What are lightning bolts and how are they formed, the impressive electrical discharges that scare and fascinate in equal measure?

by

The good news is that the chance of being struck by lightning this year is less than one in a million. Even better news is that 90% of people struck by lightning survive. Even so, it is always advisable to avoid risks when we are talking about atmospheric phenomena as violent as these. Lightning strikes cause both fear and fascination, a fascination that sometimes leads us to ask questions about the nature of these immense electrical columns. What is lightning Lightning is an electrical discharge (each lightning can generate several discharges), generally of very high power, that occur in clouds. These are meteorological phenomena that, although they have its origin in the atmospheresometimes they reach the surface of the Earth. We usually associate lightning with storms and cyclones, but these discharges can occur in other contexts, for example during volcanic eruptions, during fires of a certain intensity or when nuclear weapons are detonated. How lightning is formed Lightning usually occurs in stormy conditions and, the truth is that we do not fully know how. We know that under certain conditions, clouds can go accumulating electrical charges both positive and negative. In these cases, the air acts as an insulator between areas of positive or negative accumulation, as well as between these areas and the Earth. At a certain point, the accumulation of these charges exceeds a threshold that causes this insulating capacity of the air to give way. So all that accumulation of charges generates an electric current capable of traveling long distances (even several hundred kilometers). The discharge allows the electrical charge to balance, but the charges can accumulate again until the next lightning strike. What remains a mystery to us is the beginning of this process, how positive or negative charges accumulate in certain regions. The main hypothesis suggests that the origin of this accumulation is in tiny hail particles (also called graupel) that grow as they encounter supercold water droplets (in a liquid state but with temperatures below freezing). In thunderstorms, these icy particles would frequently collide, colliding with other icy particles. These collisions would cause the charges of the different particles to gain charge of one sign or another. Difference between lightning, thunder and lightning Electrical shocks are usually invisible to the human eye and they also do not generate noise, but this is not the case with lightning. Lightning generates not only a flash of intense light, but also a significant roar. We call the zigzag luminous path of lightning lightning. As it passes through the atmosphere, the electrical discharge causes the air to heat up to exceed temperatures of 27,000º Ceslius, a temperature higher than that observed on the surface of the Sun. This causes the air to become incandescent, generating lightning. Such rapid and intense heating of the air has another effect, making it “explode” outwards. This rapid movement of air is responsible for the second element that makes up lightning, sound or, in other words, the thunder. Light and sound move through the atmosphere at very different speeds. This is what makes us see lightning even seconds before its sound reaches our eardrums. This gap gives rise to an old trick to measure the distance at which the storm is from us. If we count the seconds of lag between light and sound and divide the result by three, we can estimate the distance in kilometers at which the lightning occurred. Types of lightning Cloud flashes and cloud-to-cloud Among conventional rays we can distinguish various types depending on the location of the points they join. The first of the groups that we can distinguish is that of the cloudy flashes. Most lightning strikes never reach the ground, in fact it is common for them not to even escape the cloud in which they occur. These rays are also often called intra-cloud rays. Within the category of lightning that never reaches the ground, there are some whose path partially escapes the cloud and even some that start in one cloud and reach another different cloud. Cloud-to-surface We distinguish these cloudy flashes and rays from those that do manage to reach the Earth’s surface. These types of discharges occur from the top down, at least when they happen naturally. The rays that join cloud and surface can be both negative and positive depending on where the respective negative and positive charges are located. Negative rays are the most common rays (they represent around 95% of impacts). In these rays, the clouds accumulate a negative charge and the Earth has a positive charge. When lightning opens the channel, the negative charge moves from the cloud to the ground, hence the name. The positive rays They are less frequent but at the same time more powerful. The reason is that these originate in higher areas of the cloud, so they must travel further. This in turn means that they accumulate more energy before discharging. Other unique events However, there is a different category that we call transient light events, or TLE (transient luminous events). These phenomena are much less frequent, more difficult to observe and, as a consequence, much more mysterious. How powerful is lightning? The strength of lightning can vary considerably depending on atmospheric conditions and the Earth’s surface. As explained According to the United States National Weather Service, a “typical” lightning strike can discharge about 30,000 amperes with 300 million volts. However, we pointed out before that a positive ray can transport much more energy. According to NOAA (National Oceanic and Atmospheric Administration), the organization on which the American meteorological service depends, these types of discharges can be an order of magnitude higher, discharging 300,000 amperes with 1,000 million volts. Many will wonder Why don’t we take advantage of this energy? and the answer is that, today, there are too many difficulties to make this technology a reality. First, we must keep in mind that lightning is a transitory phenomenon that can occur in different places: to obtain its energy we would have … Read more

Aerothermal energy is the heating of the future, but the electrical installation is stuck in the past

by

“Winter is coming”, read the iconic phrase of the Stark family in Game of Thrones. There are less than two months until the official arrival of winter and, with it, the time to see how our energy bill trembles as much as we do. Search formulas to heat the house becomes prevalent in this final stretch of the year, especially when heating continues to be one of the main reasons why electricity consumption skyrockets. Every season new technological promises appear to maintain comfort without emptying your pocket, and aerothermal energy has become one of the most popular.But the key question arises: can all homes really benefit from it? The rise of aerothermal energy. This technology It works in a very simple way: Harnesses the energy already in the outside air to heat or cool the house and produce hot water. Instead of generating heat by burning gas or consuming large amounts of electricity, this system “extracts” it from the environment and multiplies it. In practice, this means that for every kilowatt of electricity it needs to operate, aerothermal energy can produce up to five of useful heat or cold. While a radiator or boiler converts energy into heat directly, aerothermal energy does something more intelligent: it extracts heat from the air and multiplies it. According to the architects consulted by Arquitectura y Diseño They calculate that, in a medium-sized home, this difference can translate into savings of up to 35% annually, as long as the house is well insulated and the climate is favorable. For the pocket, it translates into about 100 to 130 euros less on the annual bill. So aren’t all houses ready? Although it sounds like a perfect technology, architects warn that not all homes can take advantage of aerothermal energy on equal terms. In fact, there are multiple factors that reduce its effectiveness: the type of home, its insulation, the location and the specific energy needs. In Mediterranean climates, for example, where passive design allows thermal comfort to be achieved without active systems, “it does not make sense to use aerothermal energy as the main heating or cooling system.” In other words, installing aerothermal heating without previously evaluating the home can be like buying an electric car without having a plug at home. Experts in sustainable architecture insist that energy demand must first be reduced and housing optimized before betting on advanced technologies. The state of the electrical installations is another of the great brakes on the electrification of the residential park. The Observatory of Electrical Rehabilitation of Housing warns that 80% of the houses have technical deficiencies, and that only 22.4% were built after the 2002 Technical Regulation. This makes it clear that the majority of homes continue to depend on old networks, poorly prepared to assume new energy demands such as those required by aerothermal energy or solar self-consumption. The signs to know if your home is suitable. Before considering installing aerothermal, technicians recommend doing a prior evaluation. OK with the expertsthese are the main technical requirements: Have a ventilated outdoor space, free of obstacles, to place the outdoor unit. Have a modern electrical installation and sufficient contracted power. Check the thermal insulation and carpentry: without a good envelope, the efficiency of the system drops. Adapt the existing heating system (for example, replacing conventional radiators with underfloor heating). Carry out a climate feasibility study: in very cold or hot areas, you may need support from another system. In short, aerothermal energy is not installed, it is prepared. A well-insulated house with modern electrical installation can convert air into free energy; An old home, on the other hand, can make it an expense that is difficult to amortize. Furthermore, if it is found that the initial investment It can exceed 8,000 euros for an 80 m² apartment. What if it is combined with solar energy? Where aerothermal energy deploys its full potential it is when combined with photovoltaic solar energy. This synergy multiplies performance and reduces dependence on the electrical grid. The energy generated by the plates can power the heat pump, achieving an almost self-sufficient system with an emissions balance close to zero. Furthermore, it has already been applied in real projects such as Casa Gualba, designed by Slow Studiothis formula allows the production of up to 17 MWh per year thanks to the integration of tiles and photovoltaic panels on the roof. In short, aerothermal energy and solar energy form an efficient tandem, as long as the home is prepared for it. Efficiency, yes, but with preparation. Aerothermal energy is here to stay. It is a key piece on the path to decarbonized homes, especially now that the European Union banned at the beginning of the year subsidize gas boilers. But, like all technology, it only works well when the environment supports it. Investing in aerothermal energy without first checking the electrical installation, insulation or orientation of the home can translate into frustration rather than savings. For this reason, it is advisable to do a good check and thus the air can become our best ally against the cold.

Data centers do not want to depend on the conventional electrical grid. Solution: build your own plants

by

AI data centers have sparked a new fever: the so-called “bring your own power.” The demand and consumption The pressure these plants impose is so enormous that they do not want to depend on external sources. The solution is theoretically simple, and we are already seeing how when a new data center is built, it is normal for some type of power plant to be built next to it. We are seeing it now. The data centers that OpenAI and Oracle are building in West Texas are accompanied by the creation of a natural gas-based power plant. Both xAI’s Colossus 1 and Colossus 2 in Memphis take advantage of gas turbines. And as they also indicate in The Wall Street Journalmore than a dozen Equinix data centers across the US are powered by stand-alone fuel cells. If the conventional electrical grid cannot be used, nothing happens: you create a power plant and that’s it. The US has an electrical problem. The technology giants would prefer to connect to the conventional grid, but bottlenecks in the supply chain, bureaucracy – permits, licenses – and the slowness in building the necessary transmission infrastructure prevent this. According to the ICV firmThe United States would need to add about 80 GW of new generation capacity per year to keep pace with AI, but right now less than 65 GW per year are being built. There is another direct consequence of this problem: the rise in the electricity bill. Data centers that look like cities. The needs and ambition of AI companies has made data centers become calculation and resource consumption monsters. One can only consume as much electricity as 10,000 stores in the Walmart electronics chain, WSJ estimates. Before 2020, data centers represented less than 2% of US energy consumption. By 2028 they are expected to represent up to 12%. A 1.5 GW data center, for example, would have consumption similar to that of the city of San Francisco, with about 800,000 inhabitants. China has a lot of advantage over the US in this. While the US deal with that lack of powerChina does not stop investing in new energy generation. According to data According to the National Energy Administration, the Asian country added 429 GW of new energy generation in 2024, while the US only added 50 GW. It is true that China has four times the population, but its centralized planning is helping to avoid problems that affect the US electrical grid. The white knight to the rescue. Faced with this shortage, natural gas has become the preferred resource for on-site energy generation. Although large turbines have long delivery times, smaller turbines or fuel cells that use natural gas are being used because of their rapid availability and installation. Renewables lose steam. Meanwhile, things are not promising for renewable energies (solar and wind, especially). There are about 214 GW of new generation theoretically in projectbut spending on such technologies could decline due to the potential loss of tax credits: the Trump administration criticizes that those clean energies do not provide a constant flow necessary for AI. The nuclear alternative. Faced with this apparent decline of nuclear energy, there is a growing interest in compact nuclear reactors (SMR), which allow us to provide the advantages of this type of center and a flexibility that can be very interesting for AI data centers. amazon, Google, Goal either Microsoft They are betting part of their future on nuclear powerbut that It doesn’t mean there aren’t challenges to overcome..

Europe needs tungsten for its electrical future. A Swedish mining company knows where to find it: Ourense

by

In the parish of Pentes, in the Ourense municipality of A Gudiña, the excavators have already begun to remove earth. There, on a slope where until recently only the mountain wind could be heard, the Swedish mining company Eurobattery Minerals AB has launched the work to extract tungsten – also known as tungsten –, a strategic metal for the European energy and technological transition. Galicia thus joins the small group of regions on the continent with active exploitation of this critical mineral. A strategic mine for Europe. The company, through its Galician subsidiary Tungsten San Juan, has launched its San Juan project while preparing its application for the second call for Strategic Projects under the European Regulation of Critical Raw Materials (CRMA), to open in January 2026. The first earthworks and the construction of a service warehouse are already visible in the area, as confirmed by the Vigo Lighthouse. When it is at full capacity, this will be the second active exploitation of tungsten in Spain, along with that of Barruecopardoin Salamanca. More in depth. The San Juan project will be an open pit mine with a goal that goes beyond local production: to provide European tungsten to the continent’s new industrial ecosystem. The company has begun improving infrastructure and constructing a pilot plant with gravimetric technology, while estimating reserves of 60,000 tons of ore with a grade of 1.3% WO₃. These are modest figures on a global scale, but significant for a Europe that seeks to reduce its dependence on Chinese imports of this critical metal. It has not been a short road. The procedures began in 2016 with geological studies, surveys and the construction of accesses, all under the supervision of the Xunta de Galicia. “Our goal is to produce tungsten responsibly and efficiently within Europe,” explains Agne Ahleniusgeneral director of Tungsten San Juan and former head of the Barruecopardo mine. “With this project, Galicia and Spain reinforce their role in the European supply chain of critical raw materials.” The metal that supports the energy transition. Few materials concentrate as much strategic value as tungsten. Its density, its resistance and its very high melting point make it a key resource for modern industry: from wind turbines to defense, including semiconductors and electric cars. But behind its technical brilliance there is a global conflict. China controls more than 80% of production and, in recent months, it has further limited its exports. The result: skyrocketing prices, uncertainty in the markets and a new reminder of how dependent Europe continues to be. To break this cycle, Brussels has launched the Critical Raw Materials Act (CRMA), a plan to guarantee access to critical minerals within European territory. According to the European Commissionthese initiatives not only seek economic stability: they also aim to reinforce the industrial autonomy of the continent and reduce its vulnerability to geopolitical tensions. Spain, a mining window. The start of the San Juan project is not an isolated event. It is part of a larger movement: the rediscovery of Spain’s mining potential. The country has projects of copper, tungsten, vanadium, graphite and cobalt, in addition to new deposits of rare earths in Estremadura and Gran Canaria. The European Union has set clear goals. It wants to stop depending on third countries for its supply of raw materials, and the new Critical Raw Materials Regulation (CRMA) mark the way: By 2030, at least 10% of critical minerals must be extracted within Europe, 40% processed on EU soil and 15% from recycling. Furthermore, no external country may concentrate more than 65% of the supply. On this map, Spain appears as a key piece: with Galicia, Castilla y León, Andalusia and Extremadura at the forefront, the country could become one of the gateways to the new European green reindustrialization. European autonomy is in Galicia. The roar of the excavators in A Gudiña not only marks the beginning of a new mine, but also the symbol of a change of era. Europe wants to leave decades of dependence behind and build a more sovereign and sustainable industry. From a Galician hillside, a small tungsten mine has become part of that strategy. What begins in Pentes may be, deep down, one more piece of the new energy and technological map of Europe. Image | Unsplash Xataka | The price of silver is exploding to levels not seen since 1980.

Voltage problems have returned to the Spanish electrical system and the big question is what have we been doing these last six months

by

The ghost of big blackout has returned to the fray: the Spanish electrical system has voltage problems. Serious problems, indeed. So serious that Red Eléctrica has had to ask for permission to take action on the matter. It goes without saying, but uncertainty spread like wildfire. Six months after the great blackout, Spain is living a little déjà vu. Are there reasons to be alert? What has happened? Electrical Network just notified to the CNMC which, for a couple of weeks, has observed sudden variations in voltage in the peninsular system. As he explained, this could compromise the security of supply and urgent measures would need to be taken to solve it. That includes temporarily modifying various operating procedures to stabilize the system while underlying problems are found. What do these modifications consist of? The proposals go from allowing technical adjustments to be applied directly during daily programming to giving the operator more room to act quickly if it detects a risk of instability, even before the operating day begins. In addition, it adopts stricter control of the automatic instantaneous balance mechanism and tightens the reactive voltage control. In summary, what has been notified is an express adjustment of the country’s electrical operations to contain the ups and downs in voltage that have been recorded. And all of this, to be implemented in five days. The big question is “now?” Because as Javier Blas pointed out“for months, the Spanish electricity grid operator (and the government) have been putting off the country’s electrical problems” and now, suddenly, a whole series of urgent measures are required. Red Eléctrica’s response. Given the concern generated by the request, the operator had to leave in passing, clarifying that there has been “no talk of a risk of imminent or widespread blackout”, that the voltage variations “have not posed a supply risk because they have been within the admissible limits”. However, the truth is that no one is too calm. As Blas said“The urgent request adds up to an additional $1 billion cost for Spanish customers as the grid operator is operating the system in what it calls a “boosted mode” since April 29 (in effect, operating gas-fired power plants more intensely and reducing solar and wind power).” If under these conditions the entire series of measures that have been requested are needed, there is some underlying problem. Or, at least, that’s what it seems: that the symptoms of stress in the system are clear and it is not at all clear that a handful of temporary measures are the solution we need.

Madrid plays 23.4 billion with data centers. The risk of losing them is in the electrical infrastructure

by

Madrid has managed to position itself as The great HUB Digital of Southern Europe For the data centers industry, but the electrical infrastructure of the twentieth century cannot support the growth of the 21st century. Why is it important. The Community of Madrid leads Spain in data centers with 23.4 billion euros in investments planned until 2028. But 82% saturation This leadership puts this leadership against other European regions. In figures: Madrid concentrates 54.8% of the national capacity of data centers with 216 MW in operation. The forecasts point to 522 MW when the works under construction and up to 1.7 GW in 2030. The sector has grown 33% last year and will generate 35,000 jobs in six years. The threat. Ayuso is preparing allegations against what he considers A “over -regulation” of the Ministry of Ecological Transition, but the real problem is on the network. Electric distributors denied six out of ten access requests last year. Without immediate improvements, Spain would have already lost 60,000 million in investments, according to the employer’s calculations, Spain DC, collected by Digital economy. Between the lines. The Madrid paradox is evident: The region produces just 1,334 GWh … … but consume 27,487 GWh per year. It is an energy black hole that works because Spain exports electricity and technological ones sign long -term contracts. But that does not solve the saturation of the distribution network. What is happening. The Government He has put a Royal Decree until September 15 which will force data centers to report their environmental footprint, energy consumption and water use. Madrid considers that it can subtract competitiveness, but it is a minor problem compared to the lack of electrical capacity. Deepen. Spain DC claims an urgent modernization plan, and The electric ones ask the CNMC to raise the remuneration rate of 6.46% to 7.5% To invest in a network. The cost will be paid by consumers at the light bill, but without that investment Madrid will lose the train centers train against Frankfurt, Amsterdam or Paris.

When the heat arrives, the boys fall in love, the solar panels have a fatal and Spain has a new electrical problem

by

Summer has arrived with excessive force To Spain. June has closed as the hottest month of which you have a record, and there is no indications that temperatures are going to give truce. The streets are emptied, public parks are deserted, and fans snort day and night as if trying to mark the rhythm of these unbearable days. But while life adapts as it can to this new heat, under the surface – where the invisible network that sustains modern life – heat has also tested the limits of the electrical system. High demand. While millions of people seek refuge under air conditioning, the Spanish electrical system begins to show saturation signals. Extreme heat triggers demand, reduces the efficiency of some sources of renewable generation and generates imbalances in the electricity grid. As collect the Iberian energy market operator (OMIE)on July 1, the price of the megavatio hour reached a peak of 167 euros at 9:00 p.m., an unusual figure for a night strip. The increase coincides with a high demand and a reduced renewable production at the end of the day, which forces the system to rely on more expensive technologies such as natural gas, According to Red Eléctrica España (REE). More heat, more network pressure. To all this is added an urban phenomenon that aggravates the pressure on the network: The island of heat. In cities, asphalt, concrete and lack of vegetation make the heat accumulated during the day stay overnight, raising the temperature several degrees with respect to rural areas. As a result, energy consumption does not descend after sunset, but is kept high for more hours. The households continue to light fans and air conditioning apparatus until well into the morning, which stress the system when the renewables have already fallen from the mix. But with more sun … The logical thing would be to think that with more sunny hours, Solar energy would suffice to meet the growing demand. And in part, it does: According to REE dataon July 1, renewables contributed 50.6 % of the electricity generated in Spain, compared to 49.4 % of non -renewable sources. But that daily average hides what happens in critical hours. From eight or nine in the afternoon, the photovoltaic disappears from the energy mix, just when the demand remains high and the temperature barely yields. At that time, they are the combined cycles – central that burn natural gas – that support the system, with more than 14,000 megawatts generated in some moments of that same night, According to REE data. There is an added problem. Solar does not always yield as expected: As we have already explainedpanels can have efficiency losses between 10 and 25% because of high temperatures. For each additional degree, they can lose up to 0.5 % yield. Nor does wind help too much: heat waves usually come accompanied by atmospheric stability situations that reduce the wind, which also lasts production. Will there be any blackout? Talking about generalized blackouts may seem exaggerated, but comparison with other countries, like the United Statesforces to take the threat seriously. However, the Spanish system has proven to have a certain margin of maneuver. After the blackout of April 28, they were activated Adjustment services to balance the network in case of collapse of the system at critical times. Although it avoids collapse, these mechanisms have a cost: they have more thanked the invoice part, especially for those in the PVPC rate. From that moment on, Ree has maintained an additional safety margin, operating with active backup power plants even when they are not in use, which structurally increases the operation of the system. Beyond the specific episode, that blackout exposed the deficiencies of a system that needs More storage, MicroRedes and greater local response capacity to disturbances. A system under stress. This summer is not only breaking temperature records: the margins of the electrical system is also testing. The combination of prolonged heat, night demand peaks and a more vulnerable renewable generation than expected is stressing the network at critical moments. The renewables are the present and the future, but they are not infallible. Its behavior also depends on the weather. And when the heat waves become the norm and not the exception, the resilience of the system depends on other factors: on the reinforcement of the networks, the storage, the demand management and, above all, to prepare the cities to resist without the most vulnerable paying the price.

In the twentieth century the pipelines were the key to the world. In the 21st century are the electrical networks and a country is winning them: China

While a nation installs almost one hundred solar panels per second, another revitalizes factories to produce gasoline engines. While A build the largest solar plant in the worldthe other promises “Dominant Energy” Based on oil and gas. At first glance, two different strategies seem. Actually, it’s a career. And the prize is not just energy: it is the geopolitical power of the 21st century. Two opposing models. An Ember graph published by Our World in Data He has illustrated The point with amazing clarity. At the beginning of the 2000s you can see China’s gradual rebound. However, the crossing occurs in 2010 where the Asian giant exceeds the 4,000 Teravatios-Hora barrier (TWH), to a vertiginous ascent exceeding 10,000 SWH in 2024. In simple terms, China produces more than double electricity than the United States, which remained in the same line. But the most relevant is not how much it produces, but how it does. Data Source: Ember (2025); Energy Institute – Statistical Review of World Energy (2024) The silent revolution. In just one month, China installed 93 gigawatts of solar capacity, which is equivalent – more or less – one hundred panels every second. To that are added another 26 GW in wind, some 5,300 new turbines underway. According to Lauri Myllyvirta, principal researcher at the Institute of Policy of Asian Society, cited by The Guardian: “Only the facilities of that month would generate as much electricity as whole countries such as Poland, Sweden or the United Arab Emirates.” In total, between January and May 2025, China has added 198 GW of solar capacity and 46 GW of wind, sufficient to match the electricity production of Türkiye or Indonesia. This way, Keep overcoming The more than 1,000 GW, which represents half of the world total. They have known how to get ahead. More and more linked climatic ambitions with the growth of renewable technologies. In a recent speech, cited by The GuardianXi Jinping linked the development of the clean energy sector with China’s economic revitalization: “We have built the world’s largest and most complete energy chain in the world.” The term “new energies” includes renewables, batteries and storage technologies. The Asian giant is currently the largest global supplier of clean technologies: the market of solar panels, wind turbines, batteries, electric vehicles and nuclear reactors under construction dominates. In addition, it has almost 700,000 patents in clean energy, more than half of the world total, According to The New York Times. The other face. For a good part of the twentieth century, the United States was the reference in energy innovation: from the first commercial solar cells until The first wind farms. However, since Trump’s arrival, the focus It has been placed again strongly towards fossil fuels. According to The New York TimesWashington has pressed allies such as Japan and South Korea to invest billion dollars in American natural gas infrastructure. At the same time, companies such as General Motors have given clear signs of where the wind blows: the company canceled an electric motion plant near Buffalo (New York) to allocate 888 million dollars To manufacture gasoline V-8 engines. Where asymmetry resides. It is not just two different paths, but in world influence. According to Climate Energy Finance datathe companies of the Asian giant have announced more than 168 billion dollars in foreign investments in clean energy projects: from turbines in Brazil to electric cars in Indonesia, through gigantic solar plants in Saudi Arabia and hydroelectric projects in the Congo. Green energy, for Beijing, is not just a business. It is a soft power tool. A way to gain global land through infrastructure, long -term contracts and own financing. An influence that does not need military bases, but solar panels. In contrast, the United States has cut many of its international energy cooperation programs. Its foreign strategy is more transactional: specific gas, oil or even weapons agreements. But without a structural project that allows you to compete on this new energy board. And this change of roles? Half a century ago, the United States led energy innovation. In 1979, Jimmy Carter He installed solar panels In the White House. Decades later, Barack Obama financed projects like Tesla. But cases Like Solyndra’s failurea solar company that broke after receiving a federal loan, unleashed a conservative narrative against public investment in renewables. China, on the other hand, assumed risks. In the early 2000s, then Prime Minister Wen Jiabao – rare earth geneologist – understood that the country’s economic and geopolitical future went through controlling energy production. Your government invested hundreds of billions of dollars in subsidies, factories, technical training and innovation. Protected his market, automated manufacturing and dominated access to essential raw materials such as lithium, cobalt and silicon as has developed New York Times. The forecasts. The world is moving towards solar and wind energies, so confirms it The International Energy Agency. The energy demand will continue to grow, but its origin will be different. And that will change the global balance, because whoever leads this new energy matrix will also have a geopolitical, commercial and diplomatic advantage. China is prepared to lead that world. The big question is whether the United States – or any other global actor – is willing to compete with the same strategic vision, patience and scale. Because energy not only moves factories or illuminates cities. Today the global board moves.

A country has literally found the bomb -proof solution to the large electrical blackouts: Ukraine

by

It happened a few hours ago. Among the multiple calls that the Spanish Government has received from countries, worrying about the emergency situation after The national blackoutone did not go unnoticed. Zelensky, president of Ukraine, called Pedro Sánchezand not only to show your support, but to provide all the necessary help. After all, if anyone knows about blackouts, that is the nation of the East. They have learned to survive in the dark and Russian bomb proof. The devastation of the electrical system. From the beginning of the large -scale invasion in February 2022, Russia has directed a good part of its attacks against infrastructure Ukrainian energy. Last summer, Ukraine had lost and in just three months More than nine gigawatts of generation capacity, more than a third of the one it owned before the war. According to Ukrenergo dataThis would be equivalent to the total demand of countries such as the Netherlands at peak hours, or even the sum of Slovakia, Latvia, Lithuania and Estonia. Winter. All state thermal plants were destroyed and all hydroelectric plants had suffered damage to missiles or drones. The strategy of Russian attacks was clear: it was not only sought to destroy military capacity, but to break the soul of a society through forced darkness, interrupting the most essential: Heating, running water, elevators, communications, operating rooms or the simple possibility of maintaining an organized civil life. Today, and according to the UN agency for refugees, More than 60% From the country’s electricity generation capacity it has been destroyed or useless. In a country where winter is not only a station but an existential threat, running without energy is running out of heating, without water, without communications. For millions, electricity represents the last bastion between dignity and precarious survival. Survive blackouts. He told the last July the BBC that the blackouts in Ukraine had become a presence as constant as the war itself. In cities such as Odessa, Kyiv or Zaporizhzhia, electricity was an intermittent luxury, a resource that appears and disappears under the buzzing of the generators or the sepulchral silence of the fallen network. In that context, electricity ceased to be just a comfort to become the threshold between life and death. Cases like Tetiana’smother of a child with serious disabilities, who lives that truth every day: her son depends on breathing machines, feeding and receiving medication. Without stable supply, his life hangs from a thread. In your home, prolonged blackouts (sometimes twelve hours a day) force to constantly feed a gasoline generator that, in addition, must stop every six hours so as not to overheat. When your child convulses, the minutes without mobile or ambulance coverage are transformed into torture. In words to the British environment“You can die if you don’t receive oxygen. I am missing words.” Thus thin is the line between chaos and survival. Scheduled cuts. In August of last year there was a substantial change in the struggle of Ukraine to the blackouts. A Mondayhundreds of missiles and Russian drones fell on the nation. First the electricity was cut, then the water. That day marked the Greater Russian air attack against Ukrainian energy infrastructure since the beginning of large -scale invasion. The bombing continued the next day, raising the number of deaths to twelve and leaving millions of people throughout the country. The largest private energy company in Ukraine, DTEKmade a decision: Apply scheduled cuts In multiple regions: Kyiv, Odesa, Dnipropetrovsk, Donetsk. On the periphery of the capital, the neighbors began to live with six hours of blackout followed by two hours with electricity, in the early morning. A rhythm that allowed planning (even if not resting). Loading with energy. The result of the situation is that Ukraine has learned to live with the blackouts. What would have paralyzed the country before, today faced with Decentralized solutions. In Kyiv, the so -called “invincibility points” offer citizens electrical charge and the Internet during the cuts. But many do not even go to them: they have made portable batteries an object as essential as mobile phone or keys. Most shops, from street stalls to shopping centers, already have their own generators. In fact and as we said, that buzz of its engines has become the usual soundtrack of the blackouts. Examples Told the CNN Maksym Holubchenko, a 25 -year -old barista in the capital, that his cafeteria remains open thanks to one of those generators. However, it does not supply to cover all the demand: in winter you can maintain the operation, but in summer they must turn off the air conditioning and parts of the coffee maker so as not to overload the system. Adaptation is not comfortable, it is simply the result of an urgent need, and a resistance without alternatives. For Inna, an 87 -year -old woman from Odessa, the current situation arouses ancient echoes. “I already survived World War, so I have some experience … I bought candles,” He reported. His story underlines a painful paradox: a modern, European country, with full integration ambitions in the West, forced to technologically retreat, to depend on the rudimentary to face the essential. The candles, thermos, the portable loaders, the calendars marked by electric cuts … make up a new normality born of the energy siege. Go to the bank without light. Before prolonged blackouts caused by Russian attacks on energy infrastructure, the National Bank of Ukraine has also launched the Power Banking Projecta network of autonomous bank branches designed to operate without depending on the electricity supply. These “unwavering” offices will be equipped with generators, special communication channels, ATMs, additional and effective personnel available, allowing citizens to access essential services such as money withdrawals, payments, transfers, currency change and financial advice even during prolonged cuts. In addition, a “National Roaming System” Between ATMs, with unified limits and without commissions between banks, initiative already adopted by entities Like Oschadbankto guarantee equitable cash access throughout the country. Broken as a resistance symbol. In short, Ukraine applies preventive cuts Not only … Read more
