The most drunk beer brands in each autonomous community of Spain, gathered on this map

by

Beer does not pass through his best moment in Spain, but that does not mean that ours continues to be a country of reeds in which per capita consumption exceeds on average 50 liters. Yeah we go down to detail and we analyze what brand those rods or bottles are, however, things change from one community to another. In Galicia and the Balearic Islands Estrella Galicia reigns, in Andalusia Cruz Campo does it, in Catalonia Estrella Damm and in the Valencian Community and Cantabria Amstel. There is, however, one logo that dominates a good part of the map: Mahou. What has happened? That we have a new ‘photo’ of the beer sector in Spain. It does not show us data per capita consumptionevolution of demand or billing of the sector, but it does give us a clue about another equally interesting topic: the struggle between brands at a territorial level. He latest report ‘Brand Footprint’, prepared by Worldpanel by Numerator and published by Mahou San Miguel itself, reveals two interesting facts about the Spanish map. The first is that it remains highly segmented at a territorial level, with brands consolidated by region. The second is that, despite this diverse scenario, there is one brand that clearly leads: Mahou. Worldpanel by Numerator report. What exactly does it show? The Worldpanel by Numerator (formerly Kantar) report basically shows which brand is “the most chosen” in each autonomous community. To find out, the technicians carried out a survey with a “representative” sample of 12,500 homes spread throughout Spain, including the Balearic Islands and the Canary Islands. The result, which you can see in the map that heads this post, is that Mahou leads in Asturias, Navarra, Castilla y León, Castilla-La Mancha, Community of Madrid and Extremadura. And the rest of the country? It is dominated by brands that have become strong at a territorial level. Estrella Galicia stands out, for example, in Galicia and the Balearic Islands, Amstel in Cantabria and the Valencian Community, San Miguel in the Basque Country, Estrella de Levante in the Region of Murcia, Cruzcampo in Andalusia, Estrella Damm in Catalonia, Ambar in Aragon and Cerveza Tropical in the Canary Islands. The question remains as to what is happening in La Rioja. There the sample did not allow the authors of the report to reach a clear conclusion. It is not a bad balance for Mahou, who wanted to emphasize that the Worldpanel study proves that the brand has strengthened its presence “throughout the national territory” and maintains leadership in half a dozen regions. If compared with the 2025 study The firm loses the leadership of Cantabria in favor of Amstel and takes over Navarra, a territory that San Miguel controlled last year. The Madrid company also boasts of the weight of its brand in the shopping basket, establishing itself as one of the most popular in its branch. But… And Galicia star? The Worldpanel by Numerator map may catch your attention if you remember another on the same topic published in September and produced by Data Centric. It showed a ‘photograph’ quite differentwith Mahou based mainly in the Community of Madrid and Castilla-La Mancha and Estrella Galicia monopolizing Galicia, Asturias, Castilla y León, Extremadura, Cantabria, the Basque Country, Navarra, La Rioja, the Valencian Community, the Balearic Islands and Melilla. What is the reason for this difference? To focus. Because? Although both reports are based on a quantitatively similar sample (DataCentric conducts 14,053 digital surveys), they do not seek exactly the same thing. The Worldpanel study points to “the most chosen beer” by Spaniards. DataCentric “favorite brands”. In his report he states in fact that the Hijos de Rivera brand receives “42% of the votes” compared to 14% for Mahou and leaves behind a reflection: despite how well positioned both Estrella Galicia and Alhambra are in their ranking, this status of “favorite brands” does not then translate to sales. “Both have significantly lower positions.” If we look at billing, for example, the business ranking of theEconomist shows that Mahou is in the lead, followed by Damm, Heineken and in fourth position Hijos de Rivera, the parent company of Estrella Galicia or 1906. In general, both the DataCentric and Worldpanel reports should be taken for what they are: studies with their strengths and weaknesses that help to better understand a sector that faces a challenging landscape. Although Spain is one of the EU countries that consume more beerthe industry deals with a youth that is changing their consumption habits and approach to alcohol and a market in which they are gaining more and more strength ‘without’ drinks.

5.4 million earthquakes gathered in an interactive 3D map

by

Every day we detect 55 earthquakes on average, but one thing are earthquakes monitored and followed by the global network and another are microseisms: there the figure rises to 1,300 a day, according to data from the American National Earthquake Information Center (NEIC). It is totally and absolutely normal: the Earth is a dynamic system in constant reconfiguration where the movement of the tectonic plates releases large amounts of energy that seismography is responsible for recording. And thank goodness: beyond the impact and catastrophe of the largest earthquakes, these enormous databases are essential to predict them. But databases are unfriendly, so the EarthScope Consortium integrated into IRIS Data Services has developed the Interactive Earthquake Browsera seismic visualization tool that allows you to explore more than 5.4 million earthquakes on an interactive global map in Google Maps. The data comes precisely from the catalog of the USGS National Earthquake Information Center, the highest authority on the subject. The world map of earthquakes. The map shows complete global seismicity from 1970 to the present with dots. Each point represents an earthquake, and its position, size and color serve to qualitatively identify its geographical location, its magnitude and its depth of focus. The view can be overlaid with tectonic plate boundaries, making the map a direct tool for reading the internal structure of the Earth. This format allows you to identify at a glance the areas of greatest seismic activity and danger, such as the Pacific Ring of Fire or the oceanic ridges. The world map of earthquakes. SAGE How to use it. The points are just the beginning. In addition to being able to change the view from map to satellite format or zoom in on a specific area, it is possible to activate the 3D view, view animations or export the data directly to Excel or CSV to work with them. You can even change the data source to MIXED, which incorporates records from the International Seismological Center and expands coverage of small events outside of North America, although with less reliability in location. The most interesting thing is the filters that appear in the right column, which allows you to choose how many earthquakes to show in the window, select time intervals, magnitude and depth. The map of earthquakes in the Iberian Peninsula Some seismically hot areas. The Pacific Ring of Fire concentrates approximately 90% of all global seismicity and is the most visible region on the map: it includes the western coasts of America, the Aleutian arc, Japan, the Philippines, Indonesia and New Zealand and has earthquakes of all colors. The largest earthquake ever recorded, the Valdivia from 1960 with a 9.5, it occurred precisely there, in the subduction zone of the Nazca Plate under the South American Plate. It is followed by the Alpine-Himalayan arc, whose concentration of seismic activity on the planet is explained by the continental collision between the Eurasian, African and Indo-Australian plates. In this case, earthquakes rarely exceed 300 kilometers in depth, but they can be devastating due to their proximity to large population centers. The East African rift system is fascinating: it is an area where a continental plate is actively breaking up, with diffuse seismicity that marks the future boundary between two new plates. Why it is important. Visualizing global seismicity as a whole allows us to quickly recognize the boundaries between tectonic plates, the areas of greatest activity and the deep structures of the planet, something that normally escapes our eyes. This capability is essential for both research and seismic risk assessment in densely populated regions. For science, the option of filtering by depth is especially valuable as superficial, intermediate and deep earthquakes respond to different physical mechanisms and are located in very different geological contexts. Being able to separate and compare these groups facilitates the interpretation of data compared to a statistical analysis of the databases.

Someone has gathered more than 13 million public contracts and has set up the Google of public procurement in Spain

by

Every euro spent by a State Public Administration must be traceable by citizens. We don’t say it, the law says it. But theory is one thing and practice another: if you try, you will discover that sometimes it is a long, tedious and sometimes almost impossible mission. Let me explain: when someone wants to know which company a public hospital or city council has awarded contracts to, the official search path forces them to go through different platforms ranging from Public Sector Procurement Platform state to autonomous regions such as those of the Community of Madrid, the Basque Country or Galicia, because there are CCAA (quite a few) that have their own system and do not publish in PLACSP. This fragmentation makes the search difficult, as details the Public Procurement Observatory. So an engineer has set out to solve it by building a search engine for Spanish public contracts. The “Google” of public contracts in Spain. jobsearch.com solves this fragmentation problem with a single search engine. It is an independent project that aggregates, cross-references and allows you to consult in seconds the public procurement information that the State publishes dispersedly on a long list of different platforms. More specifically, it draws from 10 official sources, including the State Platform (PLACSP), the Official Journal of the EU (TED), and regional platforms of Madrid, Catalonia, Galicia, Andalusia, the Basque Country, Asturias and the Valencian Community, plus data from the Commercial Registry. The result is a search engine with around 13.4 million indexed contracts, without advertising, without tracking and with open source available on GitHub. Behind the project, Gerard Sanchezprogrammer and founder of BQuant and professor at the University of Navarra and the UPF Barcelona School of Management. Why is it important. Public procurement is not trivial: in Spain it moved more than 113 billion euros in 2024, the equivalent of 10.92% of GDP, according to the OIReScon Annual Surveillance Report 2025the official supervisory body of the Ministry of Finance. Each year a sum of money is allocated through procedures that must be public and auditable. The reality is that this audit is very difficult without tools. A CNMC report of 2019 highlights that public procurement represents between 10% and 20% of Spanish GDP and that Spain is one of the European countries with the lowest participation of companies in tenders: only one company participates in one in three state contracts. With data access tools that facilitate transparency, competition could be increased and the cost for public coffers reduced. Context. In Spain there are several laws that require public contracts to be published: there is the Law 19/2013 on transparency, access to public information and good governance with a triple objective of increasing transparency in public activity, guaranteeing access to information as a right and establishing good governance obligations for public officials, but also the Law 9/2017 on Public Sector Contractswhich is a transposition of European directives on public procurement. So the problem is not that there are no regulations, but rather their application and the dispersion of data. As explains the Public Procurement ObservatorySince March 2018, it has been mandatory for the entire public sector to publish the information on their contracts in the PLACSP, but the tool is also a headache as thousands of entities upload information manually and with free-writing text, which constitutes a continuous source of error. PreciselyBuscalicitaciones.com detects and documents these inconsistencies. How it works. Technically, the project downloads and normalizes the open data that each of those 10 official platforms publishes in structured formats such as XML, JSON, CSV. Each record is crossed with data from the Commercial Registry to enrich the information of the successful bidder. The search engine offers three main modes of use: search for contracts by winning company, contracting body, CPV sector or free text of the contract; see the complete history of awards of any company by its NIF and consult a public registry of contracts with anomalous amounts greater than 1,000 million euros. Yes, but. The first major limitation is structural: it depends on the quality of the data published by official sources and that quality can clearly be improved. If the source data is bad, the aggregator inherits that error. And we have already seen that sometimes it is and that it is certainly anything but homogeneous. On the other hand, this is the first version of the project and it shows: It has flaws and the coverage is not complete. Navarra does not appear on the list and sources such as the Valencian Community do not have an aggregate amount available, the Basque Country only has an amount in 106,000 of its 651,000 contracts and Catalonia has two separate entries with different coverage. On the other hand, the independent and altruistic nature of this public utility resource also has its B side: long-term sustainability, given its great magnitude.

All the lighthouses that illuminate the coasts of the North Atlantic, gathered in an impressive interactive map

by

The figure of the solitary lighthouse keeper in charge of the thankless task of keeping his tower operational and in good condition at the service of the boats has long been a rare sight: they are in danger of extinction in front of the automated towers, both in terms of lighting and other auxiliary tasks within of the DGPS differential system. There are (almost) no lighthouse keepers, but the lighthouses look like never before. Only Europe’s 90,000 kilometers of coastline They are a veritable garden of lighthousesbut one thing are lighthouses (that iconic tall tower with a light on top) and another is lights for maritime signaling, where large lights, small lights, beacons or buoys enter. The reference technical standard is IALA Recommendation E-110, as collects and translates into Spanish Puertos del Estado. If we talk about maritime signage, things change there and the figures increase: there are 23,217 lights in the northern seas alone, according to OpenStreetMaps. It must be considered that this is open data, provided by the community, with areas very well mapped and others not so well. The lighthouses of the North Seas, as we have never seen them If we stick to the northern seas, the lighthouses drop to around 2,500 units. Although his thing is teaching and business, Wharton University professor Ethan Mollick has condensed all this information into an interactive map using vibe coding: Lighthouse Atlas. Lighthouse Atlas This map of the northern seas is more than a mere cartography of that maritime signage: it is interactive, making it a tool as visual as it is impressive for the possibility of playing with zoom, filtering or the information it shows. If you also hover over the lights, you can see more data such as their name, color range or frequency. In addition to being able to filter to see only the headlights (‘Major lights only’), as Mollick explainseach light has the correct color, each flashes with the appropriate frequency, and its brightness has been scaled according to OSM data. You can also see how far away they are visible. How far are the light signals seen in the Atlantic, between the Spanish and French states Thus, the size of the points serves to get an idea of ​​how close or far the vessels can be to view the signals. For example, on these lines you can see how much the signals of the muga between the Spanish and French states illuminate. Especially striking because of how congested the Norwegian coast is, as can be seen numerically. in the database from Norsk Fyrhistorisk Forening, the company that compiles a detailed map of locations along the entire Scandinavian coast. However, of the historical 212, it has about 150 operational. It is not the only one: Scotland and the Isle of Man, the coasts of Denmark and the Adriatic Sea, on the coasts of Greece and Türkiye are also well nourished.

Satellite images have revealed that China has gathered its most important aircraft carriers. And that can only mean one thing

by

The simultaneous appearance of the two ends of the Chinese aircraft carrier fleet, the Liaoning veteran and the newly incorporated Fujiandocked at the same naval base does not seem to be a logistical coincidence, but rather a carefully eloquent image. One that can only mean one thing: it is training naval “one plus one.” Two aircraft carriers, one message. Satellite images show both ships moored in Qingdaoa port historically linked to the development of Chinese naval aviation and now expanding to accommodate a new phase of maritime ambition. Together, they represent the past learned and the future being rehearsed: the transition from a regional navy to a force of waters blues capable of operating in a sustained manner far from their shores. From symbol to real capacity. China already has the largest navy in the world by number of hulls, but the qualitative leap is marked by embarked aviation. Entry into service from Fujianthe first Chinese aircraft carrier designed from scratch with electromagnetic catapults introduces a capability that until now was only dominated by the United States. In front of him, Liaoning brings more than a decade of operational experience. The coexistence of both on the same dock points to something more than maintenance: it suggests doctrinal integrationknowledge transfer and the practical initiation of group operations with multiple aircraft carriers, a threshold that separates regional navies from truly global ones. Qingdao as a laboratory. Side by side mooring It’s unusual and deliberate.. It coincides with the declaration of restricted maritime zones in the Bohai Strait and the northern Yellow Sea, a classic indication of imminent exercises. Everything points to joint training in which aircraft departure rates, deck security, logistics, command and control, and coordination between air wings will be compared. The objective is not only for Fujian to learn from Liaoning, but to see how two platforms with different capabilities can operate. as a single systemmultiplying its effectiveness. In naval terms, it is not about adding ships, but about creating operational synergies. Beyond the Strait. The Fujian’s movement northward, crossing the Taiwan Strait without aircraft on deck, has been closely followed through Tokyo and Taipei. Precisely this detail reinforces the reading that it is not a combat mission, but rather a training one. The background, however, seems unequivocal: Beijing wants to break the logic of the First Island Chain (the arc that goes from Japan to the Philippines via Taiwan) and demonstrate that it can project power beyond it. Operating two aircraft carriers in a coordinated manner is key to sustain presenceprotect distant sea lines and provide credible deterrence against US aircraft carrier groups. Implicit response to Washington. The Pentagon assumes that the People’s Liberation Army Navy is in the early stages of operating a multinaval force with aircraft carrierprogressively expanding its radius of action. The continued presence of US aircraft carriers in the Indo-Pacific, under the logic of containment and defense of allies, acts as a catalyst for this process. If you will, China somehow seems to say that it does not need to announce a doctrine for the message to get through: the image of two aircraft carriers together in Qingdao communicates that accelerated learning has begun and that the operational gap is closing. The power of tomorrow. There is no doubt, the analysts match in that these movements do not indicate an imminent conflict. But they do reveal patient and methodical preparation. Crew integration, procedure comparison and dual command testing are essential steps for a navy that aspires to operate autonomously in the Western Pacific and beyond. Japan watches it with special attention because you have already seen Chinese aircraft carriers cross its defensive perimeter in recent exercises. Each deployment, each joint training, normalizes what a decade ago would have seemed exceptional. The threshold that China wants to cross. In short, the true meaning of Qingdao is not in the number of tons or the technological novelty of Fujian, but in the sign of maturity. Going from an experimental aircraft carrier to a couple training together is crossing a strategic threshold. It is not the prelude to war, but to status. China rehearses today the choreography that will need tomorrow to hold your global maritime ambition. And in that essay, the message to allies and rivals is clear: the era of the lone Chinese aircraft carrier is behind us, and that of the carrier group has just begun.

The countries with more nuclear bombs in 2025, gathered in this graph with two protagonists: China and India

by

In January 2007, the Watch of the Last Judgment remained at five minutes of the devastation. In January this year, I was barely 89 seconds of midnight. This clock represents, symbolically, if we are close to a nuclear devastation, and the data of 2025 was the most bleak in its 78 to those of history. Although the United States and Russia continue to dismantle nuclear arsenal, they are still the powers that more atomic bombs have. However, China is putting the batteries And another country wants to demonstrate that it has no qualms about arming: India. And this graph perfectly represents the situation of world nuclear arsenal in 2025. The photo in 2025. Prepared by Visual Capitalist From data from the Stockholm International Peace Research Institute, or Sipriin the graph we can eloquently see the state of the nuclear arsenal until January this year. The United States and Russia evidently dominated The world nuclear arsenal during the Cold War and, although they are still the two nations that have the most ojas in their possession, that arsenal has been diminishing. During the last months, it is estimated that the United States would have discharged eight eyes while Russia would have ‘retired’ another 71. France and the United Kingdom, which recently confirmed actions to combine their arsenalThey are maintained, like Pakistan, Israel and a North Korea that has a secret arsenal, but with an estimated 50 heads. As can be seen in the image, the US and Russia continue to dominate the segment incontestable, but there is a third country that, also evident, is taking leaps and accelerated to get a good arsenal. China. About a year ago, A SIPRI report He surprised everyone by showing that China was increasing its nuclear arsenal at a stupid speed. Now is in a position that allows Ask for both the US and its allies With nuclear arsenal and that Chinese expansion has been the perfect excuse for the “Rearme” that the Pentagon has asked for. Of the 500 estimated heads of China in 2024, we went to 600, which represents 20% more in a few months that allows to see in an evident way that the Asian giant has taken the renewal of its forces seriously. Nuclear weapons investment is not the only thing we have witnessed, since China boasts electromagnetic catapults of his new warships, of latest generationof New combat fighters and Even a huge poaching plane. India puts the batteries. Despite those 600 heads, it is estimated that they have less than 30 strategically deployed (those that are ready to launch). The United States and Russia have less than 2,000 deployed, France has almost all lists to launch and the United Kingdom half, more or less. The one estimated that it has zero deployed bombs is India, but the new SIPRI report shows that the country’s nuclear investment is paying off. In fact, and without knowing really how things are going in North Koreait would be the only country that has increased its arsenal, adding another eight heads in recent months. They have reached 180 and arrive just at a time of high voltage in the Indo-Pacific region, with continuous demonstrations of force As the other big in the contest does, China. New generation of bombs. The current situation is … complex. With the invasion of Russia to Ukraine the Fear of nuclear war. With the recent conflict between Israel and its neighbors, Those drums have sounded again And, meanwhile, China promotes pacts not to attack first with nuclear arsenal while the treaty expiration is approaching START III which limited the amount of strategic weapons deployed by nuclear powers. Russia se He disconnected of that treaty, directly, in 2022. We will see in a few years how graphics of this type evolve, since France confirmed In 2024 a program to produce Nuclear bombs New generation and more recently they bet on new Actions to consolidate your role as one of the pillars of nuclear deterrence in the West, something that blocks with the Objectives of Rearme launched by Europe.

The most self -sufficient countries on the planet at the food level, gathered in a surprising graphic

by

Humanity has eaten what it played For thousands of years. With globalizationhe has started eating what he wants and that, together with the population increase, It has consequences. Not being able to meet the demand of some foods, Import is a necessity. But it turns out that there is a unique country in the world, a completely self -sufficient one if we talk about food. Guyana The All-Star of Self-sufficiency. In the upper graph, prepared by Visual Capitalistwe can see the 50 most self -sufficient countries in the world at the food level. It reflects seven food groups: Fruit. Vegetables. Legumes. Starchy foods such as flours or rice. Meat. Fish. Dairy. And the only country that not only complies, but exceeds the production of what its population of each of these groups needs is Guyana. It is a small country of about 815,000 inhabitants located in northern South America that has shot your GDP These last years. Partly, thanks to discovery Of great oil reserves in 2015, but before that boom, their agricultural and mining industry were the ones that pulled the car. Closing the podium. So much that it is, as we say, the only one that produces its own food in all groups, highlighting in one that does not usually highlight: starchy foods. Closing the podium, we must look at Asia. Vietnam and China are two other countries that meet in six of the seven groups. The common strong point is the production of meat and fish (Meritory in the case of China, but At the expense of half -world folders). The weak is that of dairy products. It is common in Asia, with cases as dramatic as Indonesia, Thailand, Tonga, Laos or Philippines, which satisfy 0% of their dairy consumption with the national product. To the tail … On the other side of the balance we have Armenia, Thailand and Greece. The three countries are in the group of those that meet in the production of four categories (where the vast majority of countries are found), but with low percentages in general in almost all groups and a total dependence on dairy and vegetables in the case of Thailand, starchy and, curiously, fish in the case of Greece and legumes and fish in the case of Armenia. Europe and the fruits that come through those who come out. Taking an eye on the panorama of the member countries of the European Union (Greece is an example), we see that some falter, others stand out. And vice versa. The north, for example, does not get along with the Fruit culturesomething that does stand out in the countries of the South. The key in this case is the Single market Agricultural that allows food products to circulate freely between member countries, without regulatory tariffs or barriers. More than 70% of EU’s food products is carried out between member countries, being something that ensures balance and supply even in cases of local productive problems.

The countries with the greatest natural gas reserves, gathered in this graphic developer

by

Natural gas has become a bridge fuel on the road to decarbonization. Emits less dioxide that coal or oil when used to generate electricity, and in a world that is hitting the Volantazo to renewable energiesgas has established itself as a vital element. Reason? Is being used to feed the voracious data centers And, in addition, it is A geopolitical element. And there, countries with the largest natural gas reserves have a lot to say. And that mixture between natural and geopolitical resources can be seen perfectly in this graph elaborated by Visual Capitalist: The powers. Russia, Iran and Qatar are the indisputable powers when we talk about natural gas reserves. The United States stays close, but the first three, according to these data from the US Energy Information AdministrationThey represent 51% of those world reserves. And the first ten countries, which are represented in the graphic, accumulate 83% of the total natural gas. Russia is the clear clear, with twice more than Qatar and almost tripling the reserves of the United States. The closest is Iran, Another oil power. Protagonist role. And who controls gas, controls a large percentage of the world energy cake. It is estimated that, currently, natural gas represents 23% of the global energy mix. This depends on the country, of course, but one of the largest whales is the United States and there represents 40% of the electricity generation. The reasons are the amount of and efficiency, being your Great advantage which is the most ‘dispatchable’ energy source. It can be activated and deactivated easily and, in a matter of minutes, operates with a capacity greater than 80% to satisfy demand peaks. In addition, what we have already commented: its emissions Co₂ are approximately 50% lower than coal and 30% lower than oil. Trend. The graph represents the status of reservations in 2023, but with more recent data, we see that it is still an essential fuel: Natural gas meant 33% of the increase in world energy supply. The demand for natural gas in 2024 increased 2.5%. Electric generation from natural gas also grew by 2.5%. Natural gas production increased 1.2%. And world trade by gas pipeline and LNG increased by 3.3%, being the first time it grows from 2021. Geopolitics. And that only a few countries have such an essential fuel for the rest, it implies that it is a source of economic, diplomatic power and, in times of crisis, also a weapon. In Europe we have witnessed this from two different fronts. Before 2022, near the 40% of European natural gas was Russian. The invasion of Ukraine caused a series of cuts in the supply and Russia He used it as a weapon in the contest‘drying’ the countries of the European Union that supported Ukraine. This has led the EU to rethink your energy safetydiversifying energy sources and investing in infrastructure such as those of the Green Hydrogen Corridor. And, in this situation, the US has gained weight becoming the largest gas exporter to Europe, using this resource in the Tariff trade war. Artificial intelligence. Beyond politics, this ability to satisfy demand peaks is something that is erecting natural gas as the most important fuel today. Data centers require something called “operational reliability”, or what is the same: they cannot stop working and They cannot depend on renewable energieswhich may have intermittent periods of activity, be their only energy source. In addition, at certain times of computational demand peaks, They need a huge amount of immediate energyand that is where natural gas can meet that demand. The energy need for these is such Data macrocentros that there are companies that are choosing to take over nuclear energy plants to meet your needs. Gas for a while. The natural gas is a complex scenario because, although we want to get rid of it in favor of renewable energies, factors such as its energy advantage and strategic pacts favor that it is rope for a while. The projections indicate That the energy demand of data centers only in the United States will grow from 180-290 twh from 2024 to 515-720 TWH in 2030. In the rest of the world, It will pass of the 415 TWH to 945 TWH in 2030. Globally, other analysis They point to an increase in that 50% demand by 2027 and up to 165% by 2030. Beyond the needs of the data centers, it is wait An increase of 32% in the world demand for natural gas by 2050, being Africa and Asia the main driving regions of this growing demand due to electrification and industrialization needs. These estimates can go to the fret if a Unexpected increase in renewables Thanks to new technologies or more efficient solutionss, or if the panorama of the data centers changes, but what is evident is that the Camino to decarbonization You will have to live with natural gas.

The most bestial data centers on the planet, gathered in this graphic

by

The development of AI has promoted a New ‘Armamentistic’ career globally. It is not sought to dominate another territory, but to get the more computing power, the better. The main technology companies are deploying centers from Data around the world With a goal in mind: train the artificial intelligence. There are data centers that are authentic burged, and in this graph we can see the most powerful data clusters in the world with an outstanding protagonist: Elon Musk. Cluster. Before entering numbers, a nuance. When we talk about calculation power, we can talk about a computer cluster or a supercomputer. The latter is a system Extremely powerful which can be built with processors specially designed to reach extreme calculation powers or, most commonly common, from thousands of high performance servers. They are used for scientific simulations and tasks that require a huge calculation process, and its cost is brutal. On the other hand, We have the “affordable” version of a supercomputer: the computer cluster. It is a series of interconnected work stations that work in parallel solving problems. It is similar to a supercomputer, but the advantage is that It is a more flexible system Because, as you need more teams, you can expand the cluster. In addition, the components are more standard, which also allows the cost to be lower. But well, it is a concept that has blurred in recent years. The 100,000 club. That said, let’s go back to the graph elaborated by Visual Capitalist With the data of EPOCH AI. In it, we can see the most powerful clusters currently, but with some trap: they are both planned and operational. X, Elon Musk’s company, lit the XAI Colossus Memphis Phase 1 last year, a huge data center with 100,000 NVIDIA H100 GPU With the aim of training ‘Grok’, his AI model. It was something that He even surprised Jensen HuangCEO of Nvidia. It is a computing monster with an enormous calculation power, but the figure is expected to increase up to 200,000 GPU. We will see later the energy consequences of this. Following Musk’s company, we have Meta by stating that they have a cluster “greater than 100,000 GPU H100“For her model ‘calls 4’. Then there are those who maintain something else the mystery. For example, Microsoft with its cluster For Azure, Copilot and the OpenAi AI estimated they have 100,000 GPU between H100 and H200, Two worlds. Out of that 100,000 club we have Oracle With its 65,536 NVIDIA H200, another Musk company -you with the Cortex Phase 1 and its 50,000 GPU, and the United States Department of Energy with The Captainhe Most powerful supercomputer in the world. Officers or estimated, what is clear with this graph is that there is a country that has taken the calculation of AI seriously: United States. They are the ones that seem to push stronger with their data centers in the United States (of the 10 clusters, the first nine are in the US and the last in China) and are not only building inside their borders: Also outside. An example is the finish plan for Build data centers in Spain or the one who has practically Manhattan’s size. European expansion. In the graph, we can see two European clusters. On the one hand, The Jupiter from the Jülich Supercomputing Center in Germany with its confirmed GPUs. On the other hand, the Nexgen In Norway, with about 16,300 GPUs. Europe has undertaken several financing initiatives with the objective of Promote your competitiveness Thanks to programs such as Genai4eu and its budget of 700 million euros between 2024 and 2026. The objective is to build large data centers and, for the call of 2025, 76 proposals were presented in 16 different countries. Now, that development of the European AI must be aligned with Ai actthe agreement in force since February of this 2025 that ensures transparency and an ethical AI. Number vs. efficiency in China. Who has put the batteries in AI, beyond US companies, is China. Following one Road map very different from the westernChina is focusing on having (supposedly) less GPU working, operating with greater efficiency, much lower costs than those of American companies and with equivalent results. Deepseek or the most recent Kimi They are two samples of it. Nvidia rubs her hands. And of all this battle for AI, there is a clear winner: Nvidia. As much as it may be, and beyond who has more or less GPU to do the job, the clear winner is Nvidia. In China it is not so clear due to the commercial veto, but the main world data centers use Nvidia’s architecture with their GRAPHS H100 Y H200. And that if we talk about “normal” cards for AI, since they have the B200 with four times the performance of H100. In fact, the company seems so focused on that AI career that would have neglected what led by AMD for years: Your players cards. Those are servers of Lenovo data centers. Companies seek to reduce the footprint reusing hot water after dissipation to, for example, fill pools or showers. Image | Xataka The planet, not so much. And the consequence of that expansion of the AI is that data centers not only need huge energy amounts To function, also water to dissipate the heat of the equipment. There is an important absent in the graph, Google, which also operates its data centers for AI and that, together with others as goal or Microsoftneeds nuclear centrals to feed its facilities. Consumption is so exaggerated that renewables are insufficient during demand peaks, Using fossil fuels like coal or gas ( esteem That, the 200,000 Colossus GPU consume 300 MW, enough to feed 300,000 homes) and, as we said, the Water use has become discussion material in the candidate territories to house new data centers. So much dissipation needs China to already Building at the bottom of the ocean. In Xataka | China wants to become AI world engine. … Read more

The most “walkable” cities in the world, gathered on a map with an overwhelming winner: Europe

by

Little by little, Europe has been expelling the car. It’s something that goes beyond low emissions areas: It’s almost cultural. The cities of the continent were designed tailored to the pedestrians in which the cobbled streets and the squares were usual and, although they have given way to the roads, that pedestrianization is coming back. And show that pedestrian power is this map elaborated by Visual Capitalist in which we see the 20 most passable cities in the world on foot. Spoiler: The 20 are European. The map. The data to prepare the map have been extracted from the study ‘A universal frame for inclusive cities of 15 minutes‘and the graph of The Economist And it allows us to visualize the average time that someone living in a city of 500,000 inhabitants or more has to walk to reach some basic service. These services or comforts include places such as schools, restaurants, stores or hospitals and, although cities must be scored to choose an order, the truth is that the average time is very, very similar among them. Average time. Thus, of the 20 most pedestrian or more passable cities on foot in the world, the first would be Milan (with an ideal center to walk, everything is said) and the last one would be Oslo. Of course, as we can see in the table that we leave below, the difference between them is not a nonsense: Milan 6 minutes and 24 seconds Copenhagen 6 minutes and 36 seconds Turin 7 minutes and 6 seconds Dublin 7 minutes and 24 seconds Lyon 7 minutes and 24 seconds Munich 7 minutes and 30 seconds Paris 8 minutes Marseilles 8 minutes and 6 seconds Genoa 8 minutes and 6 seconds Edinburgh 8 minutes and 12 seconds Berlin 8 minutes and 12 seconds Vienna 8 minutes and 18 seconds St. Petersburg 8 minutes and 18 seconds Bilbao 8 minutes and 24 seconds Bordeaux 8 minutes and 30 seconds MINSK 8 minutes and 36 seconds Stuttgart 9 minutes and 6 seconds Lille 9 minutes and 6 seconds Barcelona 9 minutes and 12 seconds Oslo 9 minutes and 30 seconds Characteristics. The European advantage over other countries and the characteristics that make cities more friendly to pedestrians are diverse. On the one hand, these big cities usually have historical centers that have been pedestrianizing or that were already. There are many examples, but cities like Amsterdam or Paris, among many others, They have gained ground to the car In recent years with more pedestrian areas of both the center and the school streets. Another important factor is that many of them were founded before the arrival of the car, so they were designed to reach everywhere. That is why there is a greater proximity to essential services and there is a green infrastructure such as squares, gardens and parks that are also inciting, in addition, to walk. On the other hand, public transport is also very developed, reducing the dependence of the private car. Advantages. There are many, but we can encompass them in one: health. Walking more and taking less the car implies that air quality improves because there is less pollution. Noise is also reduced, although these two factors are something that the electric car has potential to change. Having a more active lifestyle, it has positive consequences on health and the cardiovascular system and is something that promotes community life. Projects. All this has led to the fact that, as we say, Europe is friendly with the pedestrian, there are cities that are rethinking their urban model. In Spain, there are cities like Logroño that They have gained space to the car. Pontevedra is Another curious casewith 80,000 vehicles in the center in the late 90s only 7,000 in 2018. The idea is to have “15 minutes cities”And, although in Spain we already live in them, there are projects for large cities to be even more friendly. An example is the Supermanzanas of Barcelonahe XPANDE project of Burgos to convert 23,000 square meters into pedestrian areas, the regeneration of Bilbao, Valencia either Sevilleamong other large and small throughout the territory. Out of Europe? And, in fact, it is something that has been encouraged at European level. He WALKING PANEUROPE PLANor European Walking Plan, was an initiative to promote that pedestrian mobility throughout Europe, driven by common policies and focused on improving health. Outside Europe, then … there is everything. To find the first most passable city on the list, you would have to go down to 28th place, where Kyoto is. And, within the top 50, there are other cities that are not European such as Taipei, Katmandú, Taichung or Tokyo, all in the lowest part of the list. USA, Cochista region. On the other side of the end is North America. The United States and Canada are countries that have developed cities in a completely opposite way to European: prioritizing the use of the private car. The first on the list is Vancouver in 53 position and it is something that will be difficult to change despite the projects individuals of each city. The reason is that it is something cultural due to the urban design of its large cities, where suburban areas are They expanded big before and after Second World War and where the highways They won the ground to the neighborhoods very quickly, destroying communities and that model of “cities of 15 minutes”. Cities like Houston or Los Angeles They could not sustain themselves without the car, in fact. In the end, it is curious as, at least in Europe, the cities of the future seem to look at the past to recover a healthier and closest urban model.
