Many people wake up between two and three in the morning. And science already knows what they have in common

May 19, 2026 by usatoday24

Waking up in the middle of the night can be a pleasant experience when we look at the clock and see that we still have several hours of sleep left. dream. However, for many people it can become a frustrating routine that reduces their ability to achieve restful sleep. It is therefore likely that people may wonder why this happens and to what extent it can be prevented. Many things can wake us from our sleep at night. From a mosquito stalking our bed to serious cases of insomnia. Each circumstance may have its particular characteristics, but in any case, a significant part of the population ends up waking up at some point during the night with some frequency. And why does it happen? Beyond the external factors, there are two internal processes related to this. The first is the circadian rhythm, and the second is the sleep cycle. The circadian rhythm refers to “biological clock“which tells us the sleep and wake cycles. It is a collection of biological processes that activates us throughout the day and prepares us for sleep in the afternoon and night. It does so through substances such as melatoninthe “sleep hormone” that transmits this information between different parts of our brain. Our body takes advantage the light we perceive as an indicator of when to secrete melatonin or not. The sleep cycle, for its part, refers to a series of stages that occur and repeat throughout our daily sleep. A night of sleep has between four and six sleep cycles, each with four stages: a REM (rapid eye movement) stage; and three non-REM stages, each deeper than the last. Although the cycles are repeated in their structure, each of the four phases can have greater or lesser presence in each cycle. In the first cycles, the deeper stages predominate. That is why from the first hours of sleep it is easier to wake up and more difficult to fall asleep again. However, there are numerous factors that can affect how often we wake up at night more or less frequently. It is about both internal and external circumstances that can affect our circadian rhythm or our sleep cycle. The age It is one of the main factors. Over time our circadian rhythms changejust like our need for sleep. Age is a determining factor to the point that older people can have their sleep interrupted up to four times a night. The menopause It can also affect our ability to sleep straight through (as well as pregnancy). Age is also linked to nocturiathe interruption of sleep caused by the need to go to the bathroom. Our psychological state can also affect. Stress, as well as disorders related to anxiety either depression They can have a negative effect on our quality of sleep. This is bad news if we take into account that poor sleep quality can aggravate these problemswhich has the potential to generate a vicious cycle. From a mild headache to chronic painphysical pain can also affect our sleep. Like some medications such as beta-blockerscorticosteroids, antidepressants or diuretics They can negatively affect our sleep. How to avoid interruptions Understanding the causes of our sleep problems can serve as the first step to solving them. Adapting to changes in our body can be complicated, but some general guidelines They can also be useful. Guidelines such as correct “sleep hygiene”. Something that can help us is to introduce changes to our schedule. The usual recommendations in this regard usually begin by maintaining regular schedules, going to bed at “prudential” hours, that is, ones that allow us to achieve the recommended seven or eight hours of sleep. Another habit change can happen eliminate nap. Napping can negatively affect our night’s sleep. However, in this sense, science tends to consider that the differences between individuals are high, so there may be important differences from person to person. Another important guideline is to avoid screens or other blue lights in the last hours of the day. Physical activity can also help, although it is usually recommended not to leave it until the last hours of the day. That is, not exercising before going to bed. Eliminating alcohol and tobacco in our daily lives can also help us improve our sleep. Many of the techniques that aim to help us sleep are relaxation techniques. These can also help us so that sleep interruptions do not result in hours of lost sleep. “Empty” our thoughts in a notebook before going to bed, controlling our breathing… these are ways to prevent our stress from affecting our sleep. Lack of sleep and rest has important effects on our physical health and our mood. It is not surprising therefore that it is an issue that worries Spaniards more and more, to the point of becoming one of the countries with increased drug consumption to sleep like benzodiazepines. Like any other health problem, many times treating it is not in our hands but rather health experts must be the ones to tell us the appropriate guidelines to solve our problem. Of course, taking the first steps towards a better dream is still in our hands. In Xataka | There are people who sleep four hours a day and are still functional.

late night cafes for crying babies

May 19, 2026 by usatoday24

Japan may have few babies (of course many fewer than the authorities would like), but that does not mean that caring for them is easy. Especially for families for whom conciliation is difficult. To solve it in some locations in the country, an idea has begun to take shape: the yonakigoya or “cry night cafes”, places where parents (basically mothers) can go when their babies won’t let up and make them spend a sleepless night crying and lonely. In the yonakigoya Not only do they find places to sing lullabies without disturbing other family members who will have to get up early to face exhausting days of work. The idea is that they also serve as support networks and reach places where administrations do not. “Crying coffees”? Exact. They sound like science fiction. And it makes perfect sense that this is the case because the concept came from a manga published in 2023a work that talks about a place called Yonakigoya (‘House of Night Cry’) that serves as a refuge for mothers who are overwhelmed by the crying of their little ones. Straits Times assures that the author was speaking from her own experience and that she shared the idea for the first time online in 2017. The reception there was so good that she decided to reserve a place for it in her work. Something more than fiction. Beyond when, how and where the idea arose, what is undeniable is that the concept of yonakigoya It has penetrated Japanese society enough to make the leap from fiction to reality. It has revealed Kyodo Newsone of the most popular news agencies in the country. A few days ago, its reporter Maki Shinozaki published a report on how the phenomenon of late-night “cry coffees” is expanding throughout the country. The piece has been echoed by media around the world, from newspapers the Sanyo News either Sankei Shimbum to the british The Times. Between toast and books. The yonakigoya They seem to have more of a support network than places that seek to make money from the cries of babies and the anguish of their parents. In fact, in Hokkaido The service is provided in a cafeteria specializing in French toast that has decided to open certain nights a month to help mothers, in Tokushima there is another support center that organizes “coffees for crying children” every month and in Aichi a bookstore has decided to join the bandwagon by organizing evenings for babies. In the first case (the cafeteria) the premises open for free between 9:00 p.m. on Sunday and 6:00 a.m. on Monday and in the latter (the bookstore) the service is provided with the help of volunteers such as teachers or midwives from 8:30 p.m. to 12:00 p.m. Although Kiodo News and the Japanese media report only certain specific cases (which suggests that it is not a mass phenomenon), a quick search on Google shows that the concept generates interest and expands. For babies… and adults. At the French toast cafe in Hokkaido they have installed mats for babies to crawl and (hopefully) sleep, as well as spaces reserved for breastfeeding and diaper changes. However, usually yonakigoya They only look after the children. They also do it for the adults who arrive with them. The idea is that they serve as support for parents, mainly women, who are those who use them the mostespecially during their maternity leaves, while their husbands sleep before facing long days of work. Although the country has taken steps towards a labor model that allow conciliationat the end of 2024 the Government published a report which revealed that 10.1% of men and 4.2% of women work more than 60 hours per week. In the country it has even become sadly popular ‘karoshi’ conceptdeath from overwork. “A refuge”. Madoko Nozawa, owner of the toast cafe that is converted into yonakigoya Sunday mornings, has explained to Kyodo who decided to embark on the project inspired by her own experience. She is also a mother and in her day, she remembers, she spent sleepless nights because her baby wouldn’t stop crying and her husband had to get up early the next day. “I want this to be a refuge where people can feel like they are not alone in their struggles,” share. “While I was trying to put my children to sleep, I couldn’t move and felt totally overwhelmed,” points out another mother to whom the newspaper Chunichi Shimbun interviewed in the bookstore-yonakigoya from Aichi Prefecture. “I still don’t have many people I can talk to naturally about parenting. A place like this is a source of support.” A critical note. Although the yonakigoya They demonstrate Japan’s ability to create support networks, their success also leaves some critical readings. To begin with, the fact that those who use them are mostly women reveals that parenting still falls largely on them. It’s nothing new. In 2022 the Association of Medical Colleges of Japan published a study on childcare among doctors that revealed a significant gender gap: 31.8% of female doctors with children acknowledged that they shouldered 100% of the childcare and 55.2% estimated that they assumed more than 80% of the tasks. Among men, these percentages were respectively 8.4 and 14.5%. In the middle of the crisis. Another critical observation brings it Kaori Ichikawa, professor at the Tokyo University of Information Sciences, who points out the paradox that in the midst of demographic crisis and despite the huge amount of resources that the Government is allocating to promoting births, it must be the private and community initiative that cares for mothers at night. “Government support is often limited at night, weekends and holidays, so the public and private sectors must work together to create places like late-night cafes, where they can seek help when they need it,” claims.

Your main competitor in chip manufacturing is your greatest ally

May 19, 2026 by usatoday24

Approximately 30% of Intel chips It is manufactured outside of its semiconductor plants. And most of these ICs are produced by TSMC. This Taiwanese company is the largest chip manufacturer on the planetand therefore it is also Intel’s main competitor in the market for custom semiconductor manufacturing for third parties. Despite this, Intel is deeply dependent on TSMC. Currently, the latter company manufactures Intel’s most advanced integrated circuits in those nodes where the company led by Lip-Bu Tan has not yet reached optimal wafer performance. The CEO of Intel has confirmed recently that his company is also outsourcing the production of those chips that have frequent demand peaks, and which, therefore, is not able to manufacture in sufficient quantities to satisfy the needs of its customers. TSMC is producing Intel’s entire Lunar Lake line, and most of Arrow Lake as well. In addition, Intel is one of the first clients of this Taiwanese company with access to 2nm node latest generation. In fact, TSMC has already started production testing of the compute tile of Nova Lake at its Hsinchu plant, and large-scale manufacturing should begin before the end of 2026. During Intel’s latest financial results presentation, Tan confirmed something indisputable: TSMC is an essential partner of your company. TSMC also depends on Intel Intel’s current dependence on TSMC is a consequence of the delay accumulated for years in the development of its manufacturing nodes, before the arrival of Lip-Bu Tan. In fact, the delays in the jump to 10 nmand later the 7nmcontributed to TSMC overtaking Intel from a technological point of view. In addition, dependence on Intel is also based on the need to cover short-term demand. The dependence on Intel is based on the need to cover short-term demand This scenario clearly reflects that Intel and TSMC are competitors. But they are also partners. In fact, few people know that Intel sells chip manufacturing equipment to TSMC. Pat Gelsinger confirmed itthe former CEO of Intel, at the end of 2024 during a meeting with his investors: “TSMC is an impressive company. They serve their customers well, and they serve us well. Lunar Lake would not exist without TSMC (…) But we also supply them with some of our advanced equipment. “It is a complex relationship that is important for Intel, for TSMC and for the entire industry,” Gelsinger explained. It is clear that the former CEO of Intel wanted to convey positivity with this statement, and, to the extent possible, defend his management. We all know how it ended. Be that as it may, there is no doubt about one thing: Intel’s dependence on TSMC is not temporary; It is structural. It is the result of years of technological delays, is maintained by TSMC’s superiority in mature advanced nodes and has been consolidated as part of a strategy that prioritizes flexibility over in-house production.

We thought AI was laying off engineers. In reality, it has pilloried another profile: middle management.

May 19, 2026 by usatoday24

We’ve been hearing for several years that AI was going to change work as we know it. What perhaps no one anticipated is that the first mass casualty They would not be factory operators or data analysts, but the layer of professionals that holds together the structure of any company: middle management. The phenomenon is already leaving a trail of layoffs with the successive restructurings that the big technology companies have been applying for the last year. Departments are reduced by the implementation of AI and become increasingly autonomous in decision-making, so the intermediate step that united everything becomes unnecessary. The profile that worries the most. Middle managers have been acting as a transmission belt between the management that dictates strategies and the teams that execute them for decades. The function of these positions was to collect data, synthesize it, transfer decisions and coordinate day-to-day operations. That intermediary job is exactly the role that AI is automating most easily, making middle managers the most important link. likely to be fired in that chain because it is not related to either decision-making or their execution. The pressure on this intermediate profile has been building for some time and the data confirms it. By the end of 2025, job offers for middle managers in the US were 42% lower to the maximum recorded three years earlier, according to Revelio Labs. The consulting firm Gartner calculated that by 2026 one in five companies will use AI to eliminate more than half of their middle management positions. Companies are applying it. Just a few weeks ago, Block, the payments company founded by Jack Dorsey, announced the dismissal of 40% of its staff and presented a new organizational model in which AI assumes the role of a link between teams. In one later blog postDorsey and councilor Roelof Botha explained this move: “There is no need for a permanent layer of middle management.” Brian Armstrong picked up Dorsey’s baton in your ad of dismissal for 14% of the Coinbase workforce, specifying that the intermediate positions were going to disappear as such and that they were now going to contribute by “getting their hands dirty with their teams.” What is lost when a link disappears. In statements to GuardianFreeland Abbott, former CTO of Square, warned that “AI cannot provide team motivation, human connection, and support the way a person can,” removing the human component from middle management in companies. Furthermore, the elimination of this role could mean another obstacle in promotion options for junior employees, who usually find those opportunities by starting to manage the work of other junior employees as they gain experience. According to the study By Anastassia Fedyk, a professor at the Haas School of Business at the University of California, Berkeley, as AI tools allow more work to be shifted from managers to their subordinates, these structural changes could become permanent. Rehire middle management. Matthew Bidwell, professor of management at the Wharton School of the University of Pennsylvania, assured on his podcast on the labor market that there are precedents of companies that tried eliminate intermediate hierarchies and they ended up turning back. According to their analysis, middle managers are in an especially vulnerable position in restructurings because it is more difficult for them to demonstrate their value to management. Far from putting an end to the “productive” positions held by engineers and administrators, AI seems to have opened the door and the piece that is being most affected to the point of placing it as a species at risk of extinction are middle managers. Above all, after his post-pandemic proliferation. In Xataka | Generation Z is avoiding promotions to mid-level positions: too much stress and too little reward Image | Unsplash (Austin Distel)

With AI saturating TSMC’s factories, there’s someone ready to take over: Chinese foundries

May 19, 2026 by usatoday24

Semiconductor Manufacturing International Corp, or SMIC, is the backbone of the semiconductor industry in China. Together with Huawei, he is the architect of the great government plan so that Chinese companies and data centers stop depending on foreign chips that, since punch on the table given in mid-2023 with the SoC of Huawei Mate 60 Prohas called a lot attention on the international scene. So much so that SMIC itself points out that there are already foreign clients who are changing orders so that they can manufacture them themselves. The reason? In the midst of the semiconductor crisis, China is one of the few places with available production capacity. Bottleneck. SMIC, and Chinese foundries, are in a different war: volume over sophistication. While TSMC, Intel and Samsung are fighting for superiority in the 2 nanometer war, China does not seem interested in that battle of the advanced nodes. The reason is simple: they barely represent 20% of the global chip market and producing them is extremely expensive. That strategy of being out of the forefront of the spotlight is working out well for them. It is estimated that between January and February, China has exported integrated circuits worth more than 43 billion dollars. It represents a growth of 21.8% and the reality is that, at this time, China cannot compete in technology with the one that dominates the segment: TSMC. The Taiwanese company is developing the most advanced nodes for clients such as Nvidia and Apple and a few years ago they stated that they could not handle all the demand. Today, that demand has skyrocketed with AI and TSMC is already saying that there may not be something for everyone. That is why there are 64 new factories planned to unblock the situation, 58 of them located in China. Orders. Returning to SMIC, Zhao Haijun, the company’s co-CEO, pointed out a few days ago during the earnings call that China is one of the few regions that has manufacturing capacity, which is motivating “many foreign clients to redirect their orders.” This is not news if we take into account the world situationbut the manager assures that some of these products “were previously manufactured in foundries abroad and are no longer produced there.” That is the relevant point in all this, since it states that, although SMIC as the largest national foundry is receiving the largest burden of these orders, there are other smaller companies that are also benefiting from the situation. This situation is occurring out of necessity, out of TSMC’s need, according to data from TrendForce. Because the Taiwanese company plans to reduce part of its capacity in mature nodes (to focus on cutting-edge ones), it is diverting part of that production and excess orders to Chinese suppliers and second-line foundries. This will also cause the wafers to be used to the millimeter and that from an average utilization rate of 80% in eight-inch wafers, the industry will go to 90% in 2026. Chips are needed and they will have to be scraped from wherever they can. domino effect. The situation is going well for a SMIC that reported revenues of 2,505 million dollars in the first quarter of this year, 11.5% year-on-year that will be surpassed in the second period of the year, with revenue growth of between 14% and 16%, well above the 7% that Wall Street expected. But it seems that not only SMIC is having good news within the current catastrophic situation in the components, memory and other segment. We already commented a few months ago that “crisis” could be synonymous with “opportunity” for the Chinese semiconductor industry because there were foreign manufacturers that were approaching them to have supplies, especially of RAM memories, which could cause the international flourishing of this industry traditionally overshadowed by the Samsung – SK Hynix – Micron trident. As we see in SCMPHua Hong is another Chinese foundry that is smaller than SMIC, but also saw its revenue grow 22.2% year-on-year due to increased wafer shipments and a higher average selling price. These companies that make NAND, DRAM and NOR memory chips are seeing their business grow, and analysts expect other domestic foundries focused on logic chips to also continue to grow over the coming months. not so untouchable. In any case, it is evident that the market leader continues to be TSMC, but if before it was an undisputed giant, now it is still that Goliath… for which its David is emerging. Several, in fact. Apple is no longer the preferred customer of a TSMC that has in mind Nvidia to your best ally and it has been ringing for a while that Intel could fill that spot in the heart of Apple. And, returning to 2 nanometers, AMD has been deeply involved in the battle for both consumer and AI segments for a few years and is looking for advanced chips. And, as in the case of Apple, since it is now Nvidia that has all the privileges of TSMC, AMD has looked a little further east to manufacture its 2nm chips. The lucky one? Samsung.

The big question behind the US visit to Beijing is not Taiwan. They are two Chinese SUVs with roofs that have fired the imagination

May 19, 2026 by usatoday24

The scene took place in 2018, during a military parade in Moscow. So several Western analysts spent hours trying to identify a strange russian truck covered by tarps and antennas of which no one offered explanations. Years later it was learned that it was part of one of the systems electronic warfare most advanced in the Kremlin. Since then, every rare vehicle that appears near a world leader has ceased to seem like a simple logistical eccentricity. Two SUVs and an uncomfortable question. For years, American presidential visits to Beijing revolved around the same topics: Taiwan, trade, sanctions or the military balance in Asia. However, they had TWZ analysts that in Donald Trump’s recent visit there was a detail that ended up attracting much more attention among military analysts and technological observers: two Chinese Hongqi SUVs with huge modified roofs that seemed to hide some kind of special system. They were not particularly elegant or discreet. In fact, they seemed heavy and strange. That is precisely why they attracted so much attention. The feeling they left is that China wanted teach something without showing it really. The big question after the trip was no longer just what Washington and Beijing had talked about, but what the hell exactly those vehicles were hiding. Modern warfare and protecting the sky. The most repeated theory links to something that we have been countingand these roofs could house electronic warfare systems, advanced communications or even anti-drone capabilities. The idea makes sense because the presidential caravans begin to face a relatively new problem: cheap drones capable of threatening even extremely protected world leaders. Ukraine, the Middle East and the Red Sea have shown that it no longer takes a sophisticated missile to create a huge security problem. That’s it forcing to transform VIP convoys in small fortresses mobile electronics. The Hongqi seen in Beijing fit perfectly in that trend: lots of interior space, extra weight and modifications probably designed to transport complex equipment rather than people. Caravan converted into a command center. The interesting thing is that those SUVs were not an isolated anomaly. The caravan also included Modified Suburbans, Lincoln Navigators, and Ford vans with antennas, sensors, and special roof structures. Everything suggested a mobile architecture of communications, surveillance and electronic interference much more sophisticated than usual. In practice, presidential convoys are beginning to look less like simple armored columns and more to command centers capable of operating in environments saturated with drones, electronic signals and autonomous threats. Not only that. Analysts recalled that China also used Hongqi vehicles, a brand very historically linked to Chinese political power, reinforces another important idea: Beijing wants to demonstrate that it can develop this type of strategic capabilities with its own national platforms. The new competition between powers. For a long time, the rivalry between China and the United States was measured with aircraft carriers, stealth fighters or hypersonic missiles. Now it’s starting to appear another competition quieter: who masters electronic and anti-drone protection in real scenarios. The recent wars have shown that nearby airspace has become extremely dangerous even far from the front. This requires protecting infrastructure, convoys and political leaders in completely new ways. In this context, a jamming system can be as important as traditional shielding. Beijing’s SUVs reflect precisely this change in mentality. Deliberately ambiguous message. Of course also, perhaps the most important thing is that no one really knows what those vehicles were transporting. And that uncertainty is probably part of the message. In today’s technological competition, projecting unknown capabilities is also a form of deterrence. The huge Hongqi roofs they seem designed to provoke questions rather than offer answers. Be that as it may, his appearance on a high-level presidential visit leaves a clear conclusion: while much of the world continues to look at Taiwan, Ukraine or Iran, China seems determined to teach discreetly something else. That the next great military revolution could not be in large visible platforms, but in mobile, discreet electronic systems prepared for a war dominated by drones. Now that Russia is about to fall in Beijing, it will be time to see if they show those SUVs again.

the idea is reminiscent of how macOS works

May 19, 2026 by usatoday24

The speed of an operating system is not always noticeable when we export a video or open a demanding game. Many times we perceive it in much smaller gestures: a menu that appears instantly or a window that responds without delay. It’s a hard feeling to sell on a spec sheet, but easy to notice when it fails. Microsoft has been trying to convey for months that it wants to improve Windows 11and one of its next adjustments goes right into that area where fluidity is gained or lost in tenths of a second. Low latency profile. Microsoft is testing what is known as low latency profile. The idea is to ask the processor for an additional boost of speed at specific times, such as when opening the Start menu, an application, or certain context menus. We are not facing a function announced as a great novelty for all users, but rather a setting present in test builds. Secure Windows Central who has already tested this profile and has observed an appreciable improvement in speed and response compared to the current public version of Windows 11 25H2. It’s not magic, it’s latency. The reference to macOS does not point to a specific Apple feature, but to a principle that, according to Scott Hanselman, vice president of Microsoft and GitHub, modern operating systems share. “All modern operating systems do this, including macOS and Linux,” wrote in X. Their argument is that this is not “cheating,” but rather a common way to make applications appear faster: temporarily raising the CPU speed and prioritizing interactive tasks to reduce latency. In other words, Windows 11 would be trying to react better in those seconds in which we most notice if the system is accompanying or lagging behind. Spot power. At first glance it may seem contradictory that asking more from the processor also helps to take care of consumption. But reality goes the other way: many modern chips are designed to exert intense effort for a very short period and then return to a low-power state. Applied to Windows 11, the goal would not be to keep the CPU accelerated, but rather to take advantage of a specific push when the system needs to respond to the user. The key is that this impulse does not last longer than necessary. The test has not convinced everyone. Some users criticized on social networks that Microsoft resorted to this type of CPU boost, understanding that it could increase consumption and reduce autonomy, or that the company was leaning too much on the hardware instead of better optimizing the software. Now, Microsoft does not present this adjustment as the only answer to the fluidity problems of Windows 11, but as one more piece within a broader work. Windows 11 also needs convincing. The interesting thing is that Microsoft isn’t just talking about making an animation go a little faster. The company has begun to publicly organize its progress around a very specific idea, its “commitment to Windows quality”, with posts tracking the status of several changes in testing, including a less loaded Widgets view, lower RAM usage, adjustments to the Windows Insider program, and more leeway to decide when updates are installed. The timing is not coincidental either.. All of this comes as Microsoft tries to push users and businesses towards Windows 11, with Windows 10 still installed on just over a quarter of the world’s Windows PCs, according to StatCounter. When I finish that free year of extended security updatesanyone who wants to remain protected will have to update the system, change equipment if their hardware does not meet the requirements of Windows 11, or pay for more support. For companies there is a little more margin, but not infinite: they will be able to purchase one or two additional years of updates, with a cost that will increase each year.

Let’s tell you What are the appliances that consume the most? in your home, so that you can keep it in mind and thus be able to use them with caution. Because we have examples like how your oven can spend about 65 refrigerators running at the same time, and they are things that are worth knowing. Of course, you should know that although they are appliances that consume a lot of power, they do it in a timely manner. They are not appliances that you will always have on, although that is precisely why it is advisable to know this consumption for those moments when we may be thinking about whether to use them or not. Appliances that consume the most at home Here you have the list made with different calculations of the Institute for Energy Diversification and Saving (IDAE)in addition to energy marketing companies such as Repsol either Naturgy. You must know that They are hourly consumption rangeswhat they consume every hour that you have them on. In addition, you should also know that the consumption range may vary depending on the appliance. Because this is the average, but then other factors such as the age of the device, its efficiency or its features can cause its consumption to vary significantly. In any case, here is the list: Ovens: between 2,000-3,000 watts Vitroceramics and induction hobs: between 1,500-6,500 watts Electric radiators: between 1,500-2,500 watts clothes irons: between 1,500-3,500 watts Electric thermoses: between 1,500-2,500 watts hair dryers: between 1,500-2,000 watts Cooking plates: between 1,500-2,000 watts Electric fryers: between 1,500-2,500 watts To give you context, a refrigerator with a high efficiency model can consume between 100 and 300 kWh per yearalthough other older or inefficient models may exceed 600kWh. Come on, they’re in something like between 30 and 90 watts per hour. Although in the long run this may cause it to consume more than others, it is advisable to take into account the consumption of other appliances that are not always on, so that you can better calculate when to use them depending on the rates you have contracted and their schedules.
