Media Spain has gone crazy with the question of whether olives fattening or not. But its biggest problem is not calories

by

“Do olives fattening?” In recent days, this question has run like gunpowder online and should not surprise us. It is one of those things that becomes viral from time to time: it is a typical case of very common product at the gastronomic level, but deeply unknown at the nutritional level. Let’s see what the science of olives and the rest of the pickles say. An urban myth. As the nutritionist Pablo Ojeda pointed out a few days ago, the idea that “the olives fattening” is close to the urban myth. And not only because, in short, food does not fattening or thinning for themselves (that is something that has to do with the general caloric deficit and not a specific product). It is an urban myth because it arises from a truth: that, According to the Spanish Food Composition Database92% of the energy provided by an olive It is fat. It is the nutrient that they contribute most with a lot of distance on carbohydrates or proteins. And that (even if that fat is “good”) destroys the nutritional profile of any product. However, if we look at other parameters we will see that, for example, the caloric density of these products is not very high. That is, you have to eat many olives so that that contribution is really noticed. Is the same thing with the rest of the pickles? In fact, olives are surely the most caloric pickles. In general, these types of products have very few calories. Classic pepinillos have about 12 calories per 100 grams, onions about 30. In comparison, it is true that olives have a greater caloric contribution: 120 green and up to 289 blacks. The real problem is salt. Because seen that, it may seem that pipinillos are a nutritional jewel. And, although they do not have many calories, what is certain is that they are very uploaded. To get an idea, WHO advises that salt consumption Do not exceed 5 grams a day. Well, only pipinillos are 2.3 grams per 100. In a context in which salt consumption does not cease to rise (promoted, above all, by the ultra -processed), care must be taken because it is a very important risk factor of cardiovascular diseases. And the probiotics? Here is some confusion because, although it is one of the fashion themes, still We know very little about the microbiota of our digestive system. On the one hand, yes: there are traditional products that are fermented in brine and, indeed, these They can have microorganisms to help us with the microbiota (although either much). However, “pickles” comes to mean ‘conserving in vinegar’ and in that environment it is difficult for interesting probiotics to remain. Most of what is sold in the market, in fact, has none. Beyond, this is, we must remember that the evidence that sustains probiotics is still scarce. It is not worth obsessing with them because, in most times, Its impact on health is zero. What matters As we often rememberIt is wanting to eat better. Everything else is literature.

This is the smallest microcontroller in the world that opens “unlimited possibilities”

by

There is a career to inflate the numbers in the processors segment. Further millions of transistorsmore power, more speed (More consumption In the case of GPUs …). But there is also a career to make the components are getting smaller and while maintaining, or overcome, the power of previous generations. And the Texas Instruments company ends to pass the game with the MSPM0C1104. Because yes, what you see in the main image is the smallest microcontroller in the world. And their possibilities are very interesting. Microcontrollers. They are basically a small computer in a single chip. Without the need for a complex operating system, they can manage tasks by integrating the processor, RAM, and the EEPROM in the same unit. In addition, they have the necessary pins for input and exit signals, among other components. Raspberry Pi RP2040 is an example and are created to function with light systems and fulfill specific tasks. MSPM0C1104. With this name, Texas Instruments has baptized what, according to them, is the smallest microcontroller in the world. It has a size of just 1.38 mm². If you have a black pepper grain at home, you can get an idea of ​​what is the approximate size of this MCU. Specifically, the company comments that it is 38% smaller than the smallest MCUs of the competition. 20 cents. The truth is that it is shocking to see the amount of elements that have been able to unite something so small. It is based on Arm Cortex-m+ and account With a frequency of 24 MHz, 16 kb of memory, an analog-digital converter of 12 bit, six input/output pins and compatibility with standard communication interfaces. If they are purchased in 1,000 units packages, the chips have a price of just 16 cents and Texas Instruments offers a rapid prototyped hardware kit to facilitate development in their MCU, as well as tools to develop and execute MCU applications in a simple way without having to program. The MCU inside some headphones “Unlimited possibilities”. Now, we talked about power a few lines and surely those 24 MHz and 16 kb of RAM have squeak. This is not intended to run an operating system as they can do other microprocessors such as the aforementioned Raspberry Pibut it is something focused on other uses. The company gives the example of optical pencils or more advanced toothbrushes, but also comment that “the possibilities are unlimited to enable smarter and connected experiences in our daily lives”, putting an example headphones and medical probes. As this MCU is so small, these devices can maintain the current power by reducing the space that the microcontroller occupies on the plate, and other elements that improve the characteristics of the product can be added. That’s it? In the press release, the examples are somewhat scarce, but in a video that the company has shared we can see some uses beyond the ‘brain’ of headphones, a digital pencil or a medical probe. For example, such a small system can be introduced into the USB-C cable plate. Thus, if the size of the cable processor ‘is reduced, the connections or dissipation can be reinforced to make it more stable and increase its speed. Another very interesting example is the presence in the smart rings plate. Here they have a lot of sense because they are complex plates due not only to the size of a ring, but to the peculiar curved shape of it. And we return to the same thing: the less space occupies the processor of a ring, the more battery, for example, it can be introduced. In the end, the technical details of this type of microcontrollers are more interesting for those who want to toys with them and for device manufacturers, but it is always interesting to know that this race for size does not respond to a whim, but is useful to solve problems on the devices we use daily. Or for run more thingsclear.

Thousands of women are sleeping with a lot of masks and adhesive ribbons in the face: the boom of the "Morning Sheds"

by

The earth revolves around the sun and people around Tiktok, and where there is a trend there will be thousands of people repeating it. For a couple of months he has become fashionable all night with a lot of masks, patches and silk caps, among many more things. This trend has a name: Morning Sheds. A simple premise. There is an presupposition that when you leave a mask for longer, more effect does. However, this is not true. Each product has a certain duration that is usually detailed in the container itself, as well as expiration. In fact, dermatologists Beauty routines supportbut alert about risks to cover excess skin and use products without control. Thus a new viral phenomenon is born. According to Vogue magazine, already There are more of 75 million publications about Morning Sheds, And keep increasing. The objective of these people – mostly women – is to add to their facial ritual of the most cosmetics and gadgets nights. In Xataka Mercadona rejuvenation patches hide something else: the culmination of a long biotechnological career How much more better … There are many videos to analyze one by one, but among which We have been able to observe The same steps are always repeated. First of all, The night masks and patches for eye contour. After, he FACE TAPING, Adhesive ribbons that act as neuromodulators to “tighten” the skin. Third, the Mouth Taping, A tape that sticks in the mouth to encourage nasal breathing. It follows the curls without heat, thanks to the bandans, curlers or silk caps. Finally, as a species of gap and wraps with Cleaning oil for abdomen. The logic, if there is, behind this whole trend is that, how much more in contact is with the skin, the more effect it will do. However, reality is another. The possible risks. The theme of all this is the exhibition of these products on the face, we are talking about a very long use, a whole night. Hydration is necessary, but not an abuse as is happening in these cases. In fact, Dramatologist Dr. Purvisha Patel has explained for Vogue that covering too much the skin can cause outbreaks or make active ingredients lose effectiveness. As for the subject of FACE TAPING Using adhesive tapes on the face can be a great inconvenience, such as detail for GQ The doctor Candy Hernández. The dermatologist has described that this is a risk to the skin because it prevents it from transpiring, putting the epidermis in prolonged contact with adhesives and other substances whose composition could be harmful. For its part, the use of Mouth Taping It is a trend that claims to improve nasal breathing and sleep quality. However, Dr. Rybel Wix has sustained for chain to be that there is no scientific evidence that supports it. On the contrary, it can hinder breathing and fragment sleep, affecting rest. Without effects. Videos on Tiktok show people using bands to redefine facial contour and girdles with castor oil to reduce measures. However, Dermatologist Dendy Engelman has clarified for Womenshealthmag that there is no evidence that these methods generate permanent changes in the facial or body structure. In the case of hair, it is important not to tighten too much to avoid traction fall. {“Videid”: “X81YBHL”, “Autoplay”: False, “Title”: “Beware of beauty mode of some Chinese terminals”, “Tag”: “”, “Duration”: “191”} Are we facing a passenger fashion? Beyond its effectiveness, this trend is a reflection of the extreme commodification of self -care. He Morning Sheds It is a sample of how far the obsession for aesthetic perfection can go. While some habits can provide benefits, excess products and gadgets does not guarantee better results and, in some cases, it can be harmful. Before joining any viral trend, it is important to go to professionals who can help you find the best routine. But if I can give a small advice, even if we are in winter, you never forget the sunscreen.

In 2007, Better Place said to recharge an electric car in five minutes. This is the story of a loud failure

by

Nio and Catl have reached an agreement to implement the largest battery exchange network in the world. “The most extensive and advanced,” Catl announced in a statement collected by The avant -garde. The project comes from afar. In 2020Nio already presumed that he could change the battery of his electric cars in three minutes. Since then, we had not known the project beyond In 2022 The electric cars company made noise with this issue. By then, the competition seemed served. The Geely Group, also Chinese, assured that In 2025 5,000 stations would have deployed of battery exchange. But, again, little has been known again on the matter. Until Catl has decided to trust the child project, investing 314 million euros in its battery exchange system. But although they explain that they aspire to have the “most extensive” network, the truth is that no stations numbers data have been provided. However, Nio and Catl’s proposal is not alone. In China, other companies have also tried to standardize this system and Bloomberg He calculated in 2022 that for this year some 26,000 battery exchange stations in the Asian country would have available. It is clear that there is some interest in China in keep investing in the system and technology. However, everything indicates that if there are certain recharge times of byd and are economically viable their stations, A 400 km load in five minutes You can kill the concept. If so, the system would go to a better life. A system that has already been touched almost 20 years ago and that failed irremediably when, ironically, more fault. A little context with a battalion When a person tells me that an electric car does not serve to travel and, above all, he tells me that they will not be in a long time, I usually tell an experience. At the end of 2019 I participated a project to join all the provincial capitals of the Iberian Peninsula by electric car. It was about demonstrating that the network had advanced and that the second generation of Nissan Leaf was a much more capable car. Turning among colleagues, it was late as little as possible. We get it yes, but it is also true that the challenge took us Almost seven days Although we stopped just and necessary to recharge the car. We ate as the car was loaded and slept while the car drank from the plugs. I remember calling a gas station to ask please open a plug even though we arrived after the service station had closed. We had no choice. For Todo Teruel there was only one public charger available. That charger had to open with a key the employees of the gas station. They asked us that at the end we would leave the hidden key. Once the load was finished, Nissan’s electric should have almost 400 kilometers available on a 62 kWh battery. The truth is that we stopped every 200-250 km to take advantage of the fastest part of the recharge unless we would like to sleep in the middle of the trip. Today, in Teruel and its surroundings, there are More than 25 public plugs available according to Electromaps. A few kilometers from the city, next to the highway, one carries 100 kW. Two other closest plugs can load a maximum of 350 kW if your car admits it. That Nissan Leaf, tells us Km77it would have taken 90 minutes to go from 0 to 80% of the battery charge. Today, most cars with 60-70 kWh battery capacity would recover the load up to 80% in about 20 minutes. I count all this battalion because, believe me, if I had had a Better Place battery exchange station on hand, I would have used it. Too bad that when we got into that jaleo, the project had been dead for six years. In just over a five years, the electric car market in Spain has changed completely. And although the recharge network You have to keep improvingright now it is easy to travel to any point in the country if the car has more than 60 kWh battery capacity. The minimum required to travel if we are going to make the recommended stops every two hours or 200 kilometers. What happened to Better Place? We explained all this because it is important to know the context. Having an electric car and traveling with him makes just over a five years ago was a real headache. Now, imagine that you are in 2007 and someone has said that those cars that barely do 200 kilometers in the best case and take a whole night to load are the future. What would you think? You have to look for ways to reduce loading times. And that same idea had Shai Agassi. This Israeli businessman saw that there was a business road. The electric car began to make its way but without recharge points and with times of the same too extensive, the project was unfeasible. He decided that he would create something as simple and as groundbreaking as a battery exchange station. The theory was perfect on paper: you arrive with your car and you don’t have to worry about standing for hours. In a few minutes the car would be ready to travel another 150-200 kilometers. In practice, the car was something like taking it to a wash tunnel. You entered the station after saving a barrier. Inside, The machine extracted the car battery and “sealed” it with another already loaded. An auxiliary space was needed to recharge the batteries that were interspersed. The proposal received immediate support. Different investors came to put 650 million euros in total. In 2013 the company declared bankruptcy after raising just over five million euros. Along the way, yes, I had attracted Renault’s interest. The French company adapted its Renault Fluence to function as an electric car. He put the surname ZE and the car was compatible with the battery … Read more

The price of coffee lives one of the biggest climbs in its history. The UN thinks that the worst has not yet happened

by

They are not easy times. That is the summary when we have some Eggs in full price escalationthe triggered cocoa Due to illegal gold mining And a coffee that has achieved historical values. In the case of coffee we have been anticipating the storm for months, with a product that was Marking maximums in the stock market and with brands absorbing the coup until have stopped doing it. And, in the middle of that uncertain panorama on the price of coffee, the United Nations arrives to tell us that the worst has not yet been. What about coffee? A set of factors, actually. To the difficulties of transporting raw coffee, aggravated by the increase in freight due to conflicts such as the Red Sea, these last crops are added. Vietnam and Brazil are two great coffee producers worldwidebut the climatic phenomena known as the boy and the girl have affected coffee spots -coffee plants. Both phenomena affected similar forms to countries so remote, causing the same in both: higher temperatures and droughts in some producing areas, as well as an alteration of the rainy season that fall torrentially in a short period of time. As a result, the harvest is poorer and quality can also be seen injured. Maximums. That the two largest coffee producers reduce their production is something that affects the rest of the industry. On the one hand, Arabica coffee is the most coveted among specialty coffee producers and is usually more expensive, with Astronomical examples such as Geisha Café. On the other, although the robust is usually cheaper, specialty coffee is already being created with this variety and something more important: it is the basis of something as consumed as instant coffee. As a result, in the New York ICE bag, the Arabica increase 70% in 2024 and an additional 25% in the first months of this 2025. In the case of the robust, the record is got On January 31 with $ 5,840 per ton in the London Stock Exchange, with increases of up to 6% in a single day. Prices also increase for producers and exporters. As we read in Reutersall the main territories experienced increases in 2024 compared to the levels of 2023. And not small: Ethiopia 17.8%. Kenya 12.3%. Brazil 13.6%. Colombia 11.7%. Indonesia 15.9%. Vietnam 5.8%. Bit with delay. The problem is that the price does not rise for producers, toaster and exporters while for the customer. For example, prices achieved In the bag a few days ago they are those of the cargo that will be delivered in May of this year, and it will be from there when the ‘domestic’ price will continue to increase. And it will not be the last climb. In his last report About the state of coffee, the United Nations Food and Agriculture Organization -Fao- estimates that coffee prices increased 3.8% in December 2024 in Europe at a retail level, 6.6% in the United States. The dynamic is that a 1% increase in international coffee prices cause an increase of 0.24% at a retail level after 19 months, with 80% of the accumulated impact transmitted in the following 11 months. In the case of the United States, this 1% increase in the international price translates into an increase in the retail price of 0.20% after 13 months. In the case of the US, 80% of the accumulated impact is transmitted in eight months. “Inelastic”. This word is interesting, but it is simple to understand: it is the one that defines goods that do not have substitutes and that, therefore, no matter how the price increases, consumers will continue to buy them. Well, in its report, FAO ensures that “given the inelastic nature of coffee demand, it is unlikely that consumption decreases significantly in both markets” -American and European. That is, as there are no alternatives to coffee, no matter how much prices upload us, consumers will continue to acquire this product. Nor is there anything to intervene because, as FAO herself concludes, coffee consumption represents less than 1% of the annual household spending. From the US National Coffee Association they do not share this, affirming that “the great price increase eaten the liquidity of the customers. They do not have all the money to buy what they need” and ensure that they have sold 30% less of the production when, at this point, they would no longer have reservations. It all depends on three countries. Until now, we have talked about the increase in coffee price for wholesalers, but if we are going to the price that consumers pay, FAO estimates that, in December 2024, a coffee was 6.6% more expensive than in December 2023 in the United States. In the case of the European Union, the increase was 3.75%. Therefore, and taking into account that delayed coup of the price increase in coffee, it seems that the worst is yet to come. From FAO they see this as an opportunity for greater research in technology, research and development of the coffee sector and, above all, to increase the climate resilience of coffee. Although there are many coffee, Vietnam, Indonesia and Brazil producers are the authentic monsters of the great market, but climate change is leaving us two lessons. One is the one that is causing the scarcity and increase of current prices: more unpredictable climatic events on dates that unravel coffee cultivation, therefore affecting crops. On the other hand, it is also an opportunity. We are already seeing that there are those who insist on growing coffee outside Coffee beltwith coffee trees growing wildly in Sicily and Plantations in Andalusia or Catalonia They are testing the viability of growing coffee in such unavailable conditions. Final of the tunnel in sight? What is clear is that the world is thirst for coffee and, with a China increasingly passionate For this drink, it is urgent to have a much more stable stage. In Reuters We read that there are also those who take the … Read more

Spain was not one of the first to step on Antarctica, but now it has one of the most coveted laboratories on the continent

by

The Antarctica It is a huge frozen desert, but also one orUnique portunity for research. Spain is one of the more than 30 countries that have Bases in the territory And one of them, Gabriel de Castilla’s, has just been extended to be able to carry out a broader range of projects. The peculiarity is that its construction has been carried out in record time and will allow a boost to the investigation of the Climate change and the Biodiversity With a particularity: Spanish is one of the three clean laboratories on the continent. Only. We have been decades studying Antarctica From the air. Is what is allowing us to know What is it under that layer of icebut we also have been studying at Antarctica from the ground. He Antarctic Treaty of 1959 It is the one that allowed different countries to establish bases on the continent, exclusively for peaceful and scientific purposes. However, before that there were already bases such as Orcadas base from Argentina, which were operating continuously in the field. The reason is that it is a Single scenario For research. Not only for its diversity or for the dry atmosphere that allows to install advanced astronomical observatories, but because we can reconstruct the climate of hundreds of thousands of years thanks to the air bubbles trapped in the ice and, above all, it is a Climate change thermometer. Spanish Antarctica. We owe several findings to the field research, being one of the most notable the discovery of the ozone layer in 1985. As a result of those agreements, Spain could establish Two bases in Antarctica. The most veteran is the Juan Carlos i. It was inaugurated in early 1988 and is operated by the CSIC. It is not busy all year, but maintains automated records when there is no one and supports projects of areas such as biology, geology, weather and glaciology. The other is the Gabriel de Castillaopened a year later and operated by the Army. Its operation area is diverse, with research in the fields of earth sciences (geomagnetism, volcanic surveillance or geomorphology, among others), biological sciences (ecology, ethology or microbiology), environmental sciences (climate change) and disciplines such as physics, mathematics or biochemistry. Gabriel de Castilla. Like Juan Carlos I, this base is not always busy. Spanish work is limited to the months of the Southern summer, which occurs between December and March, and its location is unique because it is next to one of the two active volcanoes of Antarctica. This makes it a unique enclave to study geological processes and extreme ecosystems. But it seems that the base fell short, so a new scientific module has been built. In the upper image we see what the base was like. In the lower one, those small modules have been eliminated to leave the new space. Reform reforms. After an investment of two million euros, the Gabriel de Castilla has been able to expand its surface to about 307 m². Thus, he has been able to improve his equipment thanks to a microscope room, an electricity and electronic space, a sanitary module and a clean laboratory. And we might think that in such an extreme climate the construction would go slow, but no: in 70 days of the plane to having a structure that already expects research equipment. As points The army, 700 panels, 400 profiles, 26 screws and a total of 80 tons of material have been used to create a new module 41 meters long by 7.2 wide and another 7 high. In case you wonder, beyond the heating, the walls have a 50 millimeter polyurethane sandwich -type layer and another 60 millimeter inner layer of rock wool to improve thermal protection. Clean laboratory. But beyond the speed in its construction, the most important thing about the ‘new’ Spanish base in Antarctica is the aforementioned clean laboratory. It is a space designed to minimize external pollution, so research processes can be carried out in a practically aseptic space in which the samples are not contaminated with exterior agents. The protocols are very strict in both cleaning and ventilation and disinfection, and the really important thing is that, of the more than 30 bases present in Antarctica, that of the Gabriel de Castilla is one of the three Clean laboratories from the region. As they detail in This video From El País, it will be shared with Portugal, and one of the objectives will be to analyze pure samples to better understand the human impact on the planet without external interference.

A review of the cars of the millionaires Tech

by

Elon Musk, Mark Zuckerberg or Jeff Bezos have enough money as to drive any car that seems to them. However, not all of them demonstrate an excessive passion through the motor world and, for security reasonsvery few of them are allowed to drive their own cars. Some must settle for appreciating the beauty of their collections of supercar exposed as art pieces in His luxurious garages. Since these technological magnates were not always as rich as they are now, they have also led utilities without so many power horses, but with many more kilometers more behind them. We discovered what cars the heavyweights of technology have led throughout their lives. Elon Musk: Hurdly to arrive As expected, Tesla’s CEO is a big fan of its own vehicles. In 2019, Musk revealed in his X account That his favorite was the Tesla Model S Performance, although he has also led a Model 3 Performance and his security team usually uses the Model X for their displacements. Also assured have driven a Cybertruck after its launch. However, Musk’s passion for cars is not limited to Tesla. Your collection is much more varied. According The published by GQOne of his first cars was a BMW 310Iof 1978. With the first money he obtained with the investment round of ZIP2, the first company he founded with his brother Kimbal, Musk bought a Jaguar E-Type 1 Roadster Series, according to Walter Isaacson in The last biography of the millionaire. Nevertheless, The most representative Because of its meaning, McLaren F1 bought in 1999. The car was valued at more than one million dollars and acquired it after selling ZIP2 to Compaq for 307 million dollars, officially becoming a millionaire. The moment when he received that car I am immortalized In a video. “There are only 62 around the world and one of them is now mine,” said a very young Musk. Later, Musk would crash that car on a Los Angeles highway when he tried to show Peter Thiel that he was not afraid to risk during the merger process of his companies to give rise to PayPal. “It was a miracle that neither of them was injured,” assured Thiel a The New York Times. Jeff Bezos: The pragmatic Jeff Bezos is the second greatest fortune in the world, but one of the cars with which he is most related is neither a supercar nor a luxurious Berlina: it is a Honda Accord of 1991, at the same time that Amazon had an estimated capitalization of 30,000 million dollars and its fortune was about 1,000 million dollars. Like Bezos confessed At 60 minutes, “it’s a very good car.” Bezos drove that car until 2013 to go to Amazon offices. However, the millionaire treasures an impressive collection of exclusive supercar among which, according to Autobildthere is a Ferrari Sergio of limited edition of which there are only six copies; and a Bugatti Veyron link customized by the Mansory coach.

The greatest hidden potential of solar energy is not found in photovoltaic macrogranjas: it is on the roofs

by

Climate change is one of the hot potatoes that humanity must face at the moment. Although in recent years measures have been promoted to mitigate our footprint, at the same time we have followed depending on fossil fuels that contribute to the temperature increase of the planet. The renewables And, specifically, the solar energy It is postulated as technology that can help us reduce these emissions. And a study published in Nature He points out that there is something better than filling the field of solar farms: the photovoltaic of roof. Limit. In 2015, the Paris agreement launched an ultimatum: the temperature increase had to be limited Global to less than 1.5 or 2 degrees Celsius. They soon left reports that were not nor close to getting it And I know He pointed out That, by the end of the century, the temperature increase would be 2.8 degrees. Since then, we have seen the impulse of an artificial intelligence that has needed to resort to fossil fuels or the Great oil company in the era of renewable transition. However, we have also seen the explosion of solar energy with Very cheap panels And every time more efficient. Next to wind, in 2023 provided 27% of EU electricity. Megagranjas. In fact, there are already countries that operate practically With renewable energies And, as we say, Solar plays a very important role in this story. Not surprisingly, in recent years we have seen the pharaonic photovoltaic farm deployment capable of generating a lot of energy. China goes to the head with plants that They look from spacebut there are few countries that already have huge areas of land dedicated to these panels or with in progress. However, there are those who think we can do better with the photovoltaic. RPV. They are the acronym of ‘Rooftop Photovoltaic’, or ‘PHOTOVOLTAICA DE ALBOTEA’, and according to a study by the University of Sussex, it would be the solution to stop gaining ground to the field with solar panels and take advantage of something we do not take advantage of today: millions of roofs. According to their accounts, made through geospatial data and artificial intelligence models, the roofs cover more than 286,000 km² of the planet. To put it in perspective, it is like the area of ​​countries like Italy that yes, it may not seem too much, but imagine a solar farm of the size of … well, from Italy. The orange areas represent 1,724 strategically selected cities for the development of predictive models with the aim of estimating the global roof surface Staked to fossil fuels. According to researchers, taking advantage of roof Electricity consumed every year), which would allow to almost completely replace fossil fuels. Not only should the plates be installed, but also adequate battery systems. According to its calculations, if that amount of territory was covered with solar panels, the global temperature could be reduced between 0.05 and 0.13 degrees before 2050. Beyond that gain, Felix Creutzig -one of the researchers at the University of Sussex -, considers that it would also contribute to having a cleaner air and greater energy safety, since we would be covered before specific demand peaks. Roof area in km² at macroregional and national scale Areas with potential. And, obviously, the plan would not go well if these panels are placed without ton or they are. In the study, it states that the ideal area to fill the roofs of buildings with solar panels is that of East Asia. The reason is the great density of buildings and the conditions of the area in terms of solar radiation. North America and Europe also have great potential and, combined, these roof plates would generate more than 4,300 GW. In perspective, it is about a quarter of global capacity. Another advantage would be the decentralization of energy, making countries less vulnerable to energy and geopolitical crises. Africa would also be a good site, but the problem is that the territory currently represents only 1% of photovoltaic facilities due to deficiencies in energy services and dependence on fossil fuels. Stick to Nuclear. But well, we are currently burning coal when we need fast energy to satisfy the peaks, but we also have nuclear. So much that there are countries that have not only expanded the useful life of their centrals, but the closing decision of those already have to produce energy for a few more years. As we read in PV-MagazineCreutzig affirms that “with an unleashed solar potential, it is difficult to understand how governments justify investment in nuclear energy or carbon capture projects that have not yet been proven.” However, although nuclear also has its advantages over the use of fossil fuels, such as its power or stability, it is evident that the calculations of Sussex researchers are very interesting in order to take advantage to generate energy spaces that, right now, are underutilized. And be careful, it does not only stay in a study, since the University of Sussex has been testing This on the roofs around them.
