The United States knows that Venezuela’s subsoil is full of rare earths. The big problem is that he doesn’t know where

The announcement that American companies could access to Venezuela’s vast oil has reignited a much broader ambition of Donald Trump’s administration. Because the Latin American nation has something that Washington desperately seeks, something that China he has plenty. He crux It’s how and how much. Beyond crude oil. Yes, the “b” side of the North American “landing” in Venezuela also seeks to explore the mineral potential of the country as part of “the national security of the United States.” The experts they point out that, in addition to crude oil, there would be unverified reserves of critical minerals and possible large quantities of rare earths, key inputs for defense and technology. However, the lack of reliable data, doubts about economic viability and operational risks in areas with the presence of armed groups and mining illegality turn the objective into an enterprise. much more complex that the oil reopening itself, with significant environmental impacts associates to energy-intensive mining. The supply chain and the bottleneck. Even if the extraction obstacles were overcome, the decisive challenge appears in processing. The refining of rare earths is concentrated in more than 90% in Chinaa domain constructed for decades through subsidies, industrial expansion and lax environmental regulations. This position has made rare earths a sensitive point of trade tensions between Washington and Beijing, with export controls that have highlighted the fragility of American supply chains. The consensus among analysts is that this industrial and geopolitical advantage cannot be reversed quickly, so new deposits without their own refining capacity would contribute little to short-term strategic resilience. Why it is important. It we have counted other times. The classification of “critical minerals” covers a broad set of raw materials essential for the economy and security, from aluminum and copper to a specific group of 17 elements known as rare earths, essential for high-performance magnets, advanced electronics and military systems. Although these elements are not scarce in the Earth’s crust, their extraction and refining are technically demanding and expensive. In the United States there are efforts to develop domestic capabilities, but start-up times are often measured in years or decades, which explains the temptation to look for external solutions that, in practice, rarely offer immediate results. Geological potential and structural limits. It happens that, unlike other countries with confirmed reserves, Venezuela does not appear in international lists as a relevant producer of rare earths, an explained absence for decades of opacity institutional during the governments by Hugo Chavez and Nicolás Maduro. Still, the country is believed to host deposits of coltan and bauxitesources of metals considered critical such as tantalum, niobium, aluminum and gallium. Projects like the Orinoco Mining Arc They sought to capitalize on that potential, but have been marked by illicit mining, lack of investment, a shortage of qualified labor, and a volatile regulatory environment that discourages international operators. A strategic mirage in the medium term. If you like, the final evaluation of the experts is clear: although the Venezuelan subsoil may hide valuable resources, its contribution to the security of supply of the United States it would be marginal on the near horizon. Without solid geological data, without security guarantees and without processing capacity independent of the Chinese circuit, Venezuela’s mineral interest seems more an extension of the geopolitical pulse than a practical solution, at least in the short term. In that context, the American bet faces a paradox: the country offers a lot on paper, but little that can be translated into real advantages over the next decade.

Stop importing gas and turning your subsoil into the new energy strength

While Europe monitored its gas deposits at the beginning of September –at 76%, a breath to the winter that is coming-, at the other end of the Chinese world he wrote another story. Far from the preventive mentality, the Asian giant is extracting gas at an unprecedented rate. It is not just about filling warehouses, but about rewriting the rules of your energy safety. The awakening of a gas giant. China was already a power in energy matters: storing oil and An undisputed leader in renewables. But now a new identity is carved: being a gas axis. In just twenty years, Beijing has achieved what few believed possible: turning from an almost absolute dependence on imports towards unstoppable rising domestic production. According to analyst John Kempinternal gas production has not stopped growing at a rate close to 10% per year since the beginning of the century. The provinces of the Northwest –xinjiang, Shaanxi, Interior Mongolia– They have registered Even more vigorous increases, 13%, while the Sichuan basin, more mature, maintains a remarkable 9%. Three main levers. The first bet has been the riskiest: getting where few arrive. The big state companies –Sinopec, Cnooc and Petrochina– They have reoriented their efforts towards wells up to 10,000 meters deep and the development of the complex shale gas in Sichuan. . It is not just a technical issue; It is a political strategy with a clear objective: to reduce the dependence of foreign gas, although that means drilling in hostile geological formations and a high cost. The second lever has been geographical. Secondary regions on the Chinese energy map, such as Xinjiang or Interior Mongolia, They have become the new gas engine in the country. With the determined support of Beijing, these areas now concentrate conventional and unconventional gas projects, backed by a logistics network that connects them with the east consumption centers. The third play has been geopolitical. China and Russia They signed a memorandum For the construction of the Power of Siberia 2 gas pipeline, an infrastructure that could inject up to 50,000 million cubic meters per year from Yamal to northern China. Although the price and calendar details are still on the table, the message is clear: Beijing ensures long -term supply, at probably lowered prices, and shields against the volatility of the global LNG market. The numbers do not lie. Official data collected by the Xinhua agency They reflect this turn. Between January and June 2025, China produced 130.8 billion cubic meters of natural gas, 5.8% more than in the same period of the previous year. In June alone, production reached 21.2 billion cubic meters, with a growth of 4.6% year -on -year. The International Energy Agency (AIE) Recognize that gas Win weight in the Chinese energy mix for its flexibility and lower emissions against coal, although it warns that the country must redouble efforts to meet its climatic goals. Meanwhile, liquefied natural gas imports (LNG) sink. According to the data of the KPLer consultant collected by BloombergLNG Chinese purchases will fall in September 22% year -on -year, up to 5.4 million tons. It is the eleventh consecutive month of descents. Reuters anticipates That total imports of 2025 could be reduced between 6% and 11%, weighed by a faster internal demand, the increase in local production and the largest flows by gas pipeline from Russia and Central Asia. Infrastructure for Independence. China is not only extracting more gas; also has woven a colossal network submarinto consolidate its autonomy. The Asian giant already exceeds 10,000 kilometers of underwater pipes, a web that connects gas platforms, wind farms and refineries with the terrestrial network. Emblematic projects such as the Bay of Hohai or the Deep field No. 1 symbolize this new energy border. These pipes transport gas and raw, and in the future they are called to carry hydrogen. The goal is not just technical; It is strategic: to ensure national supply and reduce exposure to international fluctuations. Forecasts The IEA provides that Chinese gas consumption reach its peak by 2035, before stabilizing with electrification and renewables. In the short term, the demand will remain moderate: the lazy industrial growth and the impulse of domestic production could maintain the imports of minimums also in 2026. Meanwhile, investments in deep perforations, the offshore network and the Russian gas pipelines consolidate China as self -sufficient actor and strong negotiator against traditional producers such as the US, Qatar or Australia. The new board. Europe keeps gas to survive winter. China, on the other hand, cava deeper to not need it. In just two decades, the country has gone from depending on metaneous cargoes to negotiate from abundance. If the plans are fulfilled – more national production, pipes until 2030 and Power of Siberia 2 operation in the next decade -, the global map of natural gas could definitely turn to Asia. And the old continent, which today breathes relieved with its full reserves, could soon discover that the next energy crisis will not be decided in Moscow or in Doha, but among Beijing’s offices.

The subsoil of historical cities hides a great garbage vacuum. The problem is that you have to punch

Tony Soprano, from the great series’The soprano‘He was dedicated to garbage management. It may seem an exaggeration designed for fiction, but as usually happens, fiction surpasses reality. Base management It is a problem for half the world (more now than China decided to stop being our landfill) and move so much money that there is mafias moving from one country to another. In the search for solutions, the definitive company came up with a Swedish company to stop seeing cubes and garbage trucks through the streets: move waste from pipes. It is something that has turned medieval cities into the technological pinnacle of garbage collection. But the day -to -day life of the neighbors is something else. Changing the approach. It all started by chance. At the end of the 1950s, the Sollefte hospital in Sweden was investigating the creation of a central aspiration system to catch dust. One of the participants in the table was OLOF H.Hallstrom, director of Centralsug, the current Waste Waste company, and the idea arose: instead of a giant vacuum For dust, a giant garbage vacuum could be created. So They tell On its website, where they point out that the system was inaugurated in the hospital in 1961 and that it continues to work with many of the original pieces installed more than 60 years ago. But of course, if it works so well in a building, why not expand the network to an entire city? That is no longer so easy. Sollefte basements with garbage collection tubes A giant vacuum. First of all, you have to see how it works. Known as’Pneumatic garbage collection‘O’ Automatic vacuum collection ‘, AVAC from now on, is a giant vacuum connected to a multitude of underground pneumatic tubes. On the surface there are a series of nozzles that are designed for organic or plastic waste (the glass could damage the system) in which the bag is deposited with the waste and, thanks to fans that generate suctions of more than 60 km/h, travel through the tubes to a collection center. Example of one of these nozzles They are classified and loaded into trucks to transport them to their final location. This system reduces the use of trucks and their corresponding pollution, as well as Cubes in the streets. The most current systems include doors that are automatically open and cards in possession of citizens to activate the system. Modernizing historical cities. And that reduction of cubes and trucks circulating is something ideal for any city, but it seems key in locations with two profiles: tourist or old helmets of medieval cities. A clear example is Bergen, a Norwegian city founded in 1070 that is the second most populated in the country and has a historic center full of colorful wooden houses. It has fired several times and the garbage itself can be a focus of fire, so by safety and improve the helmet, they decided to bet on an avac type system. It is one of the 200 cities in the world in which this system has been installed and, as we read in The Washington Postthe diesel emissions Since the garbage trucks stopped circulating along their narrow streets. Among others, Leganés, Barcelona, ​​Barakaldo, Torrent, Vitoria-Gasteiz, Stockholm, Doha or Seoul have neighborhoods in which a pneumatic collection system is used, and in new construction complexes of some cities are also betting on it. Complex. The problem is what you can imagine: the system itself is expensive, but it is also a headache. In new neighborhoods, it is as simple as to pass one more pipe in the streets where there are already other pipes, but in Historical cities Or neighborhoods already built, bet on something like avac implies lifting the streets and performing a considerable work. Bergen’s example is clear. As they point out on TWP, since they made the decision to start building the system in the historic center in 2007, they have invested about 100 million dollars. There are years to finish connecting the entire network and estimate that the cost will be 30 million dollars. Terje Strom, responsible for waste management in the city, says it is “almost impossible.” Contextualizing the figures? It is almost the entire annual budget of the Waste Department. Collection Central in Konza Technolopis, Africa Gamification and penalty. But, leaving cost aside, user experiences seem positive. It is a system that simplifies the garbage, which eliminates full cubes and the truck transit. In Spain we have containersbut in other cities they work with individual cubes that roll through the streets and share the stamp. Not everything is perfect, since although there are no trucks, they do operators who are dedicated to unblocking the mouths when someone introduces something that should not. And beyond not seeing garbage trucks, there are two incentives for citizens. One is the gamification by application That tells us how many kilos we have deposited in real time and compares with the previous month. It also tells us how average we are, since there is a limit. In Bergen, to open waste mouths, residents bring their electronic key, which allows you to register how much discard and collect a rate according to the amount of non -recycled garbage they send to the incinerator. This penalty is something that It has also been seen in South Koreawith positive results regarding the increase in recycling. Not everyone is happy. Beyond installation costs, it seems the perfect system to manage waste. However, looking at what happens in Spanish cities in which these systems have been installed, we see that not everything is so beautiful. There are more than thirty cities that use this pneumatic collection, and in some Failures are reported that cause the tubes to be full due to pipes that do not absorb well. Tubes in a kind of garbage rooms in Leganés. The main problem for users is the diameter of the mouth. Image | Xataka It is something that causes bad odors, as users of … Read more

Madrid only produces 4.8% of the energy it consumes, but has found a place to solve it: the subsoil

In 1980, a group of geologists set out to investigate the depths of Madrid and I did not speak of the Movebut discover if under its soil there was oil. The black gold fever had reached the Castilian plateau. However, what seemed like a dream of energy self -sufficiency ended up opening the door to unexpected energy. Today, that story continues to be written, but with a turn that nobody anticipated. The search. One of the first and most serious drilling attempts was the one made by Shell in 1980 in the well known as “El Pradillo-1” where no hydrocarbons were found. At that time the Spanish capital dreamed of becoming an oil city attentive to the prevalence of fossil fuel above other alternatives at that time not yet sufficiently exploited. More than 3,500 meters deep, engineers did not find oil but very valuable data about the subsoil temperature, which gave rise to the exploration of geothermal energy. Thus, They found a geothermal aquifer with temperatures between 70ºC and 90ºC at depths that range between 1,500 and 2,150 meters. Over the years, More perforations were performed In nearby areas, such as three songs, San Sebastián de los Reyes and Geomadrid-1, where multicapa aquifers found with temperatures to produce geothermal energy. Although exploitation has not yet been developed on a large scale, investigations continue, and this renewable resource is expected to be used in the future as an alternative energy source in Madrid. Among the pros of this discovery, intrinsic characteristics of this type of clean energy that are based on the use of heat stored in groundwater stand out to generate electricity and for homes. But why isn’t it exploited? Despite the discovery of a significant geothermal potential in the Madrid subsoil, the exploitation of this energy source has not yet developed on a large scale Due to several factors Among those that include, in the first place, the high cost of initial investigations and perforations, the infrastructure necessary to take advantage of the heat of the subsoil efficiently, such as the construction of geothermal plants and water reinjection systems. Energy comes from other communities. Madrid only produces 4.8% of the energy it consumes. This fact only represents the urgency that the Autonomous Community should have to resolve the scarce of alternatives to meet its domestic demand. At present, the ranquin between the communities that more depends on the energy of other areas. If the Madrid region will diversify its energy mix through the use of geothermal energy, not only would it increase its self -sufficiency, but also contribute to a more balanced energy model between the different autonomous communities with economic redundancies throughout the country. In addition, it would lead to rethinking The installation of data centersamong other alternatives, and would reduce Energy generation concentration In certain areas of the country, the pressure on energy transport and distribution infrastructures, which would benefit the entire national energy system by reducing the carbon footprint. The forecasts. With the progress of drilling technologies and improvements in thermal use systems, such as geothermal heat pumps, Madrid could already be able to begin to take advantage of their geothermal resources more efficiently. This is what the Basque Country has done with Geothermal rings at the university. Another possible alternative is to take an example to Iceland, which has turned geothermal energy at the base of its energy model, representing 66% of the total primary energy consumption of the country.
