A Chinese laboratory has managed to generate electricity directly from rain, without occupying land or using metal

by

Until now, the electricity from a storm came only from lightning. A Chinese team has just added another protagonist: a device that converts raindrops into usable energy. The invention comes from the Frontier Science Institute of the Nanjing University of Aeronautics and Astronautics (NUAA) and will open a new avenue for renewable energies. Its technical name is Water-integrated Droplet Electricity Generator, or simply W-DEG. The discovery. What differentiates this generator from the rest is not its power, but its logic. According to the published article in National Science Reviewthe device floats on water and uses that same water as part of the electrical circuit. It requires no metals or heavy structures, and yet each drop of rain can release spikes of up to 250 volts. Light, cheap and efficient: a small hydrovoltaic revolution. Rain as a source of clean energy. The physical principle behind W-DEG combines two known phenomena: contact electrification and electrostatic induction. When a droplet impacts a floating dielectric film, electrical charges are instantly redistributed between the surface of the material and the water, generating an electrical pulse. Water acts at the same time as a lower electrode and structural support, thanks to its high surface tension and incompressibility: it is firm enough to withstand the impact of drops, but fluid enough to stabilize the system. To prevent pooled water from blocking new discharges, the researchers added micro-drainage holes that allow liquid to flow downward, but not upward. This design keeps the surface clean even during heavy rain and prevents loss of efficiency. A small prototype. The Nanjing team built a 0.3 square meter prototype. Floating on water, the device was able to illuminate 50 LED diodes simultaneously and charge capacitors in a matter of minutes. Its modular design allows it to be easily expanded to power environmental sensors, water quality monitoring systems or small electrical equipment in rainy areas. Furthermore, the W-DEG is a “soilless” system: it does not occupy agricultural or urban land and can be installed on bodies of water without heavy infrastructure. This makes it an ideal candidate for regions where rain is abundant and space is scarce, or where other renewable sources – such as solar or wind – are less constant. The rise of floating energies. The new Chinese generator arrives at a time when floating energy is experiencing a global boom. Floating solar panels are being installed on ponds and reservoirs around the world, from India until the swiss alpsto produce electricity and reduce water evaporation. However, a study from Cornell University revealed an unexpected effect: in small ponds, these installations can increase methane and carbon dioxide emissions by up to 27%, by altering the balance of aquatic ecosystems. Faced with this challenge, the W-DEG emerges as a more environmentally friendly alternative. By not covering the entire surface of the water or blocking sunlight, it allows energy to be generated without altering aquatic life or natural gas exchange. Will storms generate light? The technology is still in the experimental phase. The NUAA team itself recognizes that it will have to optimize the device’s response to droplets of different sizes and speeds, something essential for real conditions. But the potential is undeniable: a lightweight, economical and durable generator, capable of obtaining energy directly from the natural water cycle, without occupying land or generating waste. Researchers imagine swarms of these devices floating in lakes or reservoirs, charging environmental sensors or powering local microgrids during rain. If every storm could turn on a light or power a system, gray days would no longer be synonymous with a blackout. With inventions like this, the border between water and energy blurs, and nature begins—literally—to generate its own electricity.

The secret of Chinese AI companies to compete without Nvidia chips: electricity subsidized by Beijing

by

Everywhere we look, there is artificial intelligence. Everyone talks about it, but what is its fuel? It’s not the data or the chips: it’s the electricity. While in the West technology companies are looking for how to power their data centers —increasingly energy hungry—, China has decided to take a different step. Beijing has designed an energy subsidy for its technology sector with a clear objective: to make the energy that powers the digital brains of its next generation of chips cheaper. Energy subsidy. Since September, the Chinese Government banned large national technology companies —including Alibaba, ByteDance and Tencent—acquire artificial intelligence chips from the American Nvidia, in an attempt to strengthen local production. However, the consequence was immediate: national processors consume more electricity. According to The Chosun Dailygenerating the same number of tokens with Chinese chips requires 30% to 50% more energy than with Nvidia’s H20, which sent electricity bills skyrocketing and led companies to complain to regulators. To make up for that gap, local governments introduced grants that cover up to a full year of operating costs, according to the Hong Kong media on.cc. In those provinces, industrial electricity was already 30% cheaper than in the developed coastal areas of the east, but with the new incentives the price could fall to 0.4 yuan per kilowatt-hour, a record figure for the Chinese technology industry. ¿How does the energy plan work? The scheme is relatively simple, but strategic. Local governments offer electricity discounts of up to half to data centers that use chips produced within the country. Operators that use foreign processors – such as those from Nvidia or AMD – are excluded from the program. In addition, the energy provinces receive direct support from the State to finance the discounts, with the aim of reducing dependence on technological imports and compensating for the increased consumption of local chips. According to the Financial TimesChinese data centers that rely on domestic semiconductors are, for now, less energy efficient, but the subsidy seeks to bring their costs in line with those of more advanced foreign chips. These regions—Guizhou, Gansu, and Inner Mongolia—have become hotbeds for data center clusters, thanks to their abundance of hydropower and coal. There, companies like Alibaba or Tencent are building new facilities to house their generative AI models, taking advantage of lower energy costs and tax incentives. This policy combines three strategic priorities: making energy cheaper, promoting domestic chips and reinforcing technological sovereignty. In a context of United States restrictions, each subsidized kilowatt is also a political statement. An industrial policy with a geopolitical charge. Behind the energy plan is a long-range political commitment. The Chinese Government intends for its technology companies to progressively replace imported chips with domestic processors, even if this implies higher costs in the short term. The electricity subsidy acts as a temporary bridge for national giants to adopt local chips without losing competitiveness. This measure is included in a broader national strategy of technological self-sufficiency. As the Financial Times explains in its series The State of AIChina is using its “society-wide mobilization capacity” to accelerate the development of artificial intelligence. The country already leads the number of patents and scientific publications in AI, and although the United States maintains an advantage in chips and talent, the gap narrows every year. Analyst Dan Wang, quoted by the same media, points out: “China has achieved a unique balance between engineering capacity, state control and massive industrial deployment, allowing it to advance faster than other countries in the practical application of AI.” Meanwhile, in the West… China’s decision contrasts with the energy challenges of the United States. Microsoft CEO Satya Nadella warned that the real bottleneck of AI It is no longer the chips, but the energy. In fact, he explained that many companies accumulate chips that they cannot connect due to lack of power supply. Both Microsoft and Google are already studying building modular nuclear reactors to power their future data centers, a sign of the enormous energy consumption that artificial intelligence requires. While Silicon Valley seeks electricity, China subsidizes it. This asymmetry reflects two different models: one guided by state intervention and the other by market competition. Both pursue the same goal—sustaining the artificial intelligence revolution—but with opposite philosophies. A future plugged into the State. The Chinese subsidy not only alleviates costs: it redefines the relationship between the State and the private sector in the age of AI. As analyst Arnaud Bertrand observed, US restrictions pushed China towards a different model: more efficient, more open and more collective. “By operating under hardware limitations, Chinese companies have learned to optimize resources and share open models like Qwen or DeepSeek,” wrote Bertrand on the social network That strategy, based on efficiency and diffusion, could give China a long-term advantage in global adoption, since any company in the world can download and adapt its models. The country that controls the plug. China isn’t just making the chips that power its artificial intelligence. It is also building the electrical grid that makes them possible. In a world where data is the new oil, Beijing has decided to subsidize the fuel of the digital brain. While the West debates how to connect its supercomputers, China plugs them in at a reduced price. And in this race, whoever controls the plug could end up controlling the future. Image | FreePik and FreePik Xataka | The world of AI has a problem: there is no energy for so many chips

If you were expecting cheap electricity this winter, we have bad news: Holland

by

Winter has not yet arrived, but the European energy market has already started to shake. And not because there are new problems with Russian gas pipelines. The winter that awaits us. The warning he issued the analyst Pedro Cantuel illustrates the problem: “The most important regasification plants in Europe, those in the Netherlands, are operating at maximum capacity.” It is not a positive fact. These terminals are the main gateway for liquefied natural gas to the industrial heart of Europe. Its saturation is the prelude to higher gas prices. And gas is what marks the electricity bill in much of Europe. And the Spanish regasification plants? Although Spain has the largest regasification capacity in the European Unionwith six active terminals, its ability to alleviate Europe’s thirst for gas is limited. The problem: the poor gas interconnection with France. The current bottleneck of the Pyrenees It barely allows the export of between 7,000 and 8,500 million cubic meters per year. Therefore, all eyes are on the Netherlands. Its terminals, mainly Gate’s in Rotterdam and Eemshaven, are the true entry point for Germany and European industry. In figures. Netherlands is the main LNG importer of the EU. Between June and August 2025 alone, it regasified more than 2,000 million cubic meters of gas. But according to the data of Gas Infrastructure Europeits terminals are constantly touching the all-time high. The Dutch ports are saturated, there is no more LNG. And this has a direct effect on Germany, which since the sanctions against Russia imports 25% of the gas from the Netherlands. With the terminals of the neighboring country at 90-100% of their capacity, the room for maneuver due to a peak in demand due to a cold wave or any delay of a LNG tanker will immediately strain the system. How it affects the invoice. As we have seen in recent years, any difficulty in accessing natural gas results in higher prices. The Agency for the Cooperation of Energy Regulators documents in your reports a direct correlation between the high utilization rates of LNG terminals in northwest Europe and the increase in volatility and spreads (price differences) in the gas reference index in Europe. We have changed dependence on a single supplier (Russian gas pipelines) for dependence on a single infrastructure that can now become the new bottleneck has moved from the gas pipeline to (European ports). Efforts are already underway to expand port capacity. Gate, for example, is building a fourth tank to reach 20,000 million cubic meters per year. But it won’t be ready until 2026, so the reality for this winter is what it is: the system is operating at the limit of its capacity.

Clean energy has made the electricity market cheaper. But what we pay for is no longer energy: it is stability

by

Spain is a unique case in Europe: it has managed to ensure that gas and coal barely influence the wholesale price of electricity – only 19% of the hours this year, compared to 75% in 2019. according to a report by Ember. Thanks to this, the average Spanish wholesale price was 32% lower than the European one. However, something does not add up: the consumer still paying an expensive billwhy doesn’t the receipt go down? Let’s go in parts. Since 2019, Spain has added more than 40 GW of new solar and wind capacity, doubling its renewable power. In the first half of this year, 46% of the electricity generated was clean. But on April 28, 2025 came the blow of reality: the great blackout. A concatenation of electrical failures and lack of operating margin left much of the country in the dark for hours. The ENTSO-E preliminary report discarded that renewables were the direct cause, but it did reveal a structural problem: the Spanish network was not prepared for so much intermittent generation without sufficient flexibility. Since then, Red Eléctrica operates the system in “reinforced mode”activating more combined gas cycles to stabilize the voltage. According to Emberthat strategy has come at a high cost: in May, gas-based network services represented 57% of the final price of electricity, compared to the usual 14% before the blackout. The underlying problem. Spain produces more clean electricity than ever, but cannot fully take advantage of it. The lack of grid, storage and interconnections is leaving thousands of solar and wind megawatts unused. Although there is now a plan in place to reinforce those connections that act as a bottleneckthe reality is that when there is excess clean energy and it cannot be exported, it is “thrown away”. He curtailment (wasted renewable energy) has tripled since the blackout, going from 1.8% to 7.2%, according to Ember. Furthermore, the country continues to lag behind in flexibility. Regarding investment in batteries, it arrives late: Spain is placed in fourth position in the electricity market, but it is thirteenth in batteries, with only 120 MW installed. Despite to have planned a total of 16,000 MW planned for 2030. The reason for these problems is structural and can be understood with the investment made in networks of such only 30 cents For every euro allocated to renewables, half the European average. In other words, we have more sun than cables. The cost of fear. The problem is not only technical, but economic. As the analyst Javier Blas recalledoperate in reinforced modeeither since April it has cost consumers an additional billion dollars. And that is just the beginning: the approval of the new re-reinforced mode could add another 3,000 million euros and open the door to increases in fixed rates by the marketers, as the UNEF has detailed in statements to El Español. The cost of keeping the network “in tension” is transferred directly to the invoices, even if the wholesale price is low. Ember’s own report points out that the wholesale market price It only covers approximately half of the electricity bill, the so-called “energy component.” The rest – networks, tolls, taxes, stability of the system – does not decrease even if electricity becomes cheaper at source. Therefore, falling wholesale prices do not automatically translate into lower bills. The ghost of the blackout again. Six months have been enough for another feared blackout to return. Red Eléctrica warned of “sudden voltage variations” in the peninsular system, so serious that it asked the CNMC for permission to urgently modify several operating procedures. Among the measures: more room for maneuver to act before the operating day begins and stricter control of reactive voltage. An express adjustment of the country’s electrical operations to contain the ups and downs of voltage, just as my partner described. The REE itself insisted that “there is no imminent risk of a blackout,” but the truth is that no one is calm. “The grid operator has been operating in reinforced mode since April 29, activating gas plants with greater intensity and reducing solar and wind energy,” Blas pointed out. Every day that passes in these conditions adds costs that end up being passed on to customers. The ghost of the blackout is still there: less visible, but more expensive. From patches to clean flexibility. After the blackout a reform package was approved (Royal Decree-Law 7/2025) with measures to strengthen the network and promote storage. Although the decree was rejected in Congress, many of its provisions are being applied in other ways. Among them, the installation of eight synchronous compensators stands out—devices that stabilize voltage without using fossil fuels—and a portfolio of 2,600 MW of batteries, of which 340 MW already have permission. From Ember has been calculated that the compensators will involve an investment of 750 million euros, but will save 200 million a year by reducing the use of gas for network services. The objective is clear: to move from gas as a crutch to clean flexibility as the basis of the system. The Spanish paradox. Spain is Europe’s energy laboratory: the country where renewables have shown that they can reduce the wholesale price, but also where it is clearer to see how expensive it is to sustain this transition without robust networks. As explains Ember’s reportaround 50% of the Spanish electricity bill corresponds to the energy component, which has become cheaper. The rest are system costs and from there, although the megawatt-hour does not cost less, the final bill barely goes down. A major challenge. Spain has shown that it can have the cheapest electricity in Europe and, at the same time, one of the highest bills.Because the energy transition is not measured only in megawatts or solar panels, but in cables, stability and trust. The challenge now is not to produce more clean energy, but to make it arrive—and be paid for—fairly.

There is more renewable electricity in the world produced by coal

by

Ten years ago, coal lit half planet. Today, it is solar panels and wind turbines that illuminate statistics. In the first half of 2025, the renewables not only covered all the increase in global electrical demand: they exceeded it. A global sorpasso. The report, prepared by Emberanalyze data from 88 countries that represent 93% of global electric demand. Its conclusion marks a before and after: solar and wind energy grew so much that they compensated all the increase in global electrical consumption and still generated surplus. However, there is an even more important point that is that coal generation fell worldwide. Carbon participation fell to 33.1% of global electric mix, while renewables rose to 34.3%. For the first time, the coal was behind. The descent was especially clear in China and Indiawhere coal has always dominated and, therefore, that descent is noted. On the other hand, both in the European Union and in the United States a small rebound was observed, caused by hydroelectric drought and the Gas increase. Renewable energies produced more electricity than coal for the first time recorded in the first half of 2025 | Ember Radiography of the change. The transition is not a statistical anecdote, but a structural phenomenon. World demand increased 369 twh (+2.6 %), moderate growth that was widely covered by solar and wind expansion. On the one hand, the sun remains the most dynamic source on the planet. The solar generation grew 31%, reaching a global quota of 8.8%. However, this is because China It was the great enginecontributing 55% of world solar growth, followed by the United States, the European and Indian Union. On the other hand, the wind keeps the pace. The wind generation increased by 7.7%, to represent 9.2% of the global mix. Although Europe and the United States suffered adverse weather conditions, China increased, registering a 16% increase in their wind production. The money also changed sideways. The other great indicator that this change is structural is in the markets. According to the International Energy Agencythe global investment in energy will reach 3.3 billion dollars, a fairly striking figure. Only ten years ago, renewables were seen as An idealistic bet: faces, intermittent and subsidy dependent. Today they are the new center of financial gravity of the energy system. The proportion of clean investment against fossil went from 2 to 1 in 2015 to 10 to 1 in 2024, a change that reflects a collective market decision. However, not everyone is invited to the party. Emerging markets and developing economies barely receive 15% of world investment In clean energy, despite the fact that its electric demand is the one that grows the most. In addition, they are still trapped between high financial costs, fragile networks and regulatory uncertainty. As Ember warnswithout international financing and technological cooperation, the global rhythm towards zero net emissions could be stopped before achieving the objective. China drives the global transition. Behind the world sorpasso there is an undisputed protagonist: China. Not only leads the production of clean energy, but also the industry that makes it possible: panels, turbines, batteries and smart networks. Its industrial policy has made the country what some analysts describe as an “electrostate”capable of dominating the energy value chains of the 21st century as it dominated the manufacturing. In just six months, China installed 380 GW of new solar capacity – more than all the total capacity of the United States – promoted by a wave of projects prior to new price standards. Thanks to this, its mixture Electric is already renewable 24%, and the emissions of the electrical sector fell 1.7% in half a year. Global challenges. According to Emberthe electricity grid is already the main obstacle to renewable expansion. Solar and wind production increases faster than lines and storage grow. In countries such as Spain or Germany, specific cuts have been registered in solar parks by network saturation. In Japan, operators reduce solar generation on weekends to avoid overloads. This forced disconnection –The call Curtailment– shows a paradox: we have more sun than cables. To the saturation of the networks is added the inequality of access to capital. While China and other economies install renewable gigawatts every month, Africa and Latin America are still waiting for sufficient investments. Hence the urgency of new global mechanisms to channel green capital towards emerging economies and ensure that the transition is truly global. An irreversible turning point. Just a decade ago, coal generated twice as much electricity than renewables. Today, clean energy has surpassed the most polluting source and dominates the growth of the electrical system. China leadsIndia accelerateEurope It adapts and the United States It stops. Prices fall, investments grow and emissions begin to stabilize. The energy transition is no longer a matter of political will: it is an economic law. The turning point is not in the future: it is happening right now.

The brands are turning in the electricity. Porsche and Audi will return to combustion because nobody wants to buy them

by

We do not know the future and that encourages us to be anchored in the past. The electric car brings more power and greater control over it, a wilder acceleration or cars that will end up being more effective in curve. With the weight of the current sports, it is not surprising that we begin to see very similar figures in weight … and much better if we talk about the weight/power relationship with respect to the combustion models. Byd, in fact, has just demonstrated that The future of the hyperdeportivo is electricsweeping Bugatti and becoming the Yangwang U9 in the fastest car in the world. A long time ago, the McMurtry Spéirling I left ridiculous The acceleration of any car with combustion engine. And, despite everything, the sports electric car is still not pending. We do not know if it is a matter of time, if cars like the future RENAULT 5 TURBO 3E They will break schemes and become an immediate classic. But until then, the combustion car offers sensations that the electric car cannot match. For some those Sensations They are different. For others, they are clearly better. Anyway, there is evidence: the sports electric car does not finish convincing. And that is causing the plans to electrify these models are delayed. The best example is the future Porsche 718. A car that had to make the leap to the electric whole and that, however, will have a version of combustion. And that, with rebound, will lead us to a future Audi Deportivo that will also mount combustion engine. Porsche collects cable (and passing, Audi benefits) “We want to meet the new market realities and change customer demands. We have seen a clear drop in the demand for exclusive battery electric cars, and we are taking it into account.” The words are from Oliver Blume, CEO of Porsche, in a call to investors collected by The Autopian. They arrive to confirm a change of strategy. Future Porsche 718, classic central motor sports and the entrance range to the company will continue to offer, at least in their most expensive options, combustion engines. The news is the confirmation of what began to be an open secret: the future Porsche 718 will not be only electric as He had defended until now by the company. The movement arrives just when it is also confirmed that the Porsche Cayenne will not jump into the electrical exclusive. It is a strong change in strategy since The good initial results of the Porsche Taycan They had served the Germans to boost their electrical strategy. However, China has turned its back on the company And it has broken much of this strategy. Along the way he has confirmed that wealthy customers who have access to their combustion cars … They are not making the jump to the electric. So much so that the Porsche Macanwhich was sold as an exclusively electric model, could have a combustion brother in 2028 according to Jalopnik. Of course, we will have to see on what basis because The PPE on which the macan sits Current only admits completely electric models. When we analyzed the new Porsche Macan Electric we already counted that it was a really interesting car. It was an effective car, a brute force and a surprising curve step for its height and size. But he had a but: That car had a V6 gasoline engine before. And convince who enters the world Porsche that now that engine is electric … is very complicated. The basic problem for Electric Deportivo is that cars are much more than numbers. In social networks it is repeated as a mantra that “Who knows how to handle an Excel buys an electric car”. And yes, it’s true If you are looking for a “affordable” car for day to daywith a lower expense in “fuel”, a savings in maintenance over the years, tax benefits in taxes … But none of that is taken into account when one buys a central motor biplaza. That is why a Mazda MX-5 continues to transmit sensations that no other car transmits with just over 100 hp. That driver profile values ​​the sound of the car, the thrust when it goes up or the touch of a manual gearbox. Yes, a quartz clock is usually more precise than automatic but the buyer values ​​the “artisanal” work under the sphere. Yes, a digital camera is more versatile and easy to use than an analog but the Feeling To load the reel and “feel” the mechanics in the hands goes far beyond the megapixels. These cars are mere whim toys And, as such, they do not attend to rational factors. You can talk about numbers but that is only the continent, not the content. Given this diatribe, the brands that are indissoluble of this driving experience have it hard complicated. Especially those more “earthly.” Ferrari either Lamborghini It has a higher bandwidth to transfer to its customers the possible fines that reach it in the future, Porsche does not have so much room to transfer this cost to the customers. Especially in the most “affordable” models. That is why a two -speed future has been raised. It is no accident that Combustion models of the Porsche 718 are identified with the top range versions. That will help sell the most expensive versions because they will deliver a inaccessible driving experience for the vast majority of drivers. But, it will even be relatively inaccessible even for those who can buy a Porsche. This future Porsche 718 gives the company air. As they explain in The cars.net podcast Joan Dalmau and Juan Carlos Grande, companies have made efforts to advance a solid range against a horizon in 2035 without combustion engines. But they need to continue earning money and in Europe the client has not embraced the electric car at the expected rhythm. In this business niche, problems are even more serious because, as we said, rationality is … Read more

The most powerful countries and with greater electricity consumption per capita, ordered in this graphic developer

by

He Electric consumption It is a great thermometer for countries. The amount of energy we consume is an economic, but also social, climate indicator, of technological decisions and even lifestyle. The reason is that there is a wide range of factors that influence this consumption, and the following graph prepared by Visual Capitalist We can see what are the 15 countries with the highest GDP in the world which consume more electricity per capita. The surprise is called … Canada. Oh, Canada. The data comes from Ember and reflect the difference between the consumption of electricity per capita of the main world economies In 2024 and the one they had in 2000. A quarter of a century is more than enough to see a change in this regard, but what has not varied an apex are the two nations that lead the graph. Canada occupies the first position with consumption in 2024 of 15,708 kWh per person in 2024. The figure is considerably less than the one that registered 24 years ago and that high consumption is driven by an industry (especially mining and Aluminum production) very demanding at the energy level and for the electricity necessary to withstand the long winters. The United States, with 12,741 kWh per person, is not behind and the reasons are very similar: industry and air conditioning (which is at an excessive temperature both in winter and in summer). South Korea and China. Australia is another of the countries that traditionally exceeded 10,000 kWh per person, but these last 24 years have passed something curious: South Korea has glued a time comeback in this indicator. Here we enter that of electricity consumption as an economic thermometer, by relating the passage of the 6,200 kWh at 12,100 kWh due to an advance in advanced industrialization and manufacturing, especially in the segment of semiconductors and cars, as well as the growth of data centers. In China we live a very similar phenomenon, with a consumption of about 1,100 kWh in 2000 and one of 7,100 kWh currently due to that same technological expansion with the Accelerated industrialization in steelaluminum, electronics, data centers, semiconductors and electric vehicles as main protagonists. In addition, even if it is practically half of the per capita consumption of Canada, we are talking about a population of 1,400 million people compared to about 40 million. To put it in percentage: 17% of the world population compared to 0.5%. Logical. But the increase in consumption in these two countries is not only due to industrialization. Japan also has a strong industry and consumption has remained practically identical. There is another factor: The increase in middle classespecially in China. The increase of living standards, urbanization and electrification in homes has contributed considerably to this increase in consumption. Migration to large cities has generated a boom in construction and electrification due to the use of appliances, services and goods such as electric cars. Now, that is causing other problems, such as a life train incompatible with the formation of families wave Lack of people working in factoriesbeing two of the Shared problems with their neighbors Japan and South Korea. Two prominent outside the graphic. Germany, Spain and Italy have consumption very similar to those of 25 years ago, but if we look beyond this classification for the 15 main world economies, we have two names that eclipse everyone else. On the one hand, Iceland, with an imposing consumption of 51,920 kWh per person, thanks to the fact that there are not many Icelanders (about 300,000), but they do have A very potent industry such as aluminum, as well as very few hours of light and an extreme climate that requires constant lighting and heating. In Norway they also put the heating and light the lights, they also have an industry and a high standard of living that allows high consumption, but something that helps its consumption of 24,580 kWh per capita is a tremendous electric car park. In fact, in 2024, Almost 90% of the new cars sold were 100% electricwith what this entails at the charge level both at home and in public networks- In Xataka | This chart exposes self -sufficient countries at the food level.

A Microsoft Data Center in Mexico collided with the reality of the electricity network. Your solution: use gas generators

by

Artificial intelligence has become daily, but behind each consultation to tools such as Chatgpt either COPILOT There are real buildings that consume a lot of energy and require reliable infrastructure. In that framework, Microsoft announced May 7, 2024 The beginning of operations of its “Central Mexico” data centers region, with several locations in the Querétaro Metropolitan Area. The deployment, however, coexists with very specific tensions: According to the companyat least one of those centers, that of Columbus, cannot benefit from the advantages of the electricity network until mid -2027 and obtained permission to temporarily operate with gas generators. It should be remembered that the proximity of these infrastructure to users is essential: it reduces latency, improves the quality of the service and allows to meet data residence requirements. But that technical advantage depends on something elementary: having an electricity grid capable of sustaining permanent operations and constant cooling. Microsoft stressed the magnitude of its project in the North American country. The new region aims to offer local access to Azure, Microsoft 365Dynamics 365, among other services. The firm also presented the initiative as an “avant -garde” infrastructure aimed at accelerating innovation in the region. The Achilles heel of deployment: energy In a request to the Ministry of Environment delivered in 2023Microsoft acknowledged that, although the data center would connect within the planned deadlines, due to the construction deadlines included in its contract with the Federal Electricity Commission, the energization of the connection would not be ready until the Second quarter of 2027. To save that void, The use of seven generators was approved capable of covering 70% of the demand of the center of Columbus for 12 hours a day, for at least four months. According to Rest of World, Mexico already has about a hundred data centers, with investments that exceed 7,000 million dollars from 2020 by Microsoft, Aws and Google. Querétaro has established itself as the main attraction pole, with 15 facilities that concentrate about 80% of the sector’s energy demand, about 200 MW. The Mexican Institute for Competitiveness projects thatby 2030, the network will face a deficit of 48,000 MWh, more than half of what it produced in 2023. With more than 70 new centers planned in the next five years, the mismatch between installed capacity and electric transmission becomes an obvious threat. The American company has set ambitious environmental goals: Being negative carbon in 2030, eliminating all its historical emissions in 2050 and supplying 100% with renewable energy contracts in 2025. In contrast, in Columbus is the provisional measure of operating with gas generators until it can be fully connected to the network in 2027. What It is not clear is whether these equipment were usedif they remain in operation or what intermediate solution the company will apply in the coming years. Microsoft, for now, has not specified with which energy sources Opera Colón. The launch of the Central Mexico region was presented as a decisive step to accelerate the country’s digital transformation and attract foreign investment. But energy reality introduces a decisive nuance: the infrastructure necessary to sustain that deployment does not advance at the same rate as the technological ambition. The tension between promises of sustainability and limitations of the network is a reminder that the cloud, far from being ethereal, rests on concrete foundations, cables and megawatts that define, in a way, how far artificial intelligence and other services can go.

99% of the Internet travels through submarine cables. Now there is a much more ambitious plan in progress: join the electricity grid

At first glance, the seas are an empty landscape. Under its waters, the image is another, through it a network of invisible highways that already support our day to day: the submarine cables that carry the 99% of world communications. Now, a new generation of electrical interconnectors – thousands of kilometers and gigavatio power – aspires to bring sun, wind and hydraulic where they are missing, when they are missing. The promise is simple: that electricity travels with the sun and wind through schedules; The execution, not so much. The starting point: The North Sea. The United Kingdom and Denmark premiered at the end of 2023 the Viking Link, a 765 km cable that crosses the North Sea and allows you to import electricity when wind is missing on the island and export when left over. It is the longest interconnector in the world in operation, but, as Financial Times warned: “It may not be for a long time.” The British media report details That on the horizon there are much more ambitious plans: join Canada with the United Kingdom and Ireland through a 4,000 km cable, link Morocco with Europe or export Australian solar energy to Singapore through more than 4,300 km of submarine cable. Through the cables. This new megaproject makes it clear that countries have been pursuing a connection with renewables for some time, because there is a mismatch between production and consumption, and we must solve it. The most illustrative example is AapowerLink in Australia. The Suncable company plans to install 3 GW from Solar in the northern territory, store part in batteries and sell it both to Darwin and Singapore, through an underwater cable of more than 4,000 km. In the words of his CEO, Ryan Willemsen-Bell, collected by Financial Times: “Australia has abundant land and sun. The ability to share those benefits with our neighbors has enormous potential.” In parallel, the North Atlantic Transmission One Link seeks to connect the Canadian hydroelectric plant with Europe. The time differential is its great asset: when Canada sleeps, the United Kingdom starts the day; When in the North Sea, wind blows at midnight, New York is preparing dinner. A lesson from the Internet. The idea may sound futuristic, but there are already solid precedents. As we have underlined Xatakathe entire planet is furrowed by submarine data cables, authentic digital highways that have demonstrated the viability of infrastructure of tens of thousands of kilometers. The Southern Cross Cable Network, 30,500 km, connects Australia, New Zealand and the United States since 2000. The newly opened 2Africa, 45,000 km, surrounds the African continent and reaches Barcelona and India. And in Spain, cables such as tide (6,605 km, Meta and Microsoft) or Grace Hopper (7,191 km, from Google) link Bilbao with the east coast of the US. The experience of these data networks provides an obvious parallelism: if we already move information on a global scale, why not also clean energy? Although not everything is so easy. From Financial Times alert a tensioning supply chain: The manufacture of cables, transformers and converting stations does not supply. The waiting deadlines are lengthened, and the availability of specialized ships to tend cable is limited. To that are added political risks. In Norway, the export of electricity to its neighbors has triggered the internal debate on prices. In the United Kingdom, the Government rejected this year to support the X-Links project to bring energy from Morocco, claiming “high level of inherent risk”. And with the ongoing Ukraine War, the threat of sabotages to critical infrastructure It is a fact. Looking inside. In the Spanish case, the problem is more domestic than international. As we have explained in Xatakathe country has run more than anyone to lift renewables in the “emptied Spain”, but has not deployed the cables to bring that electricity to the cities. The result is a “broken bridge”: at noon there are plenty of cheap megawatts that are cut or sell at zero price, and at night the network needs gas support, more expensive the market. According to data from the AELēC employer, 83.4% of connection knots are already saturated, which prevents hooking new consumptions such as industries, data centers or electrolyiners. The challenge, in short, is not to plan and reinforce the networks; as well as improve interdependence with other countries to break With the French bottleneck. A map of interdependencies. Beyond the technical and economic, these electric highways draw a new geopolitical map. Just as pipelines and gas pipelines marked the twentieth century, renewable interconnections can define alliances and dependencies in the XXI. The engineer Simon Ludlam, co-founder of the Canada-UK project, summed it up in Financial Times: “The most important nuclear reactor is in heaven, and its energy can be shared thanks to the rotation of the earth. But we need to be interconnected.” The sun that shines in the Australian desert or the water that falls in Canada could light, in a matter of seconds, the lights of cities to thousands of kilometers. The energy transition not only depends on producing renewables, but also on learning to move them. If the pipelines defined the petroleum geopolitics, the electric highways can become the invisible arteries of the coming world.

Grok has become the last madness of Elon Musk, we create music with electricity and more in 1×20 crossover

by

Have New Crossover episodeand also with a very round number: it is the twentieth of this program in which we mix technology, opinion and entertainment and that as always present Jaume Lahoz and Carlos Santa Engracia. The beginning of the episode is already to grab males, because in crossover we have invited Álex, an electrical engineer and disseminator, to show us a brutal experiment: music made with lightning and electricity in the style Nikola Tesla. The section of a Popular Opinions premieres new questions that raise interesting debates. For example, do Chinese cars offer more than Europeans? Then we establish an interesting debate about that model of AI that is not spoken as much as it may be: Grok, from Xai, is Elon Musk’s attempt to win the AI ​​careerbut its approach is radically different from that of its competitors. In fact, it’s an approach A little crazy in which censorship shines for his absence. We certainly have much of what to talk about in this episode, so we invite you to enjoy it and, if you want, to share your comments and suggestions for this and future episodes. A for 1×20 crossover!
