sent the documentation online and when she went to do the process it took her only 15 minutes to get the permit. Land of entrepreneurship. That this reform has been promoted in Zhejiang is no coincidence. It is the province in which Hangzhou is located, the city that has become the reference technological hub for AI companies. Here you can find Alibaba, DeepSeek, Unitree or Deep Robotics. It is also where the Zhejiang Universitynicknamed “the Stanford of the East”, and where many of those who are today senior executives of technology companies have studied. The streamlining of bureaucracy is one of all the measures that the government has implemented and which also include very advantageous loans for entrepreneurs. One person companies. Recently We were talking about ‘one person companies’ or OCP and how the Chinese government is supporting this new entrepreneurship model. They are startups created by a single person with strong AI support, very much in the style of what he did Peter Steinberger with OpenClawwhich in turn has allowed many entrepreneurs to create their own solo companies. OCP communities are being created in cities like Suzhou, Wuhan offers special loans for ‘solopreneurs’ and in Shanghai they cover up to 300,000 yuan in computing expenses. How is it here? In Spain we also have our own agile business creation system called CIRCE. It works through the DUE (Single Electronic Document) that groups up to 25 administrative forms into one. Through CIRCE you can create or cease a company, whether it is a SL or a self-employed person, and it can take from one to ten days. Of course, for SLs it is still necessary to complete an in-person procedure at a notary office.

An alliance between Ford and Geely sounds like melodic music for Almussafes. The reality is much more complex

by

Ford is looking for a Chinese car. Reason: here. This is the sign that could hang on the door of the Ford factory in Almussafes (Valencia). The American company is looking for partners in China to produce electric cars and Geely seems to be one of the best positioned brands. Nor is it the first that has raised rumors about possible collaborations with the American brand, which, in addition, is already linked to Volkswagen or Renault. But what does Almussafes have to do with all this? Ford and Geely. The last brand with which Ford has been related in recent days has been with Geely. According to Reuters, Ford and Geely, Chinese group that owns Volvo, Polestar or Smart, among othersare holding talks to produce cars in Europe in one of the spaces that the company has on our continent. In addition, collaboration is being studied for the development of shared technologies such as autonomous driving. In Reuters They point to two sources who were aware of this information and the company has not denied that this is happening. “We have conversations with many companies about many things. Some are fruitful and others are not,” the Americans assure the news agency. For its part, Geely has not commented. Ford moves. It is not the first time that the company has been related to a Chinese company. On this occasion, it is said that negotiations have been underway for months and that Ford would have sent workers to the Asian country to advance a hypothetical agreement. Coincidence or not, Jim Farley has been traveling in China recently and He has been complimenting Chinese manufacturers for a long time. One of those companies that he has complimented and with which it has also been related It’s Xiaomi. Farley himself took a Xiaomi SU7 to the United States and has not failed to point out all the good things this product does. The collaboration agreement, it seems evident, would be for Europe since Chinese cars have an almost impossible future in the United States as a consequence of the Government’s own veto. Why Geely? The conversations with Geely seem to have much more substance than the possible collaborations with Xiaomi. The automobile conglomerate has brands that are not unknown to the European public (Volvo, Lotus, Smart…) whose electric cars do not have to break that barrier of entry into the European collective imagination as a “Chinese car.” However, Geely has a problem: they pay a lot of tariffs. As many as 37.6% after The European Union will withdraw in 2024 to try to protect an industry that was threatened by cheaper electric cars. Since then, the impact of the Chinese car has been limited to the lowest priced units. And it doesn’t seem like it’s going to change whether the negotiations between the European Union and China They still don’t get ahead. Collaborating with Ford and using the company’s facilities would allow Geely to produce electric cars without going through the checkout. And although labor costs are higher than the Chinese, they would not have to build new facilities because they would take advantage of those that the company has already built. Almussafes? In the information of Reuters It is assured that “Ford’s plant in Valencia would probably be the factory involved in these talks, said a person familiar with the matter.” However, some details must be taken into account. The factory is running right now at half throttlewith a Ford Kuga that is facing its last days on the market and that is not going to be renewed. The promise is to produce a multi-energy vehicle small size until 2028 when an electric car should arrive. To do this, the plant would need a deep reconversion that Ford is reluctant to carry out because North Americans are obtaining very low sales with their electric cars. A solution, therefore, would be to reach an agreement with Geely so that the Chinese company would take advantage of these facilities by making the appropriate conversions. The only doubt is that, right now, the plan is to produce a small model with a combustion engine. Electrifying space can put in check this multi-energy car that Ford should start producing soon. For now, the newspaper Levant reports that the brand will send a Ford delegation in the coming days to speak with those responsible for the factory. Ford’s mess with the electric car. Little by little, Ford has been falling into a small hole with the electric car which has a complicated solution. The brand has decided that its future lies in two clearly differentiated family lines: one made by themselveswith the Ford seal as quality and names clearly differentiated from the rest of the range (Mustang or Bronco) and lower cost cars manufactured by third parties. Europe is heading towards a future where the electric car seems the only solution. Until now, Ford’s investments have fallen on deaf ears and that is why it has reached a agreement with Volkswagen which has borne fruit electric Ford Explorer and the Ford Capri. And it has also signed an agreement with Renault so that the French can produce them in France. a sort of Renault 5 and Renault 4 with the blue oval. Ford promises that the cars will have their own American essence. At the same time, Ford focuses its own models on high-priced combustion or electric vehicles, such as the Mustang Mach-E. This allows them to achieve higher profit margins and bring combustion models to Europe in dribs and drabs whose high price justifies the increase in the final volume of emissions to be presented to regulators. What are the exits? At the moment, the first information points to different exits in the event that the negotiations between Ford and Geely come to fruition. First, it must be taken into account that what Geely may be most interested in is a car factory capable of producing electric vehicles as quickly as possible. Ford has a … Read more

Washing chicken “to clean it” sounds hygienic. Science says it’s a bad idea (and very dangerous)

by

“Chicken should never be washed.” This time, it was Higinio Gómez (one of the most renowned gourmet polleros in Spain) who reopened the debate in an interview in El País. But the issue is recurrent and inexplicably generates very opposing positions: from those convinced that washing chicken is a way to “remove germs or dirt” to those who, rightly, say that it is a terrible idea. But, as Gómez himself would say in his establishment, ‘let’s go in parts’. What’s wrong with the chicken? Let’s start with the most basic: nothing happens to the chicken. The risk linked to ‘washing chicken’ has nothing to do with the chicken itself. It has to do with cross contamination: the bacteria from raw chicken (which would be eliminated during preparation) transfer to the hands, sink, countertops, and various utensils. Often, in fact, when washing chicken we end up putting those bacteria in foods that are ready to eat. The EFSA estimated in billions of euros annually the impact of pollution Campylobacter (a bug especially linked to chicken). Sometimes it’s because you cook it wrong, yes; but often it is due to handling raw food without any type of rigor. What the evidence says. In a now classic observational study by the North American USDA, was discovered that, in fact, what I just explained was what really happened: among those who washed the chicken, 60% contaminated the sink and up to 26% ended up transferring bacteria to the salad. And, in fact, we already have experimental studies that explain the mechanism: beyond the obvious, “washing generates droplets capable of transferring bacteria and increasing environmental pollution” And why do people insist on washing it? That’s a good question with numerous answers: from the cultural and historical heritage (after all, when the chicken was slaughtered at home, washing did make more sense) to a lack of sense of control that ends up turning against us. Let’s be practical: How to avoid cross contamination when cooking chicken? Separate raw chicken from other foods: It is a good idea to keep the chicken raw separated from other foods. This is always true, but especially with all those that are consumed raw (such as fruits and vegetables). Use different utensils: We have talked about it with the cutting boardsbut it is especially effective advice with knives and other utensils. In fact, the recommendation is that, if we do not have several sets of utensils, wash them carefully between uses with hot water and soap. Wash hands and surfaces thoroughly: After handling raw chicken, you should not only wash your hands with soap and hot water for at least 20 seconds; Instead, we should disinfect all surfaces with which it has been in contact.

Reopening nuclear power plants sounds very spectacular, but Google has a plan B in case it’s not enough: solar energy

by

Data centers for are insatiable monsters those who are responsible for them must feed. OpenAI, Meta, Microsoft, xAI, Anthropic and Google are burning money riding colossal data centers for training and management of artificial intelligence. But these installations are not expensive to set up: they are also expensive to maintain. They require a considerable amount of energy to functionand Google has just received a ‘shot’ of renewables. All thanks to a direct connection to the largest system in the United States. Renewables to power AI. Google and TotalEnergies have just signed a agreement of energy purchases for 15 years. The contract stipulates that the energy company will deliver 1.5 TWh of electricity from its Montpelier solar plant, in Ohio, to Google. The plant is still under construction and they estimate that it will have a capacity of 49 MW, but the most important thing is that it will be connected directly to the electricity system. PJM. It is the largest network operator in the United States. It covers 13 states and data centers are representing a relevant portion of the operator’s pie: in its last annual auction, the load of these facilities PJM capacity sale triggered at 7.3 billion dollars, 82% more. Astronomical needs. In the statement from TotalEnergies, the company that this agreement illustrates its ability to meet the growing energy demands of the major technology companies. The problem is that it is not enough. If we focus on Google, the consumption of its data centers was 30.8 million megawatt hours of electricity. The company has been focused on AI for years, but the recent ‘boom’ has made it double what its centers consumed in 2020 (14.4 million MWh). Currently, data centers are estimated to account for 95.8% of Google’s total electricity budget. But it’s not just Google: the International Energy Agency esteem that global data centers consumed 415 TWh last year, representing approximately 1.5% of global electricity consumption. It seems little put in percentage, but Spain consumed in 2024 231,808 GWh, or 231 TWh, in 2024. The data centers of a handful of companies alone consumed twice as much as an entire country. And the estimate is that this data center consumption will double by 2030, reaching 945 TWh. Renewables are not enough. Now, although renewables are a support for the total energy required by data centerssolar and wind power have two limitations: intermittency and variability. Generation depends on weather conditions and time of day, meaning it fluctuates dramatically even throughout the same day. This instability clashes head-on with the high reliability and availability requirements of data centers. These are installations that must operate continuously and cannot assume cuts or Unforeseeable drops in supplysince AI or cloud storage would suffer the consequences. These renewables require backup batteries, but it is complicated and expensive to have such a large number of batteries just to power data centers. Pulling the gas and looking at the nuclear. That’s where other sources come into play. On the one hand, nuclear. In October 2024, Google signed the world’s first corporate agreement to acquire nuclear energy from SMR reactors. The first will come into operation in 230 and it is expected that, together, they will be able to satisfy the technology company with 500 MW of capacity by 2035. On the other hand, natural gas. In October of this year, the Broadwing Energy Center project began, a new natural gas power plant that will have a capacity of 400 MW and is scheduled to come into play at the end of 2029. Decarbonization and pressure. And the big question is… doesn’t the use of gas for AI clash with the technology companies’ objectives of achieving decarbonization percentages for both 2030 and 2050? We have already seen that oil companies have been getting off the renewables bandwagon because they have seen that fossil fuels are still relevant in the technology industry, but in the case of Google, they rely on the fact that projects like the Broadwing Energy Center They will have CCS systems. This means that it will have carbon capture system that will be able to permanently “sequester” 90% of the emissions. It means burying the problem, literally, since the CO₂ will be stored a mile underground. In 2020, before the AI ​​boom, the company established the goal of operating with carbon-free energy 24 hours a day, seven days a week by 2030. It will be interesting to see how they plan to offset these emissions thanks to renewables, but the IAE estimates that the demand for data centers will not stop growing in the short term and that adds another problem: a increased pressure on the electrical grid which is added as another element to manage. Because the big underlying problem is that the demand for energy is growing at a faster rate than the capacity to generate new electricity, and it is something that has an impact on companies’ bills, but also in homes.

The largest nuclear power plant in Europe has been connected to diesel generators for a month. It’s as encouraging as it sounds.

Europe is once again walking a nuclear tightrope. After more than three years of war, the largest atomic plant on the continent —the Ukrainian Zaporizhia plant— has gone from being an industrial symbol to becoming at a point of friction capable of triggering an emergency of continental reach. In parallel, other plants in the country operate at reduced power after attacks on the electrical grid. The situation is so unstable that the director of the International Atomic Energy Agency (IAEA), Rafael Grossi, recently traveled to Kaliningrad, Russia, for emergency talks with the head of Rosatom, Alexey Likhachev, according to the Anadolu agency. It is a gesture that reflects the extent to which the risk is real. An attack that left two centers at minimum. According to a statement from the IAEAa military attack during the night of November 7 damaged an electrical substation critical to nuclear security. This incident left the Khmelnitsky and Rivne plants disconnected from one of their two 750 kilovolt lines and forced the electricity operator to order a power reduction in several of its reactors. Ten days later, one of the lines was still out of service and three reactors continued to operate at limited power. The agency emphasizes that these substations are essential nodes of the network: they allow the voltage levels that feed the security and cooling systems to be transformed and maintained. Without them, plants cannot guarantee safe operation. One month depending on diesel generators. The situation in Zaporizhzhia is even more critical. According to an opinion column by Najmedin Meshkati, professor of engineering and international relations published in the Financial Timesthe plant spent a full month without outside power after its two main lines were cut. During that time it survived solely on diesel generators, a resource that the industry considers strictly temporary: they are designed to run for around 24 hours, not for weeks. Technicians were only able to repair the lines under the protection of localized ceasefires negotiated by the IAEA, according to NucNet. Even so, one of the two restored lines was disconnected again on November 14 due to the activation of a protection system. Grossi summed it up like this: “The electrical situation at the plant remains extremely fragile.” The condition for a shut down reactor to remain safe. Although Zaporizhzhia’s six reactors have been on cold shutdown for more than three years, the plant requires a constant three to four megawatts to maintain cooling pumps and other essential systems, according to Meshkati. The professor emphasizes that even huge emergency batteries require external electricity to stay charged. It is a vicious circle: without the electrical grid, batteries are used, but without external electricity, these batteries cannot be recharged and, without both, the cooling systems fail. And without cooling the risk of nuclear fuel melting or overheating increases. The University of Southern California professor warns that this scenario reproduces the conditions that transformed Fukushima into a global disaster: “What turned an earthquake into a catastrophe was the total failure of the electrical system.” And he adds that, unlike 2011 in Japan, this time the risk comes from deliberate human action. A network reduced to its minimum expression. Before the war, according to the Kyiv Independentthe Zaporizhia plant was connected through ten power lines. Today it only has one or two operations and has lost all connection ten times since the beginning of the invasion. The IAEA itself has described the situation power plant as “extremely precarious” and “clearly not sustainable” when it depends for long periods on diesel generators. Short and medium term risks. The notices in the last report on Ukraine by the IAEA point in the same direction: the main danger is not a Chernobyl-type explosion, but a prolonged cooling failure. This scenario could cause overheating of the reactors in cold shutdown, damage to the spent fuel pools and a possible localized or regional radioactive release, with the consequent need to create an exclusion zone in the heart of agricultural Europe. For its part, according to Meshkatiadds two other relevant elements. On the one hand, it points out that a serious accident will exceed the economic impact of Fukushima, estimated at about $500 billion. An incident of that magnitude would affect agriculture, transport, supply chains and the European insurance market. On the other hand, he maintains that if Russia manages to consolidate the precedent that an occupying army can take control of a nuclear power plant and connect it to its own network, the global nuclear security architecture would be seriously compromised. It would be a precedent without equivalent since the creation of international standards that regulate the civil use of atomic energy. Is there a meeting point? The IAEA has acted as an intermediary between Moscow and kyiv on multiple occasions. According to the Anadolu agencyGrossi traveled to Kaliningrad to meet with Likhachev, director of Rosatom, in order to directly discuss the situation in Zaporizhzhia and the minimum conditions to guarantee nuclear safety. At the same time, the agency is trying to technically shore up the Ukrainian electrical system. According to their own statementshas so far coordinated 174 deliveries of essential equipment – ​​switches, electrical cabinets, radiation monitoring stations, vehicles and computer equipment – ​​worth more than 20.5 million euros, intended to sustain nuclear security in Ukraine during the war. Nuclear security supported by fragile cables Europe breathes thanks to a handful of cables repaired under fire and diesel generators that have already proven to be well beyond their limits. As the Financial Times explainsthe continent’s security depends on electricity continuing to arrive and on the parties respecting the fragile ceasefires needed to repair lines when they go down. Grossi summed it up with a mix of relief and alarm after the restoration of one of the lines: “It is a good day for nuclear security, although the situation remains highly precarious.” And the precarious thing, in this case, is that a new attack, a mechanical failure or a downed line is enough to bring … Read more
