NVIDIA already has its own Autopilot. And Tesla has reason to worry

NVIDIA has presented at the CES 2026 Alpamayo, a family of open source AI models designed specifically for autonomous vehicles. The system not only detects obstacles and plans routes, it “reasons” about complex situations and explains your driving decisions. Mercedes-Benz will be the first to implement it in the CLA, which will arrive in the United States in the first quarter of 2026. Why is it important. Tesla has kept its FSD system completely closed since 2016, and now NVIDIA is betting on releasing the weights of the model, the framework of simulation and more than 1,700 hours of driving data. This strategy can make NVIDIA “the Android of autonomous mobility” and allow any manufacturer to access capabilities comparable to Tesla’s without requiring years of internal development. The contrast: Tesla sells its FSD as a proprietary system integrated only into its cars, generating recurring income from your own clients. NVIDIA wants to sell chips to the entire industry, providing the base technology for others to build their systems. The first model earns more per individual sale, but the second can scale exponentially if multiple manufacturers adopt the platform. In detail. Alpamayo 1 is a 10 billion parameter model that processes video and generates both a trajectory and the logic behind each decision. Jensen Huang has described it as the “ChatGPT moment for physics AI.” The Mercedes CLA will integrate 30 sensors (cameras, radar, ultrasonic…) and will be marketed as a “Level 2+” system, similar to Tesla’s FSD in that it requires constant attention from the driver. Between the lines. NVIDIA’s move seems really good from a regulatory point of view: By generating a “reasoning traceability” that explains every decision, it reassures regulators who are often terrified by black-box models. And by releasing the code, it hooks startups and manufacturers in your CUDA ecosystem. If you can’t develop autonomy yourself (most traditional manufacturers can’t), you just use Alpamayo… and run it on NVIDIA chips. The threat. For Tesla, this means the dreaded commoditization of a technology that has been its main differentiator. If Mercedes delivers FSD-like capabilities in March based on a system that any brand can buy, Tesla’s sales pitch weakens. Elon Musk You have already commented on this announcement on your X profile: “It’s easy to get to 99%, then it’s very difficult to solve the rest.” It also seems like an implicit admission that Tesla hasn’t solved that final problem either. Yes, but. Open source does not guarantee success or similarity with Android in telephony. Actual implementation, integration with specific sensors and validation in real conditions remain complex. Tesla has been accumulating millions of kilometers of driving data for years. NVIDIA offers 1,700 hours, a tiny fraction in comparison. The question is whether that data advantage for Tesla offsets the distribution advantage NVIDIA can get by partnering with multiple manufacturers. Time and the market will tell.

let’s start traveling on foot

“It is common in Europe.” With these words, Óscar Puente, Minister of Transport, justified the possibility of traveling standing on medium-distance trains. Puente referred to this possibility in Twenty-something hourprogram of the Chain Being. There, it was assured that the Government is studying this possibility and 2026 aims to be key to carrying out a new way of traveling. “It is not being done”. And it is totally true. Puente pointed out in the aforementioned program that on medium-distance trains in Spain you cannot travel standing. And as in France or Portugal, it is prohibited to use regional trains without reserving a seat (as long as Renfe does not say otherwise, as we will see) so you can only stand in the spaces between carriages or in the area relative to the cafeteria. At that moment, Puente took the opportunity to announce that Renfe welcomes the proposal and that they have on the table launching a pilot test on a short line, one that is not particularly long. In Xataka We have asked Renfe about this possibility but they have not given an answer as to when this pilot test would be launched or where. They assure, in this case, that the decision belongs to Transport. Logroño-Zaragoza. The origin of the statements must be sought on the line between Logroño and Zaragoza passing through Pamplona. There, passengers have seen how medium distance trains have been replaced by Cercanías’ own vehicles for shorter trips. This caused some passengers to have to make the trip standing since there were no seated seats available, since the trains had a smaller number of seats. Already in July 2024Puente pointed out that this was something that had to change. In September 2025Renfe announced that new trains were arriving for the route between Logroño and Zaragoza, with a greater number of seats and cafeteria service since the new vehicles prioritized capacity over this option. Can you travel standing for medium distances? Technically yes, as long as there are any of the circumstances that Renfe points out on its website: Medium distance services without reservation Trains that stop at stations without sales, in which the traveler must buy the ticket en route: since it is not possible to reserve a seat, it is possible that there are no free seats. Travelers who have boarded without a ticket and have to regularize it en route, if at that moment there is no free seat. As an exception, on trains with the right to a seat, if Renfe so determines. And on the company’s own website, two cases are specified in which it is common to travel like this in our country. The first is the regional trains of Catalonia, as Puente pointed out in the Cadena Ser interview. The other is the possibility that a Cercanías train is being used for a medium-distance service, which is exactly what has been happening in Logroño-Zaragoza. In addition, it is specified that “travel insurance is assigned to the ticket, not to the seat. That is, every traveler with a ticket travels insured, regardless of whether they do so standing or sitting.” Europe. In his speech, Puente already pointed out that this is common in some European countries. Although the Minister did not then indicate which trains he was referring to, the truth is that in the Netherlands, Switzerland or Belgium they offer the sale of trains in which a seat is not assigned unless they are indicated. In the countries where this possibility is available, it is because travelers usually make relatively short regional journeys. So, for example, in Germany You buy a ticket for a regional train and the seat reservation is an added bonus. Something similar happens in Italy where their regional trains do not have an assigned seat unless you opt for their first class. And where is the advantage? Mainly, there are two advantages to the service. The first is that if this option is offered, the volume of passengers traveling on each train can be greatly increased. Of course, Renfe would have to use modified trains or versions more similar to those of Cercanías to be able to offer this service. The second is that, as in Italy, the train ticket schedule is flexible. For example, in Italy a travel day is allocated but you can take the train at any time you prefer. In other cases, a time is selected and that same train can be taken in an open time window before and after the original time, which makes the possibilities for the traveler more flexible. Obviously, this requires the train to be able to accommodate a number of passengers that exceeds the seating capacity, so if the seat is not reserved in advance, it is possible that the passenger travels the entire journey standing or has to get up at some point to leave said space for another passenger.

give a twist to Quantum Dots

TCL has been one of the leading proponents of democratization of MiniLED panelstechnology that it has carried to its entire range from 2025. Therefore, it has not surprised anyone that in 2026 it maintains its commitment to this technology. However, your proposal is different from Samsung either Hisense that are committed to changing the backlight matrix with Micro LED RGB systems. TCL has presented at CES 2026 a new technology called SQD-MiniLED that promises to change the landscape of high-end televisions. The proposal consists of combining the Mini blue LEDs with improved quantum dots to maintain brightness. that Mini LED screens provideapproaching the color purity of OLEDs. SQD-MiniLED: Vitaminized Quantum Dots by TCL TCL’s new technology focuses on the quantum dot filter responsible for breaking down and filtering the white or blue light emitted by the MiniLED diode array. The SQD that has been added to the name of this technology refers to Super Quantum Dot (or super quantum dots), the filter that contains the Super QLED Crystalswhich represent an evolution in the performance of the QD filters used in their televisions today. As the brand explained, the improvement in color volume of this technology is notable. Conventional MiniLED televisions reach approximately 83% of the BT.2020 color space, while the new X11L SQD, the only TCL television that will mount this new system, promises cover 100% of BT.2020. That means purer colors and a more complete visual palette. In addition, the new light filter is complemented by a new UltraColor filter with ultrafine particles (5 nanometers) that carries out a second filtering pixel by pixel, thus avoiding color interference and reducing the effect blooming (that halo that appears around bright objects on dark backgrounds, like subtitles). More dimming zones, more light control However, the development of the SQD filter for MiniLED is not the only improvement that TCL proposes to improve the image quality of its future televisions. Most high-end MiniLEDs offer between 1,000 and 5,000 local dimming zones, which is not bad at all. The X11L SQD, on the other hand, multiplies that figure up to 20,736 dimming zones for the 98 inch model. This increase is also supported by a 26-bit backlight controller capable of managing millions of control points, what TCL calls Precise Dimming Series. This combination is important because more dimming zones mean tighter control over which parts of the screen should brighten and which should remain dark. When you view a scene with stars against a night sky, that granular control allows the stars to shine without the glare spreading to dark areas. This is what allows us to combine deep blacks similar to those of an OLED, with peaks of extremely high brightness. The X11L SQD that TCL has presented as a test table for its latest technologies reaches the 10,000 nits maximum brightnessthe upper limit allowed by the Dolby Vision HDR standard. The combination of 20,736 dimming zones, together with 10,000 nits of brightness and 100% BT.2020 coverage, results in blacks controlled with extreme precision and a wider color volume than those currently offered by conventional MiniLED televisions. However, improving the panel’s performance does not imply an improvement in itself if that improvement is not well managed. Hence TCL has developed the new TSR AI processor with Super Resolution to manage the new capabilities of your SQD Mini LED panel by applying AI algorithms. The TCL will arrive soon to the United States and will start at $6,999 for the 75-inch models, increasing to $7,999 for the 85-inch version and $9,999 for the 98-inch ones. The brand has not confirmed its arrival in Europe and Spain, nor its price for the old continent.

The fifth season of ‘Stranger Things’ is the worst of the series by far. Netflix doesn’t care

Few series better illustrate the dissociation between popularity and prestige than the fifth season of ‘Stranger Things’. The numbers are overwhelming: the closing of the saga accumulated 105.7 million views on Netflixconsolidating itself as the ninth most viewed English series in the entire history of the platform. However, the critical reception and even some increasingly disappointed fans With the conclusion they leave the franchise in an uncomfortable no man’s land that, for the moment, refuses (very much) to die. Audience bomb. The numbers are impressive: the conclusion of the last season propelled Netflix to its best viewership on a New Year’s Day. Furthermore, in an unprecedented experiment, the platform released the final two-hour episode in theaters and raised $25 million at the box office in just 48 hours. It was a very limited distribution of only 600 rooms, in a period of 36 hours and without traditional ticket sales (20 dollars in food and drink were purchased that gave the right to a seat), due to the actors’ royalty contracts: the collection was entirely for the theaters of the chain that had exclusive distribution, AMC. And critical disappointment. On Rotten TomatoesFor example, the audience score has suffered an unprecedented drop in the franchise: from 96% for the first season in 2016 to the current 54% for the fifth, after 90% for the second, 86% for the third and 89% for the fourth. It’s a forty-point drop that reflects more than just viewer fatigue. TIME He explained it in an article about the phenomenon: in 2016 the series was an irresistible nostalgic toy. Nine years later, it’s a content factory. Nine years ago it redefined streaming and entertainment; Now he is another victim of Hollywood franchise machinery. Why didn’t you like it? The criticism of the fifth season is not limited to the disappointment of the fans. It has been said that the series has failed to delve into its characters as they grew. In the technical sectionit has been commented that it is a sloppy production, in the worst Netflix style: excessive lighting, abuse of background blur, obvious color schemes… The aforementioned TIME article also alluded to its pace, with an excess of exposition and verbalization, since this season is the conclusion of a decadent trend for the series that started in season 4. Critical point. The episode in which all these tensions crystallized It was the penultimate of the series, whose IMDb score plummeted to 5.4 out of 10, becoming the lowest rated episode of the entire franchise, and the only one below 7.8, when most episodes range between 8.6 and 9.2. The episode accumulated more than 96,000 ratings, double that of the rest of the season’s episodes, which is why it is suspected of a campaign of review bombing due to its central scene; In any case, some of the criticism pointed to legitimate writing and pacing problems. The unstoppable franchise. If the quality has dropped, why does Netflix insist on milking the series? The answer lies in analysis as this parrot which speaks of more than a billion dollars in revenue since 2020, that is, not counting the first three seasons. To this we must add more than two million new subscribers directly attributable to the franchise. And above all, something intangible: the series consolidated the current model of streaming and gave Netflix executives confidence that they could launch franchises capable of competing with rivals like Marvel. What does it grow with? The company has designed an expansion plan that will keep the Hawkins universe alive for years. The first major spin-off was a play (‘Stranger Things: The First Shadow’), which premiered in London’s West End in 2023 and jumped to Broadway in 2025, exploring the origins of Vecna ​​and the first experiments of Project Indigo. ‘Tales from ’85’, an animated series set in the winter between the second and third seasons, is planned for 2026. The main characters (Once, Hopper, Mike, Dustin, Lucas, Will, Max) will return in an animated version, which will allow you to touch with your fingertips that impossible treasure that is that children never age. Beyond animation, Netflix is ​​developing an as yet untitled live-action spin-off that will rethink the series from scratch: new characters, probably another decade, and without directly entering the Upside Down. It will work more as an anthology connected to the mythology and tone of the original than as a typical sequel. To this we must add the comics, which Norma Editorial has published in Spain since 2018, immersive experiences in Abu Dhabi and Mexico City, collaborations with Fortnite and extensive merchandising. And although the Duffers have an exclusive contract with Paramount, they will maintain creative supervision of everything related to the series. The underlying problem. With the conclusion of ‘Stranger Things’, Netflix is at a strategic crossroads. There is currently no original production on the platform that is so attractive and, above all, so generationally transversal, something in which ‘The Squid Game’, ‘Wednesday’ or ‘The Bridgertons’ fail. As El País points out, one of the reasons why Netflix has shown interest in acquiring Warner It is precisely because of the need to access a catalog of expandable properties in the style of DC, Harry Potter or ‘Game of Thrones’. The machine does not stop or wait for anyone. In Xataka | The best Netflix series that you can currently watch on the platform

600km and charges in 10 minutes

The world’s first motorcycle with a solid-state battery is now a reality. Is called TS Pro and the Verge factorya small Finnish brand. Its promise is clear and disruptive: up to 600 km of autonomy, a figure higher than that of a Tesla Model 3 standard. A record. Talking about 600km of autonomy is not only a record within the still young electric motorcycle market. It is a fact that breaks the current framework of the entire motorcycle industry. The average range of a medium or high displacement motorcycle today is around 300 km, which means that, for the first time, an electric motorcycle not only equals, but far surpasses combustion in one of its great bastions. Although there is quite a bit of fine print to read. The data. The TS Pro from Verge is a 100% electric naked that accelerates from 0 to 100km/h in 3.5 seconds and with a torque of 1,000 Nm. To give you some context, the fastest motorcycles ever made in the world barely exceed 100nm. But the key is not only in the excessive power, it is in the barriers it breaks. 600km of autonomy Weight of “only” 235kg Quick charge in 10 minutes CSS Loader Five-year battery warranty There is nothing like it. Currently in Europe (and specifically, in Spain) there is nothing remotely similar to what Verge offers. The reference electric motorcycle is the Zero SR/F Streetwith a range of 283km. The rest of the attempts to democratize the electric motorcycle, such as Harley with LiveWirehave remained at ranges of between 150 and 250km. Not even in price. Between 40,000 and more than 50,000 euros. This is what it will cost to get this electric motorcycle in Spain. It is not an unreasonable price, taking into account that proposals like those from Zero are around 30,000 euros with noticeably lower specifications. If you’re wondering “what about maintenance”, it’s relatively similar to that of a Tesla. Verge will offer a remote customer service for any type of question or problem and, in the event of a breakdown, they will have a home service to carry out the necessary maintenance on the motorcycle. According to the brand, these motorcycles only need one service a year. The paradigm shift. The “it has half the autonomy of a diesel” in the car world translated to “it has half the autonomy of my motorcycle” in the world of two wheels. This Verge is important not only for introducing solid-state technology in the sector, but for demonstrating that the electric motorcycle can double the autonomy of its combustion alternatives. The resistances. Verge faces resistance that goes beyond the technical sheet and cold numbers: the motorcycle market is a passionate market. Even so. Despite the unknown of what is going to happen with the future of the motorcycle, Verge has taken a giant step. An unknown company has been the first to introduce solid-state batteries and to demonstrate that the autonomy barrier will not be the slightest problem in the future. Meanwhile, Japanese giants like Honda have not managed to exceed 130km of autonomy in its new generation of electric motorcycles. China’s landing in Spain and Europe It is being an overwhelming success: The first manufacturer that manages to offer solid state at an affordable price will have everything to win.

Offering the cheapest gasoline in Spain has become an obsession. And 2026 is going to be the year of the great battle

The cheapest gasoline in Spain today, January 7, is found at a Ballenoil service station in Coslada (Madrid) at a price of 1,239 euros/liter, according to dieselgasolina.coma portal that monitors the price of service stations throughout our country. The second position is also from a Ballenoil service station and is also in Coslada. And the third. And the fourth and the fifth. Oh. And also the seventh, the eighth and the tenth. And the company low cost has started a war to be the company that sells us fuel the cheapest in our country. It wants to continue expanding. And along the way it will face Plenergy, another of the queens of cheap gasoline. Both have undertaken strong expansion. The cheap gasoline war Ballenoil, which is part of Cepsa moeve since just over two yearsis the leg that its parent company has to continue attracting customers who prioritize the price of gasoline above any other incentive. The company goes through a transformation campaignmaking greater efforts for sustainable fuels and electricity. With Ballenoil, Moeve has some safety net. Its service stations require very little expense because, precisely, that is the secret of gasoline low cost. Minimum investments in the stations, forget about additives and any other additional service so that word of mouth is the true driver of service stations. Low prices but good performance at volume. The strategy is working. They point out in Five Days that Ballenoil sold 1.385 million liters of fuel in 2024 and that the target figure for 2026 is 1.8 billion liters. To do this, they seek to consolidate at the end of the year an offer of 500 gas stations spread throughout Spain. Last November they were the first low cost to reach 350 stations of service in Spain. The investment is by no means exceptional. Plenergy is another of the kings of low cost with a turnover of 1,550 million euros in sales in 2024. Right now, it has 352 gas stations on the Peninsula, of which 10 are in Portugal and the rest in Spain. The objective is the same as that of Ballenoil: 500 service stations by the end of 2026. He growth of this type of business It is so high that if the plans are fulfilled we will be seeing one opening of this type of company every four days. That is, every two weeks there should be three new service stations and another on the way. And to certify it, the objective of Plenergy, they point out in Five Days is to have a 10% market share in our country. That would place it as the third most used company, only behind Repsol and Moeve. To these two giants we must add the third in contention. Petroprix, which shares with Ballenoil the service stations with the cheapest fuel in Spain according to dieselgasolina.com, also plans an expansion. For now, talk about extend your influence abroad But it also does not turn its back on Spain and talks about having 400 service stations ready in our country by 2027. gasoline low cost proves to be a huge business in our country. As we counted on Xatakaits competitive advantage is zero investment in marketing or additives. The fuel arrives at these service stations as it is distributed by Exolum, former CHLin charge of distributing all gasoline throughout our country. In return, the business model proposes sales that are large enough to compensate for the narrow profit margin, without an alternative for additional services such as large gas stations such as Repsol or Moeve receive.

The gold of the 21st century is not in Venezuela. China and Russia know it, and that is why the US wants Greenland no matter what.

As if it were a Deja Vú2026 has exactly begun same as 2025: with Trump’s insistence on take over Greenland. It happens that it no longer seems like an isolated whim or a rhetorical eccentricity, but rather the convergence of a personal drive, a strategic opportunity perceived as easy, and a high-impact geopolitical calculation. Venezuela It has served to light the fuse. Greenland as an obsession. After the capture of MaduroTrump confirmed once again that the use of force abroad lacks the legal and judicial brakes that do constrain his domestic action, and that, in the face of clearly outmatched adversaries or allies, the reality is imposed on international law without too many immediate consequences. Greenland then appears (again) as the perfect prize: a huge, sparsely populated territory, defended by an ally incapable of military resistance and located in an area where Washington can dress territorial ambition in the language of “national security”. The reiteration of the message, the appointment of a specific envoy and the public statements that normalize even the military option indicate that this is not a joke or simple diplomatic pressure, but rather an obsession that grows as Trump’s internal political margin narrows. The founding paradox of NATO. The central problem is that Greenland belongs to the Kingdom of Denmarka full member of NATO, and any US action against it would place the Alliance before a paradox for which it was not designed. He Article 5, designed to deter external enemies, does not see clearly What happens when the aggressor is the hegemonic member. As has warned Danish Prime Minister Mette Frederiksen, in that scenario “everything would stop”: NATO could continue to exist formally, but its credibility would be destroyed. No one would come to the defense of Greenland against the United States, not only due to a lack of political will, but also due to the absolute material asymmetry between Washington and the rest of the allies. The implicit message is thunder for Europe: security guarantees are no longer automatic, and force is once again in place above the treatyan outcome that directly benefits Russia at the moment of greatest tension since the end of the Cold War. Critical minerals. The economic and technological argument is supported in mineral wealth that lies under the Greenland ice, the result of an ancient geology that concentrates rare earths and other essential critical minerals for the energy transition. From the 19th century to today, different actors have tried exploit that potential, from Ivittuut cryolite during World War II to contemporary rare earth projects. However, the enthusiasm collides with a stubborn reality: extracting these resources is extraordinarily expensive, slow and risky. The almost total lack of infrastructure, the dependence on maritime or air transport, the complexity of processing (with minerals often associated with uranium) and restrictive environmental legislation mean that only a minimal fraction of exploration projects become operational mines, usually after more than a decade of investment. Extra ball. Furthermore, the memory of the environmental damage caused by past exploitations, whose effects are still detectable half a century later in extremely fragile ecosystems, explains why Greenlandic society only contemplates mining. like an opportunity if you actively participate in decision-making and project ownership. The loot exists, but it is neither immediate nor easy, and it certainly does not seem to be able to justify the American strategic urgency on its own. Hybrid war. The backdrop is a northern Europe increasingly militarizedwhere incidents against submarine cables, gas pipelines and critical infrastructure in the Baltic have normalized the idea of a permanent hybrid war. In this context, Washington observes how Moscow and Beijing test pressure tactics below the threshold of open conflict, while legal and judicial responses appear slow or ineffective. The explicit willingness of the United States to include military option for Greenland fits into that fait accompli logic: securing key positions before the strategic environment deteriorates further. It is not just about denying advantages to rivals, but about getting ahead of a scenario in which infrastructure, logistics and control of physical nodes are worth more than declarations of principles. The navigable Arctic and a port. Here a possible decisive derivative emerges. Science has been warning for some time a stage where the Arctic is heading, on a horizon of decades, to be navigable for most of the year. The sustained retreat of sea ice is transforming routes that were once seasonal into viable commercial corridorsdrastically reducing the distances between Asia, Europe and North America. Today, they capitalize on that advantage especially Russiawith the Northern Maritime Route, and Chinawhich presents itself as a “near-Arctic power” and invests in ports, icebreakers and logistics agreements. For the United States, which is late to this board, Greenland represents the perfect shortcut: an enclave located between the Atlantic and the Arctic, capable of hosting deep-water ports, air bases and logistics nodes from which to offset the Russian-Chinese advantage. Seen this way, more than a mine, Greenland is a port ahead of the world to come, a piece from which to influence the global trade of the 21st century and the control of routes that, for the first time in modern history, cease to be be closed by ice. A small island, a global change. If you will, the final paradox is that all this pulse revolves around a tiny territory of less than 60,000 inhabitantsone mostly opposed to integrating into the United States and in favor, at best, of a slow and cautious independence. However, its symbolic and strategic value is disproportionate. Greenland condenses the transition to a world where melting ice reconfigures maps, critical minerals redefine dependencies, and alliances are strained to the limit. For Trump, it is a source of political impact, potential money and demolition of the old order. For Europe, possibly proof that geography prevails again to the law. And for the international system, the warning that the Arctic is no longer a remote edge of the planet, but one of its new centers of gravity. Image | The … Read more

Physics is clear that it is a mistake

In the middle of winter, a classic dilemma always returns in Spanish homes: is it advisable to leave the heating on all day to avoid the “peak of consumption” when turning it back on or is it better to turn it off every time we go out? For years, fear of an astronomical bill has fueled the myth that “keeping warm” is cheaper. But this winter, experts have decided to settle the issue by relying on an unbeatable ally: the laws of physics. The five minute rule. For Jorge Morales de Labra, industrial engineer and energy analyst, the answer does not allow nuances. As explained in Cadena CopeTurning off the heating is always worth it. In fact, he exemplifies it very simply: “Even if you go down for five minutes to buy bread, it is economically worthwhile to turn it off.” This statement has a solid scientific basis. As Morales de Labra details, heating systems consume energy constantly to compensate for the heat losses that the home suffers through walls, ceilings and windows. If the heating remains on while no one is there, we are paying for a comfort that no one enjoys, forcing the boiler to work tirelessly to counteract the cold outside. So why does shutting down save more than maintaining? The key lies in demystifying the “effort” that the boiler makes when starting. Although it is true that the boiler works more intensely to recover the initial temperature, this specific consumption is much lower than the sustained expenditure to keep the system running during hours of absence. Furthermore, the figures support this thesis. According to data from the OCU (Organization of Consumers and Users)If we decide to turn off the heating completely at night, the savings can skyrocket up to 67%. For their part, energy efficiency studies cited by El Español They estimate that by simply turning off the system for short and moderate absences, a family can reduce their annual bill by 8% to 15%. In an average home, this represents a direct saving of between 50 and 120 euros per year. The “invisible limit” of 21 degrees. Another common mistake is to confuse comfort with excess heat. The Institute for Energy Diversification and Saving (IDAE) warns that Each degree we go above that threshold makes the bill 7% more expensive. The official recommendation is clear: During the day: Between 19 °C and 21 °C is the optimal temperature. At night: Simply keep it between 15°C and 17°C, or turn it off directly. It should be remembered that this rule is universal for radiators and heat pumps. Nevertheless, systems such as underfloor heatingwhich have great thermal inertia and take hours to heat up, require more stable management and do not benefit from shutdowns lasting just minutes. The crucial role of insulation. It’s not all the thermostat’s fault; The reality is that almost half of what we pay depends on the walls. If your house has leaks, heat literally escapes through the cracks, forcing you to turn up the heat to avoid shivering. It is a vicious circle that empties the pocket. Luckily, the International Energy Agency (IEA) suggests several effective patches that do not require getting into work: Seal drafts: Installing weather stripping on doors and windows can save up to 100 euros annually. Blind management: Open them during the day to take advantage of the sun and close them tightly at nightfall to add an extra layer of insulation. Adjust the boiler: It is recommended to lower the boiler delivery temperature (the water that goes to the radiators) to improve the efficiency of the equipment. Smart ventilation: Simply open the windows for a few minutes in the morning to renew the air without the walls getting cold. An investment in control. Savings do not come from being cold, but from managing the heat intelligently. Jorge Morales de Labra emphasizes the importance of smart thermostats. These devices allow programming the heating so that it turns on half an hour before we get home or turn it off from our cell phone if we have forgotten. In short, this winter science gives us permission to turn off the switch. Heating an empty house is not comfort, it is waste.
